Paracorymbia antiqua Vitali, 2005 View in CoL
( Fig. 1 View Fig )
Examined material. Holotype, female, Baltic amber, ex coll. C. Gröhn, author’s coll. FS3BS3 ( Fig. 1 View Fig ); female, Baltic amber, ex coll. M. Veta; author’s coll. FS73BS42.
Differential diagnosis
As remarked in the original description (Vitali 2015), Paracorymbia antiqua shows pronotum with apical furrow and truncate elytral apex like Paracorymbia . However, it differs from all congeners of the Recent in the convex under margin of the eyes (concave in the extant species). This archaic
190 character is almost present in the extant species of the genus Vadonia Mulsant, 1863 , which however show rounded elytral apex and pronotum without apical collar.
Female genitalia (exposed in the holotype) are analogue to the ones of the extant Vadonia and Paracorymbia .
Due to its mixed characters, P. antiqua was interpreted as a quite archaic member of Paracorymbia , close to the pallens- group and as a probable link with Vadonia .
However, considering that this species can be inserted in neither extant subgenera ( Miroshnikov 1998a, b), Vadoniocorymbia n. subgen. is here introduced to accommodate this fossil species.
