Phrynoidis asper (Gravenhorst, 1829) Asian Giant Toad Fig. 3A

Description.

Three adult males 103.0, 104.3, 104.5 mm SVL, and juvenile 34.5 mm SVL.

Natural history notes.

This riverine species occurs along stream borders but is principally a terrestrial species.

General Distribution.

Tanintharyi, peninsular Thailand and Malaysia to Sumatra, Java, and Borneo.

Molecular Data.

Our specimens are genetically nearly identical to one another (99-100% identical) and some are identical to one specimen in GenBank (DQ158432; FMNH 248148) from Brunei, suggesting low genetic diversity in a potentially high rate of dispersal species. These specimens form a clade with other P. asper from GenBank (Suppl. material 1: Fig. 2).

Specimens examined.

USNM 586969-972.

Red List status.

LC.

Additional bufonids.

We also sequenced two specimens of Duttaphrynus melanostictus from Sagaing, Myanmar (USNM 523959 and USNM 520316), for genetic comparisons. The D. melanostictus species complex is in need of taxonomic revision (e.g. Wogan et al. 2016). Our samples were nested among other D. melanostictus specimens in GenBank (not shown), identical to one (KF665340) specimen (CAS 247174), also from Sagaing but a different locality. We refer to these specimens as D. melanostictus until the species complex is revised.
