Supplementary description

Coryphe transverse (three times as wide as long), anterior margin convex with truncated apex, posterior margin concave. Metope convex (visible from above), with weak longitudinal keels joined at its upper margin. Pronotum with weak median keel. Scutellum without keels. Forewing weakly narrowing apically, with narrow hypocostal plate. Radius bifurcate, median trifurcate, cubitus anterior simple ( R 2 M 3 CuA 1). Metatarsomere I with 2 intermediate spines.

Coloration ( Figures 8 and 9 ). General coloration light yellowish brown. Traces of sensory pits of metope brown. Upper margin of postclypeus dark brown. Femora and tibiae with brown longitudinal stripes. Apices of spines of legs dark brown. Abdominal sternites light yellow; sternites IV and V with dark brown median areas; traces of sensory pits dark brown. Abdominal tergites I–VI dark brown with light yellow median line, tergites VII–VIII light yellow. Gonoplacs dark brown with light yellow lateral areas. Female anal tube light yellow with brownish apex.

Male genitalia ( Figure 30 ). Pygofer with convex hind margin in apical part. Anal tube elongate, narrowing apically (in dorsal view), its lateral margins turned down, straight in lateral view. Anal column one-third as long as anal tube. Each dorsolateral phallobase lobe with wide horizontal supporting process situated near to its ventral margin and narrow covering process. Ventral phallobase lobe long. Aedeagal hooks directed to dorsal side of the phallobase. Style with weakly concave hind margin; caudodorsal angle widely rounded. Capitulum of style weakly narrowing to rounded apex (in dorsal view); lateral tooth with deeply concave margin.

Female genitalia. Hind margin of sternum VII with short and broad semicircular median process. Anal tube nearly rectangular, weakly narrowing apically (in dorsal view), convex (in lateral view). Anal column about one-quarter as long as anal tube. Gonocoxa VIII with lobe-shaped hind margin bearing leaf-like process distally.

Body length. Males 3.4–3.9 mm; females 3.7–4.3 mm.

Distribution

The species is known from Tunisia and Sicily ( Ferrari 1884; present data).

Note

The species was described after a female from Tunisia ( Ferrari 1884). We have based our treatment of the species on male specimens from Tunisia.
