Jelínek, Josef & Audisio, Paolo, 2009, The Kateretidae, Nitidulidae and Monotomidae (Coleoptera: Cucujoidea) described by Gistel (1856, 1857): new synonymies and type designations, Acta Entomologica Musei Nationalis Pragae 49 (1), pp. 225-238 : 229-230

Theridiosmum Gistel, 1856

Theridiosmum Gistel, 1856: 36 . Type species: Silpha bipustulata Linnaeus, 1761 [= Nitidula bipunctata ( Linnaeus, 1758) ], by subsequent designation here.

Four of the five species originally included in the genus belong to Nitidula Fabricius,

1775:

Theridiosmum bipustulatum [sine auct.] [= Silpha bipustulata Linnaeus, 1761 = Nitidula bipunctata ( Linnaeus, 1758) ];

Theridiosmum sordidum [sine auct.] [= Nitidula sordida Fabricius, 1792 = Omosita colon ( Linnaeus, 1758) ];

Theridiosmum rufipes Lin. [= Silpha rufipes Linnaeus, 1767 = Nitidula rufipes (Linnaeus, 1767) ];

Theridiosmum quadripustulatum [sine auct.] [= Nitidula quadripustulata Fabricius, 1792 = Nitidula carnaria (Schaller, 1783) ];

Theridiosmum flexuosum [sine auct.] [= Nitidula flexuosa Olivier, 1790 = Nitidula flavomaculata Rossi, 1790 ].

We designate Silpha bipustulata Linnaeus, 1761 as the type species for the genus. Theridiosmum Gistel, 1856 is thus an objective junior synonym of Nitidula Fabricius, 1775 , listed as synonymous by GISTEL (1856: 401).
