Material examined (n=2). Holotype ♂: PERU. Loreto. Exploronapo Camp on R. [river] Sucusari nr. [near] R. [river] Napo, 12-19.III.1988, J.E. Eger leg.(JEE). Paratype: PERU. Iquitos: ♀ Quistococha, 21.IV.1984, Ryan Richards leg. (USNM).
Measurements. Total length: 14.6–14.7; head length: 1.4–1.5; head width: 2.9–3.0; pronotal width: 8.4–8.7; abdominal width: 7.2–7.9; length of antennal segments. I: 0.9–0.9; II: 1.6–1.7; III: 1.4–1.4; IV: 4.0–4.4; V: 4.5–0.0; interocular distance: 1.2–1.7; scutellum length: 6.7–6.9; scutellum width: 4.9–5.0; pronotal length: 2.7–2.8.
Diagnosis. Anterolateral margin of pronotum with solid black stripe reaching all its extension. Anterolateral margin with some brown punctures dorsally. Cicatrices with dark brown punctures delimiting anterior sulci (Fig. 20E). Body ventrally with brown stripes (Fig. 20F). Male (Fig. 15A–D). Pygophore with dorsal rim sinuous (Fig. 15A). Superior process of genital cup with distal part rounded, thick and medially concave, proximal part widely bifid; process next to dorsal rim; visible in dorsal view (Fig. 15A–C). Paramere with an elongated lobe dorsally directed, apex rounded; posterior lobe short and triangular; inner low carina splitting distally finishing at anterior and posterior apices (Fig. 15B–C). Proctiger with dorsal tufts of short setae separated by sparsely setose ridge; posterior face pentagonal (Fig. 15A–C). Ventral rim with expansions acuminated, yellow, clearly surpassing level of posterolateral angles in ventral view (Fig. 15D). Female (Fig. 15E). Valvifers 8 with posterior margin sinuous and distally truncate over valvifers 9; lateral margin depressed; inner margin dark and deeply excavated, U-shaped. Valvulae 8 widely exposed.
Comments. The paramere of H. trilobulatus resembles H. dolosus, H. eburatulus, and H. flexuosus because anterior lobe is developed and directed dorsally (Figs. 15B, 8B; Nunes et al. 2020, Figs. 4B, 5B). But H. trilobulatus has trilobulate superior process of the genital cup (without lobes in the others). Also, posterior lobe of the paramere is slightly developed and triangular in H. trilobulatus (rounded and barely developed in the others). The female of H. trilobulatus has the excavation of inner margins of valvifers 8 deep and cup-shaped (Fig. 15E), meanwhile H. dolosus and H. eburatulus have a V-shaped excavation (Nunes et al. 2020, Figs. 4D, 5D) and H. flexuosus a very small bottle-shaped excavation (Fig. 8E).
Etymology. Species named for the three lobes of the superior process of genital cup.
Distribution (Fig. 21B). PERU: Loreto, Iquitos.
