A new species of Trimma (Pisces: Gobiidae) from the deep reefs of Palau, western Pacific Ocean

A new species of Trimma is described from three specimens from deep reefs (91.4 m) at Uchelbeluu Reef, Palau, western Pacific Ocean. Trimma panemorfum n. sp. is characterized by a live colouration of a yellow to orange body with two light blue stripes, each with a ventral bar of the same colour from the anterior origin. The predorsal midline is scaled, opercular and cheek scales are absent, the middle 12-13 pectoral-fin rays are branched, the fifth pelvic-fin ray has two dichotomous branch points (total of four branch tips), the bony interorbital is 34-42% pupil width and does not extend ventrolaterally beyond the fifth papilla of row p, where the posterior interorbital trench is present as a slight groove or absent.
