Abstract
Carinotetraodon salivator, a new species of freshwater pufferfish, is described from Sarawak. It differs from its only known congener, C. lorteti, in having a shallower body (depth 36-41% SL, vs. 45- 5 3), 10 anal fin rays (vs. 11), 16-17 pectoral fin rays (vs. 14-15), 17-18 (mode 18) vertebrae (vs. 15-17, mode 16), eyes situated nearer the dorsal profile of the head, a distinct pale blotch present under the lower lip, a white distal margin absent from the caudal fin, and a ventrum which is striped in females and cross-banded in mature males. A lectotype is designated for Tetraodon borneensis Regan, 1902 .
