( Figs. 6 , 34 , 64 )

Epipleoneura fernandezi Rácenis 1960: 28 –32, figs. 1a–c (new species, description of male and female, illustration of S 10 in posterior and lateral view, female prothorax and mesostigmal lamina in dorsal view, type material at MIZA). De Marmels 1992: 20 (record for Amazonas State). Garrison et al. 2010: 352 –354, fig. 2341 (included in list of species, illustrations of epiproct in posterior view).

Specimens examined. 9♂, 1♀. 6 ♂, Venezuela, Bolivar State, San Francisco de las Babas, río Caroní (Caroni river: 08º09’77”S, 62º48’13”W), 7–13 iv 1983. 2 ♂, campamento base, río Baría, Amazonas State, 3–4 iii 1984. 1♂, Jabillal, Bolivar (10º15’35”S, 67º07’43”W), leg. J. De Marmels, 6–11 viii 1987. PP.

Diagnosis. Male cercus ( Fig. 6 ) resembles that of E. capilliformis . The cercus inner-basal branch is directed medially, with its apex reaching midline of S10 medially and bent posteriorly ( Fig. 6 b). The genital ligula ( Fig. 34 ) is similar to that of E. capilliformis and related species. E. fernandezi differs from other species by unique epiproct morphology, with distal margin with two short lateral branches and a medio-dorsal elevated area extending towards epiproct distal margin as a small medial lobe. The epiproct is similar to those of E. capilliformis and E. demarmelsi , but differs by more pronounced development of lateral branches. The female posterior margin of pronotum ( Fig. 64 ) possesses a medial horseshoe-shaped projection directed posteriorly, and is similar to that of E. venezuelensis ( Fig. 59 ), but with an narrower horseshoe-shaped projection in the latter species. Males of these species are clearly different.

Distribution. Eastern and southern Venezuela in the States of Bolivar and Amazonas (type locality Bolívar State, Canaima, Venezuela, 06°14'N, 62°51'W).
