Natural history notes.
Collected at 1000 hours near Yeybuchaung-ngal stream, approximately 100 meters downstream from Camp 1.
Tanintharyi southward through Malaya Peninsula to Java and Sumatra.
There are no other COI sequences in BOLD for A. mycterizans . Our specimen was placed in its own COIBIN and the 16S is 99% similar to other A. mycterizans in GenBank (KX660161, KX660205; no locality data provided) and was placed in a 16S clade with these specimens and an "A. prasina" (FMNH 269042 from Borneo) that is likely misidentified (KX660195).
This species was an unsuspected find, because it had not been reported previously from Myanmar and the closest Thai records are in southern Thailand south of the Isthmus of Kra. This specimen represents the northernmost record of this species (see Lee et al. 2015). A second specimen ( CAS 247859) was confirmed (JLL) further south from Kawthaung, Tanintharyi Region, Myanmar previously identified as A. prasina .
