SRE Status - definitions

SRE category* Criteria Typical representatives

Confirmed

Confirmed or almost certainly SRE;

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
