Pterilia signata Distant

(fig. 25)

Supplementary description. Metope elongate, lateral margins weakly convex, apical angles horn-shaped. Metope with median and sublateral keels reaching its apical margin, but not joined apically and not reaching clypeus. Median keel of metope reaching only middle of metope. Clypeus wide and long. Coryphe transverse, anterior margin strongly convex and truncate, posterior margin obtusely angulate. Pronotum pressed-in, with anterior margin strongly convex, posterior margin straight. Scutellum longer than pronotum, without keels. Fore wings narrow apically, with transparent precostal area. Corium is not transparent. Radius and median bifurcate, cubitus anterior simple, veins with several callosities. Clavus long (3/4 as long as corium). Hind wings well developed, with deep incision between remigium and vannus. Radius, median, cubitus anterior, cubitus posterior, and first anal vein simple, postcubitus bifurcate, veins with numerous branches apically, anal lobe narrow. Hind tibia with 2 lateral teeth. Metatarsomere I with 6 intermediate socle setae.

Male genitalia (fig. 25). Pygofer with convex hind margin. Anal tube wide, flat, with notch apically. Phallobase flattened dorso-ventrally. Dorso-lateral phallobase lobes not fused apically. Each dorso-lateral phallobase lobe narrows apically, with lobe-shaped projection under aedeagal ventral hooks (in lateral view). Ventral phallobase lobe reaching apices of dorso-lateral lobes, broad, widely rounded apically with notch. Aedeagus with a pair of long ventral hooks. Apical aedegal processes long, protruding above apical margin of phallobase, narrow apically. Suspensorium well sclerotized. Style with convex hind margin, caudo-dorsal angle narrowly rounded. Capitulum of style flattened laterally, on short neck, with large lateral tooth situated perpendicular to capitulum.
