Coridromius ruwenzorii View in CoL , new species Figures 5, 6, 18F–H, map 2

HOLOTYPE: Female : UGANDA: Ruwenzori Range, Misigo, 0.24719 ° N 29.82239 ° E, 2606 m, 02–03 Jul 1952, D.S. Fletcher ( AMNH _ PBI 00178010 About AMNH ) ( BMNH). GoogleMaps

DIAGNOSIS: Identified by the following combination of characters: smooth and rounded head; punctate hemelytra; brownish orange coloration with two large dark brown spots on scutellum; unique female paragenitalia. The male of ruwenzorii is unknown. Known only from a single female specimen, this species is nearly identical to bulbopella , however, the paragenitalia lack the welldeveloped cup-and-bulb structure of the latter, appearing instead as a much-reduced version thereof, with an additional desclerotized swelling of the first right dorsal laterotergite.

DESCRIPTION: COLORATION (figs. 5, 6) Head: Concolorous orange-brown; vertex without vittae; apex of clypeus slightly brown; maxillary plate brown. Antenna: Mostly yellow; AI with broad brown apical annulation; AII with brown apical annulation; AIII and AIV brown. Thorax: Pronotal collar yellow; pronotum orange-brown with very faint yellow medial stripe, posterior tinged orange; mesoscutum tinted orange; scutellum orange-brown with two large brown markings; thoracic pleura brownish yellow. Hemelytra: Mostly orange-brown, tinted orange at base; claval commissure faintly brown; membrane pale yellow-brown with darker brown veins. Abdomen: Yellowbrown, more orange along dorsal margin, with faint red markings laterally. Legs: Yellow-brown, paler basally, pro- and mesofemora with brown subapical band; metafemur with brown transverse stripes, apically tinted orange. SURFACE AND VESTI- TURE (figs. 5, 6, 18F–H): Head smooth with a few shallow punctures on vertex, vertex coarsely punctate; pronotum, scutellum (fig. 18F–G), and hemelytra with large, evenly spaced punctures; propleuron, met- epimeron, and cuneus impunctate; clothed in short, white, decumbent setae. STRUC- TURE (figs. 5, 6, 18F–H) Head: Frons with broad medial tumescence contiguous with raised lateral tubercles adjacent to eyes; posterior margin of head distinctly rounded. Thorax: Pronotum broad and evenly round- ed, margins thinly carinate, anterolateral margins adjacent to callar region depressed, submarginal region of humeral angles weakly excavated, posterior margin weakly upturned, callar region weakly developed (fig. 18F); proepisternum bilobed; posterior margin of metepimeron broadly rounded (fig. 18H); metanotum prominent and flared; apex of scutellum not a swollen lobe. Hemelytra: Costal margin weakly flared posteriorly, carinate; cuneus small. Legs: Metatibial spines long and thick. Abdomen: Posterolateral margin of abdominal sternite II rounded, not sharply angular (fig. 18H). MALE GEN- ITALIA: Unknown. FEMALE PARAGEN- ITALIA (fig. 18F–G): Inner margins of right dorsal laterotergites II and III weakly lobate, laterotergite I swollen and desclerotized, posterior margin of right abdominal sternite II carinate and slightly flared, indicating probable sight of copulation.

ETYMOLOGY: Named for the Ruwenzori range in Uganda, from which the only specimen has been collected.

HOST: Unknown.
