Coniceromyia piricornis Borgmeier, 1950: 292   , textfig. 5, 16, plate xviii, fig. 2.

Diagnosis (male). Foretibia and foretarsus spirally curved; M1 almost entirely straight, M2 straight at basal half.

Material examined. Holotype ♂, BRAZIL: Mato Grosso: Salobra , viii.1939, Expedição C.Z.B. ( MZSP).  

Redescription. Male. Body length, 1.7 mm. Head. Frons dark brown, sparsely setulose, with well-defined median furrow. Flagellomere 1 light brown, apical half darker, pubescent, conical. Arista apical, pubescent, about twice the length of flagellomere 1. Palpus yellowish-brown; two genal setae. Thorax. Scutum, scutellum and pleural regions brown; anepisternum bare. Legs yellowish-brown. Foretibia and foretarsus spirally curved.

Foretibia with two dorsal setae and anterodorsal row of strong setulae. Foremetatarsus with anteroapical setulose process, anterior excavation and long basal seta ( Fig. 179 View FIGURES 174 – 190 ). Hind femur not swollen (height/length ratio, 0.36), with narrow posteroventral group of tiny blunt setulae adjacent to ventral margin ( Figs. 298–299 View FIGURES 298 – 304 ). Hind tibia with one dorsal seta. Wing ( Fig. 231 View FIGURES 227 – 238 ). Costa swollen, 0.4 of the wing length; M1 almost straight, curved anteriorly at apex; M2 parallel to M1 on basal half, sinuous on distal half; antero-posterior distance between M2 and CuA1 at CuA1 apex about the same distance between M1 and M2 at the same level; CuA1 with two concavities. Group of dense microtrichia ventrally on the wing, posterior to M2. Halter brown. Abdomen. Tergites dark brown, with lighter posterior band. Hypopygium brown ( Figs. 113–115 View FIGURES 113 – 115 ). Epandrium covered with microtrichia mostly dorsally, proximal lateral areas bare; dorsal and left lateral sutures could not be observed. Left epandrial process setose on apical half, with setulose medially directed process near hypoproct. Right epandrial projection with subepandrial group of setulae. Hypoproct setae could not be observed. Hypandrium without projections.

Geographical distribution. Known only from the type-locality in southwestern Brazil, in the State of Mato Grosso.  

Comments. The hypopygium description and the recognition of the foretibia anterodorsal row of strong setulae, the excavation of the foremetatarsus, and the seta at the base of the anteroapical process are the main additions to the original description of C. piricornis   . Coniceromyia piricornis   seems to be closely related to C. valdesi   , sharing with this species a nearly identical hypopygium and group of microtrichia ventrally on the wing posteriorly to M2 (very subtle in C. piricornis   ).
