Taxonomy is well known (but not necessarily published)
Group is well represented in collections (in particular from the region in question)
High levels of endemism exists in documented species of the genus/family
Inference is often possible from immature specimens based on locality
Antichiropus millipedes (Paradoxosomatidae)
Aops scorpions (Urodacidae)
Schizomids
Subterranean (i.e. blind) pseudoscorpions
Likely
Taxonomically poorly resolved group
Unusual morphology related to poor dispersal for that group e.g. troglomorphism
Often singletons in surveys
Few, if any, regional records
Opiliones in the genus Dampetrus
Some pseudoscorpions
Some slaters (Philosciidae)
Karaops spiders (Selenopidae)
Potential
Taxonomically poorly resolved group (or specimen cannot be identified to species level)
Often common in certain microhabitats in SRE surveys (i.e. litter dwellers)
Other species within the genus might be widespread
Many mygalomorph spiders
Some centipedes (Cryptopidae; Geophilomorpha)
Some pseudoscorpions
Unlikely
Cannot be identified to species level and taxonomy uncertain, but experience suggests the distribution is unlikely to be restricted.
Current records show a distribution close to 10,000 km2; however when considering collecting bias and standard error, the distribution may exceed this threshold
Indolpium pseudoscorpions
Unknown
So little is known that it does not allow for any suggestion of geographic distribution
Acari
Widespread
Taxonomy well understood
Common and known from areas larger than 10,000 km2
the spider Gaius villosus (Idiopidae)
the millipede Austrostrophus stictopygus
*These categories have been developed through the taxonomic expertise of staff from Phoenix Environmental Sciences and the Western Australian Museum.
