Acupalpus luridus Dejean, 1829: 454 .

The specimen here designated as lectotype is a female bearing labels “ luridus m. in Hispania” and “ Lectotype of Acupalpus luridus Dejean, 1829 desig. by J. Serrano ” .

The name is currently considered a synonym of Acupalpus flavicollis (Sturm, 1825) (see Jaeger, 1989). As in the case of Acupalpus atratus, the specimen of A. luridus of Dejean had been already validly published by Sturm in 1825. It is strange that Dejean did not notice Sturm’s work, as Dejean himself mentioned that he worked with the type material sent by Sturm. Jaeger (1988) discussed the nomenclatural problems involving A. dubius, A. flavicollis and other taxa of Acupalpus, either with or without a dorsal pore in the second half of the third interval of elytron.

Acupalpus flavicollis Sturm, 1825 is found in Europe, to the east it reaches Kazakhstan and Turkmenistan
