Two new troglomorphic pseudoscorpion species, Bisetocreagris maomaotou sp. nov. (Family Neobisiidae) and Tyrannochthonius chixingi sp. nov. (Family Chthoniidae) are described from one cave in the tower karst of northern Guangxi Province, China. This cave is located at close proximity to a village and an adjacent urban area. As with many caves in th...

The pseudoscorpion genus Haplochernes Beier, 1932, is redescribed and restricted to those species of Chernetidae with only four setae on the cheliceral hand and a pair of moderately long, slender spermathecae. This new definition is shared by only two species: the type species H. boncicus (Karsch, 1881) from Japan and possibly Taiwan and H. wuzhien...

Detailed diagnosis, descriptions, and illustrations are presented.

... Interestingly, no species of Spelaeochthonius have yet been recorded from China despite the abundance of karst habitats in this country and the ongoing discovery of troglomorphic pseudoscorpions in several provinces (Gao et al. 2018(Gao et al. , 2020Feng et al. 2019Feng et al. , 2020. Recent studies indicate that Allochthonius is diverse in forest habitats throughout China, with nine species already described (Gao et al. 2016) but, again, no subterranean species has been collected there to date and all troglobiontic species belong to the Chthoniidae (genera Lagynochthonius Beier, 1951 andTyrannochthonius Chamberlin, 1929) and the Neobisiidae (Bisetocreagris Ć určić, 1983 andParobisium Chamberlin, 1930) (Feng et al. 2020) that have no known troglobiontic species in Korean caves. ...
... To date, 33 cave-dwelling pseudoscorpion species, representing three families (Chthoniidae, Neobisiidae, Chernetidae), have been described from China. Among them, eight species are known from Yunnan (Schawaller 1995;Mahnert 2003Mahnert , 2009Mahnert and Li 2016;Gao et al. 2017;Li et al. 2017;Gao et al. 2018;Li et al. 2019;Feng et al. 2020;Gao et al. 2020;Zhang et al. 2020). ...
... Although most species of Rhopalochernes have five or six setae on the cheliceral hand, Heurtault (1998) included two new species of Rhopalochernes from Panama and Venezuela which possessed only four setae. This unusual characteristic is shared by very few other Chernetidae, including some species of Americhernes Muchmore, 1976, Anaperochernes Beier, 1964, Haplochernes Beier, 1932, Meiochernes Beier, 1957and Neoallochernes Hoff, 1947(Gao et al. 2017Harvey & Mahnert 2019). Recently, we found several chernetid specimens in the Caribbean coast of Colombia which share all of the traits characteristic of Rhopalochernes. ...

... The coxal blade morphology in Centrochthonius was reported by Redikorzev (1918, fig. 9C) who illustrated five short and acute coxal blades for the type species C. kozlovi and this configuration has since been found in the recently discovered C. cheni from high altitude habitat in central Asia (Gao et al. 2016), and a fossil species C. bitterfeldicus Schwarze et al., 2022 from Bitterfeld amber in Germany (Schwarze et al. 2022). It should be noted here that C. cheni had initially been described in Pseudotyrannochthonius following the generic arrangements proposed by Muchmore (1967) who had synonymised Spelaeochthonius with Pseudotyrannochthonius and also placed all pseudotyrannochthoniid species from the western U.S.A. in this genus, which was originally described from Chile (Beier 1930). ...
... The two extra setae appear to be abnormalities and the authors have observed a duplication of these posterior setae in large series of other species such as Pseudotyrannochthonius giganteus (Beier, 1971) from Western Australia, the only species in this family that has been studied extensively both for morphology and genetic structure (Harms 2018;Harms et al. 2019;Michalski et al. 2022). Note that in Allochthonius, the most common East Asian pseudotyrannochthoniid genus, the posterior row frequently comprises four carapaceal setae, although the cave or soil-adapted species in this genus usually have only two setae, and all setae are usually arranged in a pattern 8-10: 4-6: 4-6: 2 (rarely 4): 4 (¼ 22-28) (¼ 22-28) (e.g., Morikawa 1956Morikawa , 1970Chamberlin 1962;Lee 1982;Sato 1984;Schawaller 1995;Sakayori 1999Sakayori , 2002Sakayori , 2014aHu & Zhang 2011, 2012Gao & Zhang 2013;Zhang & Zhang 2014;Gao et al. 2016). Four species of Allochthonius have fewer than 22 setae: A. brevitus has 6: 4: 2: 2: 2 (¼ 16) (Hu & Zhang 2012); A. yoshizawai has 6: 6: 2: 2: 2 (¼18) (Viana & Ferreira 2021); A. montanus has 6: 4: 2: 2: 4 (¼18) (Sakayori 2000) and three of the four subspecies of A. ishikawai have a total of 18 or 20 setae including eight setae in the anterior row and two setae in the posterior row but without any details regarding the number of setae in the other rows (Morikawa 1954 Remarks.-The ...
... The species belonging to this genus are generally identified based on the shape and the size of male tarsus I, the morphological characters of males (e.g., pedipalpal segments, genitalia) and rarely the shape of the cribriform plates of females (Nassirkhani and Shoushtari 2014). The genus Dactylochelifer currently contains 45 species (not including the present study), of which 28 species are distributed in the Middle East, Caucasia and the adjacent areas (Table 2) (Harvey 2013;Gao and Zhang 2012). According to the shape and size of the male tarsus I, the species recorded from the Middle East, Caucasia and the adjacent areas can be divided to two informal groups (Table 3): the species belonging to one of them are characterized by their slender and minor modified fore-tarsus, and the members of the other group can be recognized based on their stout and highly modified fore-tarsus (see references mentioned in Table 3). ...
