Abstract
Paraulopus brevirostris, P. filamentosus, P. japonicus, P. legandi, P. maculatus, and P. oblongus are redescribed. All species are included in the Paraulopus oblongus group, characterized by having no supraocular ridge, 2.5–3.5 scales above the lateral line, and small adult body size (70–150 mm SL). In addition, P. atripes, from the Indian Ocean, is described as a new species of the P. oblongus group, being defined by the following combination of characters: small antrorse dentary process on chin; eye directed laterally; pelvic fin black in males; caudal fin white; 32–34 gill rakers; 45–46 pored lateral-line scales; and 3.5 scales below lateral line. Paraulopus albimaculatus is regarded as a junior synonym of P. brevirostris, based on examination of type specimens. A key to species in the P. oblongus group is included.
