Allantus lateralis Mocsáry, 1909

A senior objective synonym of Tenthredo (Tenthredo) calvaria Enslin, 1912 .

TYPES. Allantus lateralis Mocsáry, 1909: 25 –26. Syntype (s) Ƥ, “Sibiria orientalis: Ussuri (Kasakewitsh)”. Secondary homonym of Tenthredo lateralis Mocsáry, 1909 [= Tenthredo (Tenthredella) contusa (Enslin, 1912)]. Lectotype Ƥ, hereby designated (Fig. 25). Type locality: “Ussuri Kasakewitsch” [= Russia: Khabarovskiy Kray: Kazakevichevo].

= Tenthredo calvaria Enslin, 1912b: 104 . Replacement name for Allantus lateralis Mocsáry, 1909 .

DISCUSSION. Taeger (1988b) mentioned the “ holotype ” of the taxon, but the original status of the only available type was syntype. The specimen is hereby designated as lectotype (Fig. 25). The species belongs to the T. arcuata complex. The validity of the taxa of the complex needs further investigation. Tenthredo calvaria currently seems to be well defined by colouration (Taeger 1988b). Unpublished COI sequence data show a rather weak separation of calvaria from European taxa. On the other hand, nearly all taxa of the T. arcuata complex fall in the same barcoding cluster as the examined calvaria specimens (Barcode Index Number: BOLD:AAD3089). Further studies are needed to confirm the validity of the species.
