A new genus, Lupaeus gen. nov., is created to contain part of the described species in the genus Pulaeus Den Heyer. A key to the genera of the tribe Pulaeini, to which these two genera belong, and one auxiliary key to the species of Brazil and South Africa, are provided. Four new species, viz. Pulaeus myrtaceus sp. nov., P. quadrisolenidius sp. nov., Lupaeus lectus sp. nov. and L. lobidorsalis sp. nov. are described and figured. P. martini Den Heyer, 1981 is designated as type species for the new genus. New nomenclatural combinations are reported.

A new cunaxid genus from Brazil, Cunaxatricha gen. nov., is erected and its type species, Cunaxatricha tarsospinosa sp. nov. is described and figured. A key to the genera of the subfamily Cunaxinae, to which this new genus belongs, is provided.

Four new cunaxoidine genera (Acari: Prostigmata: Cunaxidae) and the description of two new Neotropical species

In this paper the genus Cunaxoides Baker & Hoffmann, 1948, as delimited by Den Heyer (1979a, 1981b), is revised and divided into five genera, viz. Cunaxoides Baker & Hoffmann, Bunaxella gen. nov., Dunaxeus gen. nov., Funaxopsis gen. nov. and Qunaxella gen. nov.. Two new Neotropical species, Dunaxoides duosetosus and Qunaxella triasetosa are described and figured. Additional southern African material is reported.

A new genus of Neotropical Chrysopini (Neuroptera: Chrysopidae)

Titanochrysa Sosa & Freitas is a new genus of Neotropical Chrysopini (Chrysopidae: Chrysopinae) recorded from Costa Rica, Venezuela and Brazil. Titanochrysa gen. nov. shares several external and genitalic characters with Ceraeochrysa Adams, 1982; Chrysopodes Navas, 1913; Cryptochrysa Freitas & Penny, 2000; Parachrysopiella Brooks & Barnard, 1990 and Ungla Navas 1914. It may be distinguished from those genera by its very long sternite 8+9, sternites 2-8 usually with microtholi, male genitalia with the dorsal surface of the arcessus striated, gonosaccus well-developed, bearing elongate gonosetae and microsetae, and a spoon-like gonapsis. Herein, Titanochrysa circumfusa (Burmeister, 1939) [= Chrysopodes circumfusa (Burmeister)] comb. nov. and Titanochrysa pseudovaricosa (Penny) [= Ceraeochrysa pseudovaricosa Penny, 1998] comb. nov. were identified; Titanochrysa ferreirai Sosa & Freitas sp. nov. and Titanochrysa trespuntensis Sosa & Freitas sp. nov. were described. The external morphology, and male and female genitalia of all these species are described. Titanochrysa circumfusa (Burmeister, 1939) comb. nov. is recorded for the first time from Venezuela.

A new genus and species of tarsonemid mite (Acari: Tarsonemidae) from Brazil

Biscutulumnemus neotropicus gen. nov., sp. nov. (Tarsonemidae: Tarsoneminae: Tarsonemini) is described from adult female and male mites, collected on Croton floribundus Spreng., from São José do Rio Preto, State of São Paulo, Brazil. This new genus resembles members of Dendmptus and Tarsonemus, but male mites have two triangular shields anterolaterally to the prodorsal shield and the sejugal apodeme is absent. In addition, Biscutulumnemus differs from Dendroptus by the presence of femoral seta l″ and tibial solenidion φ1 and the presence of a vestigial apodeme I on female mites. Unlike Tarsonemus, Biscutulumnemus has a beaklike gnathosomal capsule, a round flange on leg IV of male mites, and stigmata very close to v1 on the prodorsal shield of female mites.

A new cunaxid genus with descriptions of two new species from Brazil (Acari: Prostigmata: Bdelloidea: Cunaxidae)

The genus Pseudobonzia Smiley 1975 is revised and divided into two genera. The genus Pseudobonzia Smiley, 1975, with its type species and five other related species, is retained. The remainder of the group is now known as Coleobonzia gen. nov. of which the main characteristics are provided. Coleobonzia argillae (Den Heyer, 1977) is designated as type species for the new genus. Two species from Brazil, viz. Coleobonzia clava sp. nov. and C. moraesi sp. nov. are described and figured. A key to the two genera as well as a key to the Brazilian and South African species of the new genus are provided. Copyright © 2008 Magnolia Press.

A new genus and species of pterodectine feather mite (Acari: Proctophyllodidae) from Tod-Tyrants in Brazil (Passeriformes: Tyrannidae)

A new genus and species of feather mite, Hemitriccodectes furcatus gen. nov., sp. nov., is described from passerines of the genus Hemitriccus from Brazil: Hemitriccus furcatus, H. margaritaceiventer and H. striaticollis (Tyrannidae). The new genus belongs to the Pterodectes generic complex and most clearly differs from previously established genera of this complex by the following combination of features: trochanteral setae sRIII are present, and solenidia σ are absent from genua III. The new genus also lacks dorsal hysteroromal setae c1. © 2013 Versita Warsaw and Springer-Verlag Wien.

Cryptococcus haglerorum, sp nov., an anamorphic basidiomycetous yeast isolated from nests of the leaf-cutting ant Atta sexdens

A yeast strain (CBS 8902) was isolated from the nest of a leaf-cutting ant and was shown to be related to Cryptococcus humicola. Sequencing of the D1/D2 region of the 26S ribosomal DNA and physiological characterization revealed a separate taxonomic position. A novel species named Cryptococcus haglerorum is proposed to accommodate strain CBS 8902 that assimilates n-hexadecane and several benzene compounds. Physiological characteristics distinguishing the novel species from some other members of the C. humicola complex are presented. The phylogenetic relationship of these strains to species of the genus Trichosporon Behrend is discussed.

Sympodiomyces attinorum sp nov., a yeast species associated with nests of the leaf-cutting ant Atta sexdens

Four strains of a novel yeast species were isolated from laboratory nests of the leaf-cutting ant Atta sexdens in Brazil. Three strains were found in older sponges and one was in a waste deposit in the ant nests. Sequencing of the D1/D2 region of the large-subunit rRNA gene showed that the novel species, named Sympodiomyces attinorum sp. nov., is phylogenetically related to Sympodiomyces parvus. Unlike Sympodiomyces parvus, Sympodiomyces attinorum can ferment glucose, assimilate methyl alpha-D-glucoside, salicin and citrate, and grow at 37 degreesC, thus enabling these two species to be distinguished. Differentiation from other related species is possible on the basis of other growth characteristics. The type strain of Sympodiomyces attinorum is UNESP-S156(T) (=CBS 9734(T)=NRRL Y-27639(T)).

Natural infection of gastrointestinal nematodes in long-nosed armadillos Dasypus novemcinctus Linnaeus, 1758 from Pantanal wetlands, Aquidauana sub-region, Mato Grosso do Sul State, with the description of Hadrostrongylus speciosum n. gen. et n. sp (Molineidae : Anoplostrongylinae)

This study evaluated the gastrointestinal helminth fauna of long-nosed armadillos, Dasypus novemcinctus, from the Pantanal wetlands, Aquidauana sub-region, Aquidauana County, Mato Grosso do Sul State, Brazil. Thirteen species of nematodes, comprising seven genera and four families, were recovered from their gastrointestinal tracts. The following descriptors of infection were determined: prevalence, variation of intensity, average intensity and abundance. Hadrostrongylus speciosum n. gen. et n. sp. is first described here.
