Rostrum (Fig. 11 A) fused with cphth, strongly constricted, slightly longer than broad, and cleft at its tip, with 2 sensilla; tube pore not recognisable in any of the four males.</p><p>A 1 (Fig. 11 B) consisting of 6 segments, chirocer, geniculation between fifth and sixth segments. The first two segments longest, the third and sixth segments slightly shorter than the fifth one, which is slightly swollen; acrothek not discernible; the fourth segment minute, unarmoured. Setal formula: I – 1; II – 7; III – 4; IV – 0; V – 9 + aes; VI – 9 + aes.</p><p>P 3 exopod as in female. Endopod 3 - segmented (Fig. 7 B), enp 1 tiny and bare, enp 2 more than three times longer than enp 1, ending on inner apical edge in cuspidal apophysis that slightly overtops the apical margin of enp 3. The latter is as long as enp 1 and bears 2 apical bare setae, the outer one being approximately seven times longer than the inner one.</p><p>P 4 exopod as in female. Endopod 2 - segmented (Fig. 8 B), enp 1 small, nearly squarish, and bare. Enp 2 about 3.4 times longer than enp 1, apically with 2 setae, the inner one bare, the outer one approximately 3.4 times longer than the inner seta and biplumose. Subapically on the outer margin arises 1 bipinnate spine.</p><p>P 5 (Fig. 9 C) generally as in female but smaller. Basoendopod more compact than that of female, without spinulose row; endopodal area with 2 bare setae and small tube pore. Exopod only slightly longer than basoendopod, without spinulose ornamentation, setation as in female, likewise with 1 tube pore.</p></div>	https://treatment.plazi.org/id/D6AB22D2EA4653668E42E8856E054A5E	Public Domain	No known copyright restrictions apply.
