Mx1 with praecoxal arthrite bearing 5 spines and one process; coxal endite unarmed, coxal epipodite with 8 plumose setae; endopod 1-segmented, bulbous, with 2 small setae of unequal lengths; exopod 1-segmented, fan-like, with 3 long setae terminally.
1st and 2nd praecoxal endites of Mx2 with 1 and 2 setae (1 seta missing in fig.2E) respectively; each coxal endite with 2 setae; basal endite with 1 naked stout spine; endopod 4-segmented, 1st to 4th segments with 1, 3, 2, 2 setae, respectively.
Syncoxa of Mxp with 1 medial and 2 subterminal setae and a patch of long spinules; basis fused with 1st endopodal segment (allobasis), ornamented with 2 patches of spinules and bearing 2 basal and 1 endopodal setae of unequal lengths, 2nd, 3rd and 6th endopod segments each with 4 setae, 4th and 5th with 3 setae.


Species Paramisophria reducta - Plate 3 of morphological figuresissued from : S. Ohtsuka, A. Fosshagen & T.M. Iliffe in Sarsia, 1993, 78. [p.61, Fig.3].
Female: A, P1 (anterior); B, P2 (anterior); C, P3 (anterior); D, P4 (anterior); E, inner distal corner of basis of right P4; F, P5 (anterior).


Species Paramisophria reducta - Plate 4 of morphological figuresissued from : S. Ohtsuka, A. Fosshagen & T.M. Iliffe in Sarsia, 1993, 78. [p.62, Fig.4].
Male: A, habitus (lateral right side); B, last prosomal somite (lateral right side); C, left A1 (position of geniculation indicated by arrow); D, P5 (anterior); E, 3rd exopodal segment of right P5.
Nota: Left A1 20-segmented, geniculation between segments 17 and 18; right A1 22-segmented (last two segments incompletely fused).

Distribution map of Paramisophria reducta by geographical zones
Loc:
NE Atlant.: Canary Is. (anchialine cave, Jameos del Agua, Lanzarote)
N: 2
Lg.:
(295) F: 1,71; M: 1,6; {F: 1,71; M: 1,60}
Rem.: After Ohtsuka & al. (1994, p.138) the fusion pattern of the antennulary segments is slightly different from the male of P. japonica in which segments WWI and XXII are incompletely fused whereas segments XXIII and XXIV are separate.
