Thoracopod VIII massive in relation to body size; protopod massive occupying almost two thirds of whole in ventral view, inner lobe dentate distally, hand-like; basipod with numerous spinules partially (yellow arrows in Fig. 6A, B); epipod absent; exopod with two distal setae and one medial seta, finger-like; endopod with two terminal setae, fused with basipod.</p><p>Remarks. Eobathynella gwangjuensis sp. nov. is morphologically most similar to E. yeojuensis in that: 1) the mandible has a seta-like tooth of the ventral edge, 2) the uropod sympod bears six setae, 3) the endopod of the uropod has a terminal spine and additionally smaller spines on the inner margin, 4) the exopod of male thoracopod VIII has two distal lobes, and the lower dentated lobe resembles a hand, and 5) the anal operculum protrudes. However, the new species differs from E. yeojuensis by the following features (characters of E. yeojuensis in parentheses): 1) the third segment of the antennule bears one lateral seta (two different size lateral setae), 2) the proximal segment of the maxilla bears one seta (two setae), 3) the endopod of thoracopod bears two claws (two claws and one seta) on the last segment, 4) the female thoracopod VIII displays two small round protrusions (round flattened protrusion), 5) the terminal spine on the endopod of uropod is unfused (fused) with the endopod and 6) the furcal ramus bears four (three) spines. The new species also shares characteristics with E. gracillima in female thoracopod VIII, forming a pair of small protrusions and having one seta on the proximal segment of the maxilla. However, the new species has four teeth instead of three on the mandibular incisor process and six spines instead of seven or eight spines on the uropod sympod.</p><p>Etymology. The species name is derived from Gwangju City, where the material was collected.</p></div>	https://treatment.plazi.org/id/03A687A56034FFC7B8E7D5FBFB1D0FF3	Public Domain	No known copyright restrictions apply.

Wonju-si (37°22′ 34.1″N, 127° 51′ 15.2″E), South Korea. Collected by Chi-Woo Lee (25 March 2015). Three female specimens examined (NNIBR 90880–90882). By our observation, no morphological differences were found between Eobathynella cf. yeojuensis specimens and E. yeojuensis . Thus, we consider that the studied specimens to correspond to E. yeojuensis . However, considering that subterranean taxa including the Parabathynellidae have many cryptic species that are difficult to distinguish based only on morphological characteristics and have been regarded as short-range endemics because of their small spatial distributions (Guzik et al. 2008; Perina et al. 2018), we cannot be completely certain that they are the same species until compared to molecular data from E. yeojuensis collected from the type locality.</p><p>Molecular analysis. We sequenced and analyzed DNA extracted from three E. gwangjuensis sp. nov. and one Eobathynella cf. yeojuensis specimen (Table 1). A total of 1,406 bp for 18S rDNA and 792 bp for CO1 were obtained. The intraspecific genetic distance between the three individuals of the new species ranged from 0.0 to 0.5% for CO1 and were all identical for 18S rDNA sequences. The pairwise genetic distance between the new species and Eobathynella cf. yeojuensis was 4% for 18S rDNA and 21.8–22.0% for CO1. We constructed a maximum likelihood tree for selected parabathynellid genera based on 417 bp of CO1 and 952 bp of 18S rRNA gene sequences (Fig. 7).</p></div>	https://treatment.plazi.org/id/03A687A5603EFFC6B8E7D5FBFF190F84	Public Domain	No known copyright restrictions apply.
