Epacteriscoidea Fosshagen, 1973

Diagnosis: Plesiomorphic calanoid copepods with underlying pattern of full development of arthrodial membranes between body somites and limb segments, with some exceptions: antennule of female up to 27- segmented, ancestral segments XIX, XX, and XXIII usually without asthetascs; male antennule always geniculate on right and tendency for ancestral segment XXV to have distoanterior process. Male and female mouthparts identical. Antenna exopod nine-segmented, segments I–VIII with one seta each. Maxilliped endopod segment V nearly always with outer border seta (except Edaxiella ); swimming legs 1–5 with both rami usually three-segmented; legs 1 and 2 exopod segment 3 with two or three outer border spines, leg 3 exopod segment 3 with two or three outer border spines, legs 4 and 5 (female) with two or three outer border spines.
