( Figures 12A–E , 19K–L , 21A ) http://zoobank.org/ urn:lsid:zoobank.org:act: C80095A6-AD28-4782-B04A-350ADB3BB79F Material examined (n=3). Holotype ♂ : BRAZIL . Amazonas .

Total length: 15.5–15.8; head length: 1.5–1.8; head width: 3.0–3.2; pronotal width: 8.9–9.8; abdominal width: 7.9–8.7; length of antennal segments.

Hypoxys pentagonalis sp. n. A–D Male, pygophore; A—dorsal view; B—posterior view; C—lateroposterior view; D—ventral view. E—Female, genital plates (Scale = 1mm). Diagnosis. Anterolateral margin of pronotum with complete solid black stripe. Anterolateral margin with black punctures dorsally. Cicatrices with black punctures delimiting anterior sulci ( Fig. 19K ). Scutellum with anterior margin yellow ( Fig. 19K ). Body ventrally with dark brown stripes ( Fig. 19L ). Male genitalia ( Fig. 12A–D ). Pygophore dorsal rim shallowly excavated ( Fig. 12A ). Superior process of genital cup half-moon shaped, inner angle acute, ventral margin with developed median triangular projection; touching dorsal rim; visible in dorsal view ( Fig. 12A–C ). Paramere club-like, elongated, laterally bent, margin black; anterior lobe slightly developed and rounded; posterior lobe narrow and truncated; inner face of the stalk with tiny carina ending before bent part ( Fig. 12B–C ). Proctiger with dorsolateral tufts of long setae separated by dorsal narrow ridge; posterior face longer than wide, basal half rugulose with a central fold, ventral margin biconvex ( Fig. 12A–D ). Ventral rim with median excavation in “U”; expansions setose, rounded, wide, surpassing level of posterolateral angles in ventral view ( Fig. 12D ). Female genitalia ( Fig. 12E ). Valvifers 8 with posterior margin slightly sinuous, inner angles acuminated to rounded, reaching base of valvifers 9; an almost distal fold hides posterior margin in ventral view; inner margins dark, divergent on distal 2/3, median excavation cup like. Valvulae 9 exposed. Comments. This species shows the lateral margins of the posterior face remarkably projected ventrally. Only H. omegoides has the proctiger projected ventrally, but in a completely different way; also other parts of the pygophore separate them ( Figs. 12A–D , 10A–D ). Female has the genital plates similar to H. flexuosus and several species with elliptical median excavation of the valvifers 8, but the fold adjacent to posterior margin can separate them. Etymology. Name refers to the rugulose basal half of the posterior surface of proctiger. Distribution ( Fig. 21A ). BRAZIL : Amazonas.
