Taxonomic data on two species of oribatid mites of the family Galumnidae (Acari, Oribatida), with additions to the fauna of China 

Sergey G. Ermilov, Chi-Man Leong


The present study is based on oribatid mite materials (Acari, Oribatida) collected from Macao SAR, southern China during 2016 to 2018. A list of identified taxa, including 25 species from 23 genera and 14 families, is presented; of these, 11 species and 1 genus are recorded for the first time in the fauna of this country, and 1 species is recorded for the first time in the Oriental region. The taxonomic data on two species of the family Galumnidae is provided. A new species, Dimiodiogalumna ilhaverdeensis Ermilov sp. nov. is described; it differs from Dimidiogalumna comoroensis Mahunka, 1994 by the presence of four pairs of notogastral porose areas and one strium on genital plates, and the absence of ridges on anal plates. The systematic placement of Acrogalumna bipartita Aoki & Hu, 1993 is discussed, resulting in the following taxonomic proposal: Allogalumna bipartita (Aoki & Hu, 1993) comb. nov.; the supplementary description of this species is presented based on specimens from China.
