M. Heidemaa 1999: A new sawfly species Caliroa crypta sp nov from Northern Europe (Hymenoptera, Tenthredinidae). - Entomologica Fennica 10: 183-186.
A new tenthredinid species Caliroa crypta sp. nov. is described on the basis of one female from Estonia and one male from Finland. The new species slightly resembles C. tremulae Chevin but the sculpture of its abdominal terga is alutaceous- coriaceous like that in Endelomyia aethiops (Fabricius). The host plant and larva of the species are unknown.
