Abstract: The gobiid fish Vanderhorstia opercularis is described as a new species from two male specimens, 38.9 and 50.5 mm standard length, collected in 27-40 m off Eilat, Gulf of Aqaba, Red Sea. It lives symbiotically with burrowing alpheid shrimps. It may be distinguished from the 13 valid species of the genus by having 12 dorsal and anal soft rays, 18 to 20 pectoral rays, 40 scales in longitudinal series on the body, a long pointed caudal fin, paired fins that ex­tend beyond the origin of the anal fin, male with a filamentous third dorsal spine, and a color pattern of four dusky bars on the body, each containing a large dark brown spot, an oblique brown bar from the nape across the operculum, with a black spot on the opercle, and numerous small orange-yellow spots over the head, body, and fins, except the pectorals.
