Unusual juvenile morphology in Galumnidae (Acari, Oribatida): culturing and development of Trichogalumna ohkuboi from Russia
Abstract
The oribatid mite species Trichogalumna ohkuboi Hagino, Bayartogtokh & Shimano, 2017 (Oribatida, Galumnidae) is recorded for the first time in Russia. Duration of development from larva to adult is 17–24 days at ≈25ºC while feeding on fungi (Alternaria sp.) and algae (Pleurococcus sp.), in laboratory conditions. The active juvenile instars are characterized by the unusual (among known juvenile Galumnidae) morphology, e.g., foveolate ornamentation of the dorsal side and posteroventral part (except LA) of the gastronotum, and the morphology of the lamellar, interlamellar, and some gastronotic setae (well developed, dilated distally). The provided data on the morphology of the juvenile instars of T. ohkuboi are the first comprehensive ones for any member of this genus.
