Résumé

Sicyopus (Smilosicyopus) chloe n. sp., a carnivorous freshwater goby, is described on the basis of 22 specimens collected from high gradient streams on the eastern coast of North Province, New Caledonia. It differs from most Sicyopus species in having canine teeth in both upper and lower jaws, and the absence of labial teeth projecting horizontally from the lower jaw. It differs from other species of the subgenus Smilosicyopus by a combination of characters that include 4-7 blackish spots on each side of nape, a broad blackish V-shaped mark ventrally on head being most prominent in males, 14-16 scales in zigzag series and strongly differentiated sexually dichromatism colour patterns. All other species of Sicyopus (Smilosicyopus) have sexual dichromatism poorly developed with males being only slightly more dusky than females.
