( Figs. 45–47 View FIGURES 45 – 47 , 150 View FIGURES 139 – 157 , 202 View FIGURES 191 – 202 , 262-263 View FIGURES 258 – 263 )

Coniceromyia boliviana Borgmeier, 1950: 288   , textfig. 11, plate xvii, fig. 2–3.

Diagnosis (male). Wing vein M2 almost straight on basal half, curved posteriorly at apex; separation between M2 and CuA1 wide (antero-posterior distance between M2 and CuA1 at CuA1 apex about 2.4 the distance between M1 and M2 at the same level).

Material examined. Holotype ♂, BOLIVIA: Sorata , 22.xii.1902 (no additional information) ( MZSP)   ; 1♂ paratype, same data as holotype   . New material: BOLIVIA: 1♂, La Paz: 40 km N Caranavi: Cumbre Alto Beni, 15.83ºS, 67.56ºW, 1600 m, 7–14.iv.2004, Malaise trap, B. Brown, E. Zumbado col. ( LACM). GoogleMaps  

Redescription. Male. Body length, 2.0–3.0 mm. Head. Frons dark brown, sparsely setulose, with welldefined median furrow. Flagellomere 1 dark yellow, pubescent, conical, very elongated. Arista apical, pubescent, about half of the flagellomere 1 length. Palpus brown; two genal setae. Thorax. Scutum, scutellum and pleural regions dark brown, anepisternum bare. Legs yellowish-brown, thin, elongated. Foretibia with 2–3 dorsal setae, anterodorsal row of strong setulae and apical dorsal setula ( Fig. 150 View FIGURES 139 – 157 ). Foremetatarsus with anteroapical setulose process, anterior excavation, long seta at base of excavation, seta at base of the anteroapical process, and posterior strong apical seta. Hind femur not swollen (height/length ratio, 0.35), with posteroventral group of tiny blunt setulae with semicircular distribution, tapering toward ventral margin ( Fig. 262–263 View FIGURES 258 – 263 ). Hind tibia with one dorsal seta. Wing ( Fig. 202 View FIGURES 191 – 202 ). Costa not swollen, 0.37 of the wing length; M1 slightly concave, curved posteriorly at apex; M2 slightly sinuous on proximal half, curved posteriorly at apex; antero-posterior distance between M2 and CuA1 at CuA1 apex about 2.3 times the distance between M1 and M2 at the same level; CuA1 sinuous. Halter whitish-yellow. Abdomen. Tergites dark brown, with lighter posterior band and shining pubescence. Hypopygium light brown ( Figs. 45–47 View FIGURES 45 – 47 ). Epandrium covered with microtrichia mostly dorsally, proximal lateral areas bare; epandrial dorsal and left sutures present. Left epandrial process bifurcated into a dorsal and a ventral lobe. Ventral lobe with many strong short setulae at medial face. Dorsal lobe with medial setulose elevation ( Fig. 47 View FIGURES 45 – 47 , black arrow). Right subepandrial plate setulose, expanded posteriorly, forming a forceps with the left epandrial process. Hypoproct with two to four setae. Right lobe of hypandrium with lateral projection.

Geographical distribution. Bolivia.

Comments. The description of the hypopygium and of foretibia features are the most important additions to the original description of this species. Coniceromyia boliviana   has a highly modified hypopygium and it is the only species in the genus with the left epandrial process clearly bifurcated and the right subepandrial plate projected posteriorly. The holotype is severely damaged, with head and terminalia separated from the thorax.
