Cladobethylus aquilus Kimsey 1986: 157. Holotype male; New Guinea: Bulolo (AEI).

Diagnosis.

Cladobethylus aquilus males most closely resemble those of Cl. ceylonicus and Cl. insularis based on flagellomere I 4.0-4.5 × as long as broad, the dark brown antenna, nearly impunctate metasomal tergum II, and reduced cross ridging in the scapal basin. However, Cl. aquilus can be distinguished from those and other species by the combination of the longer subantennal distance, lack of metallic blue highlights, slightly medially lobate apical flagellomeres, and flagellomere XI 6 × as long as broad. Females most closely resemble those of Cl. insularis and Cl. thailandicus based on the bicolored antenna and flagellomere II about as long as broad. They can be distinguished from these and other species by the scapal basin lacking cross ridges, bicolored legs and densely punctate metasomal tergum II.

Male description.

Body (Figs 4 View Figures 4–11 , 5 View Figures 4–11 ). Length 3.0-4.0 mm. Head. Frons with punctures 0.5-1.0 puncture diameter apart; scapal basin impunctate, with narrow band of cross-ridges sublaterally; clypeus long and subtruncate apicomedially; subantennal distance 1 MOD long; malar space 3.4 MOD long; gular area flattened, without depression or pits; head 0.9 × as long as broad, interocular distance twice eye width in front view; postocular distance 1.4 midocellar diameters wide; vertex broadly rounded posterolaterally in dorsal view; midocellus 2.2 MOD from ocular margin; ocelli arranged in isosceles triangle; hindocelli separated from ocular margin by 1.0 diameters; flagellomere I 4 × as long as broad, setae 0.5 × as long as flagellomere breadth; flagellomere II 2.8 × as long as broad; flagellomere IX 6 × as long as broad; flagellomeres VIII-X slightly lobate submedially. Mesosoma. Pronotum medially 0.8 × as long as scutum in dorsal view; mesopleural punctures contiguous to 0.5 puncture diameter apart; metapleuron polished, impunctate; propodeum laterally polished, impunctate, posteriorly with posteromedial subrectangular enclosure. Metasoma. Tergum I punctures 5-10 puncture diameters apart; tergum II with punctures, 1-2 puncture diameters apart, separated medially by impunctate medial stripe; tergum III-IV punctures 1-2 puncture diameters apart. Color. Body black, without metallic highlights; legs yellow; antenna brown to blackish; wing membrane light brown-tinted, with dark brown veins.

Female description.

Body (Figs 6 View Figures 4–11 , 7 View Figures 4–11 ). Length. 4.0 mm. Head. Frons punctures contiguous to 0.5 puncture diameter apart; scapal basin impunctate, with narrow vertical band of cross-ridges submedially; clypeus short in front view, projecting ventrally, projection truncate apicomedially; subantennal distance 0.8 MOD wide; malar space 4.5 MOD long; head 0.9 × as long as broad, interocular distance 1.2 × eye width in front view; postocular distance 1 midocellar diameter; vertex rounded angulate posterolaterally in dorsal view; midocellus 2.3 MOD from ocular margin; ocelli arranged in nearly equilateral triangle; hindocelli separated from ocular margin by 1 diameter; flagellomeres appearing somewhat bead-like, broader medially than apically; flagellomere I twice as long as broad; flagellomere II as long as broad; flagellomere X twice as long as broad. Mesosoma. Mesopleural punctation contiguous; metapleuron polished with metapleural-propodeal suture foveate; propodeum polished below wing. Metasoma. Tergum I punctures 2-5 puncture diameters apart with impunctate medial stripe; tergum II with punctures, 1-2 puncture diameters apart, separated medially by impunctate medial stripe; tergum III-IV punctures 1-2 puncture diameters apart. Color. Body black, without metallic highlights; coxae and tarsi brown, femora and tibia basally brown, apically white; scape, pedicel brown to dark brown, flagellomeres I-III at least partly white, remainder of flagellomeres dark brown; wing membrane light brown tinted, with dark brown veins.
