A Key to the Genera of Endeostigmata and Sphaerolichida

This is a key to the genera of primitive acariform mite groups Endeostigmata and Sphaerolichida written and compiled by Dr David Evans Walter of Colorado State University and the University of Alberta with the assistance of Dr Heather Proctor of the University of Alberta.

Endeostigmatans are common in many habitats, but seem to reach their highest abundances in extreme habitats such as deserts, beaches, and polar regions. As far as is known, these mites are fungivores, algivores and predators on small invertebrates such as nematodes, tardigrades, and mites.  None are considered economically important pests.  They are most likely to be intercepted in goods containing soil, especially dry soils including sand, lichens, mosses or other materials associated with dry or otherwise extreme habitats, including anthropogenic accumulations of dust.

Diatom Identification Key for South African Rivers V2.0

A key to the common and some endemic species of diatoms occurring in South African rivers. Use of the key may be constrained by the absence of endemic species from the Western Cape and KwaZulu Natal provinces.

Orders, Suborders & Cohorts of Mites in Soil

The taxonomy of mites is in a state of flux.  About two dozen major taxa of mites living in soil are currently recognised and variously designated as superorders, orders, suborders (cohorts) or infraorders.  This key allows identification of these groups and also can be used by beginners for determining which of the more advanced family keys are appropriate.

Beetles of the World

Beetles (order Coleoptera) are the most diverse and species-rich group of animals in the world. This fully-illustrated key allows users to identify adult beetles to the level of family, subfamily, and often to genus. To ask questions or report an error, please contact

Australian Soft Scale (Coccidae) Genera

This is the first key to the known genera of Australian soft scales (Sternorryncha: Coccoidea: Coccidae). About 80 described species of soft scales in 26 genera have been recorded from Australia (Ben-Dov et al. 2009). The real diversity of Australian soft scales in poorly known; most Australian specimens can not be identified to genus (Gullan and Hodgson 1998). Froggatt (1921) was the last to review the fauna comprehensively. Hodgson (1994) described and illustrated the type species of each soft scale genus recognized at that time, and provided keys to subfamilies and genera, but the keys are based on only the type species of each genus. Therefore, they fail to capture the morphological diversity in each genus and many specimens cannot be properly identified. Since 1994 a number of new Australian genera have been erected.  This key should permit relatively painless generic identification of properly slide-mounted specimens of described species known to occur in Australia. In many cases, specific identification should also be possible with this tool; several genera are monotypic, and if a dichotomous key to species was previously available for a particular group we have included it in the HTML document for each genus.  PJ Gullan and CJ Hodgson have been working for some time on a revision of the Australian soft scales. One issue in addition to undescribed taxa is that the current classification poorly reflects ancestry. This key should help you to place your query specimen in the context of the present state of classification, flawed though it may be.  All photos by T Kondo.
