Abstract
Two new species, Pergalumna clava n. sp. and Pergalumna pilosus n. sp., and a newly recorded species, Pergalumna amamiensis Aoki, 1984 of oribatid mites are described and illustrated from China. Pergalumna clava n. sp. is different from most known species of Pergalumna in the dorsosejugal suture complete; developed four pairs notogastral porose areas, Aa transverse irregular wedge; short interlamellar seta and bothridial seta clavate. Pergalumna pilosus n.sp. different from most known species of Pergalumna in the dorsosejugal suture complete; Aa porose area transverse irregular wedge; longer interlamellar barbed; median pore and postanal porose area present.
Highlights
Pergalumna was proposed by Grandjean, 1936 with Oribata nervosa Berlese, 1914 as type species
During taxonomic identification of oribatid mites from China, we found two new species, Pergalumna clava n. sp. and Pergalumna pilosus n. sp. and a newly recorded species, Pergalumna amamiensis Aoki, 1984
The main goal of this study is to describe the new species, give a supplementary description to Pergalumna amamiensis and illustrate these species
Summary
Pergalumna was proposed by Grandjean, 1936 with Oribata nervosa Berlese, 1914 as type species. The genus is one of the largest genera of the family Galumnidae, which comprises two subgenera, 169 species and 14 subspecies, and collectively have a cosmopolitan distribution (Ermilov and Klimov, 2017; Subías, 2004, updated 2020). 15 species and 4 subspecies of Pergalumna were recorded in China (Chen et al, 2010; Zheng et al, 2019; Subías, 2020). During taxonomic identification of oribatid mites from China, we found two new species, Pergalumna clava n. A newly recorded species, Pergalumna amamiensis Aoki, 1984. The main goal of this study is to describe the new species, give a supplementary description to Pergalumna amamiensis and illustrate these species
