Revision of Hista Oiticica (Lepidoptera: Castniidae) and discussion on the validity of its subspecies

Diurnal Lepidoptera tend to have colorful and conspicuous wing patterns, which is the reason the first classifications of day-flying moths and butterflies were based mainly on wing color and pattern characters. This is the case with the Neotropical Castniidae, which are usually large and colorful day-flying moths. One classification listed 134 species in 32 genera while an alternate classification recognized 81 species. In this paper we examine the taxonomic structure of the genus Hista Oiticica. It is the purpose of this paper to evaluate taxonomically useful characters besides wing pattern with the goal of classifying the taxa of Hista rather than classifying the variation of its wing pattern. In so doing, the results resolve the differences between the two proposed classifications of Hista. In addition, a lectotype is designated for Castnia boisduvalii Walker, 1854 (new synonym of Castnia fabricii Swainson, 1823) to ensure the stability of the name. Other new synonyms are proposed for C. fabricii (C. papagaya Westwood, 1877) and Castnia hegemon Kollar, 1839 (C. menetriesi Boisduval, [1875] and C. hegemon variegata Rothschild, 1919).

The identity of Sertularia reptans Linnaeus, 1758 (Bryozoa, Candidae)

This paper includes a reassessment of Scrupocellaria reptans (Linnaeus, 1758) (basionym Sertularia reptans), the lectotype of which is selected and figured from among herbarium-sheet specimens held at the Linnean Society of London. Material previously assigned to S. reptans was examined, providing morphological characteristics to distinguish Scrupocellaria ellisi n. sp. Scrupocellaria reptans has a geographically limited distribution in the United Kingdom, while S. ellisi is more widespread in the North Sea, Northeast Atlantic, Adriatic and Tasmania.

TAXONOMY OF THE SOUTH AMERICAN DWARF BOAS OF THE GENUS TROPIDOPHIS BIBRON, 1840, WITH THE DESCRIPTION OF TWO NEW SPECIES FROM THE ATLANTIC FOREST (SERPENTES: TROPIDOPHIIDAE)

A taxonomic study on the South American dwarf boas of the genus Tropidophis revealed the existence of two new species in the Atlantic Forest bionic. As a result, we recognize five mainland species, three in the Atlantic Forest and two in northwestern South America. Based on general distribution and morphological orientation, the type locality of T. paucisquamis is restricted to Estacao Biologica de Boraceia (EBB), municipality of Salesopolis, state of Sao Paulo, Brazil; furthermore, a lectotype for T. taczanowskyi is designated. We provide data on the hemipenial morphology of two South American Tropidophis, showing that the quadrifurcate condition described for West Indian taxa also occurs in mainland congeners. The distributions of the three Atlantic Forest species are congruent with patterns of diversification of other vertebrate taxa associated with cold climates prevalent at high elevations. Refugial isolation and riverine barriers may account for such speciation events.

Discovery and redescription of type material of Nausithoe simplex (Kirkpatrick, 1890), comb. nov (Cnidaria: Scyphozoa: Coronatae: Nausithoidae) from the North Atlantic

With discovery and examination of type specimens in the Natural History Museum, London, UK, we reassign Stephanoscyphistoma simplex (Kirkpatrick, 1890) to the genus Nausithoe Kolliker, 1853, as Nausithoe simplex, comb. nov., and designate a lectotype for the species. Use of morphometric measurements is considered important in coronate systematics, but key features also include the unique whorl of internal cusps and the shape of these cusps. All previous records of N. simplex must be re-evaluated, taking into consideration the morphology of these internal cusps.

Catalogue of the type material of Neriidae (Diptera, Schizophora) in the collection of the Museum fur Naturkunde Berlin, Germany

The Diptera collection of the Natural History Museum Berlin holds one of the most important collections of Neriidae. In this paper, the type specimens (holotypes, lectotypes, paratypes, paralectotypes, syntypes) of this historical collection are listed. 28 species-group taxa are dealt with. A lectotype designation is made for the species Brachantichir purpusianus Enderlein, 1922 in order to fix the identity of the name. Holotypes are recognized by monotypy of the species Chaetomeristes bullatus Enderlein, 1922; Chaetomeristes peruanus Enderlein, 1922; Derocephalus angusticollis Enderlein, 1922; Glyphidops limbatus Enderlein, 1922; Longina abdominalis Wiedemann, 1830; Loxozus clavicornis Enderlein, 1922; Oncopsia mexicana Enderlein, 1922; Paranerius fibulatus Enderlein, 1922; Telostylinus dahli Enderlein, 1922; Telostylus latibrachium Enderlein, 1922; and Telostylinus luridus Enderlein, 1922. Syntypes are labelled and listed for Brachantichir robusta Enderlein, 1922; Nerius terebratus Enderlein, 1922; Odontoloxozus punctulatus Enderlein, 1922; Telostylinus apicalis Enderlein, 1922; Telostylinus obscuratus Enderlein, 1922; and Telostylinus ornatipennis Enderlein, 1922. The account concludes with geographic and taxonomic summaries; an appendix listing the abbreviations, localities, and collectors cited in the text; and a bibliography.

Revision of Nanophareus, a mysterious harvestman genus from Chile, with descriptions of three new species (Opiliones: Laniatores: Gonyleptidae)

The Chilean genus Nanophareus Roewer, 1929 is revised and three new species are described: N. araucanus sp. nov. (type locality: Parque Nacional La Campana, Valparaiso, Chile); N. bipartitus sp. nov. (type locality: Parque Nacional La Campana, Valparaiso, Chile); N. bosqenublado sp. nov. (type locality: Parque Nacional Fray Jorge, Coquimbo, Chile). The type species, N. palpalis Roewer, 1929, is redescribed and a lectotype is designated. A cladistic analysis was performed using these three new species plus N. palpalis and 14 more laniatorid species, and a data matrix of 72 characters: Seven from the ocularium, 22 from the dorsal scutum, one from the venter, one from the chelicera, eight from the pedipalp, 24 from male legs, and nine from male genitalia. Two equally most parsimonious trees were found (L = 210; C.I. = 0.41; R.I. = 0.51). Nanophareus was recovered as nested within a paraphyletic subfamily Pachylinae. The genus Nanophareus was found to be monophyletic based on the following exclusive synapomorphies: An external row of enlarged tubercles inserted among small ones on lateral margin of the dorsal scutum (innapplicable in N. bosqenublado); the ventro-basal margin of pedipalpal tibia curved 90 degrees in lateral view; and retrolateral seta of the pedipalpal tibia with a socket apically bifid (socket and seta longer than pedipalpal tibia length).

On some species of Taeniotes Audinet-Serville, 1835 (Coleoptera: Cerambycidae: Lamiinae)

Taeniotes farinosus (Linnaeus, 1758) is a species that has been confused with other species during the past two centuries. In this work we demonstrate that Taeniotes farinosus sensu auctorum is not the species described by Linnaeus and designate a lectotype to establish its identity. Taeniotes pulverulentus (Olivier, 1790), currently synonymous with T. farinosus, is revalidated. Taeniotes guttullaris Schwarzer, 1929 and T parafarinosus Breuning, 1971 are junior synonyms of T. pulverulentus; Lamia subocellata Olivier, 1792 (= Taeniotes subocellatus) is a junior synonym of Cerambyx farinosus (= T farinosus). Additionally we monnei, a new species from Brazil and Argentina, is described and figured. Taeniotes peruanus provide annotated bibliographic references to T. farinosus and T pulverulentus. Taeniotes Breuning 1971 is figured for the first time.

Scorpiodinipora costulata (Canu & Bassler, 1929) (Bryozoa, Cheilostomata), a taxonomic and biogeographic dilemma: complex of cryptic species or human-mediated cosmopolitan colonizer?

Despite implausible cosmopolitanism, the species Scorpiodinipora costulata (Canu & Bassler, 1929) has been attributed with reservations to small encrusting colonies with similar morphological features whose known distribution is scattered in tropical and subtropical seas: Pacific Ocean (Philippines), Indian Ocean (Oman), Red Sea, SE Mediterranean, SE Atlantic (Ghana) and SW Atlantic (Brazil). This material raised questions about its generic assignment. The genus Scorpiodinipora Balavoine, 1959 is redescribed with Schizoporella costulata Canu & Bassler, 1929, from the Philippines as the type species, as Balavoine misidentified the specimens to define the genus as Cellepora bernardii Audouin, 1826. Moreover, SEM examination of the cotypes of S. costulata showed that Canu & Bassler confused two genera among them. A lectotype and paralectorype were thus chosen from Canu & Bassler's syntypes corresponding with the present morphotype. Hippodiplosia ottomuelleriana var. parva Marcus, 1938, from Brazil, which presents the same morphotype, is provisionally considered as the junior synonym of S. costulata. Considering the broad allopatric distribution of this morphotype across the oceans and the low capacity of dispersal of species with short-lived larvae, it is likely that this material includes several sibling species. However, the role of man-mediated dispersal is not excluded, at least in regions with high shipping activity, such as that comprising the Suez Canal.

A review of the genus Speocarcinus Stimpson, 1859 (Crustacea: Brachyura: Xanthidae), with a key to its species and the description of one new species

Speocarcinus dentatus n. sp. is described from the southwestern Atlantic. The new species can be easily separated from its congeners by a suite of carapace and appendage characters. Speocarcinus Stimpson, 1859, now includes eight extant species, all from the Atlantic or Pacific coasts of the Americas. Additional characters to further differentiate between S. carolinensis Stimpson, 1859, and S. lobatus Guinot, 1969, and between S. granulimanus Rathbun, 1894, and S. spinicarpus Guinot, 1969 are documented. The lectotype of S. granulimanus is first described and a key to the species of Speocarcinus is provided.

A new species of Leporinus Agassiz, 1829 from the upper Rio Paraná basin (Characiformes, Anostomidae) with redescription of L. elongatus Valenciennes, 1850 and L. obtusidens (Valenciennes, 1837)

Leporinus obtusidens Valenciennes, 1837 and L. elongatus Valenciennes, 1850 are redescribed based on the type specimens, including those of their junior synonyms, and recently collected specimens. Leporinus obtusidens is considered to be widespread, occuring in the river drainages of La Plata, São Francisco, and Parnaíba. Leporinus aguapeiensis Campos, 1945, described from the upper Rio Paraná, and L. silvestrii Boulenger, 1902, described from the Rio Paraguay, are considered junior synonyms of L. obtusidens. Leporinus elongatus is endemic to the Rio Jequitinhonha and Rio Pardo, two eastern Brazilian river basins, and the locality cited for the lectotype, Rio São Fransico, likely to be erroneous. Leporinus crassilabris Borodin, 1929, and L. crassilabris breviceps Borodin, 1929, both described from the Rio Jequitinhonha, are considered junior synynoms of L. elongatus. A new species of Leporinus, endemic to the upper Rio Paraná, very similar and sometimes mistaken with L. obtusidens, is formally described. In addition, comments on Leporinus pachyurus Valenciennes, 1850 and on L. bimaculatus Castelnau, 1855 are provided, and a lectotype for L. bimaculatus is selected.

Contribuição para o estudo dos Rhinotragini (Coleoptera, Cerambycidae). VI. Ecliptoides Tavakilian & Peñaherrera-Leiva, 2005

The genus Ecliptoides Tavakilian & Peñaherrera-Leiva, 2005, recently revised by Clarke (2009) to include three Bolivian species, is brought up-to-date by the inclusion of further South American species transferred from Eclipta Bates, 1873, and Odontocera Audinet-Serville, 1833. Three new species are described from Brazil: E. schmidi, E. tavakiliani, and E. hogani. Ommata eunomia var. rufula Melzer, 1934, and Ommata (Eclipta) plaumanni Fuchs, 1961, are revalidated and considered species of Ecliptoides. Species transferred from Eclipta to include Ecliptoides: E. bivitticollis (Fisher, 1952); E. eunomia (Newman, 1841); E. pilosipes (Peñaherrera-Leiva & Tavakilian, 2004); E. fanchonae (Tavakilian & Peñaherrera-Leiva, 2003); E. giuglarisi (Peñaherrera-Leiva & Tavakilian, 2004); E. vasconezi (Peñaherrera-Leiva & Tavakilian, 2004); E. vicina (Melzer, 1927); E. lauraceae (Peñaherrera-Leiva & Tavakilian, 2004); and E. bauhiniae (Peñaherrera-Leiva & Tavakilian, 2004). Species transferred from Odontocera to include Ecliptoides: O. quadrivittata Melzer, 1922; O. pusilla Gounelle, 1911; and O. monostigma (Bates, 1869). New synonymy: Ommata (Eclipta) collarti Fuchs, 1959 = Odontocera pusilla Gounelle, 1911 (= Ecliptoides pusillus). Lectotypes are designated for Ommata (Eclipta) vicina, and Ommata (Eclipta) collarti. New distribution records are provided for E. eunomia, E. pilosipes, E. plaumanni and E. fanchonae. A key to the species of Ecliptoides is given.

On the morphological differentiation between Libinia spinosa and L. ferreirae (Crustacea: Brachyura: Majoidea: Epialtidae)

Libinia spinosa H. Milne Edwards in Guérin, 1832 and L. ferreirae Brito Capello, 1871, inhabit very similar environments, and their geographic and bathymetric distributions overlap for about 3000 km along the southwestern Atlantic. Both species are commonly caught in the same haul and differentiating between them can often be difficult. Traditionally, morphological differentiation between L. spinosa and L. ferreirae has been based exclusively on the number of spines along the median, longitudinal line of the carapace and the development of a process at the anterolateral angle of the basal segment of the antenna. Because Libinia spinosa and L. ferreirae share similar numbers of median spines (7 and 6, respectively), and the number of median spines of the carapace and the process at the anterolateral angle of the basal antennal segment are variable, they are of little value in separating these species. It is shown herein that unequivocal identification can be easily achieved based on features of the male and female thoracic sternum, pereiopod dactyli, and infraorbital notch. A lectotype is designated for L. spinosa and its authorship and date are corrected. Libinia gibbosa A. Milne-Edwards, 1878, is demonstrated to be a junior synonym of L. ferreirae. The holotype of L. gibbosa is figured for the first time.

Systematics of the Oswaldoi Complex (Anopheles, Nyssorhynchus) in South America

Abstract Background Effective malaria control relies on accurate identification of those Anopheles mosquitoes responsible for the transmission of Plasmodium parasites. Anopheles oswaldoi s.l. has been incriminated as a malaria vector in Colombia and some localities in Brazil, but not ubiquitously throughout its Neotropical range. This evidence together with variable morphological characters and genetic differences supports that An. oswaldoi s.l. compromises a species complex. The recent fully integrated redescription of An. oswaldoi s.s. provides a solid taxonomic foundation from which to molecularly determine other members of the complex. Methods DNA sequences of the Second Internal Transcribed Spacer (ITS2 - rDNA) (n = 192) and the barcoding region of the Cytochrome Oxidase I gene (COI - mtDNA) (n = 110) were generated from 255 specimens of An. oswaldoi s.l. from 33 localities: Brazil (8 localities, including the lectotype series of An. oswaldoi), Ecuador (4), Colombia (17), Trinidad and Tobago (1), and Peru (3). COI sequences were analyzed employing the Kimura-two-parameter model (K2P), Bayesian analysis (MrBayes), Mixed Yule-Coalescent model (MYC, for delimitation of clusters) and TCS genealogies. Results Separate and combined analysis of the COI and ITS2 data sets unequivocally supported four separate species: two previously determined (An. oswaldoi s.s. and An. oswaldoi B) and two newly designated species in the Oswaldoi Complex (An. oswaldoi A and An. sp. nr. konderi). The COI intra- and inter-specific genetic distances for the four taxa were non-overlapping, averaging 0.012 (0.007 to 0.020) and 0.052 (0.038 to 0.064), respectively. The concurring four clusters delineated by MrBayes and MYC, and four independent TCS networks, strongly confirmed their separate species status. In addition, An. konderi of Sallum should be regarded as unique with respect to the above. Despite initially being included as an outgroup taxon, this species falls well within the examined taxa, suggesting a combined analysis of these taxa would be most appropriate. Conclusions: Through novel data and retrospective comparison of available COI and ITS2 DNA sequences, evidence is shown to support the separate species status of An. oswaldoi s.s., An. oswaldoi A and An. oswaldoi B, and at least two species in the closely related An. konderi complex (An. sp. nr. konderi, An. konderi of Sallum). Although An. oswaldoi s.s. has never been implicated in malaria transmission, An. oswaldoi B is a confirmed vector and the new species An. oswaldoi A and An. sp. nr. konderi are circumstantially implicated, most likely acting as secondary vectors.

Systematics, phylogeny and biogeography of Juncaginaceae

I investigated the systematics, phylogeny and biogeographical history of Juncaginaceae, a small family of the early-diverging monocot order Alismatales which comprises about 30 species of annual and perennial herbs. A wide range of methods from classical taxonomy to molecular systematic and biogeographic approaches was used. rnrnIn Chapter 1, a phylogenetic analysis of the family and members of Alismatales was conducted to clarify the circumscription of Juncaginaceae and intrafamilial relationships. For the first time, all accepted genera and those associated with the family in the past were analysed together. Phylogenetic analysis of three molecular markers (rbcL, matK, and atpA) showed that Juncaginaceae are not monophyletic. As a consequence the family is re-circumscribed to exclude Maundia which is pro-posed to belong to a separate family Maundiaceae, reducing Juncaginaceae to include Tetroncium, Cycnogeton and Triglochin. Tetroncium is weakly supported as sister to the rest of the family. The reinstated Cycnogeton (formerly included in Triglochin) is highly supported as sister to Triglochin s.str. Lilaea is nested within Triglochin s. str. and highly supported as sister to the T. bulbosa complex. The results of the molecular analysis are discussed in combination with morphological characters, a key to the genera of the family is given, and several new combinations are made.rnrnIn Chapter 2, phylogenetic relationships in Triglochin were investigated. A species-level phylogeny was constructed based on molecular data obtained from nuclear (ITS, internal transcribed spacer) and chloroplast sequence data (psbA-trnH, matK). Based on the phylogeny of the group, divergence times were estimated and ancestral distribution areas reconstructed. The monophyly of Triglochin is confirmed and relationships between the major lineages of the genus were resolved. A clade comprising the Mediterranean/African T. bulbosa complex and the American T. scilloides (= Lilaea s.) is sister to the rest of the genus which contains two main clades. In the first, the widespread T. striata is sister to a clade comprising annual Triglochin species from Australia. The second clade comprises T. palustris as sister to the T. maritima complex, of which the latter is further divided into a Eurasian and an American subclade. Diversification in Triglochin began in the Miocene or Oligocene, and most disjunctions in Triglochin were dated to the Miocene. Taxonomic diversity in some clades is strongly linked to habitat shifts and can not be observed in old but ecologically invariable lineages such as the non-monophyletic T. maritima.rnrnChapter 3 is a collaborative revision of the Triglochin bulbosa complex, a monophyletic group from the Mediterranean region and Africa. One new species, Triglochin buchenaui, and two new subspecies, T. bulbosa subsp. calcicola and subsp. quarcicola, from South Africa were described. Furthermore, two taxa were elevated to species rank and two reinstated. Altogether, seven species and four subspecies are recognised. An identification key, detailed descriptions and accounts of the ecology and distribution of the taxa are provided. An IUCN conservation status is proposed for each taxon.rnrnChapter 4 deals with the monotypic Tetroncium from southern South America. Tetroncium magellanicum is the only dioecious species in the family. The taxonomic history of the species is described, type material is traced, and a lectotype for the name is designated. Based on an extensive study of herbarium specimens and literature, a detailed description of the species and notes on its ecology and conservation status are provided. A detailed map showing the known distribution area of T. magellanicum is presented. rnrnIn Chapter 5, the flower structure of the rare Australian endemic Maundia triglochinoides (Maundiaceae, see Chapter 1) was studied in a collaborative project. As the morphology of Maundia is poorly known and some characters were described differently in the literature, inflorescences, flowers and fruits were studied using serial mictrotome sections and scanning electron microscopy. The phylogenetic placement, affinities to other taxa, and the evolution of certain characters are discussed. As Maundia exhibits a mosaic of characters of other families of tepaloid core Alismatales, its segregation as a separate family seems plausible.

On nomenclature and identity of Scarabaeus aeruginosus Linnaeus, S. aeruginosus Drury and S. speciosissimus Scopoli (Coleoptera: Scarabaeoidea: Cetoniinae and Rutelinae)

The valid name for the largest European species of Cetoniinae is Protaetia speciosissima (Scopoli, 1786), with Protaetia aeruginosa (Medvedev, 1964) as a junior synonym. The specimen illustrated by Scopoli in the original description is designated as the lectotype of Scarabaeus speciosissimus Scopoli, 1786. Since the lectotype is lost, a neotype from Piedmont, Italy, is designated and deposited in the Museo Civico di Storia Naturale Carmagnola, Italy. The name Scarabaeus aeruginosus Drury, 1773 is unavailable since Drury did not describe a new species but misidentified Scarabaeus aeruginosus Linné, 1767. A specimen figured by Gronovius in 1764 and cited by Linné is designated as the lectotype of Scarabaeus aeruginosus Linné, 1767. This species remains dubious, but it can be assigned to the ruteline subtribe Anticheirina.
