Species of grenadier fishes (Order Gadiformes) in Taiwan are reviewed. The species list of Shao et al. (2008) is revised. A total 71 species in 21 genera and 3 families is recognized, including 5 species that are tentatively identified and 5 species, Coelorinchus hexafasciatus, C. cf. macrorhynchus, C. cf. notatus, Hymenocephalus papyraceus, and Ventrifossa sazonovi, that are first records for Taiwan. Ventrifossa fusca is recognized as a junior synonym of V. misakia. Keys to families, genera and species are provided. Species descriptions are based mainly on Taiwanese specimens but supplemented with specimens from various other sources. Figures of species firstly reported by Shao et al. (2008) are provided.

Nezumia infranudis is redescribed from the holotype and an additional specimen collected from the Timor Sea at a depth of 610–690 m. It belongs to the Nezumia spinosa group (herein defined) and is most similar to the Indo-West Pacific N. spinosa. Nezumia infranudis is distinguished from other congeners by the following combination of features: pelvic-fin rays 11; body scales covered with long, reclined, needle-like spinules densely scattered over exposed portion; underside of head almost completely naked, with prominent sensory pores; teeth in broad bands in both jaws; snout long (31–32% of head length (HL)), protruding well beyond upper jaw; second spinous ray of first dorsal fin greatly elongated (height of first dorsal fin 158–166% HL); no prominent dark band encircling trunk; first dorsal fin almost uniformly blackish. The first report of N. infranudis in the Indian Ocean represents the only confirmed record of the species since its original description. A key to species of the N. spinosa group is provided.

A rare sandperch, Parapercis fuscolineata Fourmanoir, 1985, is reported for the first time from Japan, based on a single specimen (36.8 mm SL) collected from Tosa Bay, Kochi Prefecture, Shikoku Island, at a depth of 200–203 m. This species was previously known only from the Philippines (type locality) and the tropical southwest Pacific region (Solomon Islands, Vanuatu, and New Caledonia); thus the Japanese specimen represents the northernmost record of the species. The unique coloration of P. fuscolineata, including a dark continuous stripe extending from the hind rim of the orbit to the caudal peduncle, a large black ocellus on the upper caudal-fin base, and about 12 diagonal yellowish bars on the lower half of the body, readily distinguishes this species from its congeners. The Japanese specimen is fully described, with color photographs of the fresh specimen. A new Japanese name, “Kuroobi-toragisu”, is proposed for P. fuscolineata.
