Two new species of the gobiid genus Coryogalops, C. guttatus sp. nov. and C. pseudomonospilus sp. nov., are described from the Red Sea. Coryogalops guttatus sp. nov. is distinguished from its congeners by having dorsal-fin rays VI + I,12; anal-fin rays I,10-11; pectoral-fin rays 17, three upper rays with free tips; pelvic fins I,5, joined to form a disc, weakly emarginate, with pelvic frenum reduced; longitudinal scale series 33-35; transverse scale rows 9-10; circumpeduncular scales 10-11; seven transverse suborbital rows of sensory papillae on cheek; no tentacle above upper eye margin; anterior nostril tubular, with triangular lappet extending from posterior rim, posterior nostril slightly raised; dark orange spots on many of the scales below body midline form a longitudinal pattern, each spot covering one scale; two distinct dark spots behind edge of preopercle, and similar pair of spots at pectoral-fin base. Coryogalops pseudomonospilus sp. nov. is distinguished from congeners by having dorsal-fin rays VI + I,11; anal-fin rays I,10; pectoral-fin rays 16-17, two upper rays with free tips; pelvic fins I,5, joined to form a disc, moderately emarginate, with pelvic frenum well-developed; longitudinal scale series 33-35; transverse scales rows 9; circumpeduncular scales 12; seven transverse suborbital rows of sensory papillae on cheek; no tentacle above upper eye margin; anterior nostril tubular, without lappet from posterior rim, posterior nostril slightly raised; and irregular dark maroon mark covering lower part of the first three membranes between spines of first dorsal fin. The distribution of species restricted to the western Indian Ocean is discussed, and a key to the species of the genus is provided.
描述了来自红海的虾虎鱼科Coryogalops属的两个新物种,即斑点Coryogalops guttatus sp. nov.和拟单斑Coryogalops pseudomonospilus sp. nov.。斑点Coryogalops guttatus sp. nov.与其同属物种的区别在于:背鳍鳍条为VI + I,12;臀鳍鳍条为I,10 - 11;胸鳍鳍条17,上方三根鳍条末端游离;腹鳍I,5,愈合形成吸盘,微凹,腹鳍系带退化;纵列鳞33 - 35;横行鳞9 - 10;围尾柄鳞10 - 11;颊部有七排横向的感觉乳突;上眼缘上方无触须;前鼻孔管状,后缘有三角形叶瓣延伸,后鼻孔稍隆起;身体中线以下许多鳞片上有深橙色斑点形成纵向图案,每个斑点覆盖一片鳞片;鳃盖骨边缘后方有两个明显的黑斑,胸鳍基部有类似的一对斑点。拟单斑Coryogalops pseudomonospilus sp. nov.与其同属物种的区别在于:背鳍鳍条为VI + I,11;臀鳍鳍条为I,10;胸鳍鳍条16 - 17,上方两根鳍条末端游离;腹鳍I,5,愈合形成吸盘,中度凹陷,腹鳍系带发达;纵列鳞33 - 35;横行鳞9;围尾柄鳞12;颊部有七排横向的感觉乳突;上眼缘上方无触须;前鼻孔管状,后缘无叶瓣,后鼻孔稍隆起;第一背鳍棘间前三根鳍膜的下部有不规则的暗栗色斑。讨论了仅限于西印度洋的物种分布,并提供了该属物种的检索表。
