Hypoxys venustus sp. nov.

( Figs 5E–F , 20A–E , 21A )

Material examined. Hඈඅඈඍඒඉൾ: J, BOLIVIA: CඈർΗൺൻൺආൻൺ: Villa Tunari, Chapare / ii.1992 / G. Castillo leg. ( USNM).

Diagnosis. Antennae reddish. Antennomere II longer than III. Pronotum with smoky stripe reaching posterior margin. Thoracic and abdominal pleurites and sternites with black spots ( Fig. 5F ). Anterior excavation of metasternal process harboring fourth and third rostral segment ( Fig. 20E ). Male genitalia. Pygophore ( Figs 20A–D ). Posterolateral angles developed, straight, rounded ( Fig. 20A ) not reaching level of projections of ventral rim ( Fig. 20B ). Superior process of genital cup parallel to dorsal rim, long, reaching posterolateral angles, slightly concave medially; inner (proximal) part truncate, ventral angle projected in dentiform process, adjacent to this angle emerges carina almost parallel to this process; outer (distal) part tonguelike ( Figs 20C,D ). Paramere with two lobes; anterior lobe triangular, developed, and directed to base of proctiger; lateral and dorsal lobes short and rounded ( Figs 20C,D ). Proctiger with tufts of short setae along lateral excavation; posterior face triangular ( Figs 20C,D ). Ventral rim with expansion triangular, distally blunt, ventrolateral side with broad striated excavation, dorsal side without brown spot; apices clearly surpassing level of posterolateral angle ( Fig. 20B ). Female genitalia. Unknown.

Measurements (n = 1; mm). Total length 17.8; head length 1.8; head width 3.5; pronotum width 11.7; abdomen width 9.0; length of antennomeres: I – 0.9; II – 1.7; III – 1.6; IV – 4.3; V: missing; scutellum length 7.6; scutellum width 6.3; pronotum length 3.5.

Differential diagnosis. See differential diagnosis of H. hyalinofasciatus sp. nov.
