A new species of goby, Eviota rubriceps, most similar to E. nigrispina, is described from Indonesia, Papua New Guinea, and the Philippine Islands. Both species have the lower two thirds of the body dark in preserved specimens, belong to the cephalic sensory-pore pattern group 2 of Lachner and Karnella (1980), have an 8/7 dorsal/anal formula, and unbranched pectoral-fin rays. Eviota rubriceps differs from E. nigrispina in live and preserved coloration and in caudal-peduncle depth. The descriptions of E. mikiae and E. raja are expanded based on additional materials.

Nandus prolixus sp. nov. is described from the Sepilok River drainage in Sabah, northeastern Borneo. This species is distinguished from its only Sundaic southeastern Asian congener, N. nebulosus, in having a longer, more produced snout (25.7–30.6% HL vs. 18.5–26.1), more lateralline scales (33–37 vs. 24–34), more scales below the lateral line (12 vs. 10–11), fewer spines in the dorsal fin (XIV vs. XV–XVI), and fewer pectoral-fin rays (15–16 vs. 17–19). It differs from N. nandus (from India) in having fewer lateral-line scales (33–37 vs. 42–55), fewer scales above the lateral line (4–5 vs. 6–7), fewer scales below the lateral line (12 vs. 14–18), more dorsal spines (XIV vs. XII–XIII), and the absence (vs. presence) of a distinct dark spot at the base of the caudal peduncle. It differs from N. oxyrhynchus (from mainland southeastern Asia) in having a more slender body (body depth 37.6–40.5% SL vs. 41.3–44.1) and a less steeply sloping predorsal profile.

A new species of small-sized scorpionfish, Scorpaena bulacephala, is described on the basis of seven specimens collected from off Norfolk and Lord Howe Islands, northern Tasman Sea, southwestern Pacific Ocean, at depths of 86–113 m. The new species is closely related to a Hawaiian endemic species, S. colorata. The two species are distinguished from other Indo–Pacific species of Scorpaena by the following combination of characters: exposed cycloid scales covering the anteroventral surface of the body and pectoral-fin base, the lateral surface of the lacrimal without spines, and 17 pectoral-fin rays. The new species differs from S. colorata in having 39–44 longitudinal scales rows and relatively short fin spines and rays, especially short longest pectoral-fin ray (31.5–33.5% of standard length). Morphological changes with growth and sexual dimorphism of the new species are also discussed.

ABSTRACT A new species of Moenkhausia is described from the upper rio Machado at Chapada dos Parecis, rio Madeira basin, Rondônia State, Brazil. Among congeners, the new species is similar to Moenkhausia chlorophthalma, M. cotinho , M. lineomaculata , M. plumbea, and M. petymbuaba by having dark blotches on the anterior portion of the body scales, which are absent in the remaining species of the genus. The new speciesdiffers from aforementioned species by possessing blue eyes in life, 15-18 branched anal-fin rays, and a well-defined, round caudal-peduncle spot that does not reach the upper and lower margins of the caudal peduncle and does not extend to the tip of the middle caudal-fin rays.

Four species treated as valid have VII first-dorsal spines: Apogon fasciatus with two brownish stripes on each side of the head and body to caudal peduncle and a faint, variable stripe along a portion of the lateral-line, 16 (15) pectoral-fin rays, and 14–17 (12, 13 or 18) gill rakers, Apogon quinquestriatus with four brownish stripes on each side of head and body, two reaching the caudal peduncle, 15 pectoral-fin rays, and 15 gill rakers, Apogon septemstriatus with three brownish stripes on each side of head and body, three reaching the caudal peduncle, 14 (13) pectoral-fin rays, and 14–16 gill rakers, Apogon pleuron, new species, with two brownish stripes on each side of head and body reaching the caudal peduncle, ventral edge of midlateral stripe with vertical bars, 15 (14 or16) pectoral-fin rays, and 17–20 (15, 16 or 21) gill rakers. Two species treated as valid have VI first-dorsal spines: Apogon bryx with three brownish stripes on each side of head and body, two reaching the caudal peduncle, 14–15 pectoral-fin rays, and 22–23 (21 or 24) gill rakers, Apogon kiensis, with two brownish stripes on each side of head and body reaching the caudal peduncle, 14–15 pectoral-fin rays, and 16–18 (15 or 19-20) gill rakers.

A New Species

A new species of Gephyrocharax is described from the río Cascajales basin, a tributary of the río La Colorada, río Magdalena system, Colombia. The new species is distinguished from its congeners, exceptG. melanocheir, by the absence of an adipose fin in most specimens and by the possession of a lateral branched pectoral-fin ray in males with a distal fan-shaped structure with minute bony hooks and a dark blotch or a few scattered dark brown chromatophores along its branches. The new species differs from G.melanocheir by the absence of an intense black pigmentation at the base of the anterior five dorsal-fin rays, the number of vertebrae (40-41vs. 38-39), the frontals contacting each other anterior to the epiphyseal bar in adults (vs. the absence of contact), the posterior margin of the mesethmoid straight in its central portion (vs. strongly concave at this point), the pouch scale of mature males reaching caudal-fin ray 11 or the area between caudal-fin rays 11 and 12 (vs. reaching only to caudal-fin ray 10 or the area between caudal-fin rays 9 and 10), the number of minute terminal branches of the lateral branched pectoral-fin ray of mature males (60-88 vs. 28-54), a longer black lateral stripe along the body in males (reaching to the base of the caudal-fin rays vs. reaching the middle of the length of the caudal peduncle), and the snout length (28.3-31.8% HLvs. 22.2-28.0% HL). The diagnosis ofGephyrocharax is modified to include species with the adipose fin variably present

Two new species of goby, Eviota ancora and Eviota rubriguttata, are described from the Ryukyu Islands, Japan. Eviota ancora belongs to the cephalic sensory-pore system pattern group 2, has a dorsal/anal fin-ray formula of 8/7, simple pectoral-fin rays, and a distinctive hook-shaped orange mark on the side of the head in life. Eviota rubriguttata belongs to the cephalic sensory-pore system pattern group 1, has a dorsal/anal fin-ray formula of 8/7, branched pectoral-fin rays, the body peppered with tiny black chromatophores, and round red spots on the dorsal and anal fins in life.

The Pseudochromis reticulatus complex is diagnosed to include species of Pseudochromis with the combination of a pointed caudal fin (rounded with middle rays produced), a reticulated colour pattern on the upper part of the body, dorsal-fin rays modally III,26, anal-fin rays modally III,15, and pectoral-fin rays modally 18. Members of the complex include P. reticulatus Gill & Woodland, P. pictus Gill & Randall, P. tonozukai Gill & Allen, P. jace Allen, Gill & Erdmann and P. stellatus new species. The last-named is herein described from six specimens from Batanta and Batu Hitam in the Raja Ampat Islands, West Papua, Indonesia. It is distinguished from other members of the complex in live coloration, and in having higher mean numbers of scales in lateral series and of anterior lateral-line scales (36–38 and 29–32, respectively), and a deeper body as measured from the dorsal-fin origin to pelvic-fin origin (31.8–33.5 % SL).

Botia udomritthiruji sp. nov. is described from the Tenasserim River drainage in southern Myanmar. It can be distinguished from congeners by its color pattern, consisting of five dark vertical bars on the body, with the central portion of these bars paler than its edges; with increasing age, the edges of these bars become more irregular and darker, and irregular dark spots on the pale interspaces begin to form, sometimes fusing with the edges of the vertical bars. In morphology, it differs from congeners by a combination of: body depth at anus 23.4–27.7% SL, caudal peduncle depth 15.9– 18.7% SL, and 12 dorsal-fin rays. Evidence for considering B. macrolineata a junior synonym of B. dario and for considering B. rostrata a species distinct from B. almorhae is also presented here.
