Reductholaspis Emberson is rediagnosed with the description of a new species, Reductholaspis longicorniculussp. nov. Shen & Yi from southwestern China. This is the first report of the genus Reductholaspis from the Oriental Region and the first described male for the genus. Reductholaspis longicorniculussp. nov. is distinguished from R. analis Hyatt & Emberson by the dorsal shield with 28 pairs of setae, posterior margin of the sternal shield with deep hollows lateral to iv2, latigynal sclerites well developed, metasternal plates ovate, all setae on coxae I–IV pilose, tarsus I with proximal pilose setae, and three pairs of lightly sclerotized platelets between the epigynal shield and anal shield.

This paper describes three new species of genus Cunaxoides, namely, C. reticulatus Chen & Jin sp. nov., C. kanasensis Chen & Jin sp. nov. and C. allokanasensis Chen & Jin sp. nov., which are described and figured from Xinjiang Uygur Autonomous Region, China. [ABSTRACT FROM AUTHOR]

Five species of Unionicola Haldeman, 1842 (Acari: Hydrachnidia: Unionicolidae) were collected between 2018 and 2019. Notably, Unionicola (Armatax) armata Walter, 1929, previously unrecorded in China, is now documented for the first time in the country. Additionally, Unionicola newsumi Wiles, 1999 has been reclassified and assigned to the new subgenus Vespicola within the genus Unionicola Haldeman, 1842. These findings also led to the establishment of three new subgenera: Micronodusgen. nov., Vespicolagen. nov., and Lingshuiataxgen. nov. including four species: Unionicola soluplatussp. nov. U. jinisp. nov. U. caudipessp. nov. and U. armatallasp. nov. This marks the first description and documentation of these subgenera and species. [ABSTRACT FROM AUTHOR]

The genus Lepidocunaxoides (Acariformes: Cunaxidae) is recorded for the first time from China and the generic diagnosis is revised on the basis of both sexes of a new species, Lepidocunaxoides bomiensis Chen & Jin sp. nov.. The new species differs from the known species Lepidocunaxoides robustus Kalúz & Ermilov, 2019 by follows: palpal tibiotarsus claw unbranched apically and tibiotarsus with a proximal bifurcated seta; cheliceral seta and adoral setae absent; propodosomal shield concave anteromedially; tibia II with one bsl. Cunaxoides neopectinatusShiba, 1978 is transferred to Lepidocunaxoides based on the generic concept. [ABSTRACT FROM AUTHOR]

The male of Scutascirus triangulumLin, Zhang & Ji, 2001 is described for the first time. [ABSTRACT FROM AUTHOR]

A key to adult females of Neoscirula species of the China is provided. [ABSTRACT FROM AUTHOR]

A new spleenwort species, Asplenium guodanum, was found and described from Danxia landform region in Guangdong, China. The new species has close resemblance to A. subcrenatum Ching ex S.H.Wu in morphology, but can be distinguished by having plants small, stipes and rachises not covered with fibrous scales, relatively fewer pairs of pinnae, pinnae short, pinna margin weakly biserrate, pinna apex acute and lower pinnae obviously reduced. Phylogenetic analyses, based on six plastid markers (atpB, rbcL, rps4 & rps4-trnS and trnL & trnL-F) of the new species and its relatives, support a close relationship between A. guodanum and A. subcrenatum. Only one population with no more than 50 individuals were found and, therefore, it is recommended to be classified as Critically Endangered (CR) following IUCN Red List Criteria.

A brief introduction of Chinese Limnesiidae taxonomy is provided. Adults of two new species, Limnesia (Limnesia) lupingae Li & Guo sp. nov. and Limnesia (Limnesia) macrophthalma Li & Guo sp. nov., from Heilongjiang and Hubei provinces respectively, are described in detail. Subtle structures are recorded with scanning electron micrographs. In addition, deutonymphs of two new species are also described in detail and compared with the adults in discussion.

The female and male of Parasitus quadrichaetus Ma & Cui, 1999 are described for the first time. They show that this species is correctly placed in Parasitus sensu lato and not Coprocarpais Hrúzová & Fenďa, 2018. The deutonymph is also redescribed in detail. [ABSTRACT FROM AUTHOR]

Two new species of genus Cunaxa, namely, C. papilla Chen & Jin sp. nov. and C. striata Chen & Jin sp. nov. are described and illustrated. C. papilla Chen & Jin sp. nov. was collected in Ruyuan Yao Autonomous County, Shaoguan City, Guangdong province, China.

C. striata Chen & Jin sp. nov. was collected in Qingchuan County, Sichuan province and Zhaoqing City, Guangdong province, China. It's similar to C. yaylensisSergeyenko, 2009, but differs from it by the propodosomal shield with broken striae, c1 longer than or equal to f1 and h1 in length, f1 extending beyond the base of h1 and two pairs of hysterogastral setae (hgs1–hgs2).

This paper deals with a new species of genus Parabonzia and newly recorded genus Bonzia from China. Parabonzia bioxys Chen & Jin sp. nov., which is described and illustrated based on adult females collected from rotten wood in Hainan Province, China, differs from all other Parabonzia by the dorsal seta of the palp telofemur having two tines instead of three or more (most species) or being unbranched (P. mindanensisCorpuz-Raros, 1996). Bonzia halacaroidesOudemans, 1927 is redescribed based on adult females collected from fallen leaves in Jiangxi Province and Chongqing City, China, which represents a newly recorded genus BonziaOudemans, 1927 to China and adds more details and new illustrations to its original description.

Chaetotaxy is an important character especially in mites and can be applied in species diagnosis, phylogenetics, ontogeny, and so on. Chaetotaxic ontogeny of Bdella was carried out through comparing both immature and adult descriptions of eight Bdella species, including a new species, B. xinisp. nov., from China. Based on these species, chaetotaxy changes in Bdella mainly focused on ventral hypostomal setae (vh), setae on palpal basifemur, aggenital setae (ag), genital setae (g), anal setae (ad) and leg setae.
