A new species of gobiid fish, Trimma putrai, is described from 4 localities in Indonesia and Timor-Leste (Bali, Flores, Raja Ampat Islands, as well as Atauro Island in Timor-Leste). It shares a combination of features with three other species: scales present on the predorsal midline and upper opercle; no scales on the cheek; the second spine of the first dorsal fin elongate and reaching beyond the origin of the second dorsal fin when adpressed; at least some branched pectoral-fin rays; a branched fifth pelvic-fin ray; and the absence of deep narrow trenches
between and behind the eyes. It differs from the three species primarily in color pattern, having yellow, orange, or red bars on the cheek and yellow-to-red spots on the anterior body that lack discrete dark centers.
