Diagnosis. Length = 6.5–8.5 mm (n = 170). Among the taxa belonging to the L. tristigma species group, L. tristigma can be separated by the small size of the median lobe of aedeagus (2.9–3.4 mm, n = 32) ( Figs. 7 View FIGURES 1 – 8 a, 8a), which has a small mushroom-shaped piece in the operculum ( Figs. 7 View FIGURES 1 – 8 b, 8b); the shape of the sclerites of the endophallus ( Figs. 13–16 View FIGURES 9 – 16 ), with two lateral pieces short, not enlarged apically and markedly bent medially (thus converging apically), and the unpaired central sclerite clearly broader than long and wider apically than basally; and spermathecal duct comparatively short and curled in numerous small loops ( Figs. 22–23 View FIGURES 17 – 23 ).

Distribution. Lachnaia tristigma is widely distributed in the Iberian peninsula, excluding only the areas occupied by L. gallaeca and L. pseudobarathraea , and southern France, whereas records from Italy and northern Africa are doubtful ( Regalin, 2004). In the latter region, this species was not recorded from Morocco by Codina Padilla (1958) and we also failed to find any Moroccan specimen in MNCN collection.
