<i>Johnius javaensis</i>, a new species of croaker (Acanthuriformes, Sciaenidae) from the southern coast of Java, Indonesia.

ABSTRACT: In this study, we describe a newly recognized croaker (Sciaenidae), Johnius javaensis sp. nov. based on five specimens (87-121 mm in standard length) from the southern coast of Java, Indonesia.

Johnius javaensis sp. nov. is characterized by five vesicular mental barbels on the chin, 30-32 dorsal-fin rays, seven or eight scale rows below the lateral line; 11 or 12 lower gill rakers, 11 or 12 swim-bladder appendages, and ventral margin of the sagitta head expanded into a distinct convexity. Historically, four Johnius spec
