Diagnosis

Male is characterized by a unique feature in the subgenus, namely the gonoforcipes with stylus-shaped extensions. The female has three yellow lines on the face. The sculpture, in both sexes, is similar to H. rugipunctus , but the tergal punctation is somewhat finer. The male is described here for the first time.

Characteristic features

Male. TL 4.3–5.1 (4.77) mm, WL 3.0–3.7 (3.43) mm.

Head. Proportions HL:HW 0.95, UFW:LFW 1.94; outline transversely trapezoid. Scapi black, short, not expanded, SL:SW 2.0; flagella long, yellow, dark above. Mask light yellow, supraclypeal area mostly black, sometimes narrowly yellow below. Clypeus matt, CI 1.47, with scattered punctation, anterior margin black. Frons and vertex densely and shallowly punctate.

Mesosoma. Bright: pronotum with yellow line split medially, calli and tegulae yellow spotted. Pronotum narrowly expanded forward; anterior margin with sharp edge medially, dorsolateral angles edged. Mesonotum and scutellum with strong dense to close punctation, punctures irregular, shallow. Legs black, with bright patches on base of tibiae, on foretibiae in front and on basitarsi. Propodeum edged, horizontal part short; medial area with coarse, shiny net meshes, delimited by a carina; terminal area sharply edged below, mid furrow shallow.

Metasoma stocky spindle-shaped; black. T1 shagreen, matt, punctation moderately dense, T2 with fine dense punctation, following terga with indistinct punctation disappearing in sculpture; T1 with narrow white lateral fringes. Terminalia (Fig. 27): genital capsule characterized by gonoforcipes with stylus-shaped appendage, S8 compact, S7 without comb teeth, similar H. rugipunctus .

Female. TL 5.3–6.1 (5.72) mm, WL 3.9–4.9 (4.21) mm.

Head. Proportions HL:HW 0.93, UFW:LFW 1.70; outline rounded trapezoidal. Face with long light yellow stripes along orbits, from lower eye rim to near foveae, also on clypeus a medial longitudinal line. Clypeus matt, punctures large but shallow, CL:CW 1.31; foveae faciales long.

Mesosoma. Pronotum with a narrow yellow band, calli and tegulae spotted. Pronotum narrowly expanded forward, edgy sharp in middle, dorsolateral angles blunt. Mesonotum and scutellum slightly shining, punctation strong and dense, punctures shallow ( Fig. 35 ). Legs black, bright patches only on front surface of foretibiae; wings darkened, venation brown. Horizontal part of propodeum short, medial area with coarse wrinkles, apically delimited by a carina, terminal area with sharp edge only below, surface area rugose.

Metasoma compact oval; black. T1 shagreen, punctation fine and close; following terga with indistinct punctures in shagreen; T1 with narrow white lateral fringes, depressions of following terga with broadly interrupted white hair bands.
