Although Steve Hopkin's key names this species as Odontella, it is now placed in the genus Superodontella (due to lacking eversible antennal vesicles). The mapped records are for slides labelled 'Odontella sp.', 'Odontella stachi', and 'Odontella empodialis' in the NHML collection. The only species described by Fjellberg (1998) was Odontella lamellifera; in view of his comments regarding the variability of some of the diagnostic characters used by Gisin (1960) to separate Odontella species, all members of this genus recorded from England and Wales will be mapped as Odontella lamellifera 'group' until the species boundaries can be clarified. There are no records of Odontella from Ireland or Scotland.
These bluish-grey animals should be looked for in leaf litter and under tree bark. The longest UK specimen Steven has seen was 1.3 mm in length. There are five ocelli in each eye, and a small post-antennal organ is present (Fig. 1). The empodium on the foot is either absent (Fig. 2) or extremely small and the mucro has two dorsal lobes (Fig. 3). There are two small anal spines at the tip of the abdomen (Fig. 4).
