Etymology: Thryssocypris: Greek, thrissa, -es = shad + Greek, Kypris, other name for Aphrodite, proceeding from Cyprus (Kypris), Greek, kyprinos = carp (Ref. 45335); tonlesapensis: From Tonle Sap, the enormous permanent backwater of the lower Mekong, into which the Prek Tamen and Prek Tasom flow (Ref. 31464).

背的軟條 (總數) : 9 - 10; 臀鰭軟條: 15 - 16; 脊椎骨: 43 - 44. Immediately distinguished from T. smaragdinus by its much smaller head, more numerous scales (44-46 in lateral line series versus 36-39), and more numerous anal fin rays (151/2 - 161/2 versus 121/2 - 141/2). The very striking difference in size of the pharyngeal jaws of tonlesapensis, the linear dimensions of which are only about half as great as in T. smaragdinus, is much greater than would be expected if this difference were due only to the difference in head size, since the head is only about 20% longer in T. smaragdinus. Gill rakers on first gill arch 8.
用它的較小頭部，眾多的鱗片 (44-46 在側線系列中對 36-39) 與眾多的臀鰭棘條緊鄰與 T. smaragdinus 區分了 (151/2- 161/2 對 121/2- 141/2). 在大小方面的非常顯著的不同 tonlesapensis 的咽顎, 線狀尺寸那是只有大約一半如大的當在 T. smaragdinus 中, 是大於將會被預期出現如果這不同是適當的唯一到不同頭長比率大小, 自從頭部之後是只有大約 20% 比較長的在 T. smaragdinus 中. 在第一個鰓弓 8 上的鰓耙.
Found near the water surface. Highest numbers mainly in the tidal zone of large deltaic branches of the lower Mekong. Feeds on insect larvae. Sometimes seen in the markets, but usually used for making prahoc and tuk trey (Ref. 12693).
發現於靠近水面了。 最高的數字主要在下面湄公河的大三角洲支流的潮間帶。 吃昆蟲幼生。 有時在市場中見到, 但是通常用來了製造 prahoc 與 tuk trey.(參考文獻 12693)
