Material examined (n=1). Holotype ♂: PERU. Cuzco. Santa Isabel, Valley of River Cosnipata , 20.XI.1951, F. Woytkowski leg. ( USNM).

Measurements. Total length: 14.4; head length: 1.8; head width: 2.9; pronotal length: 2.5; pronotal width: 8.6; scutellum length: 7.1; scutellum width: 4.8; abdominal width: 7.9; length of antennal segments. I: 0.7; II: 1.8; III: 1.1; IV: 3.8; V: missing.

Diagnosis. Anterolateral margin of pronotum with solid black stripe along less than half of its extension. Anterolateral margin not punctured dorsally. Cicatrices of pronotum with concolorous punctures delimiting anterior sulci ( Fig. 19G ). Scutellum with anterior margin concolorous ( Fig. 19G ). Body ventrally with brown stripes ( Fig. 19H ). Male genitalia ( Fig. 10A–D ). Pygophore strongly excavated laterally, leaving visible base of the paramere and superior process of the genital cup ( Fig. 10C–D ). Dorsal rim strongly projected medially around base of proctiger; lateral angles strongly projected posteriorly, covering posterolateral angles in dorsal view ( Fig. 10A ). Superior process of genital cup half-moon shaped and concave; apex reaching dorsal rim; partially visible in dorsal view ( Fig. 10A–C ). Paramere long, dorsally directed; anterior lobe broadly expanded dorsally and rounded; posterior lobe short and triangular; inner face of the stalk with low evanescent carina curved to anterior lobe ( Fig. 10A–C ). Proctiger with dorsolateral tufts of short setae separated by broad glabrous bridge; posterior face projected caudally and ventrally, surpassing ventral rim, resembling Greek letter Omega ( Fig. 10B–C ). Ventral rim projected caudally, medial excavation shallow; expansions long, narrow, apex rounded, densely setose; surpassing level of posterolateral angles in ventral view ( Fig. 10D ). Female unknown.

Comments. This species resembles Hypoxys boerneri and H. excavatus (see comments of H. excavatus ). However, this species is very different from all other species in the genus. This species has a dorsal rim very projected caudally, specially the corners; the paramere and posterior face of the proctiger are remarkable ( Fig. 10B,C ); and ventral rim is clearly different from H. boerneri and H. excavatus ( Figs. 7D , 10D ).

Etymology. Name refers to the posterior face of proctiger resembling the Greek Omega letter (Suf. - oides: resembling, having the form of).

Distribution ( Fig. 21B ). PERU: Cuzco.
