 issued from : T. Park in Crustaceana, 1975, 28 (3). [p.293, Fig.2]. Male: A-B, habitus (dorsal and lateral, respectively); C, P5 (anterior); D, distal part of left P5 (anterior); E, idem (posterior). Nota: P5 consisting of a small, uniramose left leg and a well developed, biramose right leg; right basipod reaching about middle of 1st exopodal segment; right endopod unsegmented, tapering into a curved spiniform process, with a prominent tooth-like process close to proximal end; right exopod 2-segmented, proximal segment with a large tooth-like process at a level immediately posterior to the tooth-like process on endopod; distal segment tapering into a curved spiniform process, with its internal margin finely serrated. In left leg of P5 endopod lacking; exopod 3-segmented, last segment small with 3 or 4 small tooth-like processes distally, and together with distal part of 2nd segment (immovable finger), forming a small chela; immovable finger of the chela slightly longer than movable finger (3rd segment).

 issued from : J.C. von Vaupel Klein in Crustaceana, Supplt 9, Studies on Copepoda, III, 1984. [p.76, Fig.14, i]. Female: i, arrangement of spinules on the lateral tubercle of ebdopod of P1 (note: spinules approximately equal size, and arranged in a close group). Scale bar 0.067 mm.

Female: i, fusion of exopodal segments 1 and 2 of P1 (left appendage, posterior view). Nota: Only very faint indications of the former suture are occasionally found in individual specimens of most species of Euchirella, and then mainly on the anterior face of the combined segment. Scale bar 0.1 mm.

Scale bar: 0.2 mm.
