( Figs. 17 , 51 )

Epipleoneura solitaria De Marmels 1989: 21 –22, 63, figs. 59–63 (new species, description of male, illustration of male S 10 in dorsal, lateral and posterior view, genital ligula in ectal and lateral view, synthorax in lateral view, type material at MIZA). Garrison et al. 2010: 352, 354, figs. 2328–2329, 2335 (included in list of species, illustrations of S 10 in latero-posterior, lateral and posterior view).

Diagnosis. The cercus, epiproct and genital ligula of this species are unique within the genus. The cercus ( Fig. 17 ) is shorter than S10, without inner-basal branch or tooth, and the dorsal branch is directed dorsally, flattened and its inner surface concave, without apical hook; the ventral branch is small and also flattened dorso-ventrally. The epiproct ( Fig. 17 b–c) is long, with two relatively thick branches separated by a small distance and joined at their bases. The apex of segment 3 of genital ligula ( Fig. 51 ) has a rounded lobe on each side and a shallow V medial cleft. The postero-lateral projections are directed laterally and have the peduncle well developed. The epiproct of E. manauensis is similar to that of E. solitaria , but cercus and genital ligula are clearly different. Female unknown.

Distribution. Southern Venezuela, Amazonas State (type locality, Amazonas State, Río Negro, Canal Ocuene , Río Baría, about 1º20’N, 66º28’W).
