Hypoxys angulatus Nunes & Mendonça & Fernandes 2022, sp. n

Hypoxys angulatus sp. n. (Figures 1A–D, 18A–B, 21A) http://zoobank.org/ urn:lsid:zoobank.org:act: A68C1903-7754-4A06-96A9-4D413BEAFBF2 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.
