A new species of anthiine fish (Serranidae) belonging to the genus Giganthias from southeastern Indonesia is described.This is the second species recorded for this genus and the first record of this genus in Indonesian waters. The new species,Giganthias serratospinosus, is clearly separable from the other member of the genus, G. immaculatus, in morphometricsand meristics. The key characteristics of this species include: first to fourth dorsal-fin spines and pelvic-fin spine with expanded, coarsely serrated tips; pectoral-fin rays 13–14, soft dorsal-fin rays 12.

A new Tyttocharax species from the Güejar River system, near the Macarena Mountains in Colombia is described. This is the first record for the genus from the Orinoco basin. The combination of the following characters distinguish Tyttocharax metae from its congeners: presence of bony hooks on the pectoral and caudal-fin rays; bony hooks on the anal-fin rays larger than those on the pelvic-fin rays; pectoral-fin rays i,5-6,i; presence of three unbranched dorsal-fin rays; absence of an adipose fin; four scales rows between the anal-fin origin and the lateral line; and four scale rows between the pelvic-fin and the lateral line. Ecological characteristics of the habitat of the new species are also presented.

The tropical species of the triglid subgenus Pterygotrigla (Pterygotrigla) are reviewed. Diagnoses, descriptions, and distributions are given for P. ryukyuensis, P. guezei, for two recently described species, P. saumarez and P. gomoni, and one new species. P. cajorarori, described herein. The statuses of the species of the subgenus are discussed and the subgenus is diagnosed. The subgenus lacks a nasal spine and has a short opercular spine, two features that distinguish it from the other two subgenera. The new species, P. cajorarori, has extreme hyperostosis of the head bones and first dorsal fin spines. It has 12+3 pectoral fin rays and is a rare species with few specimens from Japan, Philippines, Australia, and Indonesia.

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).

A new species of trichomycterid catfish, Trichomycterus pascuali, is described from Paranapanema basin and is distinguished from all congeners by the possession of five pectoral-fin rays and the absence of pelvic fin, girdle, and muscles. Additional features further differentiate the new species from the other congeners lacking pelvic fins, T. candidus, T. catamarcensis, and T. tropeiro. The identification of T. pascuali is additionally corroborated by genetic divergence based on DNA-barcode analysis. Osteological and myological data unequivocally support the inclusion of the new species in the Trichomycterinae and molecular analyses justify its allocation to the genus Trichomycterus rather than Eremophilus, a trichomycterine taxon traditionally diagnosed by the lack of pelvic fins. Our genetic analysis further indicates that pelvic fins were independently lost in E. mutisii, T. candidus, and T. pascuali.

A new species of Trimma is described from the islands just off the Thailand coast near Phuket. Trimma ukkriti n.sp. lacks scales on the cheek and opercle, but has ctenoid scales in the midline of the nape, has an elongate second spine of the first dorsal fin which reaches posteriorly to between the base of the spine and the base of the 4th ray of the second dorsal fin when adpressed, 19–20 pectoral-fin rays with 6–13 branched rays in the middle of the fin, an unbranched 5th pelvic-fin ray, which is 48–67% the length of the 4th ray, a U-shaped interorbital trench with no fleshy median ridge, a poorly developed postorbital trench ending at the 5th papilla in row p (which has 6 papillae in total), and row c beneath the eye consists of 6 papillae. When live and freshly collected, the species is very similar in appearance to T. okinawae and T. readerae, with orange to red spots on the head and body.

Knodus shinahota, new species, is described from río Shinahota, a tributary of the upper rio Mamoré basin, Província de Tiraque, Cochabamba State, Bolivia. The new species can be distinguished from all congeners except K. chapadae and K. geryi by having six rows of scales between the lateral line and the dorsal-fin origin (vs 4 or 5 rows of scales in the other species). Knodus shinahota differs from K. chapadae by possessing more rows of scales between the lateral line and the pelvic-fin origin (5 vs 3½ or 4, respectively) and more lateral line scales (38-41 vs 36-38, respectively). It differs from K. geryi by possessing more rows of scales between the lateral-line and the pelvic-fin origin (5 vs 4, respectively); fewer branched anal-fin rays (17-20 vs 15-17, respectively), and by lacking the two symmetric, large, dark, blotches on the basal portions of the caudal-fin lobes that characterize K. geryi.

Pimelodus multicratifer, a new species, is described from the rio Ribeira de Iguape basin. The new species differs from the other Pimelodus species by the following features: 26 to 30 gill rakers on the first branchial arch; a combination of three to six rows of dark spots regularly or irregularly scattered on the flanks and several small dark spots irregularly scattered on the dorsal surface of head, supraoccipital process, and sometimes on the dorsal and caudal fins; striated lips; maxillary barbels reaching between posterior tip of the pelvic-fin rays and posterior tip of the middle caudal-fin rays.

Gobiesox lanceolatus is described from a single specimen collected from 300 meters depth in the Los Frailes submarine canyon in the southwestern Gulf of California. The "Canyon Clingfish" is unique within Gobiesox in having a lanceolate caudal fin, with the central rays longer than those above and below them. It is also distinguished by 14 dorsal-fin rays (first tiny and unsegmented), 11 anal-fin rays, 28 pectoral-fin rays, anus slightly closer to anal-fin origin than to posterior margin of pelvic disc, and dorsal-fin origin in front of vertical from anus. It is most similar to Gobiesox eugrammus, known from Isla Guadelupe, the coast of outer Baja California and southern California. This is the deepest record for a species of Gobiesox and only four other species of clingfishes are known from greater depths.

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.
