Pelecinobaccha Shannon, 1927: 10  , as a subgenus of Baccha  . Type species: Baccha peruviana Shannon, 1927  (original designation). Miranda et al. (2014) proposed it as a genus.

Baccha tristis  species group, in part. Hull (1949a).

Ocyptamus tristis  species group, in part. Mengual et al. (2012).

Diagnosis. Dorsal occiput with two rows of pile (rarely anterior row with very short pile). Wings usually with dark markings. Petiolate abdomen, but might be very narrow and long. Female sixth segment modified into a single conical sclerite.

Biology. Very little is known about the natural history of Pelecinobaccha  , despite the large number of species. Larval biology is only known for records of P. costata ( Say, 1829)  and P. squamagula  Miranda in Miranda et al., 2014, whose immatures feed on scale insects ( Hemiptera  : Coccidae  ) ( Rojo et al. 2003; Miranda et al. 2014).

Comments. Many of the Pelecinobaccha  species have a bicolored metatarsus, the metabasitarsomere having a dark base and pale apex. This genus is unique in having distinctly modified female genitalia, which is believed to be related to the placement of their eggs under the scale of their larval prey, Coccidae  ( Hemiptera  ) ( Miranda et al. 2014). Miranda et al. (2014) distinguished four species groups: 1) P. adspersa  species group (flies with polished black head and wholly dark metatarsus); 2) P. brevipennis  species group (very slender flies similar to the Ocyptamus stenogaster  species group, with long abdomens, and maculae on tergum 3 restricted to a lateromedial pair); 3) P. peruviana  species group (typical Pelecinobaccha  with bicolored metabasitarsomere, with basal half or more dark); and 4) P. summa  species group [as P. susio  species group; see Miranda 2017] (only group with scutum pale laterally, at least on notopleuron and postalar callus, and with distinct pale microtrichose vittae, and metabasitarsomere usually with less than basal half dark).
