Ocyptamus concinnus  . Thompson et al., 1976: 15 (catalog citation).

As in P. dracula  except: Male. Wing bare on most of posterior ½ of cell bm and anterior margin of cu p. Genitalia: Surstylus setulae shorter. Basiphallus with posterior apex long and gently curved posteriorly; distiphallus with anterior surface strongly curved posteriorly. Postgonite ventro-apical extremity more rounded. Female. Second tergite rectangular and long, length ~ 1.5 times minimum width. Genitalia: 7 th tergite with some pile on apical ½, apical margin slightly concave. Eighth tergite with short extensions at the dorsal start of the basal crest, densely pilose (unusual for Pelecinobaccha  ).

Length. 9–11mm; wing 7–8.5mm.

Distribution. Guatemala, Mexico (Chiapas, Guerrero).
