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 a, 8a), which has a small mushroom-shaped piece in the operculum (Figs. 7 b, 8b); the shape of the sclerites of the endophallus (Figs. 13–16), 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).
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.
