Genus Monchenkocyclops gen. nov.

Diagnosis. Body slender, cyclopiform. Integument weakly sclerotized, smooth, without cuticular pits or cuticular windows, with numerous sensilla and pores. Female genital double-somite large swollen antero-ventrally, widest at first third, with larger anterior part of seminal receptacle and small posterior part; copulatory pore situated at about midlength; ovipores situated dorsolaterally at 2/5 of double-somite length. Anal somite with short medial cleft, and with small and short anal operculum small, not reaching posterior margin of anal somite. Caudal rami cylindrical, parallel, inserted close to each other, from 2.5 to 3.2 times as long as wide and twice as long as anal somite; principal terminal setae with breaking planes, dorsal seta from almost as long as ramus to half as long, outermost terminal seta about 0.7 times as long as ramus, innermost terminal seta shorter or longer than outermost terminal one. Female antennula 11-segmented or 12-segmented, with armature formula 8.4.8 (2.6).4.2.2.3.2+ae. 2.3.7+ae. Male antennula strongly prehensile and digeniculate, 17-segmented, with armature formula 8+3ae.4.2.2 +ae.2.2.2.2.2+ae.2.2.2.2+ae.2.1+ae.4.8+ae. Antenna five-segmented, without exopod, with armature 2.1.9(8). 7. Labrum with two short rows of slender spinules on anterior surface, and ten to 12 sharp teeth between produced and sharply and inwardly pointed lateral corners on cutting edge. Mandibula cutting edge with several slen- der spinules on anterior surface, eight apical teeth, and dorsalmost bipinnate seta; palp with two long and plumose and one short and smooth setae. Maxillula with four distal spines and six medial elements; palp two-segment- ed, armed with seven setae. Maxilla five-segmented, with armature formula 2.3.2.2.3. Maxilliped four-segmented, with armature formula 2(3).2.1.3. All swimming legs with three-segmented exopods and two-segmented endopods; first and second exopodal segments of all legs with inner seta and outer spine; first endopodal segment of all legs with inner seta; third exopodal segment spine formula 2.3.3.3 and setal formula 4.4.4.4; second endopodal segment spine formula 1.1.1.2 and setal formula 5.5.6.5 (4); inner apical spine on second endopodal segment of fourth leg longer than outer apical spine; coxae of all legs with inner seta; bases of all legs with outer seta, basis of first leg additionally armed with stout inner spine. Fifth leg inserted ventro-laterally, small, two-segmented; first segment half as long as greatest width, with single outer slender seta; second segment longer than first and about 1.5 times as long as wide, with apical long seta and subapical inner spine; subapical spine shorter than second segment. Female sixth leg small cuticular plate covering ovipore, with two short and smooth spines and outermost longer and pinnate seta. Male sixth leg larger cuticular plate, with inner spine and two setae on outer distal corner; outermost seta more than twice as long as inner seta and more than three times as long as innermost spine.

Type species. Monchenkocyclops changi sp. nov.
