Dewhurst, No. 883 (CANBERRA, LONDON, DAVIS, KIMBE, PORT MORESBY). Diagnosis. This is the largest bodied species of Cladobethylus , with males averaging twice the length of the known other species. Male insularis can be distinguished from aquilus , the only other species known from New Guinea by the longer malar space (4 midocellus diameters versus 3.5 in aquilus ), pronotum not blue-tinted, much broader zone of cross-ridging in the scapal basin, legs brown instead of yellow ( aquilus ) flagellomere I shorter (4.5 x as long as broad versus 5 x in aquilus ) and flagellomere XI shorter (5 x as long as broad versus 6 x in aquilus ). Features of female insularis not shared with other Cladobethylus include the bicolored antenna and legs, long clypeus (0.8 midocellus diameter long versus 0.3-0.6 midocellus diameters in other species), and narrow distance between the midocellus and nearest eye margin (up to 2 midocellus diameters versus 2.6-2.7 midocellus diameters in the others). Description. Male ( Fig. 4 ). Body length . 5-7 mm. Head ( Figs 6-8 ). Face about as long as broad across the eyes; genal area without foveae; midocellus 1.8 diameters from ocular margin; hindocelli 4 diameters from posterior margin of vertex; scapal basin with narrow, longitudinal submedial band of cross-ridges; malar space 3.5-3.8 midocellus diameters; subantennal distance 1 midocellus diameter long; flagellomere I 4 x as long as broad; flagellomere II 2.8-3.0 x as long as broad; flagellomere IX 5 x as long as broad, flagellar setae 0.7 midocellar diameter long; ocular setulae 0.4 midocellus diameter long. Mesosoma ( Fig. 9 ). Pronotum about as long as scutum; punctation on pronotum, scutum and mesopleuron large, deep and nearly contiguous punctuation, without scrobal sulcus or omaulus; scutellum polished with scattered tiny punctures; metapleuron polished, impunctate. Metasoma . Tergum I polished with few tiny highly scattered punctures; tergum II with two large ovoid patches of small punctures, 1 puncture diameter apart, separated medially by impunctate band and with broad apical impunctate band; terga III-IV with tiny punctures 1 puncture diameter apart, becoming sparser toward apical margin. Color . Head, meso- and metasoma black with metallic bluish green highlights dorsally on head, pronotum and scutellum, sometimes faint on metasomal terga; mandible and antenna dark brown; legs light reddish brown, except coxae dark brown to black basally; wing membrane brown-tinted, darkest in vicinity of stigma; wing veins dark brown. Female ( Fig. 5 ). Body length . 4.5-5.5 mm. As in the male, except face ( Fig. 10 ) about as long as broad across the eyes; malar space 3.6-3.8midocellus diameters; subantennal distance 0.8 midocellus diameter; flagellomere I 2.4 x as long as broad; flagellomere II long as broad; flagellomere IX 1.3 x as long as broad; scape, pedicel black, flagellomeres I-III white, remaining flagellomeres black; coxae, femora, mid and hindtibiae black basally, whitish apically; foretibia and tarsi brown; wing membrane brown-tinted with dark brown veins. Etymology. The species is named after the host species. Figures 4-5. Cladobethylus insularis , side views 4 Male 5 Female. Figures 6-10.
