This is a key to the major lineages (Classes and Orders) of soil-inhabiting microarthropods. For our purposes this means that arthropods < 1 cm in length as adults are included.

This revised version of Hoddle et al. (2012) has been produced partly to overcome technical problems arising from Java software and partly to incorporate new information and images, together with some additional potentially invasive species.

Information pages are provided to 300 species in 108 genera, with the identification system discriminating 249 species. Of these species, 40 are as yet unrecorded in California but are potential invaders, whether interstate or from overseas.

They have been included for the convenience of quarantine services in USA. In contrast, the Thysanoptera fauna of the American continent north of Mexico has been estimated to comprise 700 described thrips species (Arnett, 1985), with 147 species recorded from Canada (Foottit & Maw, 2019). This identification system is based essentially on adult females, these being the most commonly collected individuals.

For larval thrips, the only modern identification system is to part of the Thripidae fauna of Europe (Vierbergen et al., 2010).

Key to species of Anasillomos (Insecta: Diptera: Asilidae) following taxonomic revision by Dikow 2015 (doi:http://dx.doi.org/10.3897/BDJ.3.e4652)

Taxonomic scope: Bryophytes

Description: The genus Bryum is one of the most challenging genera of bryophytes. This key contains 47 species known from Switzerland and adjacent countries. Nearly all characters are illustrated with microscopical photographs.

This is a key to adult females of described species of Stratiolaelaps compiled by Dr David Evans Walter of Colorado State University and the University of Alberta.

This key allows identification of all species of the kangaroo paw family (Haemodoraceae) in Western Australia

We are grateful to many friends and colleagues working at the WA Herbarium for supplying diverse data, images, maps, ideas, and taxonomic and computing expertise that have made the development of this data set possible. In particular we wish to thank Rob Davis for photos and taxonomic help, Mike Hislop, Steve Dillon, and Margaret Langley for their help with taxonomic queries. We note that the photographic species images available here come from the WA Herbarium’s online plant information system, FloraBase, and represent the work of a team of dedicated volunteers. The maps, also part of FloraBase, represent specimens held at the WA Herbarium.

This key enables the user to identify the adult Flower Chafers, technically known as Cetoniinae, of New South Wales to species. The Cetoniinae are a subfamily of the family Scarabaeidae, which includes Dung Beetles, Christmas Beetles, Rhinoceros Beetles and Chafers.

This key was created by Chris Reid and Matthew Bulbert, of the Centre for Biodiversity and Conservation Research, Australian Museum, Sydney. The illustrations and key construction are by Matthew Bulbert and the descriptions and taxonomic decisions by Chris Reid.

At present, this key excludes species of the tribe Valgini, which are small and difficult to identify.

The key has been constructed from examination of preserved specimens held at the Museum, or loaned from other institutions, and is the first key for the identification of the New South Wales Cetoniinae. The choice of species is based on locality information taken from the Zoological Catalogue for Australian Cetoniinae (Cassis and Weir, 1992), literature records, advice from colleagues and specimen data held by the Museum.

The key has been designed for people with varying degrees of prior knowledge of beetles, from the general enthusiast to research scientist. The terminology has been kept simple but is supported by a glossary and illustrations.

At the time of writing the authors are unaware of any undescribed or additional described species from New South Wales.

Throughout the key the following abbreviations have been used for Australian states and territories:

• QLD - Queensland
• NSW - New South Wales
• ACT - Australian Capital Territory
• VIC - Victoria
• TAS - Tasmania
• SA - South Australia
• WA - Western Australia
• NT - Northern Territory

This is an interactive key which enables the user to identify to generic level adult beetles of the subfamily Chrysomelinae occurring in New South Wales. The Chrysomelinae belong to the family Chrysomelidae (Leaf Beetles) and are represented by 35 genera in New South Wales.

All genera of Chrysomelinae known from New South Wales are included. At the time of writing the authors are aware of one possibly undescribed genus from this state.

 The cosmopolitan genus Heterospilus contains 280 species in Costa Rica. This key can be used to identify the described species; however, many undescribed species remain.

This key allows identification of the genera of Tetranychinae of most interest to quarantine.
