Genus Symplana Kirby, 1891

Symplana Kirby, 1891: 136 . Type species: Symplana viridinervis Kirby, 1891 , by monotypy.

Diagnosis. Head elongate, with bendable apical part ( Figs 15 , 41 ). Metope long and narrow, slightly narrowing above the eyes, with distinct medi­ an carina running from its upper margin throughout postclypeus and sublateral carinae running from its upper margin, but not reaching metopoclypeal suture, which is convex ( Figs 3 , 8 , 14 , 17 , 38 , 40 , 52 ). Coryphe with rounded apex and acutely angulate posterior margin. Apical part of coryphe (above bend line) as long as its basal part (below bend line) ( Figs 39, 41 , bl) or nearly twice longer ( Figs 15, 16 , bl). Ocelli present. Pedicel elongately cylindrical, without apical projection. Rostrum reaching hind coxae, with cylindrical, not narrowing apically, 3rd segment, 0.5 as long as 2nd one. Pronotum with wide paradiscal fields and paranotal lobes. Each paranotal lobe with a strong carina behind the eye ( Fig. 15 ). Anterior margin of pronotum sharply convex, with rounded apex, posterior margin widely concave. Tegulae large. Forewings semitransparent (matte), with narrowly oval or elongately triangular basal cell, distinct nodal line and nearly straight or weakly concave costal margin. Forewings long and narrow, 6–7 times as long as wide medially, narrowing apically after the nodal line, with narrow membrane ( Figs 18 , 42 , 62, 63 ); clavus long, four times as long as whole wing; R and M with short common stem. Forewing vein sequence: R 3, furcating before nodal line, with the anterior branch (R 1) furcating shortly and only posterior branch (R 2) running after the nodal line; r–m 1; M 3–8, furcating after the nodal line; m–cua 1; CuA 1–3, furcating after the nodal line ( Figs 18 , 42 , 62 ). Hind wings well developed, 3­lobed, with very weak cubital cleft and deep vannal cleft; anal lobe wide. Hind wing vein sequence: R 2, shortly furcating apically; M 2–3; CuA 2; CuP 1; Pcu 1; A 1 1; A 2 1. A 2 not reaching wing margin. Hind tibia with a single lateral spine above its middle. First metatarsomere as long as second and third ones combined; first and second metatarsomeres without spines. Ventral surface of first metatarsomere with short thick setae. Aedeagus often with rows of denticles dorso­laterally. Gonopore subapical, in shape of long trough ventrally ( Figs 22, 23 ). Connective fused with an aedegal basement ( Fig. 68 ). Phallobase reduced. Styles attached behind the aedeagal shaft. Style with capitulum and sometimes with additional process. Gonoplacs shortly triangular (in lateral view) ( Fig. 28 ). Endogonocoxal lobes (GxL) of gonocoxae VIII fused in a large single lobe ( Figs 30, 32–35 ).

Composition. Eight species are distributed from Ceylon and southern India to Sumatra, Vietnam, and China.
