Synanthedon codeti ( Oberthür, 1881)

( Figs 3–6 )

22 pupal exuviae— 10 males, 12 females ( France, Spain, 1993–1999)

Length and width: 9.8–13.2 × 2.2–2.8 mm (average: 11.5 × 2.4 mm).

Proboscis almost reaches ends of metathoracic legs. Blade of head projection variable in shape, widely rounded, sometimes widely truncate at the end, but lacking two points. Frontal setae situated approximately at level of lateral angles of frons in dorsal view. Depressions of frons shallow and with a few wrinkles, frons central ridge strong ( Fig. 3 ). Plate of head projection blade relatively short, not curved in lateral view. Dark margin narrow. Frons rises gently from its projection blade in lateral view. Lateral depression on head relatively narrow, elongated and caudoventrally concave ( Fig. 4 ). Distance between clypeal setae C1 2 approximately 2.5–3.0 × greater than distance between C1 2 and Cl 1. Labrum truncate for a greater distance and with straight sides. Postclypeus bears small projections ( Fig. 5 ). Cremaster short and pointed, anal suture longer than cremaster in both male and female. Spines on the 10 th abdominal segment robust, triangular, sharply pointed, their setae short ( Fig. 6 ). Spines of basal row on the 2 nd abdominal segment absent or tiny and without distinguishable points. Spines of caudal row approximately 2.5–3.0 × shorter than those of basal row on the 3 rd abdominal segment. Fourth abdominal segment bears 6–7 slender spines of basal row between setae D1. Crevices between them wider, bow-like.

Diagnostic features. Depressions of frons shallow and with few wrinkles. Ventral edge of subdorsal furrow on mesonotum weak and reaches about barely to 1/4 of dorsal longitudinal ridge length. Fourth abdominal segment bears 6–7 slender spines of basal row between setae D1. Spines of caudal row approximately 2.5–3.0 × shorter than those of basal row on the 3 rd abdominal segment.

Host plants. Querqus spp., ( Fagaceae ), Corylus avellana L. ( Betulaceae ), Platanus orientalis L. ( Platanaceae ), Carya illinoinensis (Wangenh.) K.Koch (Junglandaceae) , Malus spp. , Prunus spp. (Rosaceae) ( Laštůvka & Laštůvka 2001).

Distribution. Morrocco, northern Algeria; Tunisia, Portugal, Spain, France-eastern Pyrennes, Italy – Sardinia ( Špatenka et al. 1999; Laštůvka & Laštůvka 2001).
