A New Species

The genus Haliophis presently consists of two species, H. guttatus (Forsskål, 1755), and a new species from Bali, Indonesia. Descriptions, diagnoses, and a key are provided for these taxa. A step cline occurs in H. guttatus, which ranges from 15° S to 30° N in the western Indian Ocean and Red Sea. Populations from 27 to 30°N differ most from those in the southern Red Sea and Gulf of Aden, but less so from those south of the equator. The step occurs between 20 and 27° N, an area from which no specimens were located, and is congruent with the distributions of at least four other taxa of fishes as well as with several populational differences in other species. This indicates that these distributional patterns may form part of a generalized track, rather than being the result of ecophenotypic effects. In the Red Sea – northern Indian Ocean region, the most common distribution of endemic fishes includes both the Red Sea and the Gulf of Aden. This pattern was not apparent in populations of H. guttatus.

A New Species

A new species of blenniid fish, tribe Salariini, is described based on a 23.8 mm SL specimen collected from the AndamanIslands, eastern Indian Ocean. It differs from other species of Alloblennius in having a pinnately branched supraorbitalcirrus about equal to eye diameter in height; lower jaws with relatively large, darkly pigmented labial flap anteriorly oneach side of chin; pectoral fin with 10 or 11 distinct, small dark spots; and anteriormost preopercular pore position with avertical pair of pores. The distribution of the new species is notable because the four previously described species of thegenus are known only from the western Indian Ocean and Red Sea. A table comparing the five species of Alloblennius is presented.

A New Species

Callogobius winterbottomi new species is described from the 33.8 mm SL holotype and two paratypes (32.2 mm SL and 22.9 mm SL) from the Comoros, Western Indian Ocean. It is distinguished from all other known Callogobius species by the following combination of characters: sensory pores absent, 23–26 scales in lateral series, and sensory papillae pre-opercular row not continuous with transverse opercular row. One additional specimen of Callogobius winterbottomi was located from South Africa. A new standardized naming system for Callogobius sensory papillae rows is presented for identification and clarification of character states among Callogobius species. The new species is tentatively placed among what we term the “sclateri group”, a clade including C. sclateri (Steindachner) and three other species that exhibit a modified female urogenital papilla with lateral distal flaps and elongate ctenii on the caudal peduncle scales. Callogobius tutuilae (Jordan & Seale) is removed from synonymy with C. sclateri because it has partially united pelvic fins (vs separate) and the preopercular sensory papillae row is continuous with the transverse opercular row (vs separate).

Amphimedon (Porifera, Demospongiae, Haplosclerida, Niphatidae), a pantropical genus of reef and mangrove sponges, was recently recorded for the first time from the Red Sea suggesting a rarity which is not sustained by new reef surveys in the Gulf of Aqaba. Here we describe four species of Amphimedon occurring commonly in the Gulf of Aqaba. Among these, three are new to science, A. dinae sp.nov., A. jalae sp.nov. and A. hamadai sp.nov., the fourth one has been recently described as A. chloros Ilan et al., 2004. Although the latter species and our three new species are the first definite Ampimedon species recorded from the Red Sea, at least one previously described sponge from the region, Ceraochalina ochracea Keller, 1889 is suspected to belong to this genus as well. The status of the described and suspected Red Sea Amphimedon is discussed and compared to species recorded from neighbouring Indian Ocean waters.

A New Species

A new species of threadfin bream, Nemipterus flavomandibularis, from the Western Indian Ocean is described and figured. The new species appears most closely related to N. bipunctatus (Valenciennes), but differs principally in colour pattern: N. flavomandibularis is distinct from N. bipunctatus in having two yellow bands on the snout, the upper lip narrowly edged with yellow; and lower lip and chin beneath lip yellow, this colour extending as a narrow band posteriorly to lower margin of opercle. Also, in N. flavomandibularus the scale rows below the lateral line are more or less horizontal (versus distinctly ascending anteriorly in N. bipunctatus), and the maxillary reaches to between level of posterior nostril and anterior margin of eye (versus reaching to below the anterior half of the eye in N. bipunctatus).
