Species Scolecithricella globulosa - Plate 1 of morphological figuresissued from : T. Park in Antarct. Res. Ser. Washington, 1980, 31 (2). [p.44, Fig.8]. As Scolecithricella schizosoma.
Female: a, habitus (lateral right side); b, forehead (lateral); c, last thoracic segment and urosome (lateral right side); d, genital segment (lateral left side); e, rostrum (anterior); f, A2; g, Md; h, Mx1; i, distal part of Mx2; j, Mxp; k, P1 (anterior); l, P2 (posterior); m, P3 (posterior); n, basipod of P4 (posterior); o, P5 (posterior).


Species Scolecithricella globulosa - Plate 2 of morphological figuresissued from : T. Park in Antarct. Res. Ser. Washington, 1980, 31 (2). [p.45, Fig.9]. As Scolecithricella schizosoma.
Male: a, habitus (lateral left side); b, forehead (lateral); c, rostrum (anterior); d, A2; e, Md; f, Mx1; g, distal part of Mx2; h, Mxp; i, P2 (posterior); j, P5 (anterior).


Species Scolecithricella globulosa - Plate 3 of morphological figuresIssued from : K.A. Brodskii in Calanoida of the Far Eastern Seas and Polar Basin of the USSR. Opred. Fauna SSSR, 1950, 35 (Israel Program for Scientific Translations, Jerusalem, 1967) [p.272, Fig.180].
Female (from NW Pacific): habitus (dorsal and lateral left side); R, rostrum; Do, urosome (dorsal); Mp1, Mx2; S5, P5.


Species Scolecithricella globulosa - Plate 4 of morphological figuresIssued from : O. Tanaka in Japanese J. Zool., 1937, VII, 13. [p.260, Fig.10]. As Scolecithricella abyssalis specimen mutilated.
Female (from coast of Heda, Japan): a, urosome; b, distal part of Mx2; c, P5.

Nota: A1 21-segmented; segments 8-9-10, 20-21 and 24-25 fused.
Terminal segment of Mx2 bears 3 long vermiform filaments and 5 amalliform setae.
Mxp small; 1st basal segment carries, besides usual setae, 2 vermiform filaments and 1 amalliform seta.
P5 similar to the figure given by Giesbrecht (1892) for S. abyssalis, but the small spine on the middle of the outer margin of the segment was not observed on the left leg.
Remark from C.R.: Note also the difference in the shape of the outer margin.

Rem.: meso-bathypelagic.
Probable in this genus.
For Park (1980, p.46) this species is closely related to S. dentata. Park & Ferrari (2009, p.178) do not admit the synonymy between Scolecithricella schizosoma and S. globulosa, the former is mainly an antarctic and sub-Antarctic form and the latter sub-Arctic.
