<i>Elachista deriventa</i> sp. n. (Lepidoptera, Elachistidae: Elachistinae), a new species from southern Finland

Abstract

Elachista (Elachista) deriventa Kaila &amp; Mutanen sp. n. is described on the basis of specimens collected in southern Finland. The new species inhabits shady forests and Calamagrostis arundinacea is recorded as its host plant. The species is closest to E. elegans Frey, but differs from that by details in morphology and life history. Diagnostic characters and illustrations are provided for close relatives.

Wide-ranging barcoding aids discovery of one-third increase of species richness in presumably well-investigated moths

“…This is because of the large number of species (130 species described worldwide), small size (wingspan typically 5–12 mm), drab coloration, generally little differentiation in external morphology, and subtle differences in genitalia (Figure 1, where a maximum of variation in appearance and morphology within the group is shown). They have nevertheless been the subject of thorough morphology-based taxonomic investigations during the past decades44454647484950515253545556 covering the fauna of the whole Palearctic region, although the European part of the region is evidently better investigated than that of other areas. As species of E. bifasciella group show close similarity in their morphology, an assumption that the species have diverged quite recently seems plausible.…”

“…Notes: This species was erroneously recorded from Crimea and Zaporozhie region as Elachista elegans Frey, 1859 (BUDASHKIN & SINEV, 1991, BIDZILYA et al, 2003, BUDASHKIN, 2004, 2006. Material from Crimea (Karadagh Nature Reserve) has been authentically re-determined by L. Kaila (KAILA et al, 2008), hence E. elegans must be removed from both Crimea and Ukraine.…”
