Abstract
The new species of gobiid fish, Tomiyamichthys emilyae, is described from the Lembeh Strait in North Sulawesi Province of Indonesia, on the basis of 4 specimens, 32.4-43.7 mm SL. Diagnostic features include a large sail-like first dorsal fin without filamentous rays; the bases of the dorsal fins confluent; 10 segmented dorsal and anal-fin rays; 15-17 (usually 17) pectoral-fin rays; scales entirely cycloid, 66-72 lateral and 19-21 transverse scales, no prepectoral or prepelvic scales; the anterior nostril sheathed in an elongate, partially enclosed tube; and a cephalic sensory-canal pore system composed of pores B prime, C, D, E, F, G, M prime, and O prime. The new species is overall brown with 10 or 11 poorly contrasted, darker-brown bars on the lateral body; a dense patch of small white spots on the dorsal surface of the head; the first dorsal fin orange or blue-grey with a mosaic of irregular, dark brown markings; the second dorsal fin yellowish to brown with blue bands or rows of dark brown spots; and the anal, caudal, and pelvic fins dark brown with blue streaks. Type specimens were collected from a gradually sloping, sand/rubble-bottom exposed to periodic strong currents in 17-23 m depth.
