Abstract
The analysis of mitochondrial COI data for the European-Centroasian montane Udea alpinalis species group finds deep intraspecific splits. Specimens of U. austriacalis and U. rhododendronalis separate into several biogeographical groups. These allopatric groups are not recovered in the analyses of the two nuclear markers wingless and Elongation factor 1-alpha, except for U. austriacalis from the Pyrenees and the French Massif Central. The latter populations are also morphologically distinct and conspecific with Scopula donzelalis Guenée, 1854, which is removed from synonymy and reinstated as Udea donzelalis (Guenée, 1854) stat. rev. Furthermore, Udea altaica (Zerny, 1914), stat. n. from the Mongolian central Altai mountains, U. juldusalis (Zerny, 1914), stat. n. from the Tian Shan mountains of Kazakhstan, Kyrgyzstan and NW China, and U. plumbalis (Zerny, 1914), stat. n. from the Sayan Mountains of Northern Mongolia are raised to species level, and lectotypes are designated. Evidence of introgression of U. alpinalis into U. uliginosalis at three localities in the Central Alps is presented. A screening for Wolbachia using the markers wsp, gatB and ftsZ was negative for the U. alpinalis species group, but Wolbachia was found in single specimens of U. fulvalis and U. olivalis (both in the U. numeralis species group). We do not find evidence for the conjecture of several authors of additional subspecies in U. rhododendronalis, and synonymise U. rhododendronalis luquetalis Leraut, 1996, syn. n. and U. r. ventosalis Leraut, 1996, syn. n. with the nominal U. rhododendronalis (Duponchel, 1834).
Highlights
With currently 217 recognised species (Nuss et al 2003–2018), Udea Guenée, 1845 is the most diverse genus of Spilomelinae within Crambidae. Munroe (1966) revised the North American species of Udea. Mally and Nuss (2011) proposed a phylogenetic framework for the majority of the 39 currently recognised European species and described four monophyletic species groups: the U. ferrugalis, U. itysalis, U. numeralis and U. alpinalis species groups
A screening for Wolbachia using the markers wsp, gatB and Filamenting temperature-sensitive mutant Z (ftsZ) was negative for the U. alpinalis species group, but Wolbachia was found in single specimens of U. fulvalis and U. olivalis
Investigate, and, where possible, explain this unsettled question of intraspecific diversity of U. rhododendronalis, U. austriacalis and the U. uliginosalis-U. alpinalis species pair
Summary
With currently 217 recognised species (Nuss et al 2003–2018), Udea Guenée (in Duponchel), 1845 is the most diverse genus of Spilomelinae within Crambidae. Munroe (1966) revised the North American species of Udea. Mally and Nuss (2011) proposed a phylogenetic framework for the majority of the 39 currently recognised European species and described four monophyletic species groups: the U. ferrugalis, U. itysalis, U. numeralis and U. alpinalis species groups. With currently 217 recognised species (Nuss et al 2003–2018), Udea Guenée (in Duponchel), 1845 is the most diverse genus of Spilomelinae within Crambidae. Whereas the first three species groups are represented on other continents, the U. alpinalis group occurs, to the present knowledge, only in the mountain systems from Europe to Central Asia. This group contains nine species: Udea alpinalis (Denis & Schiffermüller, 1775), U. austriacalis (Herrich-Schäffer, 1851), U. bourgognealis Leraut, 1996, U. carniolica Huemer & Tarmann, 1989, U. cretacea (Filipjev, 1925), U. murinalis (Fischer von Röslerstamm, 1842), U. nebulalis (Hübner, 1796), U. rhododendronalis (Duponchel, 1834), U. uliginosalis (Stephens, 1834). U. uralica Slamka, 2013 exhibits the group-specific apomorphies (see below) and is here added to the U. alpinalis group
