Scorpion-flies of the Panorpa cognata-complex in the western palaearctic region (Mecoptera)

Summary

The Panorpa cognata-complex comprises four morphologically distinct species two of which, P. cognata and P. meridionalis, show a confusing degree of variation. P. meridionalis is separated by the bi-lobed ventral parameres, which are singlelobed in P. cognata, P. annexa and P. etrusca. P. meridionalis is also allopatric and has two geographical forms which may prove to be biologically distinct species. P. cognata is sympatric with, and closely related, to P. annexa. P. cognata and P. etrusca are also sympatric. There is a clear morphological and distributional division between P. annexa and P. etrusca, for which reason the latter is raised to species level. Based on morphological evidence P. ghilianii, P. cognata osellai and P. adnexa [sic] var. subalpina are synonymized with P. cognata and P. meridionalis var. commissa, P. meridionalis var. germanizans and P. meridionalis var. liberata are synonymized with P. meridionalis.
