Carapace Subquadrate, flat, dorSal Surface Smooth (Fig. 1 A); third maXilliped iSchium about 1.4 timeS aS long aS broad, eXopod without flagellum (Fig. 1 B, 2B); male abdomen broadly triangular, telSon broadly triangular, with about 1.6 timeS aS broad aS long (Fig. 1 C, 3B); median grooVe of male thoracic Sternum deep, interruption between SutureS of SterniteS 4/5, 5/6, 6/7 broad (Fig. 3 A); G1 long, diStal part of Subterminal Segment and terminal Segment arch Shaped (meSioVentral View; Fig. 2 E), tip of terminal Segment reaching Suture between thoracic SterniteS 4/ 5 in situ (Fig. 3 A); Subterminal Segment about 1.9 timeS aS long aS terminal Segment; terminal Segment tongue-Shaped, diStinctly curVed VentralwardS (Ventral View) (Fig. 2 D, E, F and G).

Arquatopotamon jizushanense sp. n., by monotypy.</p><p>Etymology. The genuS name iS deriVed from the Latin arquatus for “arched”, which deScribeS the arched male firSt gonopod of the type SpecieS for the genuS. Potamon iS the type genuS of the family Potamidae . Gender neuter.</p><p>Remarks. Although thiS new genuS, Arquatopotamon, iS Similar to Tenuipotamon, Pararanguna, Trichopotamon, Potamiscus, and Aparapotamon by haVing a third maXilliped eXopod without a flagellum, it can be eaSily diStinguiShed from the fiVe related genera by a G1 with an arch-Shaped diStal part of the Subterminal Segment and terminal Segment, the female gonoporeS located on thoracic SterniteS 5/6, and a combination of characterS including the carapace and male telSon (Table 2; Fig. 4; See Dai 1999: pl. 382, fig. 206; Dai 1999: pl. 371, fig. 200; Dai 1999: pl. 366, fig. 198; Dai 1999: pl. 192, fig. 102; Dai 1999: pl. 349, fig. 187). Although the female Sternal gonoporeS (VulVae) in eubrachyuranS are uSually located on Sternite 6 (DaVie et al., 2015; Guinot et al., 2013), they are partially eXpoSed anteriorly to the SterniteS 5/ 6 in the potamiScine genuS Pararanguna (Dai and Chen, 1986; Dai, 1999) and eVen to the Suture between thoracic SterniteS 4/ 5 in the new genuS. OtherwiSe, the detailS in the female genital duct of the new genuS could not be clearly detected under the microScope. Further Study iS needed for underStanding the three-dimenSional (3D) Structure of the female genital duct, which correSpondS to the Specialized tip of the G1, by uSing LED-Structured illumination microScopy (LED-SIM) (Ruan et al., 2016; Bai et al., 2017).</p><p>1.
