LAESTRIS Melsheimer (1806, p. 59, nomen nudum) 1844, p. 40. [Synonym of 

 Stenus.} 

 Qenotype: Laestris fuscipes (Melsheimer) {Stenus). 

 Fixed ly : Melsheimer, 1844, p. 40, by monotypy. 



Discussion : In 1806 this was listed in the Melsheimer Catalogue with three 

 trivial names. Two of the trivial names were without authority and 

 apparently cannot be identified from this work. The third, fuscipes, was 

 credited to "K." who is undoubtedly Knoch (manuscript). In 1844 "Laes- 

 tris fuscipes, Melsh. Catal. 1345," was listed as a synonym of Stenus 

 erythropus n.sp. This would appear to validate fuscipes as a synonym of 

 erythropus and therefore to place one valid specific name under Laestris, 

 validating it monobasically. 

 Synonyms: (See Stenus). 

 LAMECHUSA [Error for Lomechusa']. 

 LAMIOTA Casey, 1910a, p. 17. [Synonym of Liogluta.] 

 Genotype: Lamiota keeni (Casey) (Atheta).

 LAMPRINODES Luze, 1901, p. 181. 



Genotype: Lamprinodcs saglnatus (Gravenhorst) (Tachyporus). 

 Fixed hy : Lucas, 1920, p. 360, by subsequent designation. 

 Later citations: L. saginatus (Gravenhorst), by Tottenham, 1939b, p. 229; 

 1949b, p. 380. 

 LAMPRINUS Heer, 1839, p. 286. 



Genotype : Lamprinus lasserrei Heer . 

 Fixed ly : Heer, 18.39, p. 286, by monotypy. 



Later citations : L. lasserrei Heer, by Jacquelin du Val, 1857, p. 24, as 

 synonym of erythropterus (Panzer). L. nigricornis (Gyllenhal), by 

 Thomson, 1859, p. 46, not originally included. L. erythropterus (Panzer), 

 by Lucas, 1920, p. 360, not originally included. L. lasserrei Heer, by 

 Tottenham, 1949b, p. 380. 

 Discussion : The designation of erythropterus can be accepted only through 



the subjective synonymy of erythropterus and lasserrei.

 former isogenotypic) by Blackwelder (1943).
