Diagnosis

This is a large, relatively robust species with coarse punctation and matt integument. The propodeum is rounded. The male scapi are expanded and the mask is reduced. The female has comma-shaped facial spots and the clypeus has a smooth impression on the front edge. It can be distinguished from H. lightfooti by its size, sculpture and the male terminalia. The male is described here for the first time.

Characteristic features

Male. TL 5.2–5.8 (5.50) mm, WL 3.5–4.1 (3.95) mm.

Head. Proportions HL:HW 0.93, UFW:LFW 1.75; outline short trapezoid. Scapi black, prolonged, expanded medially, wider here than flagella, SL:SW 1.2. Mask white, supraclypeal area often quite black, paraorbital marks reduced, reaching clypeus base, bow-shaped adjacent to orbits. Clypeus CL:CW 1.56, slightly shining, scattered punctate, anterior margin black. Frons and vertex with white pilosity.

Mesosoma compact; tegulae mostly black, sometimes with small pale spot. Pronotum black, expanded forward, anterior edge angular, dorsolateral angles blunt. Mesonotum and scutellum matt, punctation coarse and sparse to dense. Legs black, pale marks at foretibiae in front; wings brownish, venation black. Propodeum rounded, matt, medial area with rough wrinkled meshes, delimited by a carina, terminal area roughly punctate.

Metasoma solid, black. T1 with punctation coarse, dense, apically coarse and subcontiguous, T2 finer and more densely punctate, following terga only shagreen, slightly shining; T1 with narrow white side fringes. Terminalia (Fig. 24): genital capsule short, outline oval, distal lobi of S7 narrower than in H. lightfooti, their comb setae flattened.

Female. TL 5.5–7.0 (6.23) mm, WL 3.8–4.6 (4.27) mm.

Head. Proportions HL:HW 0.94, UFW:LFW 1.48; shape nearly circular. Face with small white comma spots on orbits at height of scapi bases; foveae faciales long. Clypeus CL:CW 1.20, shagreen, matt, punctation strong close, anterior margin with wide smooth impression (Fig. 44), upper margin without tubercles. Frons and vertex with coarse and contiguous punctation.

Mesosoma compact; tegulae with small bright spot. Pronotum black, expanded forward, anterior margin and dorsolateral angles rounded. Mesonotum and scutellum matt, punctation coarse and dense. Legs entirely black; wings darkened, venation dark. Propodeum rounded, matt, roughly punctate, medial area with rough meshes, demarcated by a fine furrow.

Metasoma compact oval, coloration black. T1 with punctation coarse and subcontiguous, especially distally; T2 with finer and more dense punctation, following terga shallowly wrinkled. T1 with narrow white lateral fringes, white narrowly disrupted hair bands on depressions of T2 and T3.
