| Diagnosis | Diagnosis (genus): Habrophallos is a small leptotyphlopid snake genus characterized by the following unique combination of characters: hemipenis unilobed, with two flattened areas (one basal and another on the apex); hemipenis with a large lateral flounce with folding at one side and a hook‐shaped process on the other side; apex of the hemipenis with a double projection lateroprox‐ imally oriented; skull with paired nasal bones; parietal bone not fused to any other skull element; parietal fontanelle absent, in‐ ternal pillars of parietal bone present; supraoccipitals fused into a single unit, moderate statolithic mass present in cavum vestibuli, otooccipitals prevent the basioccipital on forming the foramen magnum; distinct eye; midbody scale rows 14, midtail scale rows 10; 151–163 middorsal scales, 13–15 subcaudals, 1 + 1 supralabi‐ als; 92–120 mm maximum total length in adults, a body shape of 31–41 (total length/width), a relative tail length of 8.5%–9.7%, a relation of tail length/diameter of 3.3–4.7; supraocular scale present; terminal spine present; no striped pattern (although some lighter pigmentation in the tip of scales might suggest a striped pattern), brown dorsal color, and light brown venter; yellow blotch on rostral region present; ultimate part of tail including spine yellow; yellow nuchal collar present. |
| Comment | Type species: Habrophallos collaris (Hoogmoed, 1977) is the type species of the genus Habrophallos MARTINS et al. 2020. Distribution: see map in Hoogmoed and Lima (2018). See map in Nogueira et al. 2019. |
| Etymology | The species is named after the Latin word collaris meaning collar (Lemos-Espinal & Dixon 2013). The generic name is derived from the Greek “habros” (pretty, graceful, delicate) + the Greek “phallos,” used herein in reference to the small, delicate, and diagnostic hemipenial morphology of the new genus. |
