Among the taxa belonging to the L. tristigma species group, L. pseudobarathraea can be separated by the large size of the median lobe of aedeagus (3.3-4.0 mm, n = 24) ( Figs. 3 a, 4a, 5a, 6a), which has a mushroom-shaped piece in the operculum much wider than the lateral arms ( Figs. 3 b, 4b, 5b, 6b); the shape of the sclerites of the endophallus ( Figs. 10-12 ), with two lateral pieces long but not enlarged apically and the unpaired central sclerite approximately near as long as broad and near as wide apically as basally; and spermathecal duct extraordinarily long and generally not curled in small loops ( Figs. 18, 19, 21 , but see Fig. 20 ).

Lachnaia pseudobarathraea is distributed in southern Spain , from the Betic mountain ranges to the south and ranging from eastern Malaga to south Alicante. Remarks. Specimens from the cited distribution range but not from the type locality (Sierra Nevada) were identified as L. tristigma by previous authors based on the small elytral dots. We studied the Codina Padilla collection (now deposited in MNCN) and confirmed that specimens (two females) he recorded from Jaén (Sierra de Cazorla) and attributed to L. tristigma ( Codina Padilla, 1958 ) are in fact L. pseudobarathraea , based on their spermathecae. This seems also the case of specimens from Almería attributed to L. tristigma by Cobos (1954) , based on the median lobe of aedeagus figured by the cited author, and Petitpierre (2000) .
