Notauli strongly conspicuous; complete; slightly convergent. Parapsidal furrow complete. Scutellar furrow long, slender, scrobiculate, posterior margin straight. Median region of scutellum not punctate. Median region of metanotum short, slender. Inner foveae of metanotal furrow not delimited. Propodeal disc 1.20 × as long as wide; 0.55 × as high as long; basal triangle inconspicuous, rugulose, ototherwise disc strigulate or polished; median carina absent; paramedian carina conspicuous, short; lateral carina conspicuous; sublateral carina present, inconspicuous; transversal carina absent; declivity strigulate; side of propodeum polished. Mesopleuron polished; callus absent; fovea deep; mesopleural pit absent. Metacarpus 0.60 × radial vein; discoidal vein slightly pigmented, not interstitial with median; first recurrent slightly pigmented; subdiscoidal vein strongly pigmented.

Metasoma. Hypopygium ( Fig. 51 ) 1.07 as long as wide; posterior margin slightly trilobate; median lobe angulate, wide; lateral lobe convex, short; lateral margin straight; anterior pigmented line ill-defined, slender; median stalk short; lateral stalk present, rectangular, inconspicuous. Genitalia ( Figs 79–80 ): aedeagus basally wide and narrowing apicad; apical margin of ventral paramere convex; dorsal paramere wider than ventral paramere, glabrous; basivolsella not excavated; inner margin of cuspis convex; genital ring short.

FEMALE unknown.

Distribution. Thailand (Prachuab Khiri Khan).

Remarks. Caloapenesia leptata sp. nov. resembles C. philippinensis by presents head wide, ocellus and eye large, mandible with five teeth angulate and subequal in length. But Caloapenesia leptata sp. nov. presents clypeus rounded; occipital carina not visible in dorsal view; Notauli slender, complete; discoidal vein almost interstitial with median vein; mesosoma dark castaneous. The holotype of C. philippinensis was not founded for comparison.
