Type species: Baccha fascipennis Wiedemann, 1830

Ocyptamus fascipennis species group. Mengual et al. (2018)

Description. Head . Face narrow (between 1/4 and 1/3 of head width) and either pale or mostly dark (Fig. 84); tubercle on ventral 1/2 of the face (Fig. 84). Frons ~1/3 of head width. Antennal insertions confluent (Fig. 84). Female ocellar triangle ~1 ocellus-width from lateral eye margin. Dorsal occiput with 1 row of pile (Fig. 85). Thorax. Scutum dark, and with anterior row of longer pile (’collar’ of authors, see Fig. 49 in Mengual et al. 2018). Scutellum mostly pale but darker laterally. Anterior anepisternum pilose. Katatergite with long microtrichia (as in Fig. 62). Metaepisternum pilose. Metasternum bare. Upper calypter margin with pile shorter than pile on the ventral calypter margin. Male metafemur with longer pile on anterior surface. Wing. *Alula mostly bare except for apical 1/4. Wing hyaline with a median dark triangular marking (Fig. 12); *most of cells c, br and bm bare. Abdomen. Abdomen elongated, narrow, and slightly petiolate (Fig. 12); terga with either quadrangular or triangular pale maculae baso-laterally (Fig. 12). Terminalia. Female tergum 7 rectangular and wide; tergum 8 rectangular, wide and with distinct concavity on posterior margin (Fig. 14); *epiproct as a pair of sclerites connected by a basal narrow bridge, and sclerites fuse into cerci apico-laterally by a narrow strip (Fig. 14). *Male subepandrial sclerite quadrangular, with baso-lateral corners extended basally and similar to ‘horns’ (Fig. 13); basiphallus teardrop-shaped, distiphallus membranous with dorsal sclerotized triangular region.

Included species (2): H. fascipennis (Wiedemann, 1830) comb. nov. [3, 4], H. lemur (Osten Sacken, 1877) comb. nov. [3, 4].

Etymology. The name is a reference to the Latin word ‘ hypocrites ’ which relates to ‘actor’ or ‘mime’, an allusion to the fact that this group resembles, ‘pretends to be’, Ocyptamus, but is not that genus. The name is to be treated as masculine.

Comments. This Nearctic genus, corresponding to the former Ocyptamus fascipennis species group, is characterized by distinctive wing markings (Fig. 12) and the medial swelling on the 2nd abdominal segment (Fig. 12). Some codons in the cytochrome B gene are so far unique to this genus (Miranda et al. 2016). Further information on this group can be found in Mengual et al. (2018).
