Spider mites: their biology, natural enemies and control: vol. 1A

Generic and familial concepts of the Ascidae Voigts and Oudemans (= Blattisociidae Garman, Aceosejidae Baker and Wharton) are reviewed and modified from a world standpoint. The postembryonic developments of chaetotactic and external morphological features of the body and appendages are discussed. Twenty-two genera in three subfamilies are recognized, keyed, and defined: Arctoseius Thor, Iphidozercon Berlese, Xenoseius nov., and Zerconopsis Hull in the Arctoseiinae Evans; Cheiroseius Berlese and Platyseius Berlese in the Platyseiinae Evans; Aceodromus Muma, Antennoseius Berlese, Arctoseiodes Willmann, Asca Heyden, Blattisocius Keegan, Diseius nov., Gamasellodes Athias-Henriot, Hoploseius Berlese, Lasioseius Berlese, Leioseius Berlese, Melichares Hering, Neojordensia Evans, Proctolaelaps Berlese, Protogamasellus Karg, Rhinoseius Baker and Yunker, and Zercoseius Berlese in the Ascinae Voigts and Oudemans.Newly synonymized genera are Hyattella Krantz under Lasioseius, Mucroseius Lindquist and Orolaelaps DeLeon under Melichares, Garmaniella Westerboer under Proctolaelaps, and Tropicoseius Baker and Yunker under Rhinoseius. Genera removed from the Ascidae include Africoseius Krantz, Digamasellus Berlese, Laelaptoseius Womersley, and Zygoseius Berlese.Modified systems of nomenclature based on holotrichous Gamasina are introduced and applied to setae on the dorsum of the idiosoma and on the venter of the opisthosoma.

Taxonomic Concepts in the Ascidae, with a Modified Setal Nomenclature for the Idiosoma of the Gamasina (Acarina: Mesostigmata)

The chaetotactic nomenclature proposed by Lindquist and Evans (1965) for the Gamasina, using the family Ascidae as examplar, is adopted for use in the family Phytoseiidae. Probable setal homologies were determined by: examining and comparing ontogenetic relationships in both the Phytoseiidae and Ascidae; standardizing the shape and size of the dorsal shield of exemplars from 7 genera of Phytoseiidae and one of Ascidae in order to compare standardized, transformed setal positions; examining the spatial relationships between setal and pore positions. The technique used to standardize the shape and size of the dorsal shield is described. The setal nomenclature adopted for each of the genera of Phytoseiidae is discussed and presented in diagrammatic form. Ventral chaetotaxy in the Ascidae and Phytoseiidae is also discussed.

The determination of setal homologies and setal patterns on the dorsal shield in the family phytoseiidae (acarina: mesostigmata)

This work provides a practical guide to the external morphology and classification of the mesostigmatic mites of Britain and Ireland. In the account of the external morphology, particular attention is paid to those features which figure prominently in modern classifications of the Mesostigmata, such as, the structure of the gnathosoma, the ontogenetic development of the chaetotaxy of the idiosoma and legs, and the form of body sclerotization. The Order Mesostigmata is represented by five suborders in the fauna of Britain and Ireland; namely, Gamasina, Antennophorina, Microgyniina, Sejina and Uropodina. Keys, accompanied by illustrations, are provided for the identification of suborders, families and genera. A new genus Cornigamasusgen. nov. (type: Gamasus coleoptratorum var. lunaris Berlese, 1882), family Parasitidae, is proposed. Aspects of the biology of the group are discussed under family or superfamily headings. A brief account is given of the methods of collecting, preserving and preparing mites for study.
