Most of head finely, transversely rugulose with underlying finely alveolate areas visible between rugulae, the rugulae usually subparallel but occasionally branching, except as follows: parascrobal area of head with raised cristae formed by 5 distinct carinate elevations, and with several smaller and less distinct carinae dorsad these; vertex with smooth area between the parascrobal crests from median ocellus to slightly beyond posterior limit of the crests; interantennal region with sharp carina between toruli reaching less than halfway to median ocellus; gena with smooth and bare area adjacent to eye, but the area gradually becoming setose posteriorly; occipital carina absent, although occiput relatively distinctly differentiated from vertex by an abrupt change in curvature and sculpture.
Clypeus not distinct, distance between anterior tentorial pits to mouth margin less than width of scape; clypeal margin broadly and shallowly concave, not distinct from curvature forming rest of the mouth margin. Labrum partially visible in non-dissected specimens, with thick golden setae ( Fig. 2 View FIGURE 2 B). Mandible with an undivided cutting edge, with numerous long setae arising from contour that contacts mouth margin when mandibles are fully open. Antenna ( Fig. 2 View FIGURE 2 D) with tip of scape reaching or slightly exceeding median ocellus height but not extending above vertex; F1 (anellus) without evident placoid or socketed sensilla but with a few tiny setae; all funicular segments cylindrical, with numerous rows of longitudinal sensilla and appressed dark setae; F9–F11 forming club, with a small micropilose region subapico-ventrally on F11. Length:width ratios of antennal segments as follows: scape (0.84–0.97:0.11–0.16), pedicel (0.20–0.27:0.09–0.11), F1 (0.08– 0.09:0.08–0.11), F2 (0.62–0.69:0.09–0.11), F3 (0.61–0.67:0.09–0.11), F4 (0.61–0.67:0.09–0.10), F5 (0.50– 0.58:0.09–0.10), F6 (0.39–0.42:0.11–0.12), F7 (0.23–0.26:0.12), F8 (0.20–0.25:0.12), F9 (0.27–0.30:0.16– 0.17), F10 (0.16:0.14–0.16), F11 (0.12:0.09–0.11).

Pronotum with smooth area on lateral surface in posterior half ( Fig. 3 View FIGURE 3 B). Pronotum length:width = 2.00–2.14:0.65–0.95, not differentiated into collum and collar, anteriorly very narrow, almost tonguelike, and with narrow hyaline rim, but gradually becoming broader and higher posteriorly with a slight dorsal concavity before posterior margin; pronotal incisions for mesothoracic spiracles not developed. Propleuron length: width = 1.40–1.50:0.30–0.36, medioventral margins straight and closely abutting along major part of propleura but diverging posteriorly and leaving most of prosternum exposed ( Fig. 3 View FIGURE 3 D: s1); ventral surface sparsely pilose and mostly covered by coarse striae but with fine reticulation posteriorly; lateral surface also finely reticulate, but anterodorsal surface completely smooth; cervical prominence ( Fig. 3 View FIGURE 3 C: cp) exposed at anterior margin of propleuron, anteriorly elongate and slightly upcurved, with three rows of short setae: one row along mesal ventral margin and two parallel rows extending ventrally from anterodorsal margin ( Fig. 3 View FIGURE 3 C). Prosternum (total) length:width = 0.37–0.42:0.44–0.51; only anterior margin covered by propleura, posterior margin straight, carinate without median process ( Fig. 3 View FIGURE 3 D); ventral prosternal surface slightly reticulate, pilose, completely divided by medial prodiscrimenal line.

Mesoscutal midlobe more strongly rugulose in posterior half than anterior half, the sidelobes more uniformly strongly rugulose.
Mesoscutellar-axillar complex length:width = 1.17–1.39:0.78–0.89. Mesoscutellum mostly finely and densely alveolate except for occasional rugula extending from axilla, but with a shallow, broad, posteriorly narrower and shallower mesal longitudinal depression extending to frenal groove, the depression with finer alveolate sculpture than rest of mesoscutellum. Frenum with very fine and shallow sculpture, less alveolate than for rest of mesoscutellum. Axillae with dorsal surfaces large and abutting medially, finely transversely rugulose with underlying finely alveolate areas visible between rugulae except with nearly rectangular smooth depression anterolaterally ( Fig. 3 View FIGURE 3 E: ax), the smooth depression bordered posteriorly by a carina that extends medially partly across the axillae; dorsal axillar surface with posterior half much more densely setose than anterior half, lateral panel of axilla mainly smooth, but with tiny punctures dorsally and with slight reticulation ventrally. Mesoscutellum with axillulae barely differentiated and with flat surface; frenum less than one tenth mesoscutellar length, with frenal line extremely shallow and abruptly arching posteriad at point where tiny posterior pair of mesoscutellar setae are positioned.

Posterior edge of mesopleuron (what may be mesepimeron) mostly smooth and bare, but with some rugae and setae in a middle strip that becomes broader dorsally. Mesopleural sulcus obscure, but marked by sunken area that is sculptured in dorsal half and smooth and broadened in ventral half. Transepimeral and transepisternal divisions not apparent. Acropleuron small, transverse without distinct margins (acropleural sulcus), the posteroventral margin indicated by round depression and surface striate; mesopleuron otherwise with smooth area below acropleuron, posterolaterally with fine reticulation, and anterolaterally and ventrally with tiny piliferous punctures; mesopleural sulcus, transepimeral sulcus and transepisternal sulcus absent externally; mesodiscrimenal line developed as shallow sulcus with mesofurcal pit just anterior to carinate mesotrochantinal plate; mesocoxal foramina completely enclosed by sclerotized cuticle.
