A new species of Luciogobius Gill (Teleostei: Gobiidae) from northern Taiwan

Abstract

A new gobiid fish of Luciogobius Gill, 1859 had recently been collected from the intertidal waters of northern Taiwan. The new species, Luciogobius delicatus sp. nov., is characterized by the following unique combination of features: (1) second dorsal fin rays: I/10 and anal fin rays I/12; (2) pectoral fin rays 14 and with one upper, short free soft ray; (3) vertebral count: 22 + 22 = 44; and (4) specific coloration: body and head rather light, creamy yellow. Pectoral fin base with several tiny black spots. Caudal fin pale brown. Second dorsal fin translucent with tiny black dots. A brief discussion of their own related species would also be addressed.
