Material examined (n=1). Holotype ♂: BRAZIL. Amazonas. Lago Amaná, 20.XI.1979, Robin Best leg. ( INPA).

Measurements. Total length: 13.9; head length: 1.6; head width: 2.9; pronotal length: 2.6; pronotal width: 9.0; scutellum length: 6.9; scutellum width: 5.1; abdominal width: 7.7; length of antennal segments. I: 0.9; II: 1.8; III: 1.2; IV: 4.3; V: missing.

Diagnosis. Anterolateral margin of pronotum with solid black stripe along all its extension. Anterolateral margin punctured dorsally. Cicatrices of pronotum with brown punctures delimiting anterior sulci ( Fig. 18K ). Scutellum with anterior margin yellow ( Fig. 18K ). Body ventrally with dark brown stripes ( Fig. 18L ). Male genitalia ( Fig. 6A–D ). Pygophore with dorsal rim almost straight, slightly sinuous ( Fig. 6A ). Superior process of genital cup reniform, rough, gently concave, adjacent to dorsal rim; ventral margin with short digitiform projection ( Fig. 6B–C ); partially visible in dorsal view ( Fig. 6A ). Paramere spatulate or remiform, long, strongly projected laterally; dorsal margin acuminated; anterior and posterior lobes little developed ( Fig. 6B–C ); stalk medially with longitudinal low carina directed toward anterior lobe, but ending far from its apex. Proctiger with dorsolateral tufts of long setae separated by medial high keel; posterior face rounded ( Fig. 6B–D ). Ventral rim medial excavation in “V”; expansion developed, rounded, and surpassing level of posterolateral angles in ventral view; expansions curved ventrally ( Fig. 6B–D ). Female unknown.

Comments. The H. dorsocarinatus has a paramere similar to that of H. nigrosinuatus , H. offuscatus and H. quadridens ( Fig. 6B ; Nunes et al. 2020, Figs. 1A–C , 7A–C ). This paramere has dorsal margin acuminated and anterior and posterior lobes not clearly developed. The central high keel on proctiger is similar to that found in H. quadridens and H. necopinatus ( Nunes et al. 2020, Figs. 1A–C , 6A–C ). Hypoxys dorsocarinatus can be separated from the other species mentioned here by the superior process of the genital cup bigger and paramere longer with posterior lobe more developed ( Fig. 6B–C ).

Etymology. Name refers to the well-developed dorsal carina on proctiger.

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