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.

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.
