Material examined (n=2). Holotype ♂: BRAZIL. Amazonas. Tefé, 8.XII.1919, H.S. Parish leg. MNHN( EH) 25124 ( MNHN). Paratype: Same data as holotype: ♀ 27.XII.1919 MNHN( EH) 25120 ( MNHN).

Measurements. Total length: 16–17.1; head length: 1.9–2.0; head width: 3.1–3.2; pronotal length: 3.4–3.5; pronotal width: 10–10.3; scutellum length: 7.5–7.8; scutellum width: 5.8–6.0; abdominal width: 8.6–8.8; length of antennal segments. I: 1.0; II: 2.0–2.1; III: 1.2–1.5; IV: 4.7–5.0; V: missing.

Diagnosis. Anterolateral margin of pronotum with solid black stripe along all of its extension. Anterolateral margin punctured dorsally. Cicatrices of pronotum with black punctures delimiting anterior sulci ( Fig. 20I ). Scutellum with anterior margin concolorous ( Fig. 20I ). Body ventrally with dark brown stripes ( Fig. 20J ). Male genitalia ( Fig. 17A–D ). Pygophore with dorsal rim sinuous, presenting a small median dark, rounded projection ( Fig. 17A ). Superior process of genital cup oblong, narrow, ventral margin with two subtriangular small projections; process contiguous to dorsal rim; visible in dorsal view ( Fig. 17A–C ). Paramere with a large subtriangular and truncated lobe directed anteriorly; posterior lobe short and triangular; inner low carina splitting distally finishing at anterior and posterior apices ( Fig. 17B–C ). Proctiger with laterodorsal tufts of long setae separated by narrow, sparsely setose ridge; posterior face pentagonal, upper part swollen ( Fig. 17A–D ). Expansions of ventral rim acuminated and developed, far exceeding the level of the posterolateral angles in ventral view ( Fig. 17D ). Female ( Fig. 17E ). Valvifers 8 wide, posterior margin sinuous; inner angles rounded and convergent reaching basal part of valvifers 9; inner margins with narrow and elliptic excavation. Valvulae 8 exposed. Valvifers 9 with low medial carina.

Comments. See comments of H. angulatus .

Etymology. Named after the pair of processes on ventral margin of each superior process of genital cup.

Distribution ( Fig. 21B ). BRAZIL: Amazonas.
