New species of the genus Tryssogobius (Gobiidae) from the tropical the Western Pacific with a complete set of pores of the seismosensory system on the head

Abstract

A new species, Tryssogobius fisunovi sp. n., is described from the depth of 73 m in the region of the Anambas Islands (Indonesia), South China Sea. Based on the presence of the preopercular and orbito-scapular canals, the species is similar to T. porosus, but it differs from the latter species in coloration, location of the mental row of genipores f, separated pelvic fins, and other characters. The problems of the systematics of the genera Tryssogobius and Obliquogobius are discussed.
