Coniceromyia diaphaniptera , sp. nov.

(Figs. 3, 14–17, 32–34)

Diagnosis. Foretibia with one anterodorsal and one posterodorsal short strong seta near an obtuse dorsal spine.

Material examined. Holotype 3, BRAZIL: Minas Gerais: Cabo Verde (Fazenda da Cata), 21º 27’ 11” S 46º 20’ 52” W, 16–19.vi.2007, Amorim, Oliveira & Capellari col., Moericke trap, 598 m. Paratype same locality as holotype, 3, 23.ix–15.x.2006, Amorim, Oliveira & Capelari col., Moericke, 598 m.

Description. Male. Body length, 2.0–2.5 mm. Head. Frons light brown, with two dark lines parallel to median furrow, extending from supra-antennals and forming a circle around upper interfrontal bristles; pubescent, with weak median furrow. Flagellomere 1 dark yellow, pubescent, elongate-conical. Arista apical, pubescent. Palpus white; one medium size postocullar seta and one small malar seta. Thorax. Scutum and thoracic pleura yellowish-brown, pair of dark spots lateral of scutellum; anepisternum bare; scutellum dark brown. Legs yellowish-brown; hind femur maculated at apex. Dorsal face of foreleg with one obtuse sinuous spine and an excavation with various strong short setae; a row of nine differentiated setae anterodorsally on apical half, outlining the excavation; one strong short seta anterodorsal and one posterodorsal, near the spine ( Figs. 32–34 ). Foretarsomere 1 with anteroapical process and anterior excavation, without long setae. Hind femur with tiny, blunt posteroventral setae on basal half. Hind tibia with two dorsal setae. Wing. (Fig. 3) Apical third of wing with light maculation, extending from the anterior margin to CuA1. Costa thick, thinner in apical part, 0.39 of wing length; M1 slightly concave along its length, sinuous distally; M2 slightly concave along length, slightly curved anteriorly at apex; distance between M2 and CuA1 at apex of CuA1 about 1.5 times the distance between M1 and M2 at same level; CuA1 gently curved posteriorly on distal half. Base of Rs with two setae; one axilar seta. Halter white. Abdomen. Tergite 1 yellow, tergites 2–6 dark brown, lighter medially and on posterior margin. Abdomen gray ventrally. Terminalia light brown ( Figs. 14–17 ). Epandrial microtrichia extending as in C. franciscana ( Fig. 18 ). Hypoproct with two long setae. Large epandrial setae restricted to laterals. Epandrial dorsal suture present, left suture directed proximally. Proximal part of left epandrial process without long setae, distal part with a short, medially directed lobe bearing six large setae; six setae on right epandrial projection; right subepandrial plate bare; left epandrial process with a ventral lobe; two distinct left subepandrial processes: a distal hairy process not emarginated (lsp1) and an upper dented process (lsp2), very different from C. franciscana ; about 18 subepandrial large setae (sls), one large seta isolated distally.

Female. Unknown.

Etymology. The species name is feminine, and comes from the Greek, meaning “translucid wing”.

Comments. Coniceromyia diaphaniptera and C. anacleti are the only species with a reduced number of dorsal setae in the male foretibia, with an additional obtuse dorsal spine. As commented ahead, these apomorphies suggest that these species compose a small clade within the genus. This species runs into couplet 10 of Kung & Brown’s (2000) key for Coniceromyia species with patterned wing. C. diaphaniptera has no emargination in the wing margin, as also happens in C. maculipennis Borgmeier , but differently from this species, in C. diaphaniptera the wing maculation is very light.
