Median clypeal lobe convex; apical margin strongly medially ventrad, with median tooth slightly conspicuous; carina high, arched in profile. Antennal torulus slightly prominent. Flagellomeres short; four first antennomeres in ratio about 16:5:6:6; pedicel long, 1.25 × as long as wide; flagellomere I 1.50 × as long as wide; flagellomere IX 1.25 × as long as wide; flagellar pubescence erect, about half of diameter of flagellomeres. Frons polished; densely punctate. WH 0.91 × LH. WF 0.72 × WH. WF 1.71 × HE. Eye small, salient; pilosity abundant. Ocellus small. DAO 0.15 × WF; frontal angle of ocellar triangle acute. WOT 2.75 × DAO. OOL 1.20 × WOT. Distance of posterior ocellus to vertex crest 2.0 × DAO. VOL 1.07 × HE. Temple parallel. Vertex slightly convex. Occipital carina complete, not visible in dorsal view.
Mesosoma ( Fig. 24 View FIGURES 22 – 30 ). Pronotal disc and mesonotum polished; densely punctate. Pronotal collar long. Pronotal declivity low. Pronotal disc 0.37 × as long as wide. Notauli strongly conspicuous; complete; convergent. Parapsidal furrow complete. Scutellar furrow long, slender, shallow, scrobiculate, posterior margin sinuous. Median region of scutellum not punctate. Median region of metanotum short, wide. Inner foveae of metanotal furrow not delimited. Propodeal disc 0.86 × as long as wide; 0.61 × as high as long; basal triangle conspicuous, rugulose, ototherwise disc strigulate; median carina absent; paramedian carina conspicuous, long; lateral carina conspicuous; sublateral carina conspicuous; transversal carina absent; declivity strigulate; side of propodeum coriaceous. Mesopleuron polished; callus absent; fovea deep; mesopleural pit absent. Metacarpus 0.41 × radial vein; discoidal vein strongly pigmented, not interstitial with median; first recurrent not pigmented; subdiscoidal vein slightly pigmented.
Metasoma. Hypopygium ( Fig. 44 View FIGURES 42 – 50 ) 1.05 × as long as wide; posterior margin strongly trilobate; median lobe convex, wide; lateral lobe convex, short; lateral margin slightly convex; anterior pigmented line ill-defined, slender; median stalk short; lateral stalk present, rectangular, conspicuous. Genitalia ( Figs 65–66 View FIGURES 59 – 67 ): aedeagus basally wide and narrowing apicad; apical margin of ventral paramere convex; dorsal paramere as wide as ventral one, glabrous; basivolsella not excavated; inner margin of cuspis convex; genital ring short.

Distribution. Thailand (Loei); Vietnam (Thua Thien Hue).
Remarks. Caloapenesia diba sp. nov. resembles C. rikawa sp. nov. by presents head rounded; clypeus rounded; ocellus small; eye small; flagellomeres short. But C. diba sp. nov. presents head elongate; eye smaller than in C. rikawa sp. nov.; ocelli separated; clypeus castaneous; antennae light castaneous; uppermost tooth not with upper margin forming cutting edge; hypopigial median lobe shorter than in C. rikawa sp. nov.; lateral stalk conspicuous and rectangular.
