Cervical groove shallow, indistinct; H-shaped groove depressed and distinct (Fig. 2A). Epigastric cristae weak, postorbital cristae flat, indistinct. External orbital angle triangular, with about 5 small granules. Epibranchial tooth sharp, distinctly separated with external orbital angle by V-shaped gap. Anterolateral margin of carapace cristate, with about 12 granules (Fig. 2A). Maxilliped 3 exopod reaching nearly 1/3 of merus length, with long flagellum (Fig. 2C). Chelipeds (pereiopod 1) strongly unequal (Fig. 2A, B, D). G1 slender, subterminal segment about 1.1 times as long as terminal segment; 2 lobes of terminal segment strongly unequal, dorsal lobe longitudinally extended, oval shaped, ventral lobe sharp and short, reaching 3/7 of terminal segment (Figs 2E, 7C).</p><p>Ecology.</p><p>The species is usually inhabiting the clear hill streams at an altitude below 50 m. Stones could serve as shelter and leaf mould could serve as food (Dai, 1999).</p><p>Distribution.</p><p>China: Shenzhen of Guangdong Province (present record) and Hong Kong.</p><p>Remarks.</p><p>The specimens from Shenzhen, with gently convex dorsal surface of carapace, indistinct postorbital cristae, sharp epibranchial tooth, unequal lobes of the terminal segment of the G1 (Fig. 2), and other characteristics, agree well with the descriptions and illustrations in Ng and Dudgeon (1992) and Dai (1999). The ratio of the subterminal segment to the terminal segment of G1 calculated in this study is 1.1 (Fig. 7C), which is equal to that in Dai (1999) and slightly smaller than that in Ng and Dudgeon (1992) (1.17). Although the specimens are not from Hong Kong, they could still be determined as S. anacoluthon based on morphological examination and the proximity of their collection site to Hong Kong (Fig. 1).</p><p>Ng and Dudgeon (1992) listed the differences between Cryptopotamon and Sinolapotamon, including carapace, epigastric cristae, postorbital cristae, epibranchial tooth, and the ratio of the subterminal segment to the terminal segment of the G1. We, however, noticed that those differences are interspecific, while two or more species sharing the same character state with the remaining species is not. For instance, S. anacoluthon has a gently convex carapace similar to that of S. cirratum sp. nov. but different from the remaining congeners (Figs 2A, 3A). The weak epigastric cristae of S. anacoluthon are consistent with those of S. auriculatum and S. cirratum sp. nov. (Fig. 2A; see Zhu et al. 2010: figs 1a, 6a). The indistinct postorbital cristae of S. anacoluthon are comparable with those of S. auriculatum and S. palmatum (Fig. 2A; see Zhu et al. 2010: figs 1a, 6a). The sharp epibranchial tooth is consistent with that of S. auriculatum (Fig. 2A; see Zhu et al. 2010: fig. 1a). The different ratios of the subterminal segment to the terminal segment of the G1 could only be regarded as interspecific differences. Most importantly, all five species have accordant fundamental types of G1 (Fig. 7).</p></div>	https://treatment.plazi.org/id/67C45D865B9A5924A67F0302904ED4F6	Public Domain	No known copyright restrictions apply.

Tubercle of abdominal lock positioned at approaching mid-length of sternite 5. Sutures between sternites in female indistinct (Fig. 4C, D).

The dorsal lobe of the G1 terminal segment in S. cirratum sp. nov. is long and oval, which is similar to that of S. anacoluthon . The two species can nevertheless be distinguished by the ratio of the subterminal segment to the terminal segment of G1, which is 1.7 in S. cirratum sp. nov. and 1.1 in S. anacoluthon (Fig. 7A, C). When compared with S. patellifer, S. auriculatum and S. palmatum, the new species could be easily distinguished by the shape of the dorsal lobes and ventral lobes. The ventral lobe of S. cirratum sp. nov. is bluntly angular, while those of the other species in Sinolapotamon are pointed or shortly pointed (Fig. 7A, B, D, E). They also differ in comparative length of the ventral lobe relative to the terminal segment of the G1 (see Table 3). Additional differences among the known species of Sinolapotamon are provided in Table 3.</p><p>Etymology.</p><p>The new species is named Sinolapotamon cirratum sp. nov. because of the curled edges of the dorsal lobe of the G1. In the Latin, ‘cirratus’ means ‘curled’ .</p><p>Ecology.</p><p>The specimens were collected from puddles in the Duqiaoshan Forest Park. These crabs live in the shallow water or under the wet stones (Fig. 8A, B).</p><p>Distribution.</p><p>China: Guangxi Zhuang Autonomous Region: Rong County, Yulin City.</p></div>	https://treatment.plazi.org/id/6582241EC66250D6B9E686CAF90C8FA4	Public Domain	No known copyright restrictions apply.
