Scorpaena Porcus

The scorpionfish Scorpaena decemradiata n. sp. is described from off the coast of Israel in the Gulf of Aqaba, northern Red Sea. The new species is similar to S. porcus Linnaeus, 1758, but is characterized by dorsal fin spines XII, soft dorsal fin rays 10 (the last divided at base); pectoral fin rays 16, uppermost branched pectoral fin ray is the second; lacrimal with 2 spines over maxilla that point at nearly right angle from each other, the posterior pointing ventrally and slightly anteriorly; occipital pit well developed; anteriormost mandibular lateral-line pores small, separated; scales ctenoid; 59-62 scale rows in longitudinal series; scales absent on chest and pectoral fin base; and cirri developed over entire head and body, but no cirri on lower jaw. An updated checklist of the species of the genus Scorpaena Linnaeus, 1758 and a key to the species of the eastern Atlantic, Mediterranean Sea and Red Sea are presented.

Two new species of the gobiid genus Hetereleotris, H. aurantiaca sp. nov. and H. semisquamata sp. nov., are described from the Red Sea, the former from Saudi Arabia at Jeddah from the cave at depth of 14–16 m, and the latter from the southern Egypt from reef flat. Hetereleotris aurantiaca sp. nov. is distinguished from its congeners by having dorsal-fin rays VI + I,10; anal-fin rays I,9; pectoral-fin rays 14, all rays branched; pelvic-fin rays I,5, the fin separated and without frenum, 5th ray unbranched; anterior nostril with a long tube without process from the rim, posterior nostril a pore with erected rim; no tentacle above eye; posterior angle of jaws extending posteriorly to below posterior edge of pupil; no opercular spine; no mental frenum; pelvic fins longer than pectoral fins; squamation reduced to a few scales on caudal peduncle at caudal-fin base; no head canals; by presence, size and pattern of suborbital rows of sensory papillae; and orange head and yellowish orange body with five faint brown bars. Hetereleotris semisquamata sp. nov. is distinctive among its congeners by unique scale pattern (scales cycloid, the squamation reduced, tapering from caudal-fin base along lateral midline towards pectoral fin where nearly reaching its base) and by coloration (head and body whitish, with brown line from eye to end of upper lip, dark brown band across interorbital area and continuing obliquely from eye to corner of opercle, broad dark brown band below first dorsal fin continuing into fin, and moderately broad dark brown bar on caudal-fin base). Furthermore, it is characterized in having dorsal-fin rays VI + I,11, anal-fin rays I,10, pectoral-fin rays 16, and absence of head canals. In addition to descriptions of two species, a key to all species of Hetereleotris is provided. Hetereleotris psammophila is reported outside the Gulf of Aqaba for the first time.

Two new species of Trimma are described from Fiji. Trimma bathum n. sp. lacks scales on the cheeks, opercle and predorsal midline, has 18–19 unbranched pectoral fin rays, an unbranched 5th pelvic fin ray that is 40–56% the length of the 4th ray, 17–18 gill rakers on the outer surface of the first gill arch, a U-shaped interorbital and a narrow slit-like postorbital trench, a low, median fleshy ridge extending half-way towards the orbit from the origin of the first dorsal fin, and, when freshly collected, a pink head and body with most body scales having an orange-brown spot or short bar at their centres. The species is currently known only from off Suva Harbour, Viti Levu, Fiji. Trimma finistrinum n. sp. has a bony interorbital equal to the pupil diameter, a fully scaled nape of 12–14 scales, a second dorsal spine that may reach posteriorly to the middle of the second dorsal fin, the papillae in the longitudinal row immediately below the eye either single or with two papillae in a vertical row, unbranched pectoral fin rays, usually a branched fifth pelvic-fin ray that is about half length of the fourth ray, and a large diffuse dark blotch on the posterior part of the caudal peduncle. A colour pattern of a brownish body with most body scales having golden- to greenish-yellow (pale in preservative) centres is unique among species of the genus. The species is currently recorded only from off the north and east coasts of Viti Levu, Fiji.

Schindler’s fishes (Schindleria) are extremely paedomorphic and only a few morphological characters are suitable for species delimitation of these tiny fishes. Three of these key morphological characters, the (i) origin of the dorsal fin relative to the anal fin, (ii) number of vertebrae and (iii) coloration, need reinterpretation in a recently described species, Schindleria nigropunctata. To avoid nomenclatorial problems S. nigropunctata is redescribed from the type material. This species is characterized by 16–17 dorsal fin rays, 16 pectoral fin rays, origin of the anal fin ventral to the 8th dorsal fin ray, 37–38 myomeres, a uniform greyish-white colored body (preserved) and a trunk without obvious pigmentation (no black pigment spots). The eyes are dark grey with a silvery cornea. Dorsally on the cornea are blackish melanophores arranged in a sickle-shaped pattern.

Two new species of Trichomycterus from isolated small river basins of southeastern Brazil are described: T. pantherinus, new species, from the Rio Santa Maria da Vit ria basin, and T. caudofasciatus, new species, from the Rio Itabapoana basin. Both new species are diagnosed by a combination of morphological features, also occurring in T. alternatus and T. longibarbatus, including number of pectoral-fin rays, odontodes and branchiostegal rays, long filamentous first pectoral-fin ray and wide opercular patch of odontodes. Trichomycterus pantherinus differs from other congeners by possessing a light orangish yellow flank with dark brown to black rounded spots. Trichomycterus caudofasciatus is distinguished from other species of the genus by having four gray bars on the caudal fin.

The clingfishes Lepadichthys frenatus Waite 1904 and Lepadichthys misakius (Tanaka 1908) are both redescribed as valid species, although the latter has previously been regarded as a junior synonym of the former. Lepadichthys frenatus and L. misakius are easily distinguished from their congeners by the following combination of characters: 14–19 dorsal-fin rays; 12–14 anal-fin rays; disc size moderate, its length 15.1–20.8 % of standard length (SL); and dorsal, anal and caudal fins connected by membranes. Lepadichthys misakius can be distinguished from L. frenatus by having 25–28 (modally 26 or 27) pectoral-fin rays [vs. 27–29 (29) in L. frenatus]; the upper end of the gill membrane level with the 5th to 8th (usually 6th) pectoral-fin ray base in lateral view [vs. 6th to 8th (7th)]; the lower 8th to 11th (9th) pectoral-fin ray base attached to the disc base by membrane [vs. 10th to 12th (11th)]; 7–11 (9) gill rakers on each arch [vs. 11–14 (12)]; anterior, posterior and least interorbital widths 9.0–11.8 (mean 10.7), 13.4–16.9 (15.3) and 3.2–8.8 (6.2) % SL, respectively [vs. 8.4–10.2 (9.4), 12.1–14.7 (13.5) and 2.8–5.9 (4.8) % SL, respectively]; and NC2 (nasal canal pore) usually located between the anterior and posterior margins of the posterior nostril (vs. usually located before the posterior nostril anterior margin). Morphological changes with growth of the two species are described in detail and a lectotype designated for L. frenatus.

A new species of deepwater gurnard, Pterygotrigla (Otohime) madagascarensis sp. nov. is described, based on two specimens collected on the upper continental slope south of Madagascar, in the southwestern Indian Ocean. The new species belongs to the tropical Indo-Pacific subgenus Otohime in having a short rostral projection, short posttemporal spine, long opercular spine and no cleithral spine. It is most similar to P. (O.) multipunctata, and P. (O.) urashimai, in having no large blotch on the first dorsal fin, a jet-black blotch and no white ocellus on the inner pectoral-fin surface, with no scales on the breast and front of the pectoral-fin base. However, the new species differs from the latter two species by the combination of the following characters: first dorsal-fin spines 7, second dorsal-fin rays 12, dusky rays on the inner pectoral-fin surface, one row of blackish botches on second dorsal fin, and no papillae on the dorsal surface of oral cavity. A key is provided for the twelve Pterygotrigla species now in the subgenus Otohime.
