A reappraisal of some basal lineages of the family Macrochelidae, with the description of a new genus (Acarina: Mesostigmata)

摘要

Macrocheles analis Hyatt & Emberson is redescribed and assigned to a new genus, Reductholaspis gen. nov. Longicheles Valle is separated from the genus Geholaspis Berlese and given generic rank, based on a complex of strongly autapomorphic features anda possible synapomorphy with Reductholaspis. The new tribe Geholaspini, including the genera Dissoloncha Falconer, Geholaspis, Longicheles, and Reductholaspis is described and a key to the genera is provided. The genus Macrholaspis Oudemans and the subgenus Nothrholaspis Berlese of Macrocheles Latreille are reinstated at the generic level, based on distinctive synapomorphies of the included species. Scleritholaspis Masan is newly synonymised with Nothrholaspis. Lists of included species are provided for each of the genera discussed. Proposed new combinations are: Longicheles bianchii (Valle & Mazzoleni),-L. lagrecai (Valle), L. ilvana (Valle & Mazzoleni), L. longisetosus (Balogh), L. longulus (Berlese), L. mandibularis (Berlese), L. ranzii (Valle & Mazzoleni), Reductholaspis analis (Hyatt & Emberson), Nothrholaspis banaticus (lavorschi), N. caucasicus (Bregetova & Koroleva), N. coenosus (Takaku), N. shennongjianensis (Ma & Liu), N. subcoenosus (Takaku), N. submotus (Falconer), Macrholaspis beieri (Johnston), M. carpathicus (Masan), M. georgicus (Bregetova), M. morikawai (Ishikawa), M. recki (Bregetova & Koroleva), M. reductus (Petrova), M. similiopacus (Masan), M. stammeri (Kjauss), M. terreus (Canestrini & Fanzago), M. tianschanicus (Bregetova).
