Fianoniella stenognatha sp. n. from the Columbretes Islands (Castellón, Spain) is described and illustrated. The new species is distinguished by its longer and narrower mandibles with parallel or divergent rims in the apical half, wider clypeus, hind ocelli more separated and closer to the eyes, and longer flagellar segments. Additional notes to complete the original description of the closest species, F. laeviscutum (Horstmann), are given. A key to the European species of Fianoniella is provided.
Two new species of Enclisis Townes, 1970 from Spain are described and illustrated: E. dichroma sp.n. and E. schwarzi sp.n. The new species are distinguished from the closest species E. infernator and E. ornaticeps by head and leg characters and body colour. Data on their phenology and a key to these four European species are presented. External and internal scanning electron microscopy of male tyloids revealed that these structures, in both new species, have a secretory role.
The endemic Costa Rican genus Zurquilla Gauld, 1997, is transferred from the ichneumonid subfamily Tryphoninae (tribe Oedemopsini) to the Cryptinae (tribe Phygadeuontini) and synonymised with Nipponaetes Uchida, 1933. This decision is justified using morphological and molecular (28S D2-3 ribosomal DNA sequence) evidence. We briefly discuss the phylogenetic utility of characters that led to the type species of Zurquilla being described as a tryphonine and provide a host record that indicates that Nipponaetes is a parasitoid of spider egg sacs.
