Species Paramisophria cluthae - Plate 1 of morphological figuresissued from : S. Ohtsuka in Publ. Seto Mar. Biol. Lab., 1985, 30 (4/6). [p.298, Table 2]. Comparison of three species within the genus Paramisophria.

Nota:
For Ohtsuka (1985, p.298) , as shown in Table 2, Tanaka's materials differ from P. cluthae described by Scott (1897) in some characteristics of Md and Mx1, as ponted out by Fosshagen( 1968)

Rem.: Fosshagen (1968a, p.62) scrutinizes some specimens from Raunefjorden and gives additional notes on the morphology: Most of the setae on A2 and mouthparts are considerably longer than shown in the drawings of Sars. The distal segment of the endopod of A2 bears 3 setae halfway along the inner edge. The denticulate process of Md is very similar to P. ammophila, having a short tooth on the inside of the base of the most prominent tooth and a row of small, stiff spinules on the outer edge of the process. The outer lobe of Mx1 is provided with 8 setae and the 1st inner lobe has 1 short spine in addition to the 5 strong spines (as found in P. ammophila); the endopod bears 2 small setae distally. On the left P5 of male, 1 seta is prsent on the distal outer margin of the 2nd segment.The form described by Tanaka (1966) with this name, collected NW of Kyushu, could be a different species (Lg. F: 1,59) [Cf. Paramisophria sp 2], however the differences between the females of P. cluthae and P. ammophila are so slight, it is difficult to judge whether Tanaka's record of P. cluthae from Japan is of P. cluthae, P. ammophila, or a third, new species. There are some small discrepancies in the structure of Mx1, P4 and P5 between Tanaka's figures and P. cluthae from Norway; it would be necessary to discover the male in japanese waters.
