Ahlbergia inopinata Omelko, incertae sedis

(Figs. 130–138)

Ahlbergia inopinata Omelko, in Omelko & Omelko 1995: 218, figs. 1–6 for habitus, characters and larva, figs. 7–8 for male and female genitalia, TL: 18 km southeast from Ussuriisk, Primorskii Krai province, Russia; Korshunov 1996: 43, synonymy for A. tricaudata aquilonaria; Tuzov 2000: 118, synonymy for A. frivaldszkyi aquilonaria .

Material. None

Taxonomy. Korshunov (1996) treated A. inopinata as a synonym of A. frivaldszkyi aquilonaria; this opinion is supported by the wing-characters of a male paratype (Figs. 130–131) preserved in the Siberian Zoological Museum, Novosibirsk, Russia and the male genitalic characters originally illustrated (Omelko & Omelko 1995: 222, fig. 7; reproduced herein as Fig. 133). However, the female genitalia of A. inopinata as originally illustrated (Omelko & Omelko 1995: 222, fig. 8; reproduced herein as Fig. 138) resemble those of A. leei instead of A. frivaldszkyi . In the original description of A. inopinata, the male holotype was not figured, and the specimen with male genitalia figured was not specified. Thus a final conclusion cannot be made from the original description. The holotype needs to be re-examined in the future. If the association of male and female genitalia in the original description is correct, A. inopinata should be regarded as a real species distinct from A. frivaldszkyi and A. leei . On the other hand, there is a possibility that Omelko & Omelko (1995) mixed specimens belonging to A. frivaldszkyi and A. leei in their work and regarded them as a single species.

Distribution. Russia (Ussuri).
