Coniceromyia xiei sp. nov.

( Figs. 7E , 9K , 16E , 23B , 25R )

Diagnosis (male). Flagellomere 1 globose, forefemur with three ventral rows of very elongated thin setae ( Fig. 7E ), hind tibia with two dorsal setae in basal half, foremetatarsus with anterior bare excavation, ventral margin of excavation with a concavity near basal third ( Fig. 9K ).

Material examined. Holotype ♂, COLOMBIA: Huila: PNN Cueva de Los Guácharos: Cabaña Cedros , 1.62ºN, 76.10ºW, 21.xii–5.i.2002, Malaise trap, 2100m, C. Cortés col. ( IAVH) [LACM ENT 172212].

Description. Male. Body length, 3.0 mm. Head. Frons brown to dark brown, sparsely setulose, with weak median furrow; frontal setae slightly elongated. Flagellomere 1 brown, globose. Arista subapical, about five times flagellomere 1 length. Palpus light brown. Gena with two setae. Thorax. Scutum, scutellum, and pleural regions brown; anepisternum bare. Fore and mid leg yellowish-brown, hind leg light brown. Forefemur with three ventral rows of very elongated thin setae. Foretibia with two dorsal setae and anterodorsal row of strong setulae. Foremetatarsus with anterior bare excavation, anteroapical setulose process, ventral margin of excavation with a concavity near basal third, group of long setae at base of excavation, and strong seta at anteroapical process base ( Fig. 9K ). Foremetatarsus ratio 0.23. Posterior face of hind femur with narrow basoventral band of tiny blunt setulae ( Figs. 23B ). Hind femur height/length ratio, 0.37. Hind tibia with two dorsal setae in basal half. Wing ( Fig. 16E ). Margin slightly projected as a lobe between M 1 and M 2. Costa swollen, 0.44 of the wing length; R 2+3 absent; M 1 concave, not curved posteriorly at apex; M 2 slightly sinuous, CuA 1 -M 2 /M 2 -M 1 ratio 1.47; CuA 1 sinuous. Halter white. Abdomen. Tergites brown, with shining pubescence. Hypopygium light brown ( Fig. 25R ). Left epandrial process with a medially-directed lobe near hypoproct and an apical lobe. Other characteristics could not be observed as we decided to not dissect the only known specimen of this species.

Distribution. Known from a single mid-elevation site in Colombia.

Etymology. Named for the LACM Entomology Collections Manager, Weiping Xie, who has contributed substantially to the LACM collection and to our work on phorids.
