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.
Known only from Tanintharyi, Myanmar.
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).
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.
