Species spotlight II

Truncatellina callicratis (Scacchi, 1833)
Lunzjata, Malta

Truncatellina callicratis (Scacchi, 1833) is the smallest landsnail in Malta and the only recent representative of its family, the Vertiginidae. Never exceeding 2mm in length, it is found in large (though localized) populations in leaf litter of trees such as Ceratonia siliqua (Carob Tree/ Ħarruba), such as the one below in Lunzjata, Rabat:

The species is probably under-recorded due to its small size and habitat restrictions.

Shell identification
  • about 2mm
  • about as twice long as it is wide
  • compact cylindrical shape
