Body elongate-oval, color black, completely covered with metallic greenish scales ( Fig. 2 View FIGURE 2 a–d), head oval, densely covered with scales, frons depressed, with a longitudinal sulcus ( Fig. 2 View FIGURE 2 c, e), eyes oval, large, distinctly convex, inferior margin narrower than dorsal one ( Fig. 2 View FIGURE 2 a, h), tibiae and tarsi dark ferrugineous ( Fig. 2 View FIGURE 2 ı, i).

Rostrum ( Fig. 2 View FIGURE 2 e, 3a) elongate, length of rostrum more than twice width, with deep median longitudinal sulcus and one adjacent keel on each side, densely covered with scales and setae.

Antenna ( Fig. 2 View FIGURE 2 f) black, covered with yellowish hairs, scape long, basally curved, gradually widened from base to apex, reaching margin of eyes, first segment of funicule slightly longer than second, I and II segments longer than others.

Prothorax ( Fig. 2 View FIGURE 2 g, 3b) in dorsal view slightly transverse, hind margin wider than front margin, sides rounded, widest at middle, disc of pronotum with dense shiny scales and short suberect setae, postocular lobes weakly developed ( Fig. 2 View FIGURE 2 h).

Elytra ( Fig. 2 View FIGURE 2 a–d) elongate-oval, striae formed by row of separate punctures, interstria flat, wide on disc, erect setae in three or four irregular rows, apical part of setae bifurcate ( Fig. 3 View FIGURE 3 c–d).

Legs long and thin, femora black, untoothed, tibiae and tarsi dark ferrugineous, fore tibiae slightly incurved at apex in male ( Fig. 2 View FIGURE 2 ı), straight in female ( Fig. 2 View FIGURE 2 i), internal denticulation absent, claws free.

Male genitalia. Aedeagus in lateral view distinctly curved, median lobe straight in middle, narrowed towards apex, in dorsal view elongate, nearly parallel-sided, narrowed to apex, ostium distinct, rounded, apex with sclerotised line ( Fig. 4 View FIGURE 4 a–b), tegmen ring like, basally located, parameres dorsal, manubrium long and thin ( Fig. 4 View FIGURE 4 c), sternite 9 (spiculum gastrale) thin, curved behind middle, connected to two symmetrical plates ( Fig. 4 View FIGURE 4 d).

Female genitalia. Spermatheca hook-like, cornu short, folded basally, basal part of spermatheca wide, well sclerotised, ramus long and with two lobes (giving it a segmented appearance), nodule short and narrowed ( Fig. 4 View FIGURE 4 e), ovipositor long, stylus short and cylindrical, color dark, bearing 3–4 short erect setae at apex ( Fig. 4 View FIGURE 4 f), spiculum long, rod-like, abdominal sternum 8 V-shaped ( Fig. 4 View FIGURE 4 g).

Diagnosis and discussion. Aspidiotes candani sp. nov. is related to A. anatolicus ( Colonnelli, 1978) . The new species differs primarily from A. anatolicus in eye shape, form of pronotum, form of setae on disc of elytra, surface morphology of scales, structure of aedeagus (in dorsal view) and form of spermatheca. In A. candani the eyes are elongate-oval ( Fig. 2 View FIGURE 2 a, h), the apical margin of the pronotum is straight ( Fig. 2 View FIGURE 2 g, 3b), the setae on the disc of elytra are erect and apically bifurcate ( Fig. 3 View FIGURE 3 c–d), the surface of the scales has large, distinct granules ( Fig. 3 View FIGURE 3 e–f), aedeagus (in dorsal view) has an apical sclerotised line and the ostium is oval ( Fig. 4 View FIGURE 4 b), the spermathecal cornu is short and folded basally, ramus has two lobes that look like segments ( Fig. 4 View FIGURE 4 e). In A. anatolicus (according to Sanchez-Ruiz and Alonso-Zarazaga, 1994), the eyes are round, the apical margin of the pronotum is oval, the setae on disc of elytra are suberect, curved basally, simple apically, aedeagus (in dorsal view) lacks a sclerotised line, the ostium is indented and “w” shaped, spermathecal cornu is long and not folded, the ramus is simple. According to Sanchez-Ruiz and Alonso-Zarazaga (1994), Aspidiotes Schoenherr, 1847 includes two subgenera ( Phaenognathus Schoenherr and Aspidiotes Schoenherr ). The subgenus Phaenognathus Schoenherr is recognized by the aedeagus with flagellum long and slender, spermatheca with long ramus. It contains the Eastern Mediterranean species A. anatolicus and A. thalassinus . The subgenus Aspidiotes Schoenherr is recognized by the aedeagus with flagellum short, robust, and spermatheca with short ramus. It includes the Western Mediterranean species A. cottyi , A. larbii , A. gonzalezi and A. westringii . Aspidiotes candani should be considered within the A. (Phaenognathus) anatolicus group due to its long aedeagal flagellum, and spermatheca with long ramus.
