Review of the Fishes of the Kuhlia (: Kuhliidae) of the Central Paci®c1

John E. Randall and Helen A. Randall2

Abstract: Ten of ®shes of the genus Kuhlia are recognized from Palau to Hawai`i in the North Paci®c and from Fiji to in the South Paci®c: K. malo (Valenciennes) from fresh water in the Society Islands; K. marginata (Cuvier) from fresh water in the western Paci®c, east to Kosrae, Caroline Islands, and Fiji; K. mugil (Forster) (K. taeniura is a synonym) from most of the Indo-Paci®c (not the Hawaiian Islands) and the tropical eastern Paci®c; K. munda (De Vis) from fresh and brackish water in Fiji, Vanuatu, New Cale- donia, and Queensland (K. proxima Kendall & Goldsborough and K. bilunulata Herre are synonyms); K. nutabunda Kendall & Radcliffe from Easter Island; K. petiti Schultz from the Phoenix Islands, Malden Island, and the Marquesas Islands (Dules taeniurus marquesensis Fowler is a synonym); K. sandvicensis (Steindachner) from the Hawaiian Islands and other islands of the central Paci®c; K. rupestris (LaceÂpeÁde) from fresh water from East Africa to Samoa (K. caerulescens Regan from the is a new synonym); K. salelea Schultz from fresh water in the Samoa Islands; and K. xenura ( Jordan & Gilbert) from the Hawaiian Islands, with a mistaken type locality of El Salvador, Central America. The name K. sandvicensis has long been used for the common endemic species in the Hawaiian Islands; however, the original description leaves little doubt that it should apply to the species widely distributed in the central Paci®c and only recently discovered in Hawai`i; it has usually been misidenti®ed as K. marginata. The endemic Hawaiian species therefore takes the only available name, K. xenura ( Jordan & Gilbert). differs from K. xenura in having a smaller eye (3.0±3.45 in head length, compared with 2.55±2.95 for K. xenura), straight dorsal pro®le of the head of adults (concave in xenura); usually 14 pectoral-®n rays (usually 15 in xenura), usually 50 lateral-line scales (usually 49 in xenura), gill rakers 38±43 (35±39 for xenura), and a dark reticular pattern dorsally on the head in life.

The ®shes of the family Kuhliidae are pally on planktonic crustaceans. These ®shes moderately deep-bodied and compressed, are generally silvery, often with dark mark- with two opercular spines, a deeply notched ings on the caudal ®n, the basis for the com- dorsal ®n of 10 spines and 9±13 rays, and a mon name ¯agtails. The Hawaiian name scaly sheath at the base of the dorsal and anal aÅholehole is also sometimes used beyond ®ns. They have large eyes and are primarily Hawai`i. The family consists of a single ge- nocturnal, at least as adults, feeding princi- nus, Kuhlia, the species of which occur in tropical and subtropical waters of the Indo- Paci®c region, and one is also found in the 1 Manuscript accepted 12 November 2000. tropical eastern Paci®c.
