Smallish fly, on Soybean ('tis the season), probably around 3-4mm in length. Terrible pictures, and it may be misplaced dots making me think so, but is it a Tephritoid, possibly Ulidiidae? January 2016, in Mpongwe, Copperbelt, Zambia. EDIT: Title updated from 'Tephritoid? Zambia.'

Lauxaniidae? It appears to be a female without an oviscape, so I doubt Tephritoidea. |

I think so (99% sure), Lauxaniid

Certainly NOT a tephritoid; I'd notified its large trapezoid scutellum -- just do not recall right now if any Lauxaniidae Homoneurinae (which this fly could be) have them. It looks very similar to that in some Drosophilidae Steganinae, but your picture show no basal cells clearly. Val |

Lauxaniid would have been my second stab in the dark... Thanks for correction. Have updated title and will revisit if I see more of these around. |

Dredging through: 5-6 Homoneurinae genera in sub-saharan Africa: Cainohomoneura - only one species known (C. delta), Stuckenberg notes that thorax unremarkable (so presumably not trapezoidal scutellum), and wing-patterning not close. Homoneura - which Stuckenberg notes to be a major constituent of African fauna. Katalauxania - Kilimandjaro, wing quite different. Prosopomyia - wing unpatterned. Trypetisoma (Trypaneoides) - seems to be only T. perpunctata, which Stuckenberg reports from mainland. No mention of scutellum in description, wing-pattern unlike it. and Zanjensiella - Madagascar, wings unpatterned. Also, found some more pictures of a very, very similar fly from Mkushi (central province, almost at junction with Kasanka, D.R.C.), and also in Soy (below). Could this possibly be homoneura? Some in previous discussions have appeared structurally similar, albeit never quite identical. |

The head is typical of Lauxaniidae and I see nothing inconsistent with that family. |
