Epipleoneura pereirai Machado, 1964

( Figs. 7 , 49 , 61 )

Epipleoneura pereirai Machado 1964: 2 –9, figs. 1–3 (new species, description of male and female, illustration of male S 10 in dorsal, lateral and posterior view, pterothorax in lateral view and genital ligula in ectal and lateral view, type material at MIZA). Lencioni 2005: 181, figs. 111 a–c (references, type locality, distribution, described stages, reproduction of original illustrations of male S 10 in lateral and posterior view and female prothorax in dorsal view). Garrison et al. 2010: 352, 355, fig. 2351 (included in list of species, illustrations of epiproct in posterior view). Von Ellenrieder 2011: 58, 61, 74 Fig. 2 (included in list of species of Kwamalasamutu Region, new record for Suriname). Pessacq et al. 2012: 5 (included in list of Brazilian Protoneuridae , new record for Pará State).

Specimens examined. 1 ♂, 1 ♀. 1 paratype ♂, Brazil, Amapá State, Serra do Navio (00º54’03”S, 52º00’14”W), Igarapé Água Fria, leg. A.B.M. Machado & P. Pereira, i 1957. 1 paratype ♀, same data but Tirios, leg. A.B.M. Machado & P. Pereira, i 1963.

Diagnosis. Male cercus ( Fig. 7 ) resembles that of many other species in the genus and is described under E. capilliformis . The cercus inner-basal branch is present, but poorly developed. The epiproct ( Figs.7 b–c) has two unusually long and acute branches widely separated at their bases and slightly convergent, that together with the genital ligula morphology differentiates this species from any other. The genital ligula is very similar to that of E. ocuene (see under that species), but in E. pereirai the postero-lateral projection is widely rounded. The female posterior margin of pronotum ( Fig. 61 ) has a medial long and acute lobe directed posteriorly and two short wide lobes at the sides, similar to those of E. venezuelensis and E. fernandezi , but the medial lobe is rounded in these species.

Distribution. Northern Brazil in the States of Amapá and Pará (type locality, Amapá, Serra do Navio, Macapá County, about 0º52’01”N, 52º01’28”W).

Notes. In the original description for both female allotype and one female paratype the locality is given as ‘a small stream tributary of “alto rio Paru de Oeste” collected in January of 1963 and deposited in MNRJ; however, the information on the label of the paratype female specimen studied in the MNRJ does not agree with that (see under specimens examined above), I contacted Prof. Machado, who confirmed that the correct type locality is the one given in his paper ( Machado 1964), and that the addition of Tiryos (located in Pará State) was actually a mistake.
