Distribution | Mexico (San Luis Potosí) Type locality: Tamul waterfall, 4.4 km SW from the locality of Tanchachín, municipality of Aquismón, San Luis Potosí, Mexico (21.804°, -99.180°; 195 m elev.) |
Reproduction | Viviparous. Mating season is unknown, but probably occurs at the end of the rainy season, like other Lepidophyma species (Méndez de la Cruz et al. 1999). Five females gave birth in captivity a total of 16 neonates between 2nd to 13th June of 2019. The minimum SVL of pregnant females was 45 mm. The mean litter size was 3.2 ± 1.48 neonates (range: 1–5). Neonates had a mean SVL of 22.6 ± 0.88 mm (range: 21–24 mm) and a mean mass of 0.22 ± 0.02 g (range: 0.17–0.27 g). The mean relative litter mass (RLM), according to the method described by Rodríguez-Romero et al. (2005; RLM = litter mass/mass of female after parturition), was 0.3940 ± 0.1549 g (range: 0.1541–0.4405 g). |
Types | Holotype: CNAR IBH 32556, adult female, collected by Arenas-Moreno, D.M., Bautista-del Moral A., and Rodríguez-Miranda L.A. on 2nd May 2020. Paratypes (n = 11): CNAR IBH, 32554-55, 32557-65, collected by Arenas-Moreno, D.M., Bautista-del Moral A., and Rodríguez-Miranda L.A. on 2nd May 2020 |
Diagnosis | Diagnosis: Lepidophyma lusca sp. nov. can be distinguished from all congeners by the following combination of characters: smooth scales with reduced dorsal tubercules; absence of parietal spot; up to 38 gular scales; more than one gular scale contacting the first two infralabials in some individuals; caudal interwhorls not complete ventrally; less than 137 dorsal scales; 26 or less femoral pores (Arenas-Moreno et al. 2021). Additional details (1952 characters) are available for collaborators and contributors. Please contact us for details. |
Comment | Diet: Fecal analysis of individuals collected shows that L. lusca sp. nov. is insectivorous like other night lizard species (Bezy & Camarillo 2002; Arenas-Moreno et al. 2021). Similar species: L. gaigeae. |
Etymology | The specific epithet, “lusca”, is the singular feminine noun in Latin for “one eyed”, due the absence of parietal eye. |
