Morphological comparison of species closely related to Acartia tranteri.
Data for A. ensifera, A. jilletti, A. simplex, and A. tranteri are taken from Bradford (1976).
TL: total length (from the tip of the caudal rami to the front of the head); Th6S: mean number of spines on the thoracic segment 6; GC: Presence/absence of spinules on the posterior dorsal margin of the genital complex; GCP: presence/absence of protuberances posterior to the genital apertures on the female genital complex; LP5 a.s.: relationship of length of the anterior spine of the left male P5 to the posterior spine (see Bradford, 1976); LGC: length of the female genital complex along the dorsal midline; WGC: maximum width of the female genital complex in dorsal view; LCR: length of right caudal ramus along outer margin (measured to insertion of outer terminal seta in dorsal view); WCR: width of right caudal ramus at base in dorsal view; Th6: presence/absence of hairs on the posterior ventral margin of thoracic segment 6; C: presence/absence of spinules on the posterior lateral face of genital complex; U2: both sexes, as GC, but urosome segment 2; U3: males, as GC, but for urosome segment 3; U4: males, as GC, but for urosome segment 4; p: presence; a: absence; for the characters C, GC, Th6, U2, U3 and U4 percentage of occurrence is given.

Female: a, urosome (lateral); b, idem (dorsal).
Nota: Last thoracic segment (Th6) with 4-7 spines (average 5), and with fine hairs on ventroposterior margin. Mean length:width ratio of genital complex, in dorsal view, 1.10. Lateral faces of genital complex with rows of denticles always extending on to posterior half of segment. Mean length : width ratio of caudal ramus 2.72. Dorsoposterior margin of 2nd, 3rd and 4th urosome segments with row of denticles.

Male: c, urosome (dorsolateral).
Nota: Last thoracic segment (Th6) with 3-6 dorsolateral spines. Length : width ratio of caudal ramus 1.66

Scale bars: 0.100 mm.
