Abstract
Two new species of the sciaenid genus Johnius (Johnius) are described: J. trewavasae from Taiwan, Hong Kong, and Singapore, differs from all other congeners in having 24-27 dorsal soft rays, 5 - 6 scales above and 7-10 scales below the lateral line, 6-8 obtuse lower gill rakers, the last pleural rib on the 11th vertebra, and a shorter lower jaw (33.8-38.4% HL); J. latifrons from Thailand and Java is characterized by 25-29 dorsal soft rays, 7-9 scales above and 11-14 scales below the lateral line, 7-9 obtuse lower gill rakers, a wide interorbital width (26.1-30.6% HL), a small eye (16.7-26.4% HL), and a short, second anal spine (25.9-37.1% HL). Two related species, J. heterolepis Bleeker from “Suriname” and J. cantori Bleeker from Malaya, are resurrected as valid West Pacific species of Johnius (Johnius).
