( Figs. 127–130 View FIGURES 127 – 130 , 187 View FIGURES 174 – 190 , 240 View FIGURES 239 – 243 , 312 View FIGURES 312 – 317 )

Diagnosis (male). Wing apex with antero-posterior fold and a dorsal group of long microtrichia.

Material examined. Holotype ♂, BRAZIL: São Paulo: Sertãozinho, Reserva Biológica Augusto Ruschi , Malaise trap, 24.xi –08.xii.2010, B. Brown col. ( MZSP).  

Description. Male. Body length, 1.8 mm. Head. Frons black, sparsely setulose, with well-defined median furrow. Flagellomere 1 yellowish-brown, pubescent, elongate-conical. Arista apical, pubescent, about as long as flagellomere 1. Palpus yellowish-brown; two genal setae. Thorax. Scutum, scutellum and pleural regions brown, anepisternum bare. Legs yellowish-brown, except hind femur brown. Forefemur with two ventral rows of thin setae. Foretibia with two dorsal setae and anterodorsal row of strong setulae. Foremetatarsus with anteroapical setulose process, anterior excavation, long basal setae, seta at base of anteroapical process, and dorsal strong setula ( Fig. 187 View FIGURES 174 – 190 ). Hind femur swollen (height/length ratio, 0.45), with posteroventral group of tiny blunt setulae with semicircular distribution, tapering toward ventral margin—dorsal setulae thicker ( Figs. 312 View FIGURES 312 – 317 ). Hind tibia with one dorsal seta. Wing ( Fig. 240 View FIGURES 239 – 243 ). Costa not swollen, short, about a third of the wing length; M1 almost straight; M2 slightly sinuous, antero-posterior distance between M2 and CuA1 at CuA1 apex about the same distance between M1 and M2 at the same level; CuA1 concave, with posterior curvature at apex. Fold and dorsal group of long microtrichia near apex of wing. Halter gray, with an apical white circle. Abdomen. Tergites dark brown, with lighter posterior band. Hypopygium yellowish-brown ( Figs. 127–130 View FIGURES 127 – 130 ). Epandrium covered with microtrichia mostly dorsally, small proximal lateral areas bare; dorsal suture of the epandrium present, left suture not evident. Left epandrial process dorsally setose, medially concave, with apical setulose projection medially directed and a subepandrial setulose elevation. Right epandrial projection with subepandrial group of setulae. Hypoproct with two setae. Hypandrium without projections.

Geographical distribution. Known only from the type-locality, in an area with semideciduous forest in the State of São Paulo, Brazil.  

Comments. This species shares some distinctive features with Coniceromyia basalis   , as the short costa, a similar foreleg setation and the hind femur swollen. The hypopygium of C. tanycrossa   , however, presents a characteristic left epandrial process concave medially and with a subepandrial setose elevation, differently than C. basalis   .

Etymology. The specific epithet tanycrossa   is derived from the Greek roots tanyo (stretch out, long) and krossos (fringe), referring to the dorsal group of long microtrichia close to the apex of the wing.
