Material examined (n=1). Holotype ♂: PERU. Huánuco. Tingo Maria, Monson Valley, 12.X.1954, E.I. Schlinger & E.S. Ross leg. (CAS).

Measurements. Total length: 14.7; head length: 1.9; head width: 2.9; pronotal length: 2.6; pronotal width: 9.4; scutellum length: 7.1; scutellum width: 4.8; abdominal width: 7.5; length of antennal segments. I: 0.9; II: 1.9; III: 1; IV: 3.8; V: 4.4.

Diagnosis. Anterolateral margin of pronotum with solid black stripe along all or part of its extension, when incomplete remaining part smoky black and narrow. Anterolateral margin not punctured dorsally. Cicatrices of pronotum with black punctures delimiting anterior sulci (Fig. 19E). Scutellum with anterior margin with a thin light-yellow line (Fig. 19E). Body ventrally with brown stripes (Fig. 19F). Male genitalia (Fig. 9A–D). Pygophore dorsal rim with a pair of medial black rounded expansions (Fig. 9A). Superior process of genital cup oblique, long, broad, thick, and rugose; adjacent to dorsal rim; visible in dorsal view (Fig. 9A–C). Paramere remiform, short, dorsal margin acuminated medially; anterior and posterior angles triangular; stalk with inner margin carinated, carina curved anteriorly and evanescent distally (Fig. 9B–C). Proctiger with dorsolateral tufts of setae separated by median glabrous bridge; posterior face pentagonal with a medial ridge (Fig. 9A–C). Ventral rim with expansions rounded, small, slightly surpassing levels of posterolateral angles in ventral view (Fig. 9D). Female unknown.

Comments. This specie is unique due to the shape of the superior process of the genital cup and paramere short (Fig. 9B–C). The paramere is somehow comparable with that of H. dorsocarinatus, H. nigrosinuatus, H. offuscatus and H. quadridens (see comments of H. dorsocarinatus).

Etymology. Name refers to the black rounded mesial projections on dorsal rim.
