Head about as long as broad, longer than high, circular in frontal view. Vertex and posteroventral surface strongly rounded, anterior surface flat, with short genae (ca. 0.2 eye length) projecting into cheek-like lobe anteroventrally above mandible insertion. Ocelli distinct, positioned on small, raised, triangular prominence; ocellar diameter as broad as base of first antennomere, interocellar distance about one ocellar diameter. Compound eyes bulging, oval, 0.6 as broad as long, removed from lateral margins of head capsule. Antennae inserted between compound eyes below their midlength, closely flanking lateral edges of clypeus at base of horn's stalk; base of antenna with basal bulb exposed, inserted within thick annular torulus opening obliquely dorsad; antenna elongate; scape ca. 0.8 head length, weakly arched, cylindrical; pedicel very short, 0.2 scape length, about as long as wide, slightly broadened apically; first flagellomere longest antennomere, about 8 as long as wide (assessed from

Posterior and lateral margins of clypeus (epistomal sutures) visible, indicating the horn is the result of an elevated anterior margin. Clypeal horn short (HoI 28e30), expanded at right angle from frons, strongly arched with dorsal surface convex and ventral surface furrowed; lateral margins prolonged basally on frons into raised carinae diverging toward anterior angles of head, just above insertion of mandibles; ventral surface and lateral carinae rimmed by row of short, peg-like denticles, and long, fine, erect setae. Labrum exposed between clypeal carinae, with anterior margin broadly convex and slightly notched medially, posterior margin obscured; dorsal surface coated by long, thin, erect setae. Dorsal margin of mandibles curved dorsally immediately from base, in profile view without distinct elbow, their tips reaching nearby horn's apex, dorsal mandibular margin armed apically as series of sharp, curved teeth; largest apical tooth preceded by two medial teeth of equal length following slight gap; basal portion of mandible (from base to base of medioventral blade) short, simple; distal portion projected medially and ventrally in a large, triangular blade tapering to the tip; the blade with dorsal surface concave, ventral corner rounded, and apical half serrate; tip of mandible with a preapical tooth immediately following the blade and projected posteriorly, and one apical acute tooth curved posteriorly; when mandibles closed, their medial margins parallel and closely approximated, slightly overlapping at ventral corner of blade; accommodated in the triangular clypeal cavity (i.e., concealing the anterior clypeal margin, labrum and ventral surface of horn); maxillary palp with 5 visible segments, labial palp with 3 visible segments.

Mesosoma about twice as long as high. Pronotal colar short, separated from remaining pronotal dorsum by a distinct transverse ridge; pronotum nearly vertical immediately anterior to ridge, feebly convex posterior to ridge (dorsum); posterior pronotal margin with distinct thickening dorsally. Promesonotal suture complete, appears flexible. Mesoscutum shorter than pronotum, mesoscutal dorsal outline faintly convex, with long parapsidal furrows converging posteriorly to reach anterior mesonotal margin. Mesoscutellum prominent; dorsal mesoscutellar surface convex, posterior surface slightly concave, their junction forming a sharp angle. Metanotum medially as high as long, with posterior surface forming distinct angle with propodeal dorsum. Propodeum 1.5 as high as long, dorsal and declivitous surfaces flat, separated by thin ridge, forming sharp angle; propodeal spiracle slit-like atop rounded nodule, situated around junction of propodeal dorsum and sides. Metapleural gland orifice a small circular concavity. Mesopleuron and metapleuron coated in thin, tapered setae. Legs robust, mesocoxa distinctly shorter than pro-and metacoxae, small trochantellus present on mid- and hind legs; all femora moderately swollen in their basal half; ventral margin of protibia apically with large calcar and two straight, stout setae less than half as long as calcar; mesotibia apically with two long, straight, spurs, one pectinate and one simple; additionally with three short stout setae; metatibia apically with one long, pectinate spur, one long, simple spur, and one short, stout seta; tarsomeres IeIV of all legs with pairs of short, stout setae along entire ventral surface (6 pairs on tI, 3 pairs on tII, 3 pairs on tIII, 2 pairs on tIV), and apically with 2 pairs of simple, stout setae each flanking a spatulate seta (
