Acartia (Hypoacartia) macropus  Cleve, 1900   (F,M)
Cleve, 1900 c (p.3, figs.F,M); Steuer, 1923 (p.15, figs.F,M); Bradford-Grieve, 1999 (N°181, p.6, figs.F,M).
Species Acartia (Hypoacartia) macropus - Plate 1 of morphological figuresissued from : A. Steuer in Arb. zool. Inst. Innsbruck, 1923, 1 (5). [p.14, Figs.54-57]. After Cleve, 1900.
Female: 54, habitus (dorsal); 56, P5.

Male: 55, habitus (dorsal); 57, P5.

Species Acartia (Hypoacartia) macropus - Plate 2 of morphological figuresIssued from : J.M. Bradford-Grieve in ICES Identification Leaflets for Plankton N°181, 1999 [p.13, Figs.18a-f].
Female: a, dorsal); b-c, P5.
Nota: Last two somites of prosome with 2, asymmetical finger-like processes, left one straight and placed more posteriorly than right curved process.
Genital double-somite 3 times as long as urosomite 2, which is equal to urosomite 3.
Longest seta on caudal rami exceeds urosome in length; all setae of equal thickness.
Caudal rami nearly twice as long as broad. Prosome 3 times longer than broad.
P5 terminal spine very short and apparently fused with basis; its interior margin is denticulate.

Male: d, urosome (dorsal); e-f, P5 (L = left leg; R = right leg).
Nota: Lateral corners of prosome rounded; margin of last somite smooth, without small spines.
Right exopodal segment 2 of P5 longer than broad, inner projection arises from proximal half of segment, exopodal segment 3 elongate with a very small terminal claw.
