Moved
Moved from Subgenus Pachyconops.

Keys clearly to P. bulbirostris in Camras (1955). Significant characters include:

    Frons entirely black; Cheeks darker than face, black or brownish;
    Body dark overall; Mesopleuron without pollinose stripe; Theca very long;
    Basal radial cell br and base of discal medial cell dm hyaline for at least one half;
      Submarginal cell paler apically.

Photos here agree well with Williston's description of the synonym Conops sequax at the botton of the page here, and with the figures in Stuke & Skevington (2007) [PDF here]...in particular the wing infuscation pattern shown in Fig. 73, the theca size/shape in Fig. 72, and the coloration of frons and body in Fig. 70.

Moved
Moved from Physoconops.

This is Physoconops
Moved from Physocephala.

Position of crossvein r-m vis-a-vis discal cell; swelling at base of antennae; very long third antennal segment+style, very large theca...indicate this is a female in the genus Physoconops...see here for more details.
