Abstract

A new species of gobiid fish, Vanderhorstia nobilis, is described from the Philippines and Indonesia on the basis of three specimens, 32.0-43.4 mm SL. Diagnostic features include 16 dorsal soft rays, 17 anal soft rays, 63-68 longitudinal scales, and a moderately stout (females, depth 5.2-5.3 in SL) to  slender (male holotype, depth 6.9 in SL) body. It is similar to a pair of undescribed species from Indonesia and Japan, but clearly differs on the basis of colour pattern, which in males is characterized by a mid-dorsal, neon blue stripe on the head, irregular orange spots, bars, and bands on the cheek, operculum, and adjacent pectoral-fin base, a pair of broad brownish-orange stripes on the dorsal half of body edged with a pair of narrower stripes of pale blue, a dark brown to subtle light brown orange spot (sometimes greatly reduced) on the first dorsal fin between the second and fifth spines, a dark submarginal stripe on the posterior two-thirds of anal fin, and small orange spots covering the pelvic fins. Females are slightly less colourful, but possess a distinctive triangular first dorsal fin with a brownish to bright orange yellow spot narrowing distally to middle of fin.
