SMF 35090 (5: 6.6–9.3 cm ); SMF 35091 (8: 7.8–10.7 cm ); KAUMM 136 (5: 5.6–8.6 cm ); KAUMM 137 (3: 7.7–9.6 cm ); KAUMM 138 (8: 7.8–9.8 cm ). FIGURE 14. Laeops sinusarabici , SMF 35091, 10.4 cm SL, Jizan, Saudi Arabia. Remarks. Goren & Dor (1994) listed Laeops kitaharae (Smith & Pope, 1906) in their checklist based on examined material by Dor (1970) from Eritrea . Chabanaud’s (1968) description of his new species Laeops sinusarabici was omitted by Goren & Dor (1994) , but later Desoutter et al. (2001) placed this species in synonymy of Grammatobothus krempfi Chabanaud, 1929 , however they did not give a reason for the synonymy. The holotype of G. krempfi (MNHN 1947-0019) has 82 rays in dorsal fin, 66 rays in anal fin, and a body depth of about 2 in SL, which is out of range known for the genus Laeops , which is characterized in having a slender body (body depth 2.2-3.2 in SL) and high count of rays in dorsal and anal fins (83–116 and 67-96, respectively) (Hensley & Amaoka 2001; D. Hensley, unpublished data). Laeops sinusarabici clearly differs from deep-bodied Grammatobothus in combination of these 3 characters: 87–97 rays in dorsal fin, 70–75 rays in anal fin, and body depth 2.2–2.6 in SL. Golani & Bogorodsky (2010) listed the species in their checklist based on Dannie Hensley’s personal communication. Patrice Pruvost of the Muséum National d'Histoire Naturelle (MNHN) provided X-rays of the specimen that is listed as the holotype of Laeops sinusarabici in the catalog (MNHN 1966-369). Characters as observed on these X-rays, which were examined by the first author and from the original description given by Chabanaud (1968) , were found to match with the material caught off Jizan. Our comparison with other species of the genus leads us to conclude that Laeops sinusarabici is a valid species, endemic to the Red Sea. Herein we provide a description of trawled specimens. Description. Dorsal-fin rays 89–95; anal-fin rays 70–74; pectoral-fin rays on ocular side 12–14; lateral-line scales 84–89 (two scales on the base of caudal fin excluded from count); scales cycloid; head scaled, including cheek; interorbital space naked; gill rakers very short, 0 + 7–8; body depth 2.3–2.5 in SL; head length 4.4–5.6 in SL; dorsal profile of head above and posterior to eyes slightly convex; upper eye reaching dorsal profile of head, lower eye in advance of upper; interorbital space very narrow, 14.3–18.7 in head length; snout short (measured from tip of snout to anterior margin of upper eye), 4.5–5.7 in head length; upper-eye horizontal diameter 3.1–3.3 in head length; maxilla reaching to below anterior edge of lower eye, upper-jaw length 4.0– 4.5 in head length; teeth very small, needle-like, on blind side of both jaws only, in 3 irregular rows; origin of dorsal fin slightly behind posterior nostril of blind side; anterior rays of dorsal fin subequal, not prolonged, second ray 3.2–4.4 in head length; distance between second and third rays two times greater than between third and fourth rays; pectoral fin on ocular side shorter than head length, 1.5–2.0 in head length. Color (when fresh): ocular side tan, without markings, dorsal and anal fins darker distally; caudal fin dark.
