SYNTYPES : 6 (field no. missing [5.09, 5.11, 5.12]; 1245 [5.10]; 482 [5.13]), Picea abies . Schizoneura costata ( Hartig, 1839 ) (change of combination— Hartig, 1841: 367 ). Cinara costata ( Zetterstedt, 1828 ) (senior secondary homonym and synonym—Börner, 1952: 45, “ Lachnus costata (Zett. 1828) Wahlgr, 1939 ”). Valid Specimens. Six on five pins following the Schizoneura costata ( Hartig, 1839 ) label, all in poor condition. All but one (1245) are apterae. Four are mounted on three points; one of these with a needle from its host plant also on the pin. Specimen 1245 collected from “Abiet” by Wilhelm Saxesen in 1839 and pinned. Specimen 482 collected alive from pine needles in Tiergarten , Berlin on June 7, 1833 and then pinned with host tissue . Remarks. Hartig (1841) identified Picea abies as the host, but an unlabelled in situ specimen in this series appears to be from a different host species. Hartig placed this species within the genus Lachnus in Hartig (1839) and then transferred it to the genus Schizoneura ( Hartig 1841 ) on the basis of the shape of the wing and radial cell. Confirmation of the current synonymy with Cinara costata ( Zetterstedt, 1828 ) , recognized first by Börner (1952), is needed.
