A new species of pipefish, Syngnathus chihiroe sp. nov., (Syngnathidae), is described on the basis of a single specimen collected off Yakushima Island (East China Sea), southern Japan in a depth of 160–162 m. The new species is readily distinguished from all congeners by the combination of the following characters: dorsal-fin rays 38, pectoral-fin rays 17, trunk rings 18, tail rings 40, subdorsal rings 3.25 + 10.0 = 13.25, head length 8.7 in standard length, snout length 2.3 in head length and snout depth 3.7 in snout length. The new species is similar to Syngnathus schlegeli Kaup 1853, the only other northwestern Pacific Ocean congener, characterized by dorsal-fin rays 30–47, trunk rings 18–20 and tail rings 38–46. However, it differs from S. schlegeli in having a greater number of pectoral-fin rays (17 in the former vs. 11–15 in the latter), and a short deep snout (snout length 2.3 in head length and snout depth 3.7 in snout length vs. 1.6–2.0 and 5.6–11.3, respectively).

A new species of ptereleotrine dartfish, Navigobius asayake, is described based on four specimens (45.0–52.1 mm in standard length: SL) collected from off the Satsuma Peninsula and Tanegashima island, Kagoshima, southern Japan. It is distinguished from other congeners by the following combination of characters: second dorsal-fin rays I, 18–19; anal-fin rays I, 19; pectoral-fin rays 21–22; gill rakers 5–6 + 13–15; head length 25.1–26.4% SL; eye diameter 8.6–10.0% SL; pelvic-fin length 15.2–16.1% SL; and a well-developed yellow stripe extending from behind upper part of eye to beneath first dorsal fin.

A new species of Ituglanis is described from rio Iratapuru, near the rio Jari, Amapá, Brazil. The new species is distinguished from all congeners by the reduced number of post-Weberian apparatus vertebrae (36 or 37); the low number of paired ribs (2); the low number of interopercular odontodes (12–15); the number of branchiostegal rays (7 or 8); the presence of elongated fontanel in parieto-supraoccipital; the pectoral-fin rays (i,5); head length (18.9–25.0); and the presence of pores supraorbital s1, infraorbitals i1 and i3 of the laterosensory system. The new taxon has a reduced body size and fully ossified skeleton, but does not display a large number of paedomorphic traits compared to congeners. Comments about taxonomy and intrageneric comparisons are made, and paedomorphic in Ituglanis is discussed. Thoughts about conservation of the new species are presented.

A new species of the genus Osteobrama is described from the Mahanadi River, Tikarpada, Angul District, Odisha state, India. Osteobrama tikarpadaensis, new species, differs from its congeners in having two pairs of minute barbels; iii–iv unbranched dorsal-fin rays with 25–33 serrae on the last unbranched ray; 15–16 branched pectoral-fin rays, and 25–27 branched anal-fin rays. The status of Osteobrama dayi is discussed and shown to be a valid species. A key to the species of the genus is provided.

Plectranthias cruentus new species is described from the holotype and two paratypes collected off Ball’s Pyramid and a paratype from Lord Howe Island. It resembles P. pelicieri Randall & Shimizu 1994 in live coloration and most morphological details, including absence of predorsal scales anterior to the supratemporal commissure, but differs in having the fifth or sixth (versus third) dorsal-fin spine longest, at least some pectoral-fin rays branched (versus all unbranched), and inconspicuous (versus distinct) serrations on the interopercle. It also differs in live coloration details.

A New Species

A new species of Propimelodus from the middle course of the rio Araguaia is described. Propimelodus araguayae, new species, can be distinguished from its congeners in having a conspicuous black dot on the base of the dorsal-fin rays (vs. a different pattern), large eyes (29.7-34.8% of head length and 62.7-74.7% of snout length vs. 14.5-21.1% and 31-44% in P. caesius and 9.5-19.7% and 17-38% in P. eigenmanni), anal-fin lobe present (vs. absent), premaxillary bone with three irregular rows of teeth (vs. 4-5 in P. caesius and 5-8 in P. eigenmanni), tip of anterior lateral process of basipterygium at the same level as the tip of the anterior medial process (vs. anterior lateral process extending beyond the tip of the anterior medial process), total number of vertebrae (43-44 vs. 47-48 in P. caesius and 45-46 in P. eigenmanni) and total number of gill rakers (28-33 vs. 20-23 in P. caesius and 19-20 in P. eigenmanni). This new species is possibly endemic to the middle course of the rio Araguaia.

A new species of the triangular batfish genus Malthopsis Alcock, 1891 is described on the basis of 9 specimens collected from off Taiwan. The new species belongs to a species group with ventral surface covered by numerous small prickle-like bucklers. It differs from the members in this species group in having ventral surface entirely covered with tiny bucklers; principal bucklers on dorsal surface relatively tall, few in number and loose in arrangement; subopercle dull without enlarged forward-directed spine; rostral spine directed forward horizontally; 5 dorsal-fin rays and 12 pectoral-fin rays; and posterior tip of appressed anal fin not reaching caudal-fin base. Two specimens of Malthopsis tiarella Jordan, 1902 collected from Taiwan are recognized and its diagnosis is discussed.

Aenigmachanna mahabali, a new species of troglophilic snakehead is described on the basis of a single specimen recovered from a well in Kerala, India, over 200km south of the type locality for the only known species in the genus. The new species can be distinguished from its congener in possessing fewer dorsal fin rays (53 vs 56-57), fewer total vertebrae (61 vs 64), fewer scales in lateral series (76 vs 83-85) and in the pectoral-fin rays being extended beyond the margin of the membrane into filaments.

The genus Homalopteroides Fowler 1905 is resurrected and distinguished from the genus Homaloptera van Hasselt 1823based on a combination of characters including a unique mouth morphology, dorsal-fin origin over pelvic fin,≤60 lateral-line scales, and≤30 predorsal scales. Species included in Homalopteroides are H. wassinkii (Bleeker 1853), H. modestus(Vinciguerra 1890), H. rupicola (Prashad & Mukerji 1929), H. smithi (Hora 1932), H. stephensoni (Hora 1932), H. weberi(Hora 1932), H. tweediei (Herre 1940), H. indochinensis (Silas 1953), H. nebulosus (Alfred 1969), H. yuwonoi (Kottelat1998), and possibly H. manipurensis (Arunkumar 1999). Homalopteroides modestus (Vinciguerra 1890) is a poorlyknown species that was originally described from the Meekalan and Meetan rivers of southern Myanmar. It occurs in theSalween, Mae Khlong, and Tenasserim basins, and can be distinguished from all other species of Homalopteroides by thecombination of caudal-fin pattern (black proximal and distal bars, median blotch), 15 pectoral-fin rays, pectoral-fin lengthgreater than head length, 5½–6½ scales above and 5–6 scales below the lateral line (to the pelvic fin), 39–44 total lateral-line pores, no axillary pelvic-fin lobe, pelvic fin not reaching anus, orbital length less than interorbital width in adult, and maxillary barbel reaching to or slightly past the anterior orbital rim.

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.
