Staphylinidae Paederinae of the genus Lathrobium , but also reported on Philonthus ( Balazuc 1990 ) . Recorded from USA ( type ), Poland , United Kingdom , France , Spain ( Majewski 2008 ), and Sweden ( Huggert 2010 ). Collections examined from Denmark On Tetartopeus terminatus (Gravenhorst, 1802) (Col. Staphylinidae Paederinae ) DENMARK – Nordøstsjaelland (NEZ) • Sortemose ; 55°48.061′ N , 12°20.120′ E ; UB38; 16 Feb. 1949 ; A. West Dry0119 ; A. West det.; ZMUC C-F-124186 . Remarks First record from Denmark . The Danish material consists of a single thallus, which was found among thalli of the common Rhadinomyces pallidus . As the Danish thallus is not in great condition, we include an image of a thallus from Spain ( Fig. 55D ) from material published in Santamaria (1995b) , for comparison.
