The first description of the larva of Hirstithrombium Oudemans (Trombidiformes, Prostigmata, Johnstonianidae), with redescription of Hirstithrombium noemiae Feider, based on all active life instars
SYSTEMATIC AND APPLIED ACAROLOGY(2022)
摘要
Hirstithrombium noemiae Feider, 1955, representing one of the eight genera currently assigned to Johnstonianinae, is redescribed based on field-collected adults, deutonymphs and larvae, and also larvae obtained at the laboratory from field-born females. The species is associated with hygric habitats located at higher altitudes. A successful rearing allowed the first matching of heteromorphic instars within the genus known hitherto exclusively from active postlarval forms. A comparison of genera of Johnstonianinae, including species known from larvae and/or active postlarval forms is provided, species presently assigned to subfamily are listed and the key characters used in species diagnosing are discussed. A female of Hirstithrombium noemiae Feider, 1955 collected in Turkey is designated as neotype.
