Thraulodes Ulmer 1920 (Ephemeroptera: Leptophlebiidae) from Esprito Santo state, Brazil.

Based on material collected during the past 10 years in the State of Esprito Santo and adjacent areas in Minas Gerais, Southeastern Brazil, we identified three species of the genus Thraulodes: T. itatiajanus Traver Edmunds, for which we present new records and description of the female imago; T. luisae Souto, Da-Silva Nessimian, first recorded for the state and for which we describe the nymphal stage; and T.

A new species in Simulium (Trichodagmia) (Diptera: Simuliidae) from Chapada Diamantina region, Brazil: cryptic diversity revealed by morphological and molecular evidence.

We describe new species of black fly that had previously been identified as S. scutistriatum Lutz due to morphological similarities at the pupal stage. The description of the new species, Simulium (Trichogamia) itajara n.

Redescription of adults of Simulium jeteri (Py-Daniel, Darwich, Mardini, Strieder amp; Coscarón, 2005) (Diptera: Simuliidae).

Simulium jeteri (Py-Daniel, Darwich, Mardini, Strieder Coscarón, 2005) was not fully described, because only pharate male and female adults extracted from pupae were used for the original descriptions. Important diagnostic characters were either incompletely or poorly described. During field work in areas at the same hydrographic basin of the type-locality, we were able to rear adult stages.

Morphology and Polytene Chromosomes of a New Species of Simulium (Trichodagmia) (Diptera: Simuliidae) from the Espinhaço Mountains of Brazil.

The species richness of black flies in the Simulium (Trichodagmia) orbitale (Diptera: Simuliidae) species group is greatest in southern Brazil, where 9 of 19 species are found. A new species in the S. orbitale group was collected during a survey of black flies in Minas Gerais state, Brazil, in the Espinhaço Mountains, an area rich in endemic taxa.
