A small brown species (to 11mm in length) with distinct paranota on the side of the body and eyes comprising 15 to 17 well pigmented ocelli. It is best identified by dissection of male gonopds.
Descriptions, with figures, are given by Anderson (1996) and Gregory, et al (2015).
Distribution and Habitat
The first Irish records of this introduced species were from County Down and County Antrim in 1994. It now appears to be well established as a naturalised component of the fauna of at least ten sites in Northern Ireland. It was found at RHS Wisley, Surrey in 2011, subsequently from Oxford city, two sites in south Wales and a single locality in Glasgow, Scotland (Gregory, et al., 2015) ). Insufficient habitat data were available for reliable conclusions to be drawn from the recording scheme data analysis but most of the Irish records are from deciduous woodland and Anderson (1996) suggests that deep, stable litter is preferred. The genus in general occurs in woodland but there are few references to the specific habitat of A. pulchella in its native Italy. The few that exist suggest that the Irish sites are typical for the millipede and it is most probably a species of the woodland litter. There is also one record from Mediterranean maquis vegetation (Desmond Kime, pers. comm.) suggesting it may be able to colonise areas of drier scrub in Ireland. The species has been introduced to southern France (Mauriès, 1960) and Maderia (Demange, 1970) as well as Ireland. In Ireland adults have been collected from October to February but there is some evidence of a longer than annual life cycle (Anderson, 1996).
