Abstract
The new species Trimma

combination of characters: 10 predorsal scales; second
spine of first dorsal fin elongated, filamentous,
usually extending beyond base of last segmented ray
of second dorsal fin when adpressed; 13-15 pectoral-fin
rays; fifth pelvic-fin ray unbranched; cheek fully
scaled; transverse lines of cephalic sensory papillae
below eye; interorbital shallowly concave with median
fleshy ridge, and bony width 90.4-99.0% of pupil
diameter; ground color of head and body pale pink,
a broad deep pink longitudinal stripe on side of body,
and a large dark reddish brown blotch on end of midlateral
caudal peduncle when fresh or alive.
