Six new species of Paraleia Tonnoir (Diptera, Mycetophilidae): amphinotic elements at the northern range of the Andes

Paraleia was originally described by Tonnoir for P. fulvescens, known from Australia. More recently, eleven Neotropical species were added to the genus-nine of which are from Chile and southern Argentina, one from Bolivia, and one from Peru. This distribution pattern is typical of many mycetophilid genera. Six new Neotropical species of Paraleia from the Andean Colombia and Ecuador are herein described. Male terminalia of P. bolivari sp. n., P. denticulata sp. n., P. fumosa sp. n., and P. tonnoiri sp. n., as well as female terminalia of P. bolivari sp. n., P. denticulata sp. n., P. fumosa sp. n., P. nidorosa sp. n., P. sharkeyi sp. n., and Paraleia sp. are illustrated. High-resolution photos of wings for all species are presented. An identification key for world species of Paraleia is provided.

Description of Rhodnius montenegrensis n. sp (Hemiptera: Reduviidae: Triatominae) from the state of Rondonia, Brazil

We present here a multisource approach that takes advantage of several disciplines to address a taxonomic issue. A triatomine related to Rhodnius robustus Larrousse, 1927 was recently found in the state of Rondonia, Brazil. The name Rhodnius montenegrensis n. sp. is suggested because it was found in the municipality of Monte Negro. The main differences between these two species can be detected in the female and male genitalia, but there are also noticeable differences in their eggs. Molecular analysis using PCR-RFLP technique and Bayesian inferences based on a fragment of the Cytochrome b (Cyt b) gene corroborated the morphological findings. We used this integrative approach to address the taxonomic decision for a new Rhodnius species and its relationship with others of this genus. Results obtained herein stress that morphology must be used as the major approach for obtaining phenotypic information, and molecular data should be taken as a complementary tool.

New genera and species of Neotropical Rhinotragini (Coleoptera, Cerambycidae, Cerambycinae)

Giesberteclipta and Thomasella, two new genera of Rhinotragini Thomson, 1861 (Coleoptera: Cerambycidae: Cerambycinae), are described and illustrated. Six new species are also described and illustrated: Acyphoderes violaceus from Costa Rica; Ischasioides giesberti from Ecuador, and Oxylymma pallida, Pseudagaone williamsi, Stultutragus tippmanni and S. ventriguttatus from Brazil.

On the taxonomic status of Chactas camposi Mello-Leitao, 1939 (Scorpiones, Chactidae)

The true taxonomic status of the chactid scorpion Chactas camposi Mello-Leitao, 1939 from Ecuador is established based in the recently discovered holotype female, until now considered lost, at the Museu Nacional do Rio de Janeiro. In base on the analysis of the external morphology, we transfer this species to the genus Teuthraustes Simon, 1878. A detailed redescription and diagnosis according to modern standards are provided. Teuthraustes camposi comb. n. is closely related with Teuthraustes whymperi (Pocock, 1893) from Ecuadorian provinces Pichincha and Cotopaxi.

Description of the female and new records of Triatoma baratai Carcavallo & Jurberg, 2000 (Hemiptera: Heteroptera: Reduviidae: Triatominae) from Mato Grosso do Sul, Brazil, with a key to the species of the Triatoma matogrossensis subcomplex

Triatoma baratai Carcavallo & Jurberg, 2000, a species similar to Triatoma williami Galvao, Souza & Lima, 1967 and belonging to the T. matogrossensis subcomplex, was described based on a male specimen collected in a sylvatic environment, near a cave, in Bonito county, Bodoquena mountain range, state of Mato Grosso do Sul, Brazil. In the present work we describe the female of T. baratai, captured in a chicken house, in Nioaque county, state of Mato Grosso do Sul, Brazil. Furthermore, we recorded the occurrence of T. baratai in domiciles and peridomestic environment in another four municipalities (Bodoquena, Bela Vista, Corumba, and Miranda), extending its geographical distribution. Finally, we present a key to the species of the Triatoma matogrossensis subcomplex.

New species of Fissiphallius Martens 1988 from Brazil and notes on the morphology of Fissiphalliidae (Arachnida, Opiliones)

The seventh species of Fissiphallidae, Fissiphallius orube sp. nov., and the fourth from Brazil (type locality state of Acre, Cruzeiro do Sul, at the Moa river), is described.

New species of Pseudanos Winterbottom, 1980 (Characiformes: Anostomidae), with notes on the taxonomy of P. gracilis and P. trimaculatus

A new species of Pseudanos (Characiformes, Anostomidae) is described from the Rio Negro in Brazil, and the Rio Casiquiare and Rio Atabapo, in Venezuela. Specimens of the new species were previously mistakenly identified as Pseudanos gracilis. The new species is diagnosed by having three branchiostegal rays (vs. four in P. gracilis and most specimens of P. winterbottomi), dark transversal bars on dorsum absent (vs. present in P. trimaculatus), dark spots present on the center of each body scale, forming conspicuous, straight dark lines (vs. dark spots absent in P. gracilis and in some specimens of P. trimaculatus), four midlateral dark blotches on body (vs. usually two, sometimes three or four in P. trimaculatus, or body lacking midlateral blotches and presenting instead a broad midlateral stripe in P. winterbottomi), angle of dorsal and ventralmost radii of body scales between 40 degrees and 90 degrees (vs. angle between 110 degrees and 180 degrees in P. gracilis and P. trimaculatus), and cranial fontanel opened along its entire length (vs. cranial fontanel partially closed in P. trimaculatus). Type specimens and extensive additional material of Pseudanos gracilis and P. trimaculatus were examined and comments on the taxonomy of both species are provided. Pseudanos irinae is herein considered a junior synonym of P. trimaculatus. In addition, an updated key to identification of valid species of Pseudanos is presented.
