Material examined (n=1). Holotype ♂: BRAZIL. Amazonas. R. [river] Itacoaí, V.50, J.C.M Carvalho leg. ( MNRJ).

Measurements. Total length: 15.5; head length: 2.2; head width: 3.0; pronotal length: 2.7; pronotal width: 9.5; scutellum length: 7.6; scutellum width: 5.4; abdominal width: 8.4; length of antennal segments. I: 1.0; II: 1.9; III: 1.4; IV: 4.7; 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. 18A ). Scutellum with anterior margin yellow ( Fig. 18A ). Body ventrally with dark lines faded ( Fig. 18B ). Male genitalia ( Fig. 1A–D ). Dorsal rim of the pygophore with two slightly rounded expansions ( Fig. 1A ). Superior process of genital cup elongated, curved ventrally; ventral margin with a medial small rounded process; adjacent to dorsal rim; visible in dorsal view ( Fig. 1A–C ). Paramere triangular; anterior lobe short and truncated, posterior lobe developed and triangular; stalk with a medial inner carina reaching apex of anterior lobe; posterior lobe carinated ( Fig. 1B–C ). Proctiger with dorsolateral dense tufts of long setae separated by median flat slightly rugose area with sparse setae; posterior face barrel-shaped ( Fig. 1A–D ). Ventral rim median excavation deep and emarginated; expansions arched, large, with inner right angles, and surpassing level of posterolateral angles in ventral view ( Fig. 1D ). Female unknown.

Comments. This species belongs to the group with triangular paramere, together with H. ventrotuberculatus sp. n. ( Figs. 17B ). The H. angulatus has the anterior lobe of the paramere short (long in H. ventrotuberculatus ) and posterior lobe long (short in H. ventrotuberculatus ); also superior process of the genital cup with a short process in ventral margin (two processes in H. ventrotuberculatus , Fig. 17B ).

Etymology. A reference to the angular shape of the dorsal margin of the superior process of genital cup and inner angles of the expansions of the ventral rim of the pygophore.

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