Male: a, P5 (anterior); b, left P5 (endopod omitted), anterior; c, exopod of left P5 (anterior); d, right P5 (endopod omitted), posterior; e, distal end of exopod of right P5 (lateral); f, basipod of right P5 (anterior); g, idem (slightly tilted clockwise); h, idem (posterior); i, second exopodal segment of right P5 (anterior); j, idem (posterior).

4 - Laterally, genital operculum far short of reaching posterior end of somite (Fig.110-g).
5 - Laterally, right and left genital flanges symmetrical.
6 - Laterally, genital prominence distinctly separate from ventral wall of somite.
7 - Dorsally, as well as ventrally, lateral swellings of genital somite short of reaching posterior end of somite (Fig.110-a, e).
8 - Laterally, genital prominence reaching close to posterior end of somite (Fig.110-e). Posterior subterminal spine of 4th lobe of Mx2 (on 3rd segment) shorter than 1/2 length of saberlike spine (Fig.110-h).

2 - Basis of left P5 without a well-developed inner lobe (Fig.111-a).
3 - Basal inner lobe of right P5 armed with normal bristles (Fig.111-a, h).
4 - 3rd exopodal segment of right P5 with a short terminal lobe, less than 1/3 length of terminal spine (Fig.111- e).
