            <p>Remarks.</p>
            <p> Allochthonius bainiensis sp. nov. is similar to  A. pandus sp. nov. and  A. xinqiaoensis sp. nov. in having the same number of setae on the carapace (14) and chelicera (6), while differs in the absence of a pair of curved chelal fingers (dorsal view) and the presence of lower number of teeth on chelal fingers (19 vs. 31-33 or 23 teeth on the fixed chelal finger and 17 vs. 26-28 or 23 teeth on the movable chelal finger). </p>
            <p> Allochthonius bainiensis sp. nov. differs from  A. brevitus and  A. yoshizawai Viana &amp; Ferreira, 2021 in the number of setae on the anterior of the carapace (4 vs. 6) and the cheliceral hand (5 vs. 6), and the number of rallum blades (9 vs. 11). </p>
            <p> Allochthonius bainiensis sp. nov. can be distinguished from  A. ishikawai Morikawa, 1954 and all  A. ishikawai subspecies by the number of setae on the carapace (14 vs. 16 or more), the presence of lower number of rallum blades (9 vs. 10) and larger body size (2.72 vs. 2.38 mm, which is the longest body length of all  A. ishikawai subspecies, for example, female of  A. ishikawai uyamadensis , Morikawa, 1954). </p>
            <p> Allochthonius bainiensis sp. nov. can be distinguished from the other species of  Allochthonius by the absence of any traces of eyes (Morikawa 1954, 1956, 1960; Hu and Zhang 2012; Viana and Ferreira 2021; WPC 2022). </p>
            <p>Distribution and habitat.</p>
            <p>This species is only known from the type locality, Liangfeng Cave (Figs 1B, 2), which is located near a road, 0.6 km southeast of Baini Village (Xishui County). This limestone cave has a medium-sized rectangular entrance (~ 3 m high and 5 m wide) with a large horizontally extending interior space. The interior of the cave is mainly divided into three tunnels, the left tunnel extends ~ 200 m, the middle tunnel extends ~ 500 m, and the right tunnel communicates with the middle tunnel, ~ 100 m in length. Human disturbance in the entrance zone is serious, but the deep zone remains pristine. The specimen was collected under a stone near the wall in the deepest part of the middle tunnel. This space is completely dark, with constant temperature and humidity (temperature ~ 9 °C, humidity ~ 90%).</p>

            <p> Allochthonius pandus sp. nov. can be distinguished from  A. ishikawai and all  A. ishikawai subspecies by the number of setae on the carapace (14 vs. 16 or more), the presence of lower number of rallum blades (9 vs. 10) and more teeth on both chelal fingers (26-28 vs. 11-17 teeth on the movable finger and 31-33 vs. 9-17 teeth on the fixed chelal finger). </p>
            <p> Allochthonius pandus sp. nov. can be distinguished from the other species of  Allochthonius by the absence of any traces of eyes (Morikawa 1954, 1956, 1960; Hu and Zhang 2012; Viana and Ferreira 2021; WPC 2022). </p>
            <p>Distribution and habitat.</p>
            <p>This species is only known from the type locality, Daozuo Cave (Figs 1C, 7), which is located near a road, 1 km southwest of Jinshan Village (Xishui County) and is surrounded by rural and agricultural fields. This limestone cave has a large, rectangular entrance (~ 1 m high and 30 m wide) and a total length of ~ 300 m, only a narrow tunnel leads to the deepest part of the cave, which is a slightly wider, low-temperature, high-humidity, and completely lightless environment (temperature ~ 11 °C, humidity&gt; 90%). All specimens were collected under stones in the deepest part of the cave.</p>

            <p>Remarks.</p>
            <p> Allochthonius xinqiaoensis sp. nov. is similar to  A. ishikawai shiragatakiensis Morikawa, 1954 in having a pair of distinctly curved chelal fingers, but differs by the presence of lower number of rallum blades (8 vs. 10), larger body size (body length 2.01 vs. 1.75 mm) and more chelal fingers teeth (23 vs. 9 on the fixed chelal finger and 23 vs. 11 on the movable chelal finger). </p>
            <p> Allochthonius xinqiaoensis sp. nov. can be distinguished from  A. pandus sp. nov. by the presence of more blades of coxal spines (6 vs. 4), lower number of rallum blades (8 vs. 9), thicker chela (chela 5.44 (♀)  × vs. 6.64-7.15 (♀)  × longer than broad), more setae on the coxae (3: 6: 7-9: 5: 5 vs. 3: 4: 5: 5: 5) and lower number of teeth on the chelal fingers (23 vs. 31-33 teeth on the fixed chelal finger and 23 vs. 26-28 teeth on the movable chelal finger);  Allochthonius xinqiaoensis sp. nov. can be distinguished from  A. bainiensis sp. nov. by the presence a pair of distinctly curved chelal fingers. </p>
            <p> Allochthonius xinqiaoensis sp. nov. differs from  A. brevitus and  A. yoshizawai in the number of setae on the anterior of the carapace (4 vs. 6) and the cheliceral hand (5 vs. 6), and the number of rallum blades (8 vs. 11). </p>
            <p> Allochthonius xinqiaoensis sp. nov. can be distinguished from  A. ishikawai and all the other  A. ishikawai subspecies by the number of setae on the carapace (14 vs. 16 or more), the presence of lower number of rallum blades (8 vs. 10) and more teeth on both chelal fingers (23 vs. 11-17 teeth on the movable chelal finger and 23 vs. 9-17 teeth on the fixed chelal finger). </p>
            <p> Allochthonius xinqiaoensis sp. nov. can be distinguished from the other species of  Allochthonius by the absence of any traces of eyes (Morikawa 1954, 1956, 1960; Hu and Zhang 2012; Viana and Ferreira 2021; WPC 2022). </p>
            <p>Distribution and habitat.</p>
            <p>This species is only known from the type locality, Sanjie Cave (Figs 1D, 13), which is located ~ 1.8 km northeast of Xinqiao Village (Fenggang County). This limestone cave has a small oval entrance (~ 1 m high and 2 m wide), ~ 200 meters in length, with a large, elongated exit at the end of the cave (~ 5 m high and 50 m wide). The interior entirety of the cave is large, inclined and extending downwards. The cave ground was covered with stones. The specimen was collected under a stone ~ 100 m from the cave entrance.</p>

            <p>Remarks.</p>
            <p> The new species shares similar characters with most species of  Centrochthonius Beier, 1931,  Spelaeochthonius and all species of "  Pseudotyrannochthonius " Beier, 1930 from the western US by the presence of only 16 setae on the carapace. Schwarze et al. (2021) emphasized the importance of the number of carapaceal setae in Holarctic pseudotyrannochthoniids, thus, it indicates that the three "  Pseudotyrannochthonius " species in the western US were misclassified in comparison with the twelve species from Australia and the three species from Chile (including the type species, the number of carapaceal setae is more than 18). It can be said that the genus  Pseudotyrannochthonius is endemic to the southern hemisphere (Harvey and Harms 2022). Thus, it is inappropriate to place this new species in  Pseudotyrannochthonius , even though the shape of this new species of coxal spines is similar to that of the three "  Pseudotyrannochthonius " species. </p>
            <p> The shape and number of the coxal spines are important distinguishing features between  Centrochthonius and  Spelaeochthonius (You et al. 2022). In our opinion, it is appropriate to place this new species to  Spelaeochthonius rather than  Centrochthonius , the reasons are as follows: for  Centrochthonius , the number of carapaceal setae is not fixed (e.g., occasionally 18 are present in  C. anatonus Harvey &amp; Harms, 2022) and only four or five coxal spines blades; for  Spelaeochthonius , the character of coxal spines is diverse (e.g., in  S. undecimclavatus Morikawa, 1956, which is club-shaped, not distally plumose). </p>
            <p> Spelaeochthonius wulibeiensis sp. nov. is similar to  S. cheonsooi You, Yoo, Harvey &amp; Harms, 2022, but differs by the number of setae on tergite I (2 vs. 4) and larger body size (body length 1.93 (♀) mm vs. 1.70 (♀) mm; chela 5.68 (♀)  × vs. 5.32 (♀)  × longer than board, length 1.76 (♀) mm vs. 1.49 (♀) mm). </p>
            <p> Spelaeochthonius wulibeiensis sp. nov. can be distinguished from  S. seungsookae You, Yoo, Harvey &amp; Harms, 2022 by the number of setae on tergite I (2 vs. 4) and smaller body size (body length 1.93 (♀) mm vs. 2.05-2.36 (♀) mm; chela length 1.68-1.74 (♂), 1.76 (♀) mm vs. 1.90 (♂), 1.92 (♀) mm); from  S. undecimclavatus and  S. dorogawaensis by the number of setae on chelicera (6 vs. 7), a slender palp (palpal femur 7.24 (♂)  × vs. 4.80-5.40 (♂)  × longer than board; chela 6.21-6.22 (♂)  × vs. 5.50-6.13 (♂)  × longer than board) and lower number of blades of coxal spines (7-8 vs. 10-11); from  S. akiyoshiensis Morikawa, 1956 and  S. kobayashii Morikawa, 1956 by the number of setae on chelicera (6 vs. 7), lower number of movable chelal finger teeth (16-19 teeth vs. min. 26 teeth) and a slender palp (palpal femur 7.24 (♂)  × vs. 5.00-5.60 (♂)  × longer than board; chela 6.21-6.22 (♂)  × vs. 5.13-5.74 (♂)  × longer than board); from  S. dentifer (Morikawa, 1970) by the number of setae on chelicera (6 vs. 7), lower number of movable chelal finger teeth (16-19 teeth vs. min. 36 teeth) and a shorter chela (chela 6.21-6.22 (♂), 5.68 (♀)  × vs. 6.85 (♂), 7.12 (♀)  × longer than board, length 1.68-1.74 (♂), 1.76 (♀) mm vs. 1.85 (♂♀) mm); from  S. kubotai by the slightly smaller body size (body length 1.93 (♀) mm vs. 2.03 (♀) mm; chela 5.68 (♀)  × vs. 5.70 (♀)  × longer than board; movable chelal finger 1.68 (♀)  × vs. 1.87 (♀)  × longer than) and the number of setae of coxal spines (7 or 8 vs. 11); from  S. kishidai (Morikawa, 1960) by a slender palp (palpal femur 7.24  × vs. 4.90  × longer than board; movable chelal finger 0.61-0.63  × vs. 0.67-0.69  × longer than board) (Morikawa 1954, 1956, 1960, 1970; You et al. 2022). </p>
            <p>Distribution and habitat.</p>
            <p>This species is known only from the type locality, Wulibei Cave (Figs 1A, 18A-C), which is located ~ 1.2 km east of Yangguan Village (Weining County). This limestone cave has an elongated entrance (~ 2.5 m high and 8 m wide) with some corn stalks scattered nearby. Entrance of the cave has a large muddy cave hall, connected to a small hall through a narrow tunnel, which is a more enclosed, completely dark space, covered with gravel, with temperatures ~ 10 °C and humidity ~ 90%. The specimen was collected under a stone in a small cave hall.</p>
