New genus of Ptereleotrinae (Gobioidei) from the South China Sea

A new genus and species Zagadkogobius ourlazon gen. et sp. nov. characterized by an unusual (for the subfamily Ptereleotrinae) combination of characters is described. A single specimen was collected at a depth of 73 m in the southwestern South China Sea to the south of the Anambas Islands. Based on the combination of characters, the new genus is most similar to the genus Nemateleotris. However, the species of the latter genus are associated exclusively with coral reefs. A key to the genera of the subfamily Ptereleotrinae is presented.
