Diagnosis | Diagnosis (genus): A member of Sphenomorphus group of lygosomine scincids and a derived member of the variegatus species-group (sensu Greer, 1974; 1979) showing similarities to the primarily Asian Scincella-like and Ablepharus-like species groups (genera: Asymblepharus and Scincella [sensu Eremchenko, 1987]), but differing from them in having the following combination of characters: A). Group II alpha palate (sensu Greer, 1974); lower eyelid with a clear window; nuchals and Group I temporal scales (Greer, 1974); two frontoparietals, or frontoparietal single; prefrontals small and separated; tympanum slightly or deeply sunk; limbs well-developed; scales around midbody 20-30; and middle neck and dorsum 26-41; four enlarged preanals, central pair larger than lateral pair. B). premaxillary teeth nine; pterygoid teeth rudimentary, 0-5; postorbitals present, elongated, thin; greater part of dorsal surface of digits with 1-2 rows of scales (Fig. 2) sharing characters with Group I and III (sensu Brongersma, 1942: Fig. 1b-d) fifth and sixth supralabial in midorbital position; size small, SVL to 62.0 mm; tail bright blue [EREMCHENKO & DAS 2004].

Comment | Synonymy mostly that of OUBOTER (1986). Type Species: Mocoa bilineata GRAY 1846 is the type species of the genus Kaestlea EREMCHENKO & DAS 2004. Phylogenetics: for a phylogenetic analysis of the position of Kaestlea see Ghosh et al. 2023. |
Etymology | Apparently named after the two dorsal stripes in this species. The name of the new genus honours Professor Werner Kästle (1926-2019), German herpetologist, co-editor of the volume ‘Amphibians and reptiles of Nepal.’ (2002), among many other publications. For a brief biography see Kabisch 2019. |
