Rhinoptera javanica Müller & Henle

( Figs. 3B View FIGURE 3 , 11 View FIGURE 11 E–H)

The single specimen (SL-20) of cownose ray examined was landed at the Erinchamman Kovilady market in Point Pedro in the Northern Province. Seven of 10 species in this genus were included in our molecular analysis, with this specimen clustering most closely with our reference specimen of Rhinoptera javanica (VN-94; JQ518924 View Materials ) from Vietnam, but differing from the latter specimen by 5 bp. The specimen from Sri Lanka was morphologically consistent with R. javanica in its possession of a long tail and seven rows of teeth in both the upper and lower jaws, the middle three rows of which are much broader than the lateral rows.

This name is in current use for this species in Sri Lanka (see De Bruin et al. 1995; Morón et al. 1998; De Silva 2006).
