Two new species of the genus Trichogalumna (Acari: Oribatida: Galumnidae) from China

Abstract

Two new species of oribatid mites of the genus Trichogalumna Balogh, 1960 (Acari: Oribatida: Galumnidae), Trichogalumna pseudoohkuboi sp. nov. and Trichogalumna vittateata sp. nov. are described from China based on adult morphology. Trichogalumna pseudoohkuboi sp. nov. can be distinguished from other closely related species by the very small porose areas A2 and A3 on the notogaster, the surface of gnathosoma with large granules, five pairs of epimeral setae and epimeral setal formula 1-0-2-2, wide granular band on notogaster with the central part extending forward, the base of pteromorphs smooth, the surface of notogaster porose areas without stripes and the surface of genital plate with stripes. Trichogalumna vittateata sp. nov. is characterized by notogaster with four pairs of very small porose areas, the presence of longitudinal stripes on prodorsum, and the surface of pteromorphs with distinct ridge-like stripes.
