Abstract

A new species of dwarfgoby, Eviota atauroensis n. sp. is described from Berau Bay, Atauro Island, Timor-Leste. The new species is distinguished by having the cephalic sensory-canal pore system lacking only the IT pore (pattern 2); a dorsal/anal fin-ray formula of 9/8; 4 or 5 lower pectoral-fin rays branched; the fifth pelvic-fin ray rudimentary; two distinct dark spots on the pectoral-fin base and no additional spot ventral and anterior to the pair; 5 dark postanal ventral spots; a postocular spot; a dark spot on the caudal peduncle centered above the midline; and the male urogenital papilla cup-shaped (the shapes of urogenital papillae in Eviota are clarified here). The new species is currently known only from Atauro Island in Timor-Leste, where it was collected from the upper surfaces of Porites coral bommies situated in a shallow subtidal (0.5-2 m) surge zone.
