Abstract

A new species of triplefin fish (Blenniiformes: Tripterygiidae), Helcogramma williamsi, is described from six specimens collected from southern Taiwan. This species is well distinguished from its congeners by possessing 13 second dorsal-fin spines; third dorsal-fin rays modally 11; anal-fin rays modally 19; pored scales in lateral line 22-24; dentary pore pattern modally 5+1+5; lobate supraorbital cirrus; broad, serrated or palmate nasal cirrus; first dorsal fin lower in height than second; males with yellow mark extending from anterior tip of upper lip to anterior margin of eye and a whitish blue line extending from corner of mouth onto preopercle. Comparisons and a diagnostic key are provided for the species of Helcogramma now known from Taiwan: H. fuscipectoris, H. inclinata, H. striata, H. trigloides, and the newly recorded, H. rhinoceros.
