Material examined (n=6). Holotype ♂: FRENCH GUIANA. Saint-Laurent du Maroni, in september, Le Moult leg. (MNHN). Paratypes: FRENCH GUIANA. ♂ Pont de la Comté, RN2, 20.IX.1998 R. Lupoli leg. (RLC); COLOMBIA. Meta: ♀ Vista Hermosa, 28-30.XI.1970, M. Descamps leg. (MNHN); BRAZIL. Pará: ♂ Belém, Parque do Utinga, 10.X.1962, J. Bechyné leg. (MZUSP). BOLIVIA. Santa Cruz: ♀ 339, 8599/34 (both number on different faces of the same label) [Santa Cruz de la Sierra province, November 1830] MNHN(EH) 25122 (MNHN); No data: ♂ MNHN(EH) 25123 (MNHN).
Measurements. Total length: 15.5–16.3; head length: 1.5–2.0; head width: 3.9–3.2; pronotal length: 3.0–3.2; pronotal width: 9.1–10.0; abdominal width: 8.5–8.7; scutellum length: 6.7–7.5; scutellum width: 5.4–5.6; length of antennal segments. I: 0.9–1.0; II: 2.0–3.4; III: 1.0–1.3; IV: 4.0–4.4; V: 4.5–5.7.
Diagnosis. Anterolateral margin of pronotum with solid black stripe along half of its extension, remaining smoky black. Anterolateral margin with few dark punctures dorsally (Fig. 18G). Cicatrices with dark brown punctures delimiting anterior sulci (Fig. 18G). Scutellum with anterior margin concolorous (Fig. 18G). Body ventrally with stripes dark brown (Fig. 18H). Male genitalia (Fig. 4A–D). Pygophore with dorsal rim shallowly excavated (Fig. 4A). Superior process of genital cup small, reniform, ventral margin with a short medial digitiform projection, adjacent to dorsal rim; visible in dorsal view (Fig. 4A–C). Head of the paramere broad; anterior lobe short and truncated; posterior lobe large and acuminated; stalk with a low ridge on inner face evanescent toward anterior lobe (Fig. 4B–C). Proctiger with dorsolateral dense tufts of long setae separated by median wide glabrous area; posterior face barrel-shaped (Fig. 4B–D). Ventral rim with medial excavation in “V”, margin swollen; expansions large, broad, rounded, distally light yellow, surpassing level of posterolateral angles in ventral view (Fig. 4D). Female unknown.
Comments. The number 8599/34 attached to the paratype female deposited in the collection of MNHN means entry n° 8599 of the year 1834 on the catalogue d’Orbigny (1834) with the following information: “ Bolivie, province Santa Cruz de la Sierra, punaise sur buissons et arbustes à la lisière de bois épais et humides, vole facilement sur plantes cultivées, novembre 1830 ” [Bolivia, Santa Cruz de la Sierra province, bug on bushes and shrubs at the edge of thick, damp woods, flies easily on cultivated plants, November 1830]. This species like H. unguiculatus and H. runcinatus shows the head of the paramere broad with posterior lobe well-developed and rounded to acuminated, anterior lobe somewhat developed and rounded (Figs. 4B, 16B, 13B). The species H. crassimarginatum can be separated from the other two by the anterior lobe of the paramere slightly developed (Fig. 4B) (more developed in H. unguiculatus and H. runcinatus (Figs. 16B, 13B); and superior process of the genital cup curved ventrally (Fig. 4B) (almost straight in H. unguiculatus and H. runcinatus).
Etymology. Name refers to the swollen margin of the median excavation of ventral rim of the pygophore (crassus = thick, stout).
Distribution (Fig. 21A). FRENCH GUIANA: Saint-Laurent du Maroni; COLOMBIA: Meta; BRAZIL: Pará; BOLIVIA: Santa Cruz.
