Synanthedon theryi Le Cerf, 1916

( Figs 1–2 , 7–10 )

21 pupal exuviae— 11 males, 10 females ( Spain, Andalusia, Balearic Islands, 1995–2002)

Length and width: 10.9–14.5 x 2.5–3.6 mm (mean: 12.7 x 3.0 mm).

Proboscis almost reaches ends of metathoracic legs ( Fig. 1 ). Area of head projection blade prolonged and 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 few wrinkles ( Fig. 7 ). Plate of head projection blade 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. 8 ). Distance between clypeal setae C1 2 approximately 3.0–3.5 × greater than distance between C1 2 and Cl 1. Labrum truncate for a greater distance and with concave sides. Postclypeus bears small projections ( Fig. 9 ). Cremaster relatively roundly pointed at end and approximately equal in length to anal suture, sometimes anal suture longer than cremaster as in both male and female. Spines on the 10 th abdominal segment robust, triangular, sharply pointed, their setae short ( Fig. 10 ). Spines of basal row on the 2 nd abdominal segment absent. Spines of caudal row approximately 1.5–2.0 × shorter than those of basal row on the 3 rd abdominal segment. Fourth abdominal segment bears 10–13 slender spines of basal row between setae D1. Crevices between them pointed. Ventral edge of subdorsal furrow on mesonotum weak and reaches about barely to 1/3 of dorsal longitudinal ridge length ( Fig. 2 ).

Diagnostic features. Depressions of frons shallow and with a few wrinkles. Ventral edge of subdorsal furrow on mesonotum weak and reaches about barely to 1/3 of dorsal longitudinal ridge length. Fourth abdominal segment bears 10–13 slender spines of basal row between setae D1. Spines of caudal row approximately 1.5–2.0 × shorter than those of basal row on the 3 rd abdominal segment.

Host plants. Tamarix spp. e.g. Tamarix gallica L., T. africana Poiret (Tamaricaceae) ( Laštůvka & Laštůvka 2001).

Distribution. Algeria, Morocco, Spain, Portugal, Mediterranean regions of France, Corsica, Italy, Slovenia ( Špatenka et al. 1999; Laštůvka & Laštůvka 2001; Predovnik 2017).
