Diagnosis

Females with dark mesoscutum and pairs of dorsolateral yellow maculations on the terga, connected by a basal line in T2. Differs from those of similar species by the metasomal maculations, absent in H. beatissimus , and by the areolate mesoscutum disc, not granular as in H. ligeus .

Males with metapostnotum surface elevated in relation to the propodeum, especially posteriorly, and with yellow maculations on the metasoma. The mesoscutum anterior margin is acuminate-shaped, not rounded as H. callichroma . Pronotal dorsolateral angle acute, not obtuse as H. obscuratus sp. nov. The anterior portion of the median line of the mesoscutum is more strongly lineolate than H. beatissimus .

Terga clavate form (about the same width, apex more dilated); dark brown with yellow maculations, as follows: T2–T4 with yellow basal bands, sometimes hidden by the terga looking like separate maculations; covered with short decumbent setae very sparsely distributed in T1, which progressively become denser towards T6; lineolate. S5 without any projection.

GENITALIA. Gonobase at least three times shorter than the gonocoxite, with basal projection. Gonocoxite elongate, basal portion of the dorsal inner margin forming a sinuose flange. Gonapophysis slender, apex weakly rounded, longer than the gonostylus, curved ventrally. Gonostylus basal lobe elongated, with short setae; ventral process C-shaped, with small setae elsewhere and long setae apically, dorsal process expanded apically. Volsella developed.

MEASUREMENTS. Approximate body length 5.92 mm. Head mean width 1.25 mm. Head mean length 1.16 mm. Clypeoantennal mean distance 0.27 mm. Mean distance between subantennal sutures 0.3 mm.
