Propodeal disc 1.13 × as long as wide; 0.57 × as high as long; basal triangle conspicuous, rugulose, rest of disc polished; median carina absent; paramedian carina inconspicuous, long; lateral carina absent; sublateral carina absent; transversal carina absent; declivity strigulate; side of propodeum polished. Mesopleuron polished; callus absent; fovea shallow; mesopleural pit present. Metacarpus 0.26 × radial vein; discoidal vein slightly pigmented, not interstitial with median; first recurrent slightly pigmented; subdiscoidal vein slightly pigmented.

Metasoma ( Fig. 40 ). Hypopygium ( Fig. 56 ) 1.17 × as long as wide; posterior margin straight with a median lobe; median lobe convex, wide; lateral margin straight; anterior pigmented line ill-defined, wide; median stalk short; lateral stalk present, rectangular, inconspicuous. Genitalia ( Figs 89–90 ): aedeagus uniformly wide; apical margin of ventral paramere convex; dorsal paramere as wide as ventral one, glabrous; basivolsella slightly excavated; inner margin of cuspis sinuous; genital ring short.

FEMALE unknown.

Remarks. Caloapenesia sabeli sp. nov. resembles C. thailandiana by present ocellus large; lateral stalk of hypopygium rectangular; aedeagus uniformly wide. But C. sabeli sp. nov. presents temple divergent; ocellus and eye smaller than C. thailandiana ; lateral lobe of posterior margin of hypopygium inconspicuous. Caloapenesia sabeli sp. nov. also resembles C. supra sp. nov. by present temple divergent; ocellus large; teeth large; lateral stalk of hypopygium rectangular; aedeagus uniformly wide. But C. sabeli sp. nov. presents eye very smaller than in C. supra sp. nov.; lateral lobe of posterior margin of hypopygium inconspicuous.
