has only been recorded in the extreme south-west of that state, adjacent to Brunei. Sumatran material is recorded on the basis of digital images taken by Mr Fahmi (Lembaga Ilmu Pengetahuan Indonesia, LIPI) from fish markets in Riau province, north-east Sumatra. The catch location of specimens from the fish markets in Jakarta could not be determined. However, vessels suppling these markets often fish along the coasts of Sumatra and Borneo. Habitat possibly restricted as it appears to be most abundant near the coast in regions of high riverine outflow, particularly at and near Mukah, Sarawak.

from the nearby Persian Gulf (off Kuwait, BPBM 33148, 27 cm DW), all have a short, relatively obtuse snout lacking a dense coverage of denticles. The Red Sea specimens, whose shape may have changed slightly due to being stuffed, are similar morphometrically to the Persian Gulf specimen, and collectively differ in shape from

The Red Sea specimens also have a much shorter-based (fold length 82-89% versus 105-130% DW) and deeper (fold depth below its midbase 3-3.4 times versus 1.8-2.4 times tail depth at same point, fold length 17-20 times versus 32-41 times its depth below midbase) ventral cutaneous fold.
