A new species of dwarfgoby, Eviota angustifascia n. sp., is described from the Lau Group, Fiji and the island of New Guinea. The new species lacks all cephalic sensory-canal pores. It has a dorsal/anal fin-ray formula of 9/8, 13–14 pectoral-fin rays (all unbranched), the fifth pelvic-fin ray 10–17% of the fourth ray, and the male urogenital papilla not fimbriate. The body is crossed by 5 narrow, white, vertical lines separating wider dark bars, with the bar under the posterior second dorsal fin wider than the orbit diameter.
