Collection localities of freshwater and coastal fishes from Kalimantan that included specimens of the genus Phenacostethus. TGK01/ TGK32 and TGK02, localities of Phenacostethus sikat. The holotype was collected at TGK01. TGK18 is the locality of Phenacostethus sp. 1, represented by one specimen (USNM 443825) distantly separated from Phe. sikat in mt COI data (see Table 4 and Discussion). Blue dots represent other localities sampled in August 2007 which included no phallostethid specimens. Yellow lines are roads. Base map from Microsoft Encarta Interactive World Atlas 2001.	Fig. 6.
