Styloniscus mauritiensis (Barnard, 1936)


GB IUCN status: Not applicable (non-native)

ID Difficulty



Another very small, reddish species, with a tuberculate body and an eye composed of three ommatidia. However, there are other similar species, such as Cordioniscus stebbingi and S. spinosus occurring in heated glasshouses.

Identification should be based on a male specimen.  A brief description, with figures, is given by Gregory & Lugg (2018).

Distribution and Habitat

Originally known from Royal Botanic Gardens Edinburgh where specimens were collected within peat inside plant pots in a heated glasshouse in 1986 (Collis & Harding, 2007).  It was subsequently refound there in 2015 during the BMIG field meeting and, subsequently, at a few tropical glasshouses in England and Wales (Gregory & Lugg, 2018).

In the wild S. mauritiensis is known from the islands of Hawaii and Mauritius.
