Description. Size. Male. Length of pronotum 1.60–1.79 (mean 1.70) mm, length of tegmina 3.46–4.13 (mean 3.69) mm. (N = 10/10, specimens from Sardinia; specimens from Italy and Sicily slightly smaller). Female. Length of pronotum 1.79–1.92 (mean 1.84) mm, length of tegmina 2.05–2.37 (mean 2.16) mm. (N = 8/5).
Wings. Male. (Fig. 19H,J) Tegmina: Long, almost reaching the end of the abdomen, apex obliquely rounded. Hindwings: Increasing in breadth towards apically, apex with a rather deep median concavity or steplike excision on one side. Female. (Fig. 19I,K) Tegmina: Apical border usually slightly concave, occasionally almost straight. Hindwings: as in male.
Male abdomen. Tergites. Fig. 19A–G. T 6 shows a unique character combination: anterior border mesally strongly produced, transversal ridge present but with a wide median gap, distribution of the large spatular bristles restricted to the posterior half of the tergite surface, laterally with a pair of small deepenings, the anterior one forming a shallow swale (Figs. 1B, 2B, 4A,E, 19C); for more details see under characters of the genus. T7. Pit size: largest with size 2–3 (Fig. 21I). Anterior pit wall (aw) in its structure considerably deviating from the usual composition: the strongly sclerotized area sa —in the other species of the genus forming the uppermost part of the anterior pit wall—is not integrated into the wall, but forms a horizontally mounted sclerite stripe anteriorly adjacent to the pit opening (Fig. 20A,B); posteriorly it bends over in a sharp edge to the rectangularly descending proper pit wall; the latter immediately below the edge often slightly excavated (ec in Fig. 21D); stabilising bracelet s narrow (Fig. 21E,H). Posterior pit wall (pw) with a pair of well developed hemispherical bulges (bu, Figs. 20B, 21C,D). Glandular pouches (gp) very long, surpassing the anterior border of T7 for more than the length of T7 measured at the lateral border, posteriorly ending in a very narrow tailpiece (tp, Fig. 21F); tubules (tu) very long, reaching far beyond the lateral borders of T7 (Fig. 19D), near the tailpieces of the pouches opening into the pit (ot, Fig. 21F). Genital hook with a relatively normally proportioned shaft, the latter below the apical process strongly bulged out (Fig. 19L–N).
Colouration of male tegmina. Lightly coloured stripe between dark stripes unusually narrow (Figs. 19H, 21A).
Distribution. The species is widely distributed on the Italian islands Sardinia and Sicily; from the Italian peninsula it is only known from three localities near the border between Toscana and Latium. The distribution in Algeria seems to be restricted to the most eastern part near the border to Tunesia, with several localities near the Mediterranian coast, in the further surroundings of Annaba, and some localities further inland in the region of Batna. Whether the older report from Saida, far in the West, really concerns this species is doubtful; for this locality L. longitubulata has also to be taken into consideration. The occurrence of the species in California USA, detected by R.Edler, is certainly adventitious.
