Cladobethylus gilbus Kimsey 1986:157. Holotype male; Malaysia: Pasoh Forest Res., Negri Sembilan (AEI).
Diagnosis.
Cladobethylus gilbus shares the nearly impunctate second metasomal tergum with Cl. darlingi , Cl. acehensis and Cl. densepunctatus . In males it can be distinguished from those species by the narrow malar space (less than 2.8 midocellar diameters), flagellomere I less than 4 × as long as broad, flagellomere II more than 2.5 × as long as broad, flagellomere XI 7 × as long as broad and postocular distance less than 1 MOD. Females have the basal three flagellar segments paler than the rest of the flagellum, very short flagellomeres I and II and malar space 4.5 midocellar diameters wide (shared with Cl. aquilus ).
Male description.
Body (Figs 21 View Figures 20–25 , 22 View Figures 20–25 ). Length 3.5-4.0 mm. Head. Scapal basin with narrow band of cross-ridges separated by smooth medial band; head venter without ovoid foveae along midline of gular area, gular area punctate; malar space 2.6 MOD long; head as wide as long; interocular distance 1.5 × eye width in front view; midocellus 1.4 MOD from ocular margin; ocelli arranged in a nearly equilateral triangle; hindocelli separated from ocular margin by 1 diameter; subantennal distance 0.6 MOD; clypeal apex truncate to slightly concave; flagellomere I 3.6 × as long as broad, setae length 0.4 × flagellomere breadth; flagellomere II 2.6 × as long as broad; flagellomere IX 7 × as long as broad; flagellomeres VIII-X slightly lobate submedially. Mesosoma. Pronotum 0.9 × as long as scutum; mesopleural punctures 0.2-0.5 puncture diameters apart; metapleuron with zone of cross ridging below hindwing base; propodeum laterally cross-ridged, posteromedially with subrectangular enclosure. Metasoma: terga I and II impunctate; terga III-V with basal band of dense, minute, contiguous punctures. Color: body black, except pronotum, scutum, scutellum and metanotal triangle with metallic blue highlights; antenna and legs including coxae yellow; wing membrane light brown tinted, with brown veins.
Female description.
Body (Figs 23 View Figures 20–25 , 24 View Figures 20–25 ). Length. 4.0-5.0 mm. Head. Frons punctures contiguous to 0.5 puncture diameters apart; scapal basin primarily smooth with short strip of cross-ridges on either side of broad medial stripe; head venter with ovoid fovea on either side of gular midline (Fig. 25 View Figures 20–25 ), gular area punctate; clypeus subtruncate apically; subantennal distance 0.8 midocellar diameter; malar space 4.5 midocellar diameters long; head about as long as wide; midocellus 2 × midocellar diameters from ocular margin; ocelli arranged in nearly equilateral triangle; hindocelli separated from ocular margin by one diameter; flagellomere I as long as broad; flagellomere II 0.6 × as long as broad; flagellomere X twice as long as broad. Mesosoma. Pronotum about as long as scutum; mesopleuron with irregular scrobal sulcus, punctures contiguous to 0.5 puncture diameter apart; metapleuron smooth and impunctate; propodeum laterally polished, impunctate, posteromedially with subrectangular enclosure smooth but somewhat irregular. Metasoma. Tergum I impunctate; tergum II punctures 10 puncture diameters apart becoming slightly denser laterally; terga II-IV punctures 1-2 puncture diameters apart with impunctate rim. Color. Body black, except head and pronotum with faint metallic blue highlights; legs including coxae yellow; scape yellowish brown becoming darker ventrally; pedicel and flagellomeres I-III yellow, remaining flagellomeres brown dorsally becoming yellow ventrally; wing membrane brown-tinted, veins dark brown.
Distribution.
MALAYSIA: Negeri Sembilan, Pasoh Forest Res.; 106 males and 50 females were examined (AEI, BME). Males and females were found in nearly every month over a two-year period of Malaise trap collecting at this site (Fig. 20 View Figures 20–25 ).
