Abstract

A new species of gobiid, Hazeus ingressus sp. nov. (Teleostei: Gobiidae) is described from the Levantine coast of Turkey. The spe-
cies probably originates from the Red Sea and represents the 11th alien gobiid species in the Mediterranean Sea. The new species
is distinguished from its Indo-Pacific congeners by a combination of the following characters: no dark blotch on the first dorsal
fin; caudal fin coloration; scales in lateral series 25-28 (modally 27); second dorsal fin rays I,8; anal fin rays I,8-9; predorsal scales
ctenoid 7; short, stout gill rakers 2+8. This finding suggests that the Lessepsian invasion continues with the inclusion of known
species as well as undescribed species.
Keywords: Gobiidae; Hazeus; gobiid fish; alien species; Lessepsian; Levantine Sea.
