Phyllodromica quadrivittata Chopard, 1963: 164, fig. 1; Princis 1971, 1097.
Diagnosis. In the male sex characterised by the hook having an abnormally broadened shaft as is typical for the beybienkoi -group, but with the claw still resembling the species of the longitubulata - and trivittata -group by having a small triangular crest, and no antlerlike processes (Fig. 23J,K).

(M. Tel Aviv).
Additional, already published reports. ISRAEL: Kirjath-Anavim (Bodenheimer 1935), determined as L. trivittata, according to the locality presumably L. quadrivittata (Isr 15); Ein Gedi (Isr 2) (Chopard 1963).
Description. Size. Male. Length of pronotum 1.57–1.82 (mean 1.70) mm, of tegmina 3.81–4.45 (mean 4.03) mm. (N = 7/7). Female. Length of pronotum 1.73–1.86 (mean 1.80) mm, of tegmina 1.76–2.11 (mean 1.99) mm. (N = 8/8). T6 of male: Distance between the anterior bristle stripes in % of the tergite breadth: range 21.4–24.3, mean 23.4. (N = 7).
Female tegmina. Apical border shallowly concave (Figs. 23G, 24G).
Male abdomen. Tergites: Fig. 23A–E. T 6. Highly specialised as described under characters of the genus and the beybienkoi -group (Figs. 1D, 2D, 3B, 4D,G, 5A). T7. Pit opening with gutters (gu, Figs. 23C, 24A, 33A) reaching near to the lateral borders of the tergite; pit size up to size 4; a nterior pit wall (aw) as in all other species of the group without strongly sclerotized area (“sa” in Fig. 24A), stabilising bracelet (s) narrow, window frame with well developed transversal folds (tf, Fig. 24B,C); posterior pit wall (pw) with a pair of wide and shallow bulges (bu, Fig. 24A,C); glandular pouches long (gp, Figs. 23C, 24A), tubules short (tu, Fig. 23C). Genital hook. Among the species of the beybienkoi -group with the broadest shaft (sh), but shape due to largely membraneous parts difficult to define, apical process (ap) restricted to the right half of the upper end of the shaft (Fig. 23D), forming a triangular peak; claw (cl) from the base almost rectangularly bent, crest (cr) small, rounded triangular, without antler processes (Figs. 23J,K, 24D,E).
Distribution. The distribution is—as far as known—restricted to a rather narrow zone in central Israel, mainly west of Jerusalem at a latitude between 31° 30’ and 32° 00’ N (Fig. 41) but may reach further to the South: Chopard (1963) is presumably right in assigning a larva from Ein Gedi to this species (Isr 2). Whether the two larvae from Tel Aviv (Isr 7) and the Tel Baruch Beach (Isr 5)—both localities situated slightly north of 32°00’—also belong to this species cannot be decided now.
