- 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. Key-words. - Gobioidei - Sicydiinae - Sicyopus chloe - New Caledonia - Freshwater - New species. |
