Material examined (n=8). Holotype ♂: BRAZIL. Amazonas. Uypiranga, Rio Negro, Pko 15.X–15.XII.1941 (MNRJ). Paratypes: BRAZIL. Pará: ♂ Óbidos, VI.7.1929, via H. Rolle (USNM); Amazonas: ♂ Manaus, IX.1959, Elias e Roppa leg. (MNRJ); ♂ Manaus, Est. Am 1. Km 64, 21.VIII.1970, A. Faustino leg. (INPA); ♀ same data holotype (MNRJ); same data: ♀ 20–30/X.1941 (MNRJ); ♂ ♀ Manacapuru S.A, Solimões River, IV.1928, S.M. Klages leg. (KSEM).
Measurements. Total length: 14.5–15.4; head length: 1.4–2.0; head width: 3.1–3.5; pronotal length: 2.5–2.9; pronotal width: 8.9–9.5.3; scutellum length: 6.7–7.4; scutellum width: 5.0–5.5; abdominal width: 8.0–8.7; length of antennal segments. I: 1.0; II: 1.1–2.0; III: 1.2–2.9; IV: 4.2–4.4; 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. 18E). Scutellum with anterior margin yellow (Fig. 18E). Body ventrally with brown lines (Fig. 18F). Male (Fig. 3A–D). Pygophore with lateral sides somewhat excavated (Fig. 3C–D). Dorsal rim with a small median excavation at the base of the proctiger (Fig. 3A). Superior process of genital cup laminar, thick, rounded distally, with a small step at the base, and adjacent to dorsal rim; visible in dorsal view (Fig. 3A–C). Paramere elongated, club-like, strongly bent laterally; inner margin with conspicuous carina ending at the apex of the posterior lobe; posterior lobe large and acuminated distally; anterior lobe rounded and barely developed; stalk conspicuously carinated (Fig. 3A–C). Proctiger with tufts of dense and long setae along lateral margins separated dorsally by barely visible bridge; posterior face pentagonal (Fig. 3B,C). Ventral rim projected posteriorly, median excavation widely open and shallow; expansions well-developed, narrow, rounded, slightly curved laterally, surpassing level of posterolateral angles in ventral view; strongly setose on apex (Fig. 3D). Female (Fig. 3E). Valvifers 8 slightly convex, posterior margin arched; inner angle reaching half of valvifers 9; inner margins divergent in distal half; margin dark brown. Valvulae 8 partially exposed.
Comments. This species resembles H. cristatus because only these two species have paramere with posterior lobe developed and oblong and superior process of genital cup laminar and oblique to the sagittal plane (Figs. 3B–C, 5B–C). H. clavatum has the head of the paramere larger than H. cristatus (Figs. 3B–C, 5B–C). Also, H. clavatum has the superior process of the genital cup narrower and smaller than H. cristatus. These two species also belong to the large group of species with paramere golf club like (Figs. 3B, 5B).
Etymology. Name refers to the golf club-like shape of the paramere (crassus = thick, stout).
Distribution (Fig. 21A). BRAZIL: Amazonas, Pará.
