Coniceromyia franciscana , sp. nov.

(Figs. 4, 18–21, 26–28)

Diagnosis. Male wing maculated on apical third, male foretibia excavated, with two large setae, a large spine, and an anterodorsal seta.

Material examined. Holotype, 3, BRAZIL: Santa Catarina: São Bento do Sul (Cepa Rugendas), 26º 15’ S 49º 23’ W, 13–16.x.2001, Malaise trap, Projeto FAPESP BIOTA-Hymenoptera/Isoptera. Paratype, 3, same but São Francisco do Sul, Vila da Glória, 26º 15’ S 48º 38’ W, Malaise trap, Projeto FAPESP BIOTA- Hymenoptera/Isoptera.

Description. Male. Body length, 2.7–3.0 mm. Head. Frons dark brown, pubescent, with well defined median furrow. Flagellomere 1 dark yellow, pubescent, elongate-conical. Arista apical, pubescent. Palpus white; one medium postocullar setae and one little malar seta. Thorax. Scutum and thoracic pleura yellowishbrown; Anepisternum bare; scutellum dark brown. Legs yellowish-brown. Dorsal face of foretibia with two long setae, one sharp sinuous spine and an excavation with approximately 20 strong tiny setae. Anterodorsal face with a row of four slightly differentiated orange setae on apical third and a tiny, strong seta near the spine ( Figs. 26–28 ). Tarsomere 1 with anteroapical process; no anterior excavation; without long setae. Hind femur with tiny, blunt posteroventral setae on basal half. Hind tibia with two dorsal setae. Wing. (Fig. 4) Apical third of the wing darkly maculated, maculation extending from the anterior margin to CuA1. Costa thick, thinner apically, relatively long, 0.49 of wing length; M1 arched anteriorly at basal third, curved posteriorly at apex; M2 slightly concave along length, slightly curved anteriorly at apex; distance between M2 and CuA1 at apex of CuA1 about 3.5 times the distance between M1 and M2 at same level; CuA1 slightly curved posteriorly on distal fourth. Rs base with two setae; one axilar seta. Halter white. Abdomen. Tergites dark brown, with white posterior margin. Tergite 2 and 6 longer than other tergites. Abdomen gray ventrally. Terminalia light brown ( Figs. 18–21 ). Hypoproct without long setae. Epandrial microtrichia not extending through latero-proximal portions. Large epandrial setae restricted to the laterals. Epandrial dorsal suture present, left suture directed proximally. Seven setae on right epandrial projection. Proximal part of left epandrial process with approximately seven long setae, distal part ending in a medially directed lobe, with an apical tooth. Right subepandrial plate bare. Three distinct left subepandrial processes: a proximal hairy lobe, a dented distal hairy process (lsp1) and an upper dented process (lsp2).

Female. Unknown.

Distribution. Brazil, State of Santa Catarina.

Etymology. The species name is feminine and refers to one of the localities in which the species has been collected.

Comments. Coniceromyia franciscana , C. diaphaniptera , C. epicantha Borgmeier , C. maculipennis , C. vespertilio Schmitz and C. anacleti Borgmeier probably form a monophyletic group based on the presence of some male foretibia features, unique in the family ( Figs 26–41 ). The male foretibia chaetotaxy and the distinctive hypopygium of C. epicantha and C. franciscana suggest that conspicuous wing maculation, seen in C. franciscana , C. vespertilio , C. maculipennis , originated more than once in the evolution of the genus, i.e., species with patterned wing do not form a single clade. In Kung & Brown’s (2000) key, Coniceromyia franciscana would run into couplet 10; at that point the wing of C. franciscana do not have emargination in the wing margin as in C. vespertilio , but the wing patterning is rather similar to this species.
