Mesoconius flaviceps – Steyskal 1968: 9 (lapsus).

Diagnosis (based on holotype photo and notes)

Length 17 mm. Most of head, thorax and abdomen black to dark brown; clypeus bright yellow. Ocellar triangle elevated. Legs yellow, except for black-brown basal 4/5 of fore tibia and darkened distal tarsomeres on at least hind leg. Wing strongly infuscated on distal half, with large clear areas in cell r 2+3 and cell r 4+5. Head chaetotaxy unclear, one inner vertical bristle remaining. Katatergite swollen and strongly tuberculate. Abdominal segment 1 petiolate. Terminalia with S8 directed at right angles to preabdomen (typical of M. infestus group), twice as large as epandrium, shiny black. Epandrium reddish brown, subquadrate.

Material examined

Holotype COLOMBIA • ♂; v. Nolcken leg.; MNBG. The collector was presumably J.H. Wilhelm Baron (von) Nolcken, who collected in the mountains of Colombia 1870–71 ( Horn & Kahle 1936).

Remarks

Mesoconius flavipes has previously been diagnosed on the basis of its uniformly orange hind femur. The only specimen available is the holotype, which is impossible to confidently place in a species group. It has the general habitus of an M. infestus group species, including the strongly deflected male terminalia, so it is tentatively included with that group here.
