New record of Glossogobius laticeps (Gobiiformes: Gobiidae) from Taiwan with notes on local congeneric species

Abstract

In this study, the Taiwanese Glossogobius giuris population is proven to be a new western Pacific distributional record for Glossogobius laticeps. The new addition to Taiwanese Glossogobius fauna can be characterized by having longitudinal scale rows 33-35, transverse scale rows 9-11 and predorsal scale rows 22-24. Infraorbital papillae row a branched, and rows b, cp1 and cp2 in a patch of multiple minute papilla. Trunk distinctly pigmented with numerous longitudinal black streaks in juvenile and adult, tip of chin with two small patches of melanophores and mostly unpigmented medially. A more detailed description of the genotyped materials is provided, with a discussion of the species' distribution expansion.
