Tydeinae of the world: generic relationships, new and redescribed taxa and keys to all species. A revision of the subfamilies Pretydeinae and Tydeinae (Acari: Actinedida: Tydeidae) - part IV

• Andrzej KAŹMIERSKI

Abstract:

A total of 254 species of the subfamily Tydeinae are discussed or placed in the keys, including 64 new combinations and 24 species described as new to science: Afrotydeus novaezealandiae sp. n., A. smileyi sp. n., A. zairensis sp. n., Lorryia akelai sp. n., L. amica sp. n., L. blaszaki sp. n., L. bloszyki sp. n., L. danhidalgoi sp. n., L. draciformis sp. n., L. elegans sp. n., L. globulipalpa sp. n., L. incomperta sp. n., L. jesionowskii sp. n., L. nobila sp. n., L. ornata sp. n., L. perlata sp. n., L. septuagesimusseptima sp. n., L. sherekhani sp. n., L. snajperi sp. n., Melissotydeus incarum sp. n., Metalorryia foliata sp. n., Neolorryia americana sp. n., Neoapolorryia hippocastani sp. n., and Tydeus helenipanoue sp. n. Twelve species are redescribed: Lorryia brevicula (KOCH, 1838), L. concinna (OUDEMANS, 1929), L. italica (OUDEMANS, 1928), L. longina (KAŹMIERSKI, 1980), L. pulchra (OUDEMANS, 1929), L. raphignathoides (BERLESE, 1910), L. reticulate (OUDEMANS, 1928), L. turrialbensis BAKER, 1968, Metalorryia cristata (KARG, 1975), M. insignita (KUZNETZOV, 1971), M. palpsetosa (KARG, 1975) and Neoapolorryia regia (KUZNETZOV, 1973). Four synonyms and three homonyms are designated. The new synonyms are as follow: Tydeus inflatus MOMEN, 1988 = Lorryia pulchra (OUDEMANS 1929), Tydeus magnanus KARG, 1975 = L. obstinata (LIVSHITZ, 1973), Tydeus octomaculatus MOMEN & LUNDQVIST, 1995 = L. unigena (LIVSHITZ, 1973) and Metalor­ryia cristata (KARG, 1975) = M. delicata (KUZNETZOV, 1971 ). In addition, 64 species are specified as “ancient” species, i. e. impossible to determine according to the present sys­tematic standards. The morphology of Tydeinae is discussed. The nomenclature of dorsal ornamentation (types and subtypes) is proposed and the keys to all known species are given. The generic relationships are considered and phylogenetic analysis is provided.
