Species Scolecithricella minor - Plate 10 of morphological figuresissued from : W. Vervoort in Verh. K. ned. Akad. Wet., Afd. Natuurk., 1951, (Sect. 2) 47 (2). [p.97, Fig.51]. As Scolecithricella glacialis.
Male (from 64°31'S, 10050'W): a-b, habitus (lateral and dorsal, respectively; rostrum on ventral aspect).
According to Vervoort (1951, p.96) Scolecithricella glacialis has originally been described by Giesbrecht (1902) from female specimens. The species, as is apparent from its description and figures, differs only slightly from Scolecithricella minor (Brady, 1883), the most obvious charcters are the shape of the postero-lateral thoracic border (broadly rounded in minor, slightly produced and angular in and slight differences in the shape of P5. The present males attributed to glacialis, measure 1.34-1.35 mm, agree better with the length of the female.
Nota: Proportional lengths of cephalothorax and abdomen as 65:26. Head and 1st thoracic segment, 4th and 5th completely fused ( the back shows a weakly indicated line, which may represent a rudimentary line of separation between the cephalon and the 1st thoracic somite). Two fine filifom rostral appendages present. Abdomen 5-segmented, anal segment completely telescoped into 4th urosomal somite; 1st urosomal somite produced on the left side; proportional lengths of urosomal somites and caudal rami 11:30:19:23:4:13 = 100. Caudal rami twice as long as wide, each ramus with 4 marginal setae, allsetae plumose,; the outer edge of each ramus haired.

Male: a, urosome and P5 (dorsal); b, idem (lateral); c, P5 (rt = right foot, lt = left foot); d, right A1.
Nota: A1 19-segmented (8th-13th segments completely fused, 14th segment imperfectly separated from the preceding, as also the 15th from the 16th and the 24th from the 25th). In structure the P5 resemble those of S. minor (cf. Sars, 1902 [1903], Pl.37); there are, however, small differences in the structure of the various segments; the right 1st basal segment is short, stubby and partly fused with the left 1st basal segment; 2nd basal segment on the right side slightly swollen; right endopod short, triangular; 1st and 2nd exopodal segments of right side fused, slightly notched at the place of fusion; right 3rd exopodal segment elongate ovoid in outline, slightly curved and with some elevated ridges on the interior surface; left 1st and 2nd basal segments long and slender; left endopod cylindrical, elogate, cut off at the apex; left exopod 3-segmented, 1st segment cylindrical, 2nd almost cylindrical, slightly swollen near the apex and there with a small spiniform hair along the outer edge; 3rd exopodal segment of left side elongate, dagger-like, with swollen basal portion, tapering towards the end but not acutely pointed.

Sampling with a RMT1 net (mesh aperture: 315 µm), oblque tow from the surface to 200 m.
The survey area was located predominantly within the seasonal ice zone, and in the month prior to the survey there was considerable ice coverage over the western section but none over the east.

See map showing sampling sites in Calanus propinquus.

Horizontal distribution pattern of Scolecithricella minor (individuals per m2) in the winter North Sea.
Collected by WP2-net. Numbers (ind/m3) depth-integrated, extrapoled to the bottom (but at a maximum to a depth of 500 m) and expressed as ind per m2 of water surface.
Species Scolecithricella minor - Distribution map 7Issued from : A.C. Hardy & E.R. Gunther in Discovery Reports, 1935 (1936), 11. [p.166, Fig.76].
Charts showing the distribution of Scolecihricella minor in the upper layers of waters at stations in the 1926-7 surveys around South Georgia.
The squares represent the average numbers per 50 m vertical haul from 250 m (or less at shallow-water stations) to the surface with N 70 V nets.

For Vervoort (1957, p.102) the adult females as Scolecithricella glacialis) in the ‘Banzare’ collection show a considerable amount of variation in the development of P5. The P5 always consists of a pallet shaped gree segment, attached to a communal basal portion. This segment is 2.5-2 times as long as wide. The internal margin has a rather long spiniform seta, about as long as the sgment or slightly shorter, which is haired along its outer edge. The apex of the segment has a short spine, variable in length (1/2-1/8 the total length of the free segment) and always completely nude. At the external corner of the spine a small denticle is occasionally to be observed. The external margin of the segment is usually denticulated opposite the insertion of the internal seta ; in many specimens, however, such denticules appear to be absent. For Tanaka (1960, p.41) S. glacialis is only closely allied to S. minor.
For Park (1980, p.35) this species is the most common of the genus in Antarctic waters; It seemed to be the only species that inhabits mainly the epipelagic parts of the antarctic seas. For Mazzocchi & al. (1995) this form is similar to the occidentalis variety, distinguished mainly for the shape of the P5 in females
