Redescription. Male. Body length, 1.8 –2.0 mm. Head. Frons brown, sparsely setulose, with well-defined median furrow. Flagellomere 1 yellowish-brown, pubescent, elongate-conical. Arista apical, pubescent, short, about one fourth flagellomere 1 length. Palpus yellowish-brown; two genal setae. Thorax. Scutum and pleural regions brown, sometimes with lighter areas at anepisternum and katepimeron; anepisternum bare; scutellum dark brown. Legs yellowish-brown. Foretibia with two dorsal setae and anterodorsal row of strong setulae ( Fig. 147). Foremetatarsus with anteroapical setulose process, anterior excavation, long seta at base of excavation, and seta at base of the anteroapical process. Hind femur swollen (height/length ratio, 0.46), with posteroventral group of tiny blunt setulae with semicircular distribution, tapering toward ventral margin ( Figs. 258). Hind tibia with one dorsal seta. Wing ( Fig. 199). Costa swollen, short, 0.3 of wing length; M 1 almost straight, curved posteriorly at apex; M 2 slightly concave, antero-posterior distance between M 2 and CuA 1 at CuA 1 apex about the same distance between M 1 and M 2 at the same level; CuA 1 sinuous. Halter white. Abdomen. Tergites brown, with lighter posterior band. Hypopygium light brown ( Figs. 31–36). Epandrium covered with microtrichia mostly dorsally, large proximal lateral areas bare; epandrial dorsal and left sutures present. Left epandrial process dorsally setose, with two subepandrial processes: an apical setulose elevation ( Figs. 32 and 34, black arrow) and a curved, medially directed setulose projection ( Figs. 32 and 34, white arrow). Three to eight large subepandrial setae. Right epandrial projection with subepandrial group of setulae. Hypoproct with 2–4 setae. Right lobe of hypandrium with lateral projection.

Geographical distribution. Brazil, State of Santa Catarina, Rio de Janeiro and higher areas in the state of São Paulo.

Comments. The hypopygium description and the recognition of the foretibia anterodorsal row of strong setulae, foremetatarsus excavation and foremetatarsus posterior strong setula are the most important additions to the original description of this species. Coniceromyia basalis is one of the best documented species of the genus, with specimens collected from several localities in southern and southeastern Brazil. This allows the recognition of some variation in relation to the holotype. The specimens from Santa Catarina, Urubici ( Brazil) and one specimen from São Paulo, Ribeirão Grande ( Brazil) have a characteristic tuft of long thin setae on the foretibia ventral apex, while the specimens from São Bento do Sul, in the State of Santa Catarina, have a distinct lighter coloration.
