Baccha concinna Williston, 1891 View in CoL — Williston, 1891: 38. Type locality: Mexico, Guerrero, Chilpancingo. Type female BMNH (not examined).

Ocyptamus concinnus View in CoL . 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: 7th 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 View in CoL ).

Length. 9–11mm; wing 7–8.5mm.

Distribution. Guatemala, Mexico (Chiapas, Guerrero).

Material examined. GUATEMALA. Purchased from Fritz Plaumann by Paul H. Arnaud, Jr., Collection of Paul Arnaud Jr. [green label] April 1966 (1 ♂, USNM ENT 00257738). MEXICO. Chiapas, 20–25 Mi NE Huixtla, 3000 ft., 0 1 Jun 1969, H.J.Teskey (1 ♀, CNC Diptera 161220); ..., 25Mi N Huixtla, 3200 ft., Malaise trap, 4 Jun 1969 (1 ♂, CNC Diptera 161219); …, Finca Prusia (33Km S.

Comments. Nigel Wyatt studied the type specimens in the BMNH, confirming the wing microtrichosity difference between B. concinna and B. dracula .
