Redescription of hypoaspisella pini (Hirschmann, bernhard, greim and gÖtz) comb. n. (acari: Mesostigmata: Laelapidae) with a key to world species of hypoaspisella with setae st1 off sternal shield

Abstract

Hypoaspisella pini comb. n. is redescribed based on adult females collected from a rotten stump of Siberian spruce (Picea obovata Ledeb.) in Western Siberia (Russia) and from the galleries of Ips acuminatus (Gyllenhal) (Coleoptera: Curculionidae: Scolytinae) in Turkey. Hypoaspisella pini fits well with the current concept of the genus Hypoaspisella Bernhard. The chelicerae of this species are similar to those of free-living forms, which suggests it may be a predator of small invertebrates, inhabiting bark beetle galleries and decomposing organic matter. Moreover, we provide a world key to the species of Hypoaspisella with setae st1 off sternal shield.
