Abstract An overview of the systematics of smaller arachnid orders (Opilioacariformes, Ricinulei, Palpigradi, Uropygi, Amblypygi, Schizomida, Solifugae and Pseudoscorpiones) is provided, along with data on numbers of recognized families, genera and species for each group. The micro-diverse orders, Opilioacariformes (1 family, 9 genera, 19 species), Ricinulei (1 family, 3 genera, 55 species), Palpigradi (2 families, 6 genera, 78 species), Uropygi (1 family, 16 genera, 103 species), Amblypygi (5 families, 17 genera, 136 species) and Schizomida (2 families, 34 genera, 205 species), are amongst the smallest of all terrestrial arthropod orders. The meso-diverse orders, Solifugae (12 families, 140 genera, 1,087 species) and Pseudoscorpiones (24 families, 425 genera, 3,239 species)—along with the Scorpiones (1,279 species) and Opiliones (c. 6,000 species) which are not dealt with in this contribution—are dwarfed by the three mega-diverse arachnid orders, Araneae (c. 36,000 species), Parasitiformes and Acariformes (with a combined total of c. 48,000).

• A phylogenetic analysis of the arachnid orders based on morphological characters (2007, background): “The opilioacariform mites (nine genera, 20 spp.) (Harvey, 2002) are generally regarded as plesiomorphic Acari and are fairly conserved in their morphology.”
• Short-range endemism amongst the Australian fauna: some examples from non-marine environments (2002, background): “The arachnid order Schizomida consists of some 200 species in 37 genera (Harvey 2002).”
• Identifying conserved genomic elements and designing universal bait sets to enrich them (2017, background): “The arthropod groups Arachnida, Coleoptera, Diptera, Hemiptera and Lepidoptera are among the most diverse invertebrate classes/ orders, encompassing more than 900 000 species (Harvey 2002; Zhang 2011).”
