Planche 1 issued from : A.A. Al-Kholy in Publs mar. biol. Stn Ghardaqa, 1963, 12. [p.131, Figs.1-4]. As Monostrilla longipes. Very doubtful at the specific level, presumably do belong to the M. hyottoko species-Group.
Female (from Al-Ghardaqa, Red Sea): 1, habitus (dorsal); 2, cephalothorax (lateral); 3, genital spines; 4, P5.

Planche 2 Issued from : A. Scott in The Copepoda of the Siboga Expedition Part I. Siboga-Expeditie XXIX a., 1909. [Pl. LVIII, Figs.3-4]. As Monstrilla longipes.
Female (from off Laiwui, N Ceeram Sea): 3, habitus (dorsal); 4, P5.

Nota:
- Cephalic segment much inflated just behind the frontal margin; it is considerably longer than the posterior part of the body.
- Frontal margin wide and broadly rounded.
- Exoskeleton of the cephalic and first three thoracic segments marked by fine reticulations that are beset with minute spines.
- Abdomen 3-segmented.
- Genital segment sub-quadrangular in outline; slightly contracted at the middle where it is traversed by a distinct suture; the distal ends provided with small points. The segment is one and two-third times longer than the combined length of the next two segments. Its length rather shorter than the united length of the next two segments and caudal rami.
- The 2nd and 3rd segments sub-equal in length. The distal end of the 3rd segment is decidedly expanded.
- Caudal rami 3 times longer than the anal segment, each ramus with 1 outer marginal seta and 5 apical setae; the middle apical seta shorter than the others.
- A1 4-segmented and equal to two-fifths of the length of the cephalothorax.
- P5 long and slender and without apical division; the apex with 2 moderately strong setae.
