A new record of Peloribates barbatus Aoki, 1977 (Oribatida: Haplozetidae) from Korea

Abstract

According to the catalogue of Subías (2004, Online version 2012), Haplozetidae comprises 19 genera, 11 subgenera, 230 species. The genus Haplozetes was pro­ posed by Willmann (1935) with Peloribates vindobonensis Willmann, 1935 as the type species. Subsequently, Grandjean (1936) redefined the type species, and ascer­ tained generic status of Haplozetes and proposed the fam­ ily Haplozetidae (Ermilov et al., 2013). This family is diagnosed by the movable pteromorphs; rostrum round­ ed; lamellae narrow, without translamella; 10­14 pairs of notogastral setae; four to five pairs of genital setae; mono­ or tridactylous legs (Bayartogtokh, 2010). The genus Peloribates is one of the species rich genera of the family Haplozetidae, and distributed worldwide, about 90 species have been assigned to this genus. They were previously known from widely scattered areas of the most of biogeographical regions of the world. Several species have wide distribution and majorities have been described from Palaearctic, Nearctic and Oriental re­ gions (Bayartogtokh, 2000; Bayartogtokh and Smelyan­ sky, 2008). In Korea, the genus Peloribates is represented by three species, namely Peloribates acutus Aoki, 1961, Peloribates longisetosus Willmann, 1930 and Peloribates rangiroaensis asiaticus Aoki and Nakatamari, 1974 (NIBR, 2013). We found a new species to Korean inventory compar­ ed to the present existing checklist of oirbatid mite from NIBR (2013). In this work, we present a taxonomic di­ agnosis of the genus and species, and morphological characteristics with detailed illustration.
