Fig. 5G Heymon’s Narrow-mouthed Frog

Examined specimens.

Nine specimens were collected from SRF (Males: UMTZC1028, UMTZC1067, UMTZC1224, and UMTZC1226, SVL = 17-24 mm; Females: UMTZC1008 and UMTZC1066, SVL = 25-27 mm) and SAP (Males: UMTZC1320 and UMTZC1489, SVL = 17-20 mm; Female: UMTZC1343, SVL = 29 mm).

Identification.

Morphological characters of the specimens agreed well with the description by Berry (1975), Garg et al. (2019) and Sumarli et al. (2015). Size (SVL: 17-24 mm, n = 6 males; 25-29 mm, n = 3 females); rounded snouts, projecting beyond lower jaw; tympanum barely visible; supratympanic fold distinct; tips of digits dilated to form large disc bearing circum-marginal grooves; toes basally webbed; dorsum with pale coloured vertebral stripe, with black marks on each side, and dark stripe on lateral sides from tip of snout until groin; ventral surface of foot is dark brown.

Remarks.

Microhyla cf. heymonsi was commonly found beneath piles of leaf litter and in rock crevices throughout SLF. This species was also found to occur in similar man-made ponds as with other species of Microhyla . Active and loud calling could be heard from this species after rains. The species is considered a commensal species that is tolerant of habitat alteration ( Badli-Sham et al. 2019).
