Paidia minoica sp. n. von Kreta, eine neue Paidia für Europa. Beschreibung und Angaben zur Phänologie der Art (Lepidoptera: Arctiidae, Lithosiinae)

摘要

Paidia minoica sp. n. (Arctiidae, Lithosiidae) is described from the island of Crete (Greece) and assigned to the Paidia rica (Freyer, 1858) - species group. Previously, the Cretean island populations were considered to fall under the species concept of Paidia cinerascens (Herrich-Schaffer, 1847). Although in habitus and external morphology there are no valuable differential features from P. cinerascens, constant and significant differences in male genitalia between Paidia cinerascens and the new species support species status of the latter. So far, all Paidia species were considered to be univoltine. Bivoltinism is reported now for the first time in this genus: lowland populations of Paidia minoica sp. n. regularly fly from May to June and, again, in October, whilst populations at higher elevations are characterised by one unique main flight period from late July to late September. This phenomenon needs further investigations, but it is likely that population dynamics of this species are complex, including bivoltinism, univoltinism, staggered development of larvae and, possibly, separate 'races' with different phenologies. Paidia minoica sp. n. is thennophilous and occurs from the lowlands up to 1,400 m above sea-level, preferring forest fringes, wide forest clearings and fringes of shrub-land on rocky soils.%Paidia-Populationen Kretas, bisher als zu Paidia cinerascens (Herrich-SchäFFER, 1847) gehörig betrachtet, werden als eigenständige Art erkannt und als Paidia minoica sp. n. beschrieben. Die Differentialanalyse zu den nächstverwandeten Arten der Paidia rica (Freyer, 1858)-Artengruppe berücksichtigt äußere und innere morphologische Merkmale. Paidia minoica tritt in niederen Lagen in 2 Generationen auf. Dies ist der erste Nachweis einer zweibrütigen Entwicklung für die Gattung Paidia HÜBNER, 1819.
