A new species of Pimelodella is described from western Andean tributaries of the Orinoco River basin. The new species differs from all congeners by a unique set of characters that includes long maxillary barbel, surpassing the dorsal lobe of the caudal fin; relatively short adipose fin (32.8–36.4 of SL); 40–42 total vertebrae; posterior margin of pectoral-fin spine with 12–18 retrorse dentations along basal two thirds; laterosensory canal foramina of dentary and preopercle large and externally conspicuous; a brown faint and narrow midlateral stripe extending from the pseudotympanum, fading posteriorly along the caudal peduncle, and ending as a spot at the caudal-fin base; and dorsal-fin base darkly pigmented, from spinelet to posteriormost interradial membrane. Taxonomic status of P. pallida and presence of P. cruxenti in Colombia are also discussed.

Schindleria macrodentata sp. nov., a new species of the paedomorphic gobiid fish genus Schindleria, is described from the Malay Archipelago. The two specimens were collected in 1929 during the “Dana Expedition” in the Molucca Sea between Sulawesi and Halmahera islands (00°29′N, 125°54′E) (Indonesia) and in the Sulu Sea close to Panay Island (11°43’N, 121°43′E) (Philippines). The new species is characterized by a slender body (body depth at pectoral fin base 3.6–3.7 % of SL and at anal fin origin 3.9–4.8 % of SL), a long second dorsal fin (first dorsal fin absent) originating distinctly anterior to the origin of the anal fin (predorsal length 61.8–65.2 % of SL and preanal length 71.7–75.8 % of SL), a short tail (from anus to tip of longest caudal fin ray) (22.1 % of SL), 19–20 dorsal fin rays and 10 anal fin rays, first anal fin ray below 9th dorsal fin ray, few large, widely spaced teeth in the upper and the lower jaws (7 on the premaxilla and 6 on the dentary), an elongated pectoral radial plate (length 3.7–4.5 % of SL) and, in the caudal skeleton, a procurrent ray with an additional spiny process at its base. No distinct urogenital papilla and no pigmentation on body are developed. In this study we present three morphological traits until now not considered as diagnostic characters for Schindleria, the shape of the pectoral radial plate, the shape of the last procurrent caudal spine and the shape of the arch formed by the lower jaw. We also discuss the caudal-fin skeleton of Schindleria, a character developing beyond the larval stages. The record of S. macrodentata is the first of the genus Schindleria for Indonesia and, at more than 100 km distant to the next shore, it is the first offshore record of a Schindler's fish.

Thryssocypris wongrati, a new species of cyprinid from the Chao Phraya basin, Thailand, is distinguished from all otherspecies of Thryssocypris by having a combination of the origin of the dorsal fin behind the origin of the anal fin, 37–40lateral-line scales, 16 circumpeduncular scales, and a dark spot at the base of the caudal fin. Thryssocypris wongrati oc-cupies the lower part of the Chao Phraya basin where it has been recorded from irrigation canals in Sing-Buri up to the most northern part of the basin in the Nan River in Phitsanulok Province.

A new species of Creagrutus is described from the Amazonian Piedmont, Colombia. The new species can be distinguished from congeners by presenting the following unique combination of characters: a dark mid-lateral stripe starting at anteriormost scale of lateral line, a vertically elongated humeral blotch, absence of dark blotches on dorsal fin and at base of middle caudal-fin rays, a triangular dentigerous surface of the premaxilla, 5–6 dentary teeth, and 11–12 predorsal scales. Comparisons with congeners distributed in the piedmont region of Río Caquetá basin are presented and its relationships among species of Creagrutus is inferred from the available phylogenetic framework.

A New Species

Barilius signicaudus, a new species of cyprinid fish from the Khwae Noi and Khwae Yai branches of the Maeklong River,western Thailand, is described. It is characterized by the combination of a large, elongated blotch at the caudal-fin base(blotch is formed by the fusion of the large caudal spot at the fleshy end of the caudal base and the last vertical bar on theflank) that extends about 1/3 of the distance from the caudal-fin origin beyond the last scale on the caudal base to the mar-gin of the caudal fork; an anal-fin origin opposing the 2nd–4th branched dorsal-fin rays; eight scale rows above the lateralline; dark pigment on the dorsal fin concentrated mainly along the margins of the rays; 36 or more precaudal lateral-linescales; and small dentary tubercles. This species has previously been identified as Barilius pulchellus and Barilius orna-tus. Barilius pulchellus has no, or a small caudal spot, a dorsal fin with dark pigments concentrated in the middle of theinterradial regions, and much larger dentary tubercles. Barilius ornatus and similar species have an anal-fin position thatopposes the 5th–7th branched dorsal-fin rays (rarely the 4th), or does not overlap with them at all, and have no, or small caudal spots.
