Distribution of P. abdominalis in the Indian Ocean (upper water column of 200 m).
Triangle: South West Moonsoon season: April 16 to October 15 (white triangle = negative stations; black = animals collected). Circle: North East Moonsoon season: October 16 to April 15 (white circle = negative stations; black = numbers of ianimals collected).
Nota: Mainly distributed in the Equatorial region and along the southern half of the east coast of Africa, in the Agulhas current region. The presence of this form in the upper 200 m seems to be related with the SW Moonsoon season.

Abundance horizontal distribution of Pleuromamma abdominalis: non-random spatial structure.
Samples collected with a Longhurst-Hardy Plankton Recorder (LHPR) in the northern Sargasso Sea (34°10'N; 71°35'W) at three depth stata.

Nota: The pattern reveal that dominant variations occurred on scales of tens to hundreds of meters. The fluctuations in abundance are evident on different scales simultaneously.
After the authors, the abundance of species was not significantly nor consistently correlated to either temperature or alinity on the scales resolved by the tows, thus the LHPR data indicate that the physical environment or depth changes along the horizontal tows, was not, in general, a direct causative factor for the patterns observed.

Simple and partial correlation coefficients for the mean lengths of females and Chlorophyll a of the upper 100 m and surface temperatures averaged for the month preceding each mean lengthy measurement:
Number of pairs : 19
Simple correlations:
: XY = -0.758; XZ = 0.866; YZ = -0.927.
Partial correlations:
XY, Z constant = 0.238; XZ, Y constant = 0.667.
X: length; Y: temperature; Z: Clorophyll.
All values highly significant (P <0.01) except XY, Z constant.

Vertical distribution of calanoid copepod (mean +1 SE), abundance No/100 m3. 20- Pleuromamma abdominalis.
Night: shaded, day: unshaded.
Samples collected from 6 stations located off Cochin (India), SE Arabian Sea, November 1983, with a Multiple Closing Plankton Net (mesh aperture 300 µm), in vertical hauls at 4 depth intervalls (0-200, 200-400, 400-600, 600-1000 m).
Species Pleuromamma abdominalis - Distribution map 20Issued from : Y.-Q. Chen in CalCOFI Rep., 1986, XXVII. [Fig.11, p.219].
Vertical abundance of females, males and late copepodites.

Nota: The numbers of this species were the lowest for the genus Pleuromamma during the Krill Expedition in the Pacific east tropical (23°N to 3°S). Females were distributed at most of the stations except stations 16 and 17 (see chart, Fig.1).
Females usually occurred between 200 and 600 m, but at stations 18-20 they occurred at depths below 400 m in day samples.
The maximum concentration was 1000 individuals/1000 m3 and was found between 300 and 450 m (samples with a bongo net: mesh apertures 330 µm and 220 µm).T
The shallow depths of females and males in night samples suggest pronounced diel vertical migrations over an extensive vertical range. The ranges of vertical distribution of females and males were similar
The mean percentage combined was 1.8% (day: 0.6, night: 3.0) for all samples with the bongo net .

After Brinton & al., 1986 (p.246, Table 1); Wilson's (1950) Gulf of California records of P. robusta are probably based on misidentification of abdominalis.
For Fornshell & Ferrari (2010, p.763) the widespread distribution of morphs attribuable to forms typica and forma edentata, their co-occurrences, and the presence of specmens exhibiting morphologies incrementally graduated between the two forms, suggest that these two morphological forms of P. abdominalis are examples of a continuous variability within this species. Thus the authors do not believe that forma edentata should be treated as a subspecies of P. abdominalis. However it is important to continue to register the morphological variation among males of P. abdominalis. In situations where groups of females or males can be clearly categorized, they should be denoted simply as morphs.
After Lapernat & Razouls (2002, p.19) the Itoh's index value = 657.3 (number of teeth: 8) on the right Md, and 672.2 on the left Md (number of teeth: 8).
