Chondrodesmus cf riparius Carl, 1914

Status

GB IUCN status: Not applicable (non-native)

Identification

In Europe, adult females may reach 6 cm long and 9-10 mm wide, males are slightly smaller, about 5 cm long and 8 mm wide (Enghoff, 2008). To date, the only British specimens measured were immature but sizes of about 4 cm long and 6.5 mm width are in line with the continental examples. Apart from size, the appearance of the millipede is distinctive amongst British species, the yellow paranota contrasting strikingly with the reddish-brown body.

Distribution and Habitat

Chondrodesmus riparius was described from Colombia in 1914 but seems not to have been seen in its native habitat since then. Scattered records of Chondrodesmus c.f. riparius began to be reported from northern Europe from 2000 (Enghoff, 2008), all linked to indoor potted plants. The only British records to date are from Manchester in 2011, the West Midlands in 2014 and Bexhill in 2018 and 2019. As with the continental finds all the British millipedes appear to have been imported in large potted plants.
