was described from three males collected in Malta in March 1952 by C. De Lucca (Amsel, 1954). The holotype and one paratype were kept in the collection of Carmello De Lucca. After his death in 1971 the collection stayed with the family and was not curated, with the result that it suffered much from attack by pest insects (P Sammut in litt.). With the help from Paul Sammut we were able to borrow these two type specimens, but only the pins and labels were left - apart from the tip of the abdomen of the holotype, from which an almost complete genitalia slide could be prepared, however, leaving the apex of the phallus broken. The second paratype in SMNK is in relatively good condition.
