|Title||A revision of the genus Candacia (Copepoda: Calanoida) with an annotated list of the species and a key for their identification|
|Abstract||The genus Candacia 2) was erected by Dana (1846) for certain copepods found in collections obtained by the U. S. Exploring Expedition of 18381842. When the species referable to this genus were first described three years later, Dana (1849) changed the generic name to Candace. Giesbrecht (1892) established the family Candacidae to accommodate Candace but six years later Giesbrecht & Schmeil (1898) used Dana's first proposed generic name, Candacia, and accordingly changed the family name to Candaciidae.|
These latter two names have been used by most authors since about 1900.
I wish to thank Dr. W. Vervoort for reading and criticizing the manuscript, Miss Abigail Hooper for checking literature references and for preparing distribution charts, and my wife, Joan, for help in preparing the illustrations. I also wish to thank Drs. T. E. Bowman and A. Fleminger for criticizing the key.
DIVISION OF THE GENUS AND A LIST OF THE SPECIES
Sars (1903) recognized that two types of males were included in the species then referable to Candacia and he indicated that the genus could probably be divided into two genera. Twelve species have subsequently been described all of which are referable to one of the types recognized by Sars.
The genus is here divided into two genera, Paracandacia nov. gen. and Candacia s. s. the diagnoses of which are given below.
Paracandacia nov. gen.
TYPE SPECIES. Candace truncata Dana, 1849 (= Paracandacia truncata).
Since no types were mentioned by Dana and none of his specimens is apparently extant a female specimen collected in the Pacific Ocean (oo°35'N 170°11'E) and deposited in the U. S. National Museum (Cat. No. 107600) is
