Occipital foramen positioned highly dorsad, just under vertex of head. Postgena broadly depressed; postgenal suture visible, deeply furrowed. Vertex broadly rounded and glabrous with gena gradually tapered ventrally towards mandibular socket and oral opening with fine, sparse setae. Ocelli faintly visible on vertex, positioned dorsally. Eye situated high on head capsule and bulging in frontal view, ovoid, measuring 0.38 mm in length and 0.25 mm in width when viewed laterally. Three antennal segments fully preserved (scape 0.94 mm in length; pedicel 0.12 mm; flagellomere I 0.55 mm). Antennal socket approximately in line with ventral margin of eye; socket exposed and immediately flanking a medial frontal triangle (

). Frontal triangle extends the vertex, contrasted with antennal sockets, which are present within cuticular depressions. Clypeal horn originating at both frontal triangle and clypeal stalk, both structures heavily sclerotized with cleared, membrane-like cuticle connecting from frontal triangle to stalk. Horn paddle-shaped, total length 0.64 mm, diameter 0.49 at greatest; narrow (0.04 mm) glabrous stalk 0.22 mm in length leading to setose pad; setose pad (0.42 in length) with long trigger hairs originating at pad base; dorsal margin of setose pad glabrous, underside coated in a large number of stout setae in centre and longer, more tapered setae along edges. Anterior margin of clypeus medially triangulate; distinct medial ridge extending to clypeal horn; lateral margins, beginning just above mandibular insertion, extending diagonally toward clypeal horn. Cheek-like lobes projecting anteroventrally above mandible insertion. Mandible scythe-like, comprise a linear basal margin (0.55 mm in length) and curved apical tooth (0.92 mm measured as a straight line from base to tip, ignoring curvature) meeting nearly at right angle; preserved with apical teeth in parallel, nearly touching. Basal portion of mandible with anterior flange-like expansion, concave inner margin coated with pointed setae; leading edge of anterior flange expansion smooth; apical tooth rounded broadly with slight point. Maxillary and labial palps not visible.

Petiole 0.49 mm in length, 0.49 mm in height at greatest, pedunculate; not tergosternally fused, deep suture visible; anterior margin gradually sloping; with gradually rounded dorsal margin; broadly attached to gastral segment I (abd seg III) with striated helcium clearly visible. Lateral sulcus visible running anteroposteriorly along petiole, signifying incomplete fusion; ventral to sulcus lies thin, membraneous cuticular expansion with distinct anteriorly positioned keel. Sternite III with pointed projection on anterior margin exhibiting striations running laterally. Circumgastral constriction present between gastral segments I and II with dorsal, posteriorly extended notch. Gastral cuticle translucent, revealing heavily sclerotized and expanded apodemes of gastral sternites IV and V withdrawn into the gaster.

These three specimens probably represent additional species, particularly with respect to overall size and clypeal paddle composition. Moreover, these specimens possess mandibles that appear to interlock basally, joining the distal apical tooth portions of the mouthparts (
