Gerald R. Allen, Mark V. Erdmann & William M. Brooks
A new species of gobiid fish, Vanderhorstia vandersteene, is described from the East Cape region of Milne Bay Province, Papua New Guinea on the basis of five specimens 17.5-32.2 mm SL. Diagnostic features include dorsal-fin elements VI-I,10-12; the fourth dorsal-fin spine filamentous, reaching the base of about the fifth to seventh segmented dorsal-fin ray when adpressed; anal-fin rays I,11; pectoral-fin rays 16-18; lateral scales 35-37; transverse scales 10; body scales mostly ctenoid, except cycloid scales anterior to the level of about the second-dorsal-fin origin, as well as on the pectoral-fin base, prepelvic region, and the lower side between the pectoral-fins and pelvic fins; scales absent on the head, including medially and anteriorly on the predorsal region; the caudal fin lanceolate with an elongate, median filament; color in life light neon blue with a wavy yellow-orange stripe from the upper operculum to the upper caudal-fin base, prominent yellow-orange bars, bands, and spots on the head and upper sides, a pair of yellow stripes on the second dorsal fin, and yellow streaks and bands on the caudal fin. We include a key to the Vanderhorstia species with low lateral-scale counts (less than 45).
