Carapace broader than long, ovate; dorsal surface convex, smooth, regions not clear; branchial regions swollen, smooth (Figs 2A, 4A). Epigastric cristae weakly developed, oblique, separated from each other by deep inverted Y-shaped groove; postorbital cristae low, indistinct, confluent with epigastric cristae (Figs 2A, 4A). External orbital angle bluntly triangular, outer margin and anterolateral margin of carapace confluent (Figs 2A, 4A). Anterolateral margin of carapace entire convex, smooth; posterolateral margins of carapace gently converging, smooth (Figs 2A, 4A). Epibranchial tooth indistinct (Figs 2A, 4A). Sub-orbital, sub-hepatic and pterygostomial regions smooth (Figs 2B, C, 4B, C). Antennular fossae slit-like in anterior view; median lobe of epistome posterior margin narrowly triangular (Figs 2B, 4B). Exopod of third maxilliped reaching beyond anterolateral corner of ischium, without flagellum (Fig. 3G). Thoracic sternites 3/4 in male completely fused (Figs 2C, 3C, E, 4C). Vulvae transversely ovate, widely located from each other, touching suture of sternites 5/6 (Fig. 3F). Male pleon broadly triangular (Figs 2C, 3C, 4C). G1 slender, reaching pleonal locking tubercle in situ (Figs 3E, H, I, 4D, E); subterminal segment stout, slightly sinuous (Figs 3H, I, 4D, E); terminal segment slender, relatively long, subconical, strongly sinuous, bent inwards, inner margin strongly concave, ~ 0.6 × length of subterminal segment, without groove for G2 on ventral side, tip rounded, dorsal flap absent (Figs 3H, I, 4D-G). G2 longer than G1; terminal segment relatively long; subterminal segment ~ 1.5 × length of terminal segment (Fig. 3J).</p><p>Remarks.</p><p>Parvuspotamon was previously known by two species, P. yuxiense (type species) and P. dixuense . The latter species was recently described by Naruse et al. (2018) based on the characters in the carapace and G1 terminal segment. Based on morphological and molecular data, P. dixuense, however, is transferred to Songpotamon gen. nov. since it possesses the generic characters of the new genus (see Remarks for the new genus). The present revision thus restricts Parvuspotamon only to the type species, i.e., P. yuxiense .</p><p>The morphological similarities between Parvuspotamon and Songpotamon gen. nov. notwithstanding, Parvuspotamon can easily be distinguished from Songpotamon gen. nov. by the characters in the carapace, vulvae and G1 (see Remarks for Songpotamon gen. nov.). Parvuspotamon is immediately distinguished from most of the remaining Chinese potamid genera by the combination of its medium body size (adult carapace width 16-26 mm), the strongly sinuous G1 terminal segment, and the absence of a flagellum on the exopod of the third maxilliped (Dai and Bo 1994; Dai 1999).</p><p>Geographic distribution.</p><p>Parvuspotamon is known only from Yunnan Province of southwest China.</p></div>	https://treatment.plazi.org/id/9644668323285EB892B2CB81DD77C366	Public Domain	No known copyright restrictions apply.

Songpotamon malipoense gen. et sp. nov., however, can immediately be distinguished from S. dixuense comb. nov. by the following characters: 1) carapace dorsal surface glabrous, with dense pits (Fig. 7A) (vs with few short setae and scattered pits); 2) inverted Y-shaped groove between the epigastric cristae relatively deep (Fig. 7A) (vs relatively shallow); 3) chela generally smooth on the outer surface (Fig. 8A) (vs relatively rugose); 4) pterygostomial regions with prominent rounded granules (Fig. 7B) (vs relatively smooth); 5) antennular fossae rectangular in anterior view (Fig. 7B) (vs slit-like); 6) median tooth on the epistome posterior margin broadly triangular (Fig. 7B) (vs narrowly triangular); 7) male pleonal somite 6 relatively narrower (vs relatively broader); and 8) G1 with an almost straight inner margin of the subterminal segment (Fig. 9D, E, 10C, D) (vs with a gently concave inner margin) (cf. Naruse et al. 2018: figs 24A, B, 25B, 26A, C). Biogeographically, these two species are also isolated due to their occurrence in different drainages, with the new species in the Yuanjiang-Red River Basin and S. dixuense comb. nov. in the Pearl River Basin (Fig. 1). Songpotamon malipoense gen. et sp. nov. need not be confused with S. funingense gen. et sp. nov. (see Remarks for the latter new species).</p><p>Geographic distribution.</p><p>Songpotamon malipoense gen. et sp. nov. is known from Malipo County, southern Wenshan Prefecture, Yunnan Province, southwest China.</p></div>	https://treatment.plazi.org/id/040D14175DB35B3C8581837161CDF30D	Public Domain	No known copyright restrictions apply.

G2 longer than G1; terminal segment relatively short; subterminal segment ~ 5 × length of terminal segment (Fig. 9C, F).</p><p>Etymology.</p><p>The genus is named after the late Prof. Daxiang Song, a senior academician in the Chinese Academy of Sciences, in the honour of his immense contributions to Chinese invertebrate systematics; in arbitrary combination with the genus name Potamon Savigny, 1816. Gender of genus neuter.</p><p>Remarks.</p><p>Songpotamon gen. nov. is established for S. dixuense comb. nov. and two new species, S. funingense sp. nov. and S. malipoense sp. nov. Songpotamon dixuense comb. nov. was previously in Parvuspotamon, but here transferred to Songpotamon gen. nov. because it possesses the key generic characters of the new genus, which includes, the medium body size (adult carapace width 19-27 mm), the third maxilliped exopod lacking a flagellum, the external orbital angle being bluntly triangular, the slender G1 shape, and the terminal segment being subconical and with a groove for G2 on the ventral side (cf. Naruse et al. 2018: figs 24-27).</p><p>Songpotamon gen. nov. can easily be distinguished from Parvuspotamon by the following characters: 1) carapace dorsal surface with scattered pits (Figs 5A, 7A; cf. Naruse et al. 2018: fig. 25A) (vs smooth; Figs 2A, 4A); 2) outer margin of the external orbital angle separated from the anterolateral margin of the carapace by the shallow cleft (Figs 5A, 7A; cf. Naruse et al. 2018: fig. 25A) (vs confluent with each other; Figs 2A, 4A); 3) vulvae relatively close located to each other (Figs 6H, 8H; cf. Naruse et al. 2018: fig. 27) (vs relatively widely located from each other; Fig. 3F); 4) G1 terminal segment relatively shorter, ~ 0.4 × the length of the subterminal segment, with a truncated tip (Figs 9A, B, D, E, 10A-D; cf. Naruse et al. 2018: fig. 26A-D) (vs relatively longer, ~ 0.6 × the length of the subterminal segment, with a rounded tip; Figs 3H, I, 4D-G); 5) G1 terminal segment bent outwards but with the tip gently recurved upwards, the inner margin being straight to gently curved (Figs 9A, B, D, E, 10A-D; cf. Naruse et al. 2018: fig. 26 A-D) (vs bent inwards, with the inner margin being strongly concave; Figs 3H, I, 4D-G); and 6) groove for G2 on the G1 terminal segment clearly visible in the ventral view (Figs 9 B, E, 10B, D; cf. Naruse et al. 2018: fig. 26A, B) (vs not visible; Figs 3I, 4E, G).</p><p>Furthermore, Songpotamon gen. nov. is most likely to be confused with Chinapotamon Dai &amp; Naiyanetr, 1994, as both the genera have a very similar carapace physiognomy, and their G1 terminal segment is subconical, with the groove for G2 visible in the ventral view. The new genus, Songpotamon gen. nov., is nevertheless distinguished from Chinapotamon by the following characters: 1) carapace relatively high (Figs 5B, 7B) (vs relatively low); 2) ambulatory legs relatively stout (Figs 5A, C, 6D, 7A, C, 8D) (vs relatively slender); 3) anterolateral margin of the carapace being less convex (Figs 5A, 7A) (vs strongly convex); 4) third maxilliped exopod without flagellum (Figs 6C, 8C) (vs with well-developed flagellum); 5) thoracic sternites 3/4 with incomplete but distinct groove demarcating suture (Figs 5C, 6E, G, 7C, 8E, G) (vs groove demarcating suture absent); and 6) G1 terminal segment gently curved outwards (Figs 9A, B, D, E, 10A-D) (vs strongly bent outwards) (cf. Dai 1999: figs 42-47; Ng 2017: figs 2-4, 6-8; Zou et al. 2018: figs 2-6).</p><p>Geographic distribution.</p><p>Songpotamon gen. nov. is known from Wenshan Prefecture, eastern Yunnan Province, southwest China.</p></div>	https://treatment.plazi.org/id/A7EDE5125B5155E0B5247DE472780CA5	Public Domain	No known copyright restrictions apply.
