Occidozyga sp. A-D

Description.

We were unable to identify two of the Tanintharyi specimens to species, an adult female 20.8 mm, adult male 22.1 mm SVL. Dorsal skin lightly rugose; broad mid-dorsal brown stripe bordered by broad parasagittal tan stripes on dorsum; posterior thigh without dark horizontal bar although with sharp delineation between dorsal brown and ventral white; venter immaculate white.

Natural history notes.

Occurred in the same area as the previous two Occidozyga species.

General Distribution.

Occidozyga sp. A–B are known from Yangon, Occidozyga sp. C is known from Bago, and Occidozyga sp. D is known from Tanintharyi.

Molecular Data.

We included other Occidozyga from the legacy collection for comparative purposes. These individuals were very different genetically from the Tanintharyi specimens, and some from each other, including individuals from the same geographic regions forming different clades. This is likely a cryptic species complex; therefore, we treat each of these clades as separate, unidentified species, each was placed in its own COIBIN: O. sp. A from Yangon (USNM 587386, USNM 587389, and MBM JBS 19932; ADG1328), O. sp. B from Yangon (USNM 587395 and USNM 587402; ADG1330), O. sp. C from Bago (USNM 587105 and USNM 587107; ADG2685), and our specimens from the Tanintharyi Region as O. sp. D (USNM 586928-29; ADG1329).

Red List status.

Additional dicroglossids.

We sequenced several other dicroglossids for comparison, including three specimens of Hoplobatrachus tigerinus from Yangon (USNM 587325, USNM 587404) and Bago (MBM- USNM-FS 35607). These were placed in a 16S clade with specimens from GenBank labeled as H. cf. tigerinus MS 2009 (AB530502 and AB543600) and MS 2011 (AB671173-81). These specimens are now considered to be H. litoralis , a recently described species from Cox’s Bazar district of Bangladesh ( Hasan et al. 2012b), which extends the range of this species into Myanmar. Our 16S sequences range from 2.0-3.5% sequence divergence from the Bangladesh sequences, including one of the paratypes (AB671174). Two specimens of Hoplobatrachus rugulosus from Sagaing (USNM 520480, USNM 524038) were sequenced and placed in a 16S clade with other individuals in GenBank identified as H. rugulosus . We sequenced two individuals of Sphaerotheca breviceps from Sagaing (USNM 524020, USNM 537466) that were placed in a 16S clade with individuals in GenBank identified as S. breviceps .
