Diagnosis. From L. cyprica and L. beybienkoi distinguished mainly by two characters: the edge, a lateral continuation of the anterior border of the pit openening (ed in Fig. 33H–J View FIGURE 33 ), and the massive and more or less club-shaped glandular tubules (tu in Figs. 31D View FIGURE 31 , 32C View FIGURE 32 , 33I,J View FIGURE 33 ).

Etymology. The species name refers to the hitherto known distribution of the species restricted to the country Greece (Crete and continental Greece).

Description. Size. Male. Crete: Length of pronotum 1.86–2.05 (mean 1.95) mm, length of tegmina 4.54–5.44 (mean 4.94) mm. (N = 12/12). Female. Crete and Greece: Length of pronotum (mean) 1.98 mm, length of tegmina (mean) 2.37 mm. (N = 3/10). T6: Distance between the anterior bristle stripes as % of tergite breadth: range 14.6– 24.7, mean 19.8. (N = 9).

Female tegmina. Apical border shallowly concave ( Figs. 31H View FIGURE 31 , 32B View FIGURE 32 ).

Male abdomen. Tergites. Fig. 31A–F. T View FIGURE 31 6 View FIGURE 6 . Highly specialised as described under characters of the genus and the beybienkoi -group; in the main structures not differing from the other species of the group ( Fig. 6D View FIGURE 6 ). Two alleged specialties visible in this figure, a membraneous transversal fold (fo) and a w-shaped dark line between the anterior bristle stripes (arrowhead) are occasionally also found in other species of the beybienkoi- group. The comparison with the other species ( Figs. 1D View FIGURE 1 , 6B,C View FIGURE 6 ) shows, however, that there are differences in the distance between the anterior bristle stripes; the distance is smallest in L. graeca (mean: 19.8% of the breadth of the tergite; L. beybienkoi 22.3%, L. quadrivittata 23.4 %, L. cyprica 25.7%). But since there is considerable overlap between the species (see corresponding values for each species under “ Size ”) these differences are of little value for species separation. T7. Pit. Anterior border (ab) of the pit opening laterally continuing into an narrow fold or edge (ed) converging with the gutter (gu) and approaching it closely near the lateral border of the tergite ( Figs. 31D View FIGURE 31 , 33H–J View FIGURE 33 ); pit size: up to size 5 ( Fig. 31D View FIGURE 31 ); anterior pit wall (aw) with transparent windows (w), stabilising bracelet (s), window frame (wf), and transversal folds (tf, Fig. 32C–G View FIGURE 32 ); posterior pit wall (pw) with a pair of bulges (bu), either shallowly bowlshaped ( Fig. 32F View FIGURE 32 ), or, more often, with a strange rectangular appearance ( Fig. 33H–J View FIGURE 33 ). Glandular pouches (gp) long, tubules (tu), short, more or less club-shaped, rather massive, in nearly every preparation well visible ( Figs. 31D View FIGURE 31 , 33J View FIGURE 33 ). Genital hook. Claw (cl) as in L. cyprica with a large crest (cr) having two antlerlike processes (an, Fig. 31K,L View FIGURE 31 ).

Distribution. Crete and Nom. Chalchidiki and Aetolia-Akarnia of continental Greece

IV. Doubtful species

The fourth group of species assembles two possible new species, which due to the incompleteness of the knowledge of their characters cannot yet be established as new species.
