Material examined (n=1). Holotype ♂: COLOMBIA. Meta. Rio Negro, finca near Villavivencio, 5.II.69, R.E. Dietz IV leg. (USNM).
Measurements. Total length: 15.5; head length: 1.6; head width: 3.0; pronotal length: 3.0; pronotal width: 9.0; scutellum length: 7.2; scutellum width: 5.3; abdominal width: 8.0; length of antennal segments. I: 0.9; II: 1.7; III: 1.0; IV: 4.0; V: 4.5.
Diagnosis. Anterolateral margin of pronotum with solid black stripe along part of its extension. Anterolateral margin dorsally weakly punctured. Cicatrices of pronotum with punctures brown and concolorous delimiting anterior sulci (Fig. 18C). Posterior part of pronotum with a somewhat faded black stripe (Fig. 18C). Anterior margin of scutellum greenish yellow (Fig. 18C). Body ventrally with dark lines (Fig. 18D). Male genitalia (Fig. 2A–D). Pygophore with dorsal rim rugose and shallowly excavated (Fig. 2A). Dorsal surface with two swollen conspicuous lateral areas adjacent to dorsal rim (Fig. 2A). Superior process of genital cup reniform, medially concave, brown and adjacent to dorsal rim; not visible in dorsal view (Fig. 2A–C). Parameres elongated, golf club shaped, laterally curved; anterior lobe very short and rounded; posterior lobe developed and subtriangular; inner face of the stalk with a high carina ending at the apex of posterior lobe (Fig. 2B–C). Proctiger strongly compressed laterally with dorsolateral tufts of long setae separated by a median bridge without setae; posterior face barrel-shaped (Fig. 2B–D). Ventral rim with median excavation “V” shaped, margin slightly sloping ventrally; expansions not developed, rounded, almost level with posterolateral angles in ventral view (Fig. 2B–D). Female unknown.
Comments. This species has the posterior stripe of pronotum slightly faded (Fig. 18C), unlike the rest of the species of the quadridens group. This species belongs to the group of species with paramere with posterior lobe well-developed and anterior lobe barely developed, like a golf club (Fig. 2B–C). This group gathers nine species that can be separated by the shape of the paramere and superior process of genital cup. The species H. bitumidus belongs to the group with superior process of the genital cup oblong and curved (Fig. 2B–C) together with H. similis (Fig. 14B–C). Both species have posterior lobe of the paramere triangular and anterior lobe rounded and barely developed (Figs. 2B, 14B). But these species can be separated by the pair of swollen areas close to dorsal rim (Fig. 2A), posterior face of the proctiger barrel-shaped (Fig. 2B,D) and expansions of ventral rim barely developed (Fig. 2D) in H. bitumidus (without pair of swollen areas, posterior face pentagonal and expansions of ventral rim strongly developed in H. similis).
Etymology. Name refers to the tumid lateral areas on dorsal rim of the pygophore.
Distribution (Fig. 21B). COLOMBIA: Meta.
