Ripidius primordialis Stein, 1877 (Figs 4–6) Stein (1877: 29), original description as “ Rhipidius primordialis ”. Type material examined. Lectotype, designated herewith, 1 ♂ MNB (Fig. 4), MB.1.84.1, ‘ Rhipidius primordialis Stein. *’ [handwritten] // ‘[hand drawn red circle with a thick dot in the centre] Holotyp [handwritten in red] MB.1.84.1 [handwritten] Paläontologisches Museum Berlin [printed, underlined] Rhipidius primordialis Stein, 1877 Orig. J.P.E.F. STEIN (1877): Drei merkwürdige Bernstein-Insekten.- Mitt. Münchener Entom. Ver. 1877, 1, S.30 [handwritten]’, Eocene Baltic amber originating from Palmnicken (now Yantarny), Sambia Peninsula. New material examined. 1 ♂, NHMD 675485 (formerly labelled as ‘Hemiptera’), Eocene Baltic amber originating from Yantarny settlement (formerly Palmnicken), Sambia Peninsula (Figs 5–6). We tentatively identified the specimen as Ripidius cf. primordialis Stein, 1877. Taxonomy. Ripidius primordialis Stein, 1877 was originally described from two specimens housed in two different collections (Stein 1877). The specimen originally described from the Kühl collection is now housed at the MNB and is designated here as lectotype. The lectotype selection is based on the earlier suggestions by Keilbach (1982) and Kaupp et al. (2001), as this syntype was likely used by Stein for the description (see the aforementioned sources for the details), while the second syntype (‘Ein zweiter Stück dieser Art…’ in German (‘The second specimen of this species…’); Stein (1877)) played a secondary role in the original description. Moreover, the second syntype is described as different from the first syntype (designated herein as lectotype) in the colouration. The lectotype designation is therefore made to maintain nomenclature stability. The second syntype therefore becomes a paralectotype with no name-bearing status.
