Issued from : A. Scott in
The Copepoda of the Siboga Expedition Part I. Siboga-Expeditie XXIX a., 1909. [Pl. LVII, Figs.7-8].
Female (from off Pulu Kawassang, Paternoster Islands): 7, habitus (dorsal); 8, P5.
Nota: Cephalic segment evenly rounded in the frontal portion and very slightly contracted at the distal end; it is slightly longer than the posterior part of the body.
Frontal margin very narrowly rounded and slightly cleft.
Genital segment sub-quadrangular in shape and traversed by a distinct suture rather in front of the middle; its length equal to twice the combined length of the next two segments; it is rather shorter than the united length of the next two segments and caudal rami.
The 2nd and 3rd segments very short and nearly equal length.
Caudal rami 3 times longer than the anal segment; each ramus with 1 outer marginal seta and 5 apical setae.
A1 3-segmented, equal to one-third of the length of the cephalic segment.
P5 rather slender and distinctly bi-lobed. The inner lobe narrower than the outer lobe and does not extend beyond the end of it; apex with 1 seta; the outer lobe with 3 setae.
This species comes very near Monstrilla grandis
in general appearance, and in the shape of P5. The chief difference is in the inner lobe of P5; Giesbrecht's figure shews the inner lobe of P5 M. grandis
with 2 setae, instead 1 in the Siboga's specimens.
