( Figs 4E–F View Figs 4 , 17A–F View Figs 17 , 21B View Figs 21 )

Material examined. Hඈඅඈඍඒඉൾ: J, BRAZIL: Pൺඋග: Santarém / 30.iv.1931 / C. H. Townsend ( USNM). Pൺඋൺඍඒඉൾ: BRAZIL: Pൺඋග: ♀, same data as holotype except: 17.vi.1931 ( USNM).

Diagnosis. Antennae brown. Antennomere II longer than III. Pronotum with smoky stripe not reaching posterior margin. Thoracic and abdominal pleurites and sternites with black spots ( Fig. 4F View Figs 4 ). Anterior excavation of metasternal process harboring fourth and almost half of third rostral segment ( Fig. 17F View Figs 17 ). Male genitalia. Pygophore ( Figs 17A–D View Figs 17 ). Dorsal rim with small lateral projection rounded close to posterolateral angles ( Fig. 17A View Figs 17 , arrow). Posterolateral angles developed, rounded, and straight ( Fig. 17A View Figs 17 ). Superior process of genital cup parallel to dorsal rim, short, narrow, slightly concave medially; inner (proximal) part truncate, ventral angle with dentiform process; outer (distal) part tongue-like and enlarged, dorsal margin tumid ( Figs 17C,D View Figs 17 ). Paramere with two lobes; both lobes long and rounded distally, resembling whale tail; anterior lobe directed to base of proctiger ( Figs 17C,D View Figs 17 ). Proctiger with tufts of long setae along lateral excavation; posterior face subpentagonal ( Figs 17C,D View Figs 17 ). Ventral rim with expansions triangular, short, distally blunt, inner lateral face not excavated, dorsal side without dark spot; slightly surpassing level of posterolateral angles ( Fig. 17B View Figs 17 ). Female genitalia. Genital plates ( Fig. 17E View Figs 17 ). Valvifers 8 without dentiform angles, posterior margin almost straight, barely slanting; imaginary line tangent to posterior margin not reaching medial line of valvifers 9; excavation V-shaped. Valvulae 8 exposed. Apices of laterotergites 8 above level of apices of abdominal segment VII. Laterotergites 9 surpassing band connecting laterotergites 8; apices almost reaching imaginary line tangent to apices of abdominal segment VII. Measurements (n = 2; holotype first; mm). Total length 12.9 / 14.5; head length 1.3 / 1.6; head width 2.9 / 3.0; pronotum width 8.0 / 8.4; abdomen width 6.5 / 7.2; length of antennomeres: I – 0.8 / 0.9; II – 1.2 / 1.5; III – 1.1 / 1.3; IV – 3.0 / 3.3; V – 3.5 / 3.6; scutellum length 5.7 / 6.3; scutellum width 4.4 / 4.7; pronotum length 2.5 / 2.8.

Differential diagnosis. Considering only the female genitalia, H. santarensis sp. nov. is similar to H. balteatus and H. breddini sp. nov.; see the differential diagnosis of H. balteatus . Considering only the male genitalia, H. santarensis sp. nov. is part of a large group of six species; see differential diagnosis of H. hyalinofasciatus sp. nov.. Etymology. Named after the type locality of the species; adjective.
