Parapercis randalli, a new sandperch (Pisces: Pinguipedidae) from southern Taiwan

Abstract

Parapercis randalli sp. nov. is described on the basis of four specimens collected in southern Taiwan by angling at a depth of 5–150 m. It differs from its congeners in having five broad reddish brown saddles on the dorsal surface; both jaws and anterior portion of snout reddish orange; a yellow bar with red margin on cheek; a series of 8 red bars below body axis; configuration of spots on head, dorsal and caudal fins; and a combination of morphological characters: three pairs of canine teeth anteriorly in lower jaw; no palatine teeth; vomerine teeth stout, in a single curved row; lateral-line scales 53; margin of preopercle smooth; 4th dorsal spine longest; caudal fin slightly rounded on ventral half, truncate on dorsal half, with a prolonged upper lobe; appressed pelvic fin extends beyond anus. A total of 21 valid pinguipedid species are now recorded from Taiwanese waters.
