An illustrated species key of Enclisis Townes including descriptions of two new species (Hymenoptera: Ichneumonidae)

Abstract

Two new species of Enclisis Townes, 1970 from Spain and the Balkan Region are described and illustrated: E. castellana sp.n. and E. balcanica sp.n.. Females of the new species are distinguished between, and from the closest species E. ornaticeps by microsculpture of first lateral area of propodeum and mesopleuron, head features and body colour. The male of E. balcanica is distinguished from the closest species E. infernator and E. schwarzi by its head, less transversal, and by a longer second metasomal tergite. The male of E. castellana is separated from E. ruficeps by its microsculpture on mesopleuron and mesonotum, always on shiny background, and by the position of the subdiscoideus vein, which reach the postnervulus vein in the middle or above the centre. Furthermore, data on phenology of E. castellana and a new illustrated key for Enclisis species, excluding E. nigricoxis and E. ruficoxis, is provided. The species E. alpicola, E. ornaticeps and E. macilenta are recorded for the first time from the Bulgarian fauna. E. infernator is the first record from Bulgaria and Spain.
