A new species of dwarfgoby, Eviota samota, is described from Teluk Saleh, Sumbawa, Indonesia. The new species is characterized by a cephalic sensory-canal pore pattern with only the SOT and paired PITO pores present. This pattern is shared with only two other species in the genus, E. pseudaprica and E. amphipora, which are distinguished from the new species by color patterns and having a dorsal/anal-fin formula of 9/8 (vs. 8/8). The new species has one or more of the ventralmost pectoral-fin rays branched and the fifth pelvic-fin ray is absent. The basic body color of E. samota is red-orange with a golden-yellow head, pectoral-fin base, and caudal-fin base. The new taxon represents the 134th valid species in the genus Eviota. Ocean Science
