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.

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.

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.

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 Hypostomus Lacépède is described from the rio Paraguaçu basin, Bahia State, Brazil. The new species is distinguished from its congeners by having black and conspicuous dots on a pale background, which are similar in size on the head, trunk, and fins, along with ventral surface of head and abdomen naked or the latter plated exclusively on its anterior portion, absence of ridges on head and trunk, and caudal-fin lobes relatively similar in length. The new species further differs from the sympatric H. chrysostiktos by having seven branched dorsal-fin rays instead of 10-11 and represents the eleventh siluriform species endemic to the rio Paraguaçu basin.

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.

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).

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.
