Formerly designated Calvatomina nr. superba, Jordanathrix nr superba resembles but is distinct from Dicyrtomina superba from New Zealand (which does not occur in the UK). Thought to be a relatively recent introduction to the UK, first recorded about 10 years ago. Similar to Dicyrtomina ornata but in D. ornata the eyepatch is uniformly dark; in this species the dark ocelli are on an lighter eyepatch with a reddish background colour.
