Epipleoneura fuscaenea Williamson, 1915

(Fig. 18)

Epipleoneura fuscaenea Williamson 1915: 627 –629, plate 44, figs. 29–30 (new species, male description, illustration of S10 lateral and dorsal view, Type material at NMNH). Kennedy 1917: 294, plate xxiii fig. 30–31 (illustration of genital ligula in lateral and ectal view). Rácenis 1960: 25–26 (included in list of species, recorded for British Guyana). De Marmels 1985: 88–89, figs. 1–2 (new record for Venezuela, description of epiproct, illustrations of S 10 in postero-dorsal and oblique-posterior view). Garrison et al. 2010: 352–354, fig. 2342 (included in list of species, illustrations of epiproct in posterior view). Von Ellenrieder 2011: 59, 73 (record from Suriname).

Diagnosis. Epipleoneura fuscaenea is easily distinguished from other species by the presence of a dorso-ventrally flattened cercus dorsal branch with an apical hook (Fig. 18) and the characteristic epiproct (Fig. 18 b–c) with two long and narrow divergent branches, similar only to that of E. metallica, from which it differs by cercus morphology. Other species with dorso-ventrally flattened cercus dorsal branch (i.e. E. angeloi, E. solitaria De Marmels, 1989) lack the apical hook. The apex of segment 3 of genital ligula has two triangular lobes separated by a V cleft; the postero-lateral projection is directed posteriorly with conspicuous peduncle and the apex approximately triangular. Female unknown.

Distribution. Wismar, Guyana (type locality). Culebra, Amazonas State, Venezuela (03°33'N, 65°50'W). Brokopondo, Gansee, Suriname (Garrison et al. 2010); Kwamalasamutu, Sipaliwini, Suriname (von Ellenrieder 2011).

Notes. During my brief visit to the MIZA collection in 2009, I examined material of E. fuscaenea in order to conduct a phylogenetic analysis; unfortunately, I did not draw the studied specimens but only did a schematic drawing of the genital ligula.
