Cladobethylus ceylonicus Krombein 1980: 253. Holotype male; Sri Lanka: Central Prov., Kandy Dist., Adams Peak (USNM).

Diagnosis.

The most distinctive features of Cl. ceylonicus are the long first and second flagellomeres, a characteristic shared with Cl. acehensis and Cl. densepunctatus . However, Cl. ceylonicus can be distinguished from these and other species by the combination of these features, along with the densely punctate second metasomal tergum, asymmetrical apical male flagellomeres and short subantennal distance.

Scapal basin impunctate, with short strip of cross-ridges on either side of narrow medial stripe; clypeus short and subtruncate apically, subantennal distance 0.4 MOD long; malar space 3.8 MOD long wide; head about as long as wide; interocular distance 1.9 × eye width in front view; midocellus 2.2 MOD from ocular margin; ocelli arranged in isosceles triangle; hindocelli separated from ocular margin by 1 diameter; postocular distance 1.6 MOD wide; flagellomere I 4.5 × as long as broad, setae 0.5 × as long as flagellomere breadth; flagellomere II 3.3 × as long as broad; flagellomere XI 5 × as long as broad; flagellomeres VIII-X asymmetrically bulging submedially. Mesosoma.
