Microhyla butleri Boulenger, 1900

Fig. 5F Butler’s Narrow-mouthed Frog

Examined specimens.

Eight male specimens were collected from SAP (UMTZC1064, UMTZC1217, UMTZC1218, UMTZC1219, UMTZC1220, UMTZC1221, UMTZC1222, and UMTZC1223, SVL = 21-25 mm).

Identification.

Morphological characters of the specimens agreed well with the description by Berry (1975) and Garg et al. (2019). Size (SVL: 21-25 mm, n = 8 males); rounded snout; tympanum hidden; upper eyelids without dermal tuberculation; tips of digits dilated into small discs bearing circum-marginal grooves; toes webbed at base; subarticular tubercles small; metatarsal tubercles present; head with whitish streak from the eyes to shoulder; dorsum with wavy markings extending from the eyes to posterior region, forming cross bars on hind limbs with pale edges.

Remarks.

Microhyla butleri was usually found beneath piles of leaf litter and occurs throughout SLF. Despite the fact that all collected specimens were from SAP, many individuals of this species were observed on leaf litter, mostly along roadsides and trekking trails within SRF.
