Provedor de dados: 82
Autores: Pessacq,P.
Specimens of Dactylophlebia carnulenta Pescador &amp;amp; Peters, only known from nymphal stage, were collected and reared in situ. From the material obtained, Archethraulodes spatulus Pescador &amp;amp; Peters, known from male imago and the only known species for the genus, is proposed as junior synonymy with D. carnulenta. Additionally, female imago and subimagos of D. carnulenta are described.

Based on collections in five municipalities from southern Bahia, a new species, Paracloeodes quadridentatus sp. n., is described from Brazil. It can be distinguished, among other characteristics, by the presence of three, often four, well developed denticles on the tarsal claws, a characteristic that has never been found in other species of the genus. Besides the description of the new species, the following 14 taxa of Baetidae are recorded for the first time from the State of Bahia: Americabaetis alphus Lugo-Ortiz &amp;amp; McCafferty, Americabaetis labiosus Lugo-Ortiz &amp;amp; McCafferty, Aturbina georgei Lugo-Ortiz &amp;amp; McCafferty, Baetodes sp., Callibaetis sp., Camelobaetidius francischettii Salles Andrade &amp;amp; Da-Silva, Camelobaetidius...

Intersexuality in Farrodes Peters, 1971 (Ephemeroptera: Leptophlebiidae: Atalophlebiinae) from Brazil
Provedor de dados: 92
Autores: Santos,Rodrigo Pires; Moreto,Viviana; Mariano,Rodolfo.
ABSTRACT Gynandromorphism or intersexuality is a rare condition where the individual has male and female features. In this report we described two imagoes of Farrodes xingu Domínguez et al. (1996) from Brazil presenting intersex traits. We considered the arranged sexual characters as antero-posterior and bilateral. One individual has a male head, abdomen full of eggs and the subgenital plate with a malformed outset of penes (antero-posterior), while the other individual has half of the head with a male-like turbinate eye and the other half with a regular female-like one, and with malformed male genitalia (bilateral).

First report of Simuliidae and Chironomidae (Diptera) living on nymphs of Lachlania Hagen (Ephemeroptera: Oligoneuriidae) in South America
Provedor de dados: 49
Autores: Pepinelli,Mateus; Siqueira,Tadeu; Salles,Frederico Falcão; Shimbori,Eduardo Mitio.
We report cases of Simuliidae and Chironomidae living on Lachlania nymphs (Ephemeroptera). This is the first record of these associations in South America. Simulium exiguum (pupae and larvae), Simulium cuasiexiguum (larvae), Cricotopus sp. (larva) and Rheotanytarsus sp. (larva) were found associated with Lachlania nymphs. We believe that all of these associations can be classified as opportunistic (or casual) attachment.
