Dorsal half of occipital carina present, high, with side foveolate; ventral half of occipital carina present, complete, high, with side foveolate. LH 1.1 × WH. WF 1.5 × HE. WF 0.6 × WH. OOL 0.81 × WOT. VOL 0.83 × HE. Distance of posterior ocellus to vertex crest 2.33 × DAO.

Mesosoma ( Figs 4, 5 ). Pronotal disc 0.6 × as long as wide; sparsely foveolate; plate groove present; anterior slope straight; anterior margin straight, with transverse carina, with anterior corner rounded; trapezoidal shaped, with side straight; longitudinal pronotal furrow present, complete, deep; posterior margin straight. Propleuron with epicoxal sulcus, deep, foveolate. Pleurosternum with epicoxal sulcus, foveolate. Mesoscutum coriaceous, long; longitudinal mesoscutal furrow absent; notaulus complete, convergent posteriorly, deep, narrow, polished; parapsidal furrow incomplete, well impressed, parallel. Scutellar groove narrow, fused with axilla, arched, not dilated at ends; scutoscutellar sulcus conspicuous; scutellum short, coriaceous, plane, not touching propodeal disc; axilla polished, shallow. Metanotum overlapping lateral region of scutellum. Propodeal disc as long as half width, with central fovea fused with propodeal triangle fovea; median carina complete; with longitudinal ridge between median and inner discal carinae; sublateral and inner discal carina fused anteriorly; spiracle elliptical; inner discal carina complete; sublateral carina present; lateral carina present; lateral margin sculpture coriaceous; posterior carina complete; posterior spine of propodeum present, very short, thick, parallel. Declivity of propodeum areolate, with median carina, without lateral carina. Lateral surface of propodeum strigate, without superior carina, without posterior carina. Mesopleuron foveolate, with subtegular fovea continuous with episternal furrow; mesopleural sulcus present, complete, foveolate; episternal furrow with inner margin striate.

Wings. Macropterous. Tegula separated of mesoscutum. Fore wing with sparse pilosity; costal vein absent; median cell shorter than submedian cell; basal vein angulate; transverse median vein biangulate; nebulous cubital vein absent; nebulous anal cubital vein absent; stigma subdeveloped, with distal margin truncate; radial vein slightly curved forward, giving raise at distal margin of stigma. Hind wing with costal vein short; with anal vein short; with one proximal hamuli; with three distal hamuli, first hamuli widely separated from others.

Legs. Metacoxa with dorsal expansion, without ventral expansion. Protibia short [1.5× first tarsomere length], with protibial spur long [longer than half length of first tarsomere]. Tarsi with tarsomeres 1–4 progressively shorter distad, cylindrical; tarsal claw with two sharpened teeth, curved posterad; arolium simple, apex angled, and slender.

Metasoma. 2.02 × longer than wide; tergum 1 with ventral region coriaceous, with lap of lateral margin, without lateral pilosity; tergum 2 with dorsal region polished, without lateral pilosity, with ventral region polished; terga 3–6 with dorsal region polished, with ventral region polished; with posterior margin of tergites straight, with sparse setae at posterior margin of terga 2–6.

Genitalia ( Figs 67, 68 ). Genital ring protruding dorsally, with distal margin rounded and emarginated. Basivolsella fully outlined from basiparamere, with sparse line of hairs. Paramere fully divided into two arms; dorsal arm of paramere as long as ventral arm, club-shaped, and with basal margin thin; ventral arm of paramere slender, apex sparse hairy, inner margin straight. Cuspis birramous, with arms distinct; ventral arm aligned with dorsal arm apex, slender, and thin, with apex rounded; dorsal arm wide, and with apex rounded. Aedeagus slender; with pair of apical lobes, with apex aligned with paramere apex, lobes touching each other, with apical margin rounded, lateral of margin of basal portion slightly convex; apodeme parallel, with base straight.

FEMALE unknown.

Remarks. This species is similar to Anaylax dalmaticus Móczár, 1970 by having the median clypeal lobe rounded; the temple divergent; the pronotal disc with anterior angle rounded and sparsely foveolate; the propodeum as long as half width. However A. betsileo sp. nov. has the head longer than wide; the antenna with pedicel as long as first flagellomere; the frons densely foveolate and without frontal sulcus; the longitudinal pronotal furrow present; the scutellar groove not dilated at ends; the propodeal disc with longitudinal ridge between median and inner discal carina; the posterior spine of propodeum present, whereas A. dalmaticus has the head as long as wide; the antenna with pedicel shorter than first flagellomere; the frons sparsely foveolate and with frontal sulcus; the longitudinal pronotal furrow absent; the scutellar groove dilated at ends; the propodeal disc without longitudinal ridge between median and inner discal carina; the posterior spine of propodeum absent.
