Coxa narrow.</p><p>Mx (Figure 2C): palp two-segmented; first segment bearing four setae of which three in outer position and one more central; second segment with two robust, long setae and four shorter, thinner setae.</p><p>T1: damaged in the available specimens.</p><p>T2 (Figure 3A): five-segmented; basis (not shown) perhaps lacking d1 seta; second segment with antero-distal seta e; third and fourth segments weakly subdivided, with f and g seta respectively; last segment with h1 seta slightly shorter than bearing segment, stout apical h2 claw about six times longer than terminal segment and tiny h3 seta in subapical, posterior position.</p><p>T3 (Figure 3B): protopodite with short d1 seta and long dp seta, the latter exceeding distal end of next segment; endopodite with three segments; first endopodal segment without setae, second segment with subapical g seta; third segment with three setae: h1 short, h2 strong and h3 long and thin, with length ratio approximately 1:2.7:3.1.</p><p>CR (Figure 3C): rami stout, with long seta sp and strongly reduced seta sa; terminal claws robust and serrated, Ga length approx. 1.2 times Gp and 0.9 times the ramus length.</p><p>CR attachment (Figure 3D): straight, branched at both ends.</p><p>Eye pigment absent.</p><p>Description of male. Male unknown.</p><p>Accompanying ostracods. One specimen of Cypria ophtalmica (Jurine, 1820) and an unidentified ostracod larval stage collected on 4 July 2018.</p><p>Remarks</p><p>Schellencandona antoniae sp. nov. is formally described here, despite only a few female specimens being available. We have chosen to proceed with the description as both valve and soft-part characteristics are provided, enabling us to clearly distinguish the new species from its congeners, even in the absence of important diagnostic features of the male which, although not found, is presumed to exist (see Discussion). Furthermore, repeated samplings at the type locality to collect additional specimens to be studied were unsuccessful.</p></div>	https://treatment.plazi.org/id/03888731FFB9FFDAE288FDBAFB506F8D	Public Domain	No known copyright restrictions apply.

The specimen’s left valve was severely damaged prior to dissection, making it unsuitable for the taxonomic description. RV (Figures 1H–J) with straight dorsal margin slightly tapering towards posterior end. Evenly rounded anterior margin distinctly broader than posterior one, the latter gently tapering towards ventral corner. Surface covered by reticulate pattern organized in polygonal meshes, with weakly calcified muri and smooth fossae. The specimen shows notable similarity to Schellencandona insueta (Klie 1938) (see Figure 11, page 13 in Klie 1938a). The valves are also very similar in size (L= 0.47 mm and 0.46 mm, H/L 0.51 and 0.52 in the specimen studied here and in S. insueta, respectively). In Klie (1938a, 1938b), the valves of S. insueta are described as smooth and hairy, but no mention is made of a reticulate pattern, which is instead evident in the specimen from the Po River also when observed in transmitted light.</p><p>Regarding the soft parts of the female of S. insueta, Klie (1938a) only published drawings of the cleaning leg and the furcal ramus. In the specimen examined here, the ratio between seta h1 and seta g of the cleaning leg is approximately 2:1 (Figure 4A), whereas in S. insueta the two setae are of similar lengths (Klie 1938a; Figure 15, page 14). Particularly interesting is the presence in the Po River specimen of two denticles and two rows of setulae on each of the two terminal claws of the furcal ramus (Figure 4B), similar to what is illustrated by Klie (1938a; Figure 16, page 14) for S. insueta . Notably, this feature is not detectable in any other known species of the genus Schellencandona .</p><p>The studied specimen contained bundles of sperm inside the carapace, indicating the presence of males at the sampling site.</p><p>Since only one specimen from the Po River was available and its preservation was insufficient, along with the lack of highly diagnostic male sexual characteristics, it seems advisable to refrain from fully confirming its specific status at this stage, despite the observed similarities to S. insueta . A more definitive verification will require the potential acquisition of additional material .</p></div>	https://treatment.plazi.org/id/03888731FFB5FFDDE288FDBBFD996C19	Public Domain	No known copyright restrictions apply.
