Ansonia thinthinae Wilkinson, Sellas & Vindum, 2012 

Description.

Sample of two immature males 22.0, 22.3 mm SVL, mature males 19.5-23.4 mm (n = 5), immature females 21.1-22.8 (n = 6) and two mature females 23.3-25.6 mm SVL.

Natural history notes.

All individuals were on rocks in and alongside small cascades in full canopied areas of forest streams.

General distribution.

Known only from Tanintharyi, Myanmar.

Molecular data.

Our specimens form a single clade with 99-100% similarities based on 16S data, and are 96-97% similar to the type series from northern Tanintharyi, Myanmar ( Wilkinson et al. 2012). We note that the type series forms a clade with our samples, and that clade is sister to A. kraensis  (AB435250-52) to the exclusion of other peninsular species ( Grismer et al. 2017). The long branch between our samples and the type series may represent genetic variation associated with geography in a low-dispersal group, or it suggests this may represent a species complex (see Suppl. material 1: Fig. 2).

Comments.

The sample appears to represent a single reproductive-season cohort amid maturation. If our assessment of maturity is correct, this population has slightly smaller adults than the more northern topotypic population where adult males were 22-28 mm SVL and a single adult female was 31.8 mm.
