“Azygocypridina Sylvester-Bradley, 1950
TYPE-SPECIES.—Crossophorus imperator Brady, 1880.
This genus is represented by two species in the study area, A. imperator (Brady) and A. africanus (Stebbing, 1901). A third unnamed specimen has been reported from the Tasman Sea just outside the study area (34°03'S, 151°31'E) by McKenzie (1968a).
DIAGNOSIS OF GENUS.—Endopodite of adult male 2nd antenna reflexed; outer lobe of 3rd exopodite joint of 5th limb with 2 bristles; 2 or more short claws present between some large claws of furca.
DISTRIBUTION.—Although seldom collected in large numbers, the genus is widely distributed. The northernmost limit of its range is in the North Atlantic, west of Ireland (55° 11'N, 11 °31'W). Its southernmost limit is 40°28'S in the vicinity of New Zealand. Members of the genus have been collected at bottom depths of 156-2633 m.”
