Brtek (1966) divided the genus Eubranchipus into several subgenera based upon various characters. The validity of these subgenera needs to be re­evaluated. Brtek’s subgenus Creaseria, however, is a preoccupied name (ICZN, 2000), having been originally used by Holthuis in 1950 to name a South American genus of fresh­water Palaemonid shrimps. Brtek (1966, 1967) defined this Eubranchipus sub­genus to include: Eubranchipus oregonus Creaser, 1930; E. neglectus Garman, 1926; E. holmani (Ryder, 1879), and; E. moorei Brtek, 1967. Brtek (1964, 1965, 1966) erected the family Linderiellidae to encompass Linderiella and Dexteria Brtek, 1965, and the family Artemiopsidae Brtek, 1966 for Artemiopsis, which were later subsumed back into the Chirocephalidae by Belk (in Martin & Davis, 2001) and (with the Polyartemiidae) Weekers et al. (2002). The family is redefined here.

Abstract

The second antenna of male anostracans in the genera Polyartemia and Polyartemiella are described as polyramous, unsegmented structures. This is in sharp contrast to males of all other anostracan genera, which bear variously ornamented, uniramal second antenna that are secondarily two­segmented. By following the development of the second antenna of male P. h a z e n i through various instars, I found that the posterior ramus is the actual second antenna, unsegmented, and that the remaining rami represent a rigid antennal appendage, a structure common to the majority of genera within the Chirocephalidae. In addition, the family Chirocephalidae is redefined, the genus Galaziella is synonymized with Chirocephalus, and a key to genera and a checklist of described species is provided.
