Two new species of Bleekeria Günther, 1862 are described from specimens collected in the Andaman Sea off the coast of Myanmar during bottom surveys conducted by the R/V Dr Fridtjof Nansen in 2015 and 2018. They are distinguished from each other and from congeners by a combination of morphological and meristic characters as well as fin coloration and genetic variance. Bleekeria albicauda sp. nov. has pelvic fins, 40–41 dorsal-fin rays, 54–55 total vertebrae, no teeth in jaws, 4 scale rows between dorsal-fin origin and lateral line, a single row of about 10 scales on mid-upper part of opercle, scales on central part of body clearly shorter than their height, caudal fin with white upper and lower lobes when fresh (unique within the genus). Bleekeria nigrilinea sp. nov. has no pelvic fins, 37–39 dorsal-fin rays, 49–50 total vertebrae, 2½ scale rows between dorsal-fin origin and lateral line (the smallest count within the genus with B. estuaria of Mozambique brackish water), 5–6 scales on mid-upper part of opercle arranged in a single row, scales on central part of body clearly longer than their height, upper and lower margins of caudal fin black when fresh (unique within the genus). The COI gene sequences of the two new species showed clear genetic divergence (pairwise K2P, >10 %) from Bleekeria estuaria Randall & Ida, 2014 and Bleekeria mitsukurii (Jordan & Evermann, 1902). A key to the species of Bleekeria is provided.

Two new species of genus Leporinus from the Araguaia-Tocantins system, Amazon, Brazil, are described. Leporinus unitaeniatus n. sp. is distinguished from the remaining species of this genus by the presence of a conspicuous longitudinal dark brown bar along the lateral line on the flanks, and Leporinus geminis n. sp. is distinguished by an inconspicuous dark bar combined with three large and vertically elongated brown blotches on the trunk; the first on the dorsal fin region, the second anterior to the adipose fin and the third on the caudal peduncle. Both are medium-sized species of the genus (up to 150 mm SL) and share the following combination of meristic characters: 4 teeth on each premaxillary and dentary; 40-43 scales in the lateral line, 6/I/5 scales on the transversal line, and 16 series of scales around the caudal peduncle. L. unitaeniatus n. sp. has a sub-terminal mouth and tooth series formed by incisive-like elongated teeth frontally turned and with only a straight cutting edge decreasing in size like the steps of stairs from the teeth pair of symphysis. Leporinus geminis n. sp. has a sub-inferior mouth and the tooth series shaped by large incisive-like teeth forming an arched cutting edge, decreasing in size from the symphysal pair of teeth.

A New Species

A new species of Characidium Reinhardt, 1867 endemic to tributaries of the upper rio Paraguaçu in the Chapada Diamantina, Bahia, Brazil, is described. The new species can be distinguished from its congeners except C. bahiense, C. bimaculatum, C. laterale, C. nana, C. nupelia, and C. xavante, by having a conspicuous peduncular blotch in addition to the basicaudal spot on the base of the middle caudal-fin rays. Among other features, the new species differs from C. bahiense, C. laterale, C. nana, C. nupelia, and C. xavante by having a complete lateral line with 32–36 perforated scales (vs. lateral line short, with 9–11 perforated scales), and from C. bimaculatum by the body pigmentation pattern, with secondary bars present (vs. absent), total bars 11–16 (vs. 10–12), peduncular blotch rounded (vs. horizontally elongated), and mature males not having a darker dorsal fin (vs. proximal third of dorsal fin darker in mature males). Characidium bimaculatum, a poorly known species from Northeastern Brazil, is redescribed.

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.
