( Figs 2 View FIGURES 1 – 12 , 23 View FIGURES 22 – 30 , 43 View FIGURES 42 – 50 , 63, 64 View FIGURES 59 – 67 )
Description. MALE. Body length 4.9 mm. LFW 3.3 mm. Color. Head, clypeus and mesosoma black; antenna dark castaneous; mandible and metasoma castaneous; legs light castaneous; wings brownish.
Head ( Fig. 2 View FIGURES 1 – 12 ). Mandible with five apical teeth; uppermost one blunt, others angulate; large, subequal in length. Median clypeal lobe convex; apical margin strongly medially ventrad, with median tooth conspicuous; carina high, arched in profile. Antennal torulus strongly prominent. Flagellomeres median-sized; four first antennomeres in ratio about 13:4:7:7; pedicel short, 1.2 × as long as wide; flagellomere I 1.80 × as long as wide; flagellomere IX 1.80 × as long as wide; flagellar pubescence erect, about half of diameter of flagellomeres. Frons polished; densely punctate. WH 0.90 × LH. WF 0.75 × WH. WF 1.50 × HE. Eye small, salient; pilosity sparse. Ocellus small. DAO 0.20 × HE; frontal angle of ocellar triangle acute. WOT 2.30 × DAO. OOL 1.16 × WOT. Distance of posterior ocellus to vertex crest 1.66 × DAO. VOL 0.90 × HE. Temple subparallel. Vertex straight. Occipital carina illdefined.
Mesosoma ( Fig. 23 View FIGURES 22 – 30 ). Pronotal disc and mesonotum polished; densely punctate. Pronotal collar long. Pronotal declivity low. Pronotal disc 0.34 as long as wide. Notauli strongly conspicuous; complete; convergent. Parapsidal furrow complete. Scutellar furrow long, slender, shallow, scrobiculate, posterior margin straight. Median region of scutellum not punctate. Median region of metanotum very short, wide. Inner foveae of metanotal furrow not delimited. Propodeal disc 1.16 × as long as wide; 0.61 × as high as long; basal triangle inconspicuous, finely rugulose, ototherwise disc strigulate or polished; median carina absent; paramedian carina absent; lateral carina present, inconspicuous; sublateral carina absent; transversal carina absent; declivity strigulate; side of propodeum polished. Mesopleuron slightly coriaceous; callus absent; fovea deep; mesopleural pit absent. Metacarpus 0.23 × radial vein; discoidal vein strongly pigmented, not interstitial with median; first recurrent slightly pigmented; subdiscoidal vein slightly pigmented.
Metasoma. Hypopygium ( Fig. 43 View FIGURES 42 – 50 ) 1.0 × as long as wide; posterior margin slightly trilobate; median lobe angulate, wide; lateral lobe convex, very short; lateral margin slightly convex; anterior pigmented line ill-defined, slender; median stalk short; lateral stalk absent. Genitalia ( Figs 63–64 View FIGURES 59 – 67 ): aedeagus uniformly wide; apical margin of ventral paramere convex; dorsal paramere as wide as ventral one, glabrous; basivolsella not excavated; inner margin of cuspis sinuous; genital ring long.
FEMALE unknown.
Material examined. Holotype ♂. N. VIETNAM, Tonkin, Tay Con Linh, Cao Bo Vi, nr. base-camp, 1240 m, 8–13.IX.2000, X. H. Gimug & M. P. Quy, RMNH’01. Paratypes. 2 ♂, N. VIETNAM. Tonkin, Tay Con Linh, Cao Bo Vi, c 1300 m, 16–23.IX.2000, May Phu Quy, RMNH’01.
Distribution. Vietnam ( Tonkin).
Variation. Metacarpus inconspicuous.
Remarks. Caloapenesia arbeni sp. nov. resembles C. thailandiana by presents head elongate; occipital carina inconspicuous; posterior margin of hypopygium with median lobe angulate; aedeagus uniformly wide. But C. arbeni sp. nov. presents texture coriaceous; eye and ocelli smaller than C thailandiana ; propodeal disc without paramedian carina conspicuous; lateral lobe of posterior margin of hypopygium inconspicuous.
