Supplementary description Metope with weak median and sublateral keels joined at its apical margin. Coryphe 2.5–3.0 times as wide as long, its margins keel-shaped. Pronotum with weak median keel. Scutellum with weak lateral keels. Forewing, narrowing apically, with narrow hypocostal plate. Radius bi- or trifurcate, median trifurcate, cubitus anterior simple ( R 2–3 M 3 CuA 1). Metatarsomere I with two intermediate spines. Coloration ( Figures 10, 11 ) . General coloration light brown yellowish. Metope with many dark brown dots, traces of sensory pits also dark brown. Clypeus with dark brown stripes and spots. Pronotum sometimes with dark brown traces of sensory pits. Femora and tibiae with dark brown longitudinal stripes, dorsal margins of hind femora dark brown. Abdominal tergites dark brown. Abdominal sternites yellowish with dark brown anterior margin, middle part, and spots around the setae. Genital segments yellowish. Apices of metatarsomeres III, claws, teeth, and spines of legs dark brown. Male genitalia ( Figure 31 ) . Pygofer with weakly convex apically hind margin. Anal tube narrowing apically, its lateral margins turned down. Anal column about onethird as long as anal tube. Phallobase with waist proximally. Each dorsolateral phallobase lobe with rudimentary supporting process and narrow covering process. Ventral phallobase lobe long, narrowing apically, with a pair of longitudinal bulging projections basally which cover supporting processes of the phallobase (in ventral view). Hind margin of style weakly concave; caudodorsal angle widely rounded. Capitulum of style narrowing to rounded apex (in dorsal view); lateral tooth with concave margin. Female genitalia . Hind margin of sternum VII with short and broad median process. Anal tube convex (in lateral view). Each distal part of posterior connective lamina of gonapophyses IX with short tooth in bend place. Gonocoxa VIII with high lobeshaped hind margin bearing leaf-like process distally. Body length . Males 3.8–4.1 mm ; females 4.0– 4.3 mm . Distribution Authentically known from Algeria ( Rey 1891 ; present data). Note The species was described from Teniet el Haad ( Rey 1891 ) and we base our treatment on the topotypes. Type specimen was not examined. Falcidius diphtheriopsis Bergevin, 1919 ( Figures 12–14 , and 32) Falcidius diphtheriopsis Bergevin 1919: 157 .

Supplementary description Metope with weak median keel and traces of sublateral keels. Coryphe 2.5–3.0 times as wide as long. The border between metope and coryphe keel-shaped. Pronotum and scutellum without keels. Forewing with broad hypocostal plate. Radius and median bifurcate, cubitus anterior simple ( R 2 M 2 CuA 1); net of transverse veins.

Pygofer with weakly convex medially hind margin. Anal tube strongly enlarges medially and narrowing basally (in dorsal view), with rounded apex, its lateral margins turned down (in lateral view). Anal column one-third as long as anal tube. Each dorsolateral phallobase lobe with reduced supporting process and wide covering process. Aedeagal hooks curved at right angle. Style with strongly concave hind margin; caudodorsal angle widely rounded. Capitulum of style long, weakly narrowing to truncated apex (in dorsal view). Female genitalia . Sternum VII with weakly convex hind margin. Anal tube elongate, rounded, weakly narrowing apically. Gonoplacs with deep incision between first and second lobes.
