Material examined (n=5). Holotype ♂: PERU. Amazonas. Rio Santiago , 20.XI.1924, H. Bassler leg. ( USNM) . Paratypes: PERU. Iquitos: ♂ Rio Maranon , 7.XI.1927, H. Bassler leg. ( USNM) ; ♀ Amazon River , 21.II.1927, H. Bassler leg. ( USNM) ; Amazonas: 1 specimen without abdomen, same data holotype ( USNM) ; same data : ♀ 27.XI.1924 ( USNM) .

Measurements. Total length: 14.7–17.2; head length: 1.8–1.9; head width: 3.1–3.3; pronotal length: 2.6–2.9; pronotal width: 9.0–10.2; scutellum length: 7.2–8.1; scutellum width: 5.0–5.7; abdominal width: 8.2–9.3; length of antennal segments. I: 0.9–1.0; II: 2.0–2.2; III: 1.2–1.5; IV: 4.7–5.0; V: missing.

Diagnosis. Anterolateral margin of pronotum with solid black stripe along all its extension. Anterolateral margin punctured dorsally. Cicatrices of pronotum with black punctures delimiting anterior sulci ( Fig. 19C ). Scutellum with anterior margin yellow ( Fig. 19C ). Body ventrally with stripes dark brown ( Fig. 19D ). Male genitalia ( Fig. 8A–D ). Pygophore with dorsal rim excavated ( Fig. 8A ). Superior process of genital cup subrectangular with both ends rounded; close to dorsal rim; visible in dorsal view ( Fig. 8A–C ). Paramere sinuous, twisted; anterior lobe digitiform, dorsally projected ( Fig. 8A–C ); posterior lobe almost inconspicuous; stalk with inner face carinated, carina ending at the apex of anterior lobe ( Fig. 8B–C ). Proctiger with dorsolateral dense tufts of long setae separated by an almost glabrous broad bridge; posterior face somewhat swollen, barrel-shaped ( Fig. 8A–D ). Ventral rim median excavation in “V”; expansions well-developed, large, acuminated, surpassing level of posterolateral angles in ventral view ( Fig. 8D ). Female genitalia ( Fig. 8E ). Valvifers 8 subtrapezoidal; posterior margin almost straight and sloping; inner angle rounded and projected over valvifers 9; inner margins dark with small, distal, bottle-shaped excavation. Valvulae 9 barely exposed.

Comments. The male genitalia of H. flexuosus resembles H. dolosus and H. eburatulus ( Nunes et al. 2020, Figs. 4B , 5B ) because paramere has anterior lobe long and curved dorsally and posterior lobe not developed; superior process of genital cup squared; and posterior face of proctiger somewhat swollen ( Fig. 8B–C ). But H. flexuosus differ from both by paramere twisted and superior process of genital cup subrectangular ( Fig. 8B–C ). Female genitalia of H. flexuosus , on the other hand, is not similar to H. dolosus or H. eburatulus , but similar to H. excavatus , H. boerneri and other species with valvifers 8 with medial excavation elliptical ( Figs. 8E , 7E ).

Etymology. Name refers to the sinuous parameres ( flexuosus =full of bends).

Distribution ( Fig. 21A ). PERU: Iquitos, Amazonas.
