Taxonomy of Cypricercus View in CoL
Cypricercus View in CoL presently comprises 22 nominal species. These were reexamined here based on (type) materials and on literature descriptions and nine species were retained in Cypricercus View in CoL s.s. ( Table 2). All other species belong to other genera or have an unknown status. Cypricercus mongolicus Daday (1909) is here transferred to the genus Eucypris View in CoL ( Table 3), relying mainly on the morphology of caudal ramus and hemipenis.
Cypricercus salinus De Deckker, 1981 View in CoL was described from a saline lake (salinity range 0.34-12.3 ppt) in Victoria, Australia. The Triebel’s loop of C. salinus View in CoL is equivocally presented in the illustration, maybe because it was not well developed. Indeed, De Deckker (1981) reported that an almost closed eyelet was encountered on dorsal branch. To clarify this enigmatic character, the type material should be reexamined. Based on the position of the Triebel’s loop in dorsal branch, we here allocate C. salinus View in CoL to Bradleystrandesia View in CoL ( Table 3). In addition, this species also shares some other characters of genus Bradleystrandesia View in CoL . Firstly, the distal seta of the caudal ramus is short (considerably shorter than half of the proximal claw). Secondly, the proximal seta is short (somewhat less than the end of the ramus) and its position is comparatively lower than the proximal claw. Thirdly, whereas the insertions of proximal and distal claws in Bradleystrandesia View in CoL are slightly apart from each other, in other Cypricercinae View in CoL these insertions are relatively close to each other.

De Deckker (1981) also described Cypricercus unicornis View in CoL from Newmann’s Rocks in West Australia. His drawing and description illustrated that there is a Triebel’s loop in the dorsal branch. However, this Triebel’s loop seems to be incorrect in shape and position. It is therefore possible that the attachment of the caudal ramus was broken during dissection, resulting in a translocation of Triebel’s loop from main branch to dorsal branch. Additionally, we found that the shape of the caudal ramus and the valve morphology in this species are more conform to Cypricercus View in CoL than to Bradleystrandesia View in CoL . We thus maintain this species in Cypricercus View in CoL .
We here redescribe Cypricercus inermis ( Brady, 1904) and found that the characters of this species, e.g. the divided α-seta on Md-palp, the absence of the channel in the fused zone of LV, elongated carapace and the morphology of Zenker’s organ, are congruent to those of Cypricercus . Martens (2001) considered Cypricercus inermis , previously in Tanycypris , to be a synonym of Cypricercus cuneatus . The present study reveals that C. inermis is not identical to C. cuneatus and differs by the following characters: (1) the lateral shield of the hemipenis in C. inermis is elongated, subtriangular and its distal end is beak-like; in C. cuneatus this shield is subquadrate with bluntly pointed distal end; (2) the Zenker’s organ of C. inermis is slightly longer (length c. 3.5 times the width) and set with approx. 22 spiny whorls, whereas in C. cuneatus this organ is shorter (length c. 3 times the width) and is composed of 20 spiny whorls; (3) the chaetotaxy of the soft parts is also different between both species, for example, in the length of the dorsal subapical seta on the first segment of the A1, the size and shape of the Rome organ, the ventral apical seta on the fifth A1-segment and the morphology of caudal ramus and attachment: in C. inermis the ventral margin of the caudal ramus is composed of 4 groups of fine spines and the ventral branch of the attachment is stout and short, while in C. cuneatus the ventral margin of the caudal ramus is continuously finely serrated and the ventral branch of the attachment is slim and somewhat longer; (4) the carapace of C. inermis is narrower in lateral view, and C. inermis has the posterior margin of the RV slightly more produced than that of C. cuneatus , resulting in a relatively unequal posterior end, as can be clearly seen in dorsal view; (5) the number of inner lists along the anterior part of the LV is different between C. inermis and C. cuneatus , 1 inner list in the former, 2 inner lists in the latter. Therefore, C. inermis is here reinstated as a valid species.
