description: Ricanula peronata sp. nov.   
(Figs 7–9, 11)  
 Etymology. The name is derived from the Latin word ‘ peronatus ’, referring to the periandrium with boot-shaped ventral processes in ventral view.   
 Diagnosis. The species is similar to Ricanula curva sp. nov., but differs from the latter by having periandrium with boot-shaped ventral processes in ventral view (Fig. 9F); ventral processes of aedeagus oriented ventrally in lateral view (Fig. 9G) (apical part of ventral processes of periandrium strongly curved laterally in dorsal and ventral view; ventral processes of aedeagus S-curved in lateral view in Ricanula curva sp. nov.).   
 Description. Measurements. Length (inc. tegmen): male 6.5–7.4 mm, female 7.3–8.8 mm.   
 Head. Vertex (Figs 7A, C) without median carina. Frons: median and lateral carinae of frontal disc surpassing half of disc, ending about the level of antennae; apical parts of median carina weakly visible.   
 Thorax. Pronotum (Figs 7A, C) with small round depressions submedially on each lateral side. Mesonotum: lateral carinae (Figs 7A, C) not reaching posterior margin; antero-lateral carinae not connected with anterior margin.   
 Tegmen: postero-apical part of tegmen with two eye-spot black cells, posterior margin arcuate. Longitudinal veins ScP+RA and RP, MP arising as short common stem from basal cell. Claval veins Pcu and A 1 fused on midlength of CuP vein. Hind wing (Fig. 7F) without transverse veinlets.   
Hing legs: Basitarsomere of metatarsus with 8 apical teeth. Metatibiotarsal formula 2/6/8.  
 Male terminalia. Anal tube (in dorsal view, Fig. 8B) nearly square, posterior margin strongly concave, basal margin slightly convex, lateral margins straight; anus placed before midlength, paraproct surpassing the posterior margin. Pygofer (in lateral view, Fig. 8A) with dorsal posterior angle without process. Genital styles (in lateral view, Fig. 8A) broadly triangular; ventral margin weakly sinuate; dorsal margin weakly convex, with small concavity before spine-like process.   
Phallic complex (Figs 9A–C): Periandrium (Figs 9D–F) with boot-shaped ventral processes in ventral view, apical part of ventral processes straight; dorsal periandrium with U-shaped structure with membranous apical part sclerotized base in dorsal view; lateral margin of periandrium with small rod-shaped processes in lateral view, rodshaped processes hidden in the periandrium (in ventral view); ventral periandrium distinctly convex.  
Aedeagus (Figs 9G–I) apically with two pairs of processes. Median split asymmetrical: ventral split present only in 1/5; dorsal split very deep, reaching almost basal part. All processes single armed: lateral processes longer than ventral processes, about two thirds of aedeagus; ventral processes oriented ventrally in lateral view.  
 Female terminalia (Figs 8C–I). Pregenital sternite (Fig. 8I): posterior margin medially with two prominent processes, margin between processes with wide and shallow incision.   
Anal tube (in dorsal view, Fig. 8C) ovoid, with widest part medially, basal margin weakly convex, posterior margin widely concave, lateral margins arcuate; anus placed after midlength, paraproct surpassing the posterior margin.  
Gonoplac (Fig. 8H): posterior margin with two rows of small teeth.  
  Coloration.  General color brown (Figs 7A–B). Median part of frons (Fig. 7D) black brown. Eyes brown (Figs 7B–C), ornamented with irregular brown patches. Gena (Fig. 7B) black brown with two yellowish spots. Tegmen (Figs 7B, E) brown, costal margin with about 14 transverse black brown stripes from base to a little beyond middle, between the transverse brown stripes filled with light yellow stripes, sub-medially of tegmen with a large flavescent spot marked by 2 central transverse back lines. Wings brown, each side of A 2 with a longitudinal grayish narrowed band (Fig. 7F). Abdomen and terminalia brown.
