Carapace about 1.3 times broader than long, dorsal surface strongly convex longitudinally and transversely (Fig. 2A); cervical groove indistinct, H-shaped groove between gastric, cardiac regions distinct. Third maxilliped exopod without flagellum (Fig. 3B). Male pleon triangular, sixth somite width 2.2 times length; telson triangular, tip rounded, with proximal width 1.1–1.2 times length (Fig. 4B). G1 long, tip of terminal segment reaching suture between thoracic sternites 4, 5 in situ (Fig. 4A); subterminal segment 1.7 times as long as terminal segment (Fig. 3C; 5A); terminal segment slightly elongated inward (Fig. 3D; 5A), distal part of terminal segment elongated with ventrally directed semicircular lobe (Fig. 3D; 5A; 10A, B). Female vulvae partially exposed anteriorly to the thoracic sternites 5, 6 in situ, ovate, deep, posteromesial margin with a law raised rim, opened inward (Fig. 4D).</p><p>Type species. Semicirculara lincangensis sp. nov., by present designation.</p><p>Etymology. The genus name is derived from the Latin, semicircularis, which describes the G1 terminal segment, which has a ventrally directed semicircular lobe, as seen in the type species for the genus. Gender feminine.</p><p>Remarks. The new genus, Semicirculara, is morphologically most similar to Pararanguna Dai &amp; Chen, 1985, and Aparapotamon Dai &amp; Chen, 1985, as they share the following characters: the dorsal surface of the carapace is strongly convex longitudinally and transversely, the third maxilliped exopod is without a flagellum, the tip of the G1 terminal segment reaches beyond the sternal press-button in situ. But Semicirculara gen. nov. can be differentiated from Pararanguna by the G1 terminal segment being slightly elongated inward, and the distal part of terminal segment being elongated with a ventrally directed semicircular lobe (Fig. 3C, D; 5A) (versus G1 terminal segment ventral flap with semicircular protrusion, distal part of terminal segment elongated with a triangular lobe; Fig. 5B; cf. Dai, 1999: fig. 200 (4, 5)) (also Table 1); and by having the female vulvae ovate, opened inward, and posterointernally bordered by a low, nearly flat margin (Fig. 4D) (versus female vulvae subcircular, posterointernally bordered by a distinctly raised margin; Fig. 4F; cf. Dai, 1999: fig. 200 (8)) (also Table 1). Semicirculara gen. nov. can be differentiated from Aparapotamon by having the G1 subterminal segment about 1.7 times as long as terminal segment; terminal segment slightly elongated inward (Fig. 3C, D, 5A), distal part of terminal segment elongated with a ventrally directed semicircular lobe (Fig. 3D; 5A) (versus G1 subterminal segment about 1.3 times as long as terminal segment; distal part of terminal segment curved dorsally and inward, dorsal flap convex as discoid shape; Fig. 5C; cf. Dai, 1999: fig. 196 (4, 5)) (also Table 1); and by having the female vulvae seemingly placed between thoracic sternites 5 and 6 in situ, opening inward, and with the posteromesial margin having a low rim (Fig. 4D) (versus female vulvae fully on thoracic sternite 6, posterolaterally bordered by a distinctly raised margin; Fig. 4E; cf. Dai, 1999: fig. 195 (8)) (also Table 1).</p><p>1cf. Dai 1999: pl. 371; fig. 200. 2cf.

Female vulvae on thoracic sternite 6, ovate, opening upward, posterior margin arched distinctly (Fig. 8B, C).</p><p>Remarks. The new species fits well within the morphological definition of the hitherto monotypic Artopotamon Dai &amp; Chen, 1985 (type species: A. compressum Dai &amp; Chen, 1985): viz. the third maxilliped exopod is without a flagellum, the lateral margin of pleonal somite 6 is slightly convex (Fig. 6C, 9A), the G1 is generally slender, and female vulvae are on thoracic sternite 6, ovate, and with their posterior margin arched distinctly. Nonetheless, the new species can be distinguished from, Artopotamon compressum Dai &amp; Chen, 1985, by the shallow and indistinct cervical groove (Fig. 6A) (versus wide and distinct in A. compressum (Fig. 9D; cf. Dai, 1999: pl. 343); and the ventrolaterally curved G1, which reaches slightly beyond the sternal press-button, and with the subterminal segment about 1.4 times as long as terminal segment (Fig. 7A) (versus G1 straight, not reaching sternal press-button, subterminal segment about 2.3 times as long as terminal segment in A. compressum; Fig. 7C; cf. Dai, 1999: pl. 343: fig. 186 (3, 4, 5) (also Table 2). By examining the holotype of A. compressum, we found its G1 not reaching the sternal press-button (Fig. 9B), but it is not consistent with the diagnostic characters of Artopotamon as described by Dai &amp; Chen (1985), in which G1 merely reaches the sternal press-button. The most obvious specific character of the new species is that the distal part of the G1 terminal segment is distinctly wider than the proximal part (Fig. 7A), whereas the G1 terminal segment of A. compressum is stick-shaped and uniformly narrow throughout its length (Fig. 7C; cf. Dai, 1999: pl. 343: fig. 186 (3, 4, 5)) (also Table 2). In addition, the new species is found around the Jinsha River valley in Dali and Lijiang City, while A. compressum is recorded only in Pianma Town, Lushui County, Nujiang Lisu Autonomous Prefecture on the Nujiang River basin (Fig. 1). There are distinct geographical barriers between the two localities, such as the Lancang River, Gaoligong Mountains, which most likely contribute to the reproductive isolation of the two species.</p><p>Distribution and habitat. Artopotamon latopeos sp. nov. was found around the Jinsha River valley in Dali and Lijiang City. The crabs were found under rocks in mountain streams with an altitude range of 1800–2700 m.</p><p>Live coloration. Carapace is generally dark brown to purplish brown in life.</p><p>Etymology. The specific epithet, latopeos, is derived from an arbitrary combination of latus (Latin, broad) and peos (Greek, male intromittent organ or penis), in reference to the broader distal part of the G1 terminal segment. It is used here as a noun in apposition.</p></div>	https://treatment.plazi.org/id/232387B97F49F84DFF52FB461D7D56D6	Public Domain	No known copyright restrictions apply.
