Kodaianellissus intorqueus sp. nov.

Diagnosis. This new species is similar to Kodaianella longispina Zhang et Chen, 2010 , but differs by: 1) The widest part in anal tube of male in dorsal view located in apical 1/3, but the latter species in the apex; 2) Periandrium with one pair of processes, but the latter species with two pairs of processes; 3) Capitulum of gonostylus long and slender, but the latter species broad and short.

Description. Length: male (including forewings) (N=13): 6.6–7.1 mm; female (including forewings) (N=8): 6.8–8.3 mm.

Vertex tawny, 2.6 times wider at base than long in midline, with two round brownish markings shaped to circle near base ( Figs. 1, 3 ); anterior margin angularly and slightly convex, posterior margin angularly concave, lateral margins parallel ( Fig. 3 ). Frons tawny, 1.3 times broader at widest part than long in midline, 1.5 times broader at widest part than apical margin ( Fig. 4 ); anterior margin black, lateral margins black but tawny near base, median carina tawny ( Fig. 4 ); frons with one very obvious and broad light yellow M-shaped marking near middle, apical part of frons and lateral area with around 16 light yellow tubercles on each side; the base of frons light yellow ( Fig. 4 ). Postclypeus tawny, middle part yellow with several brownish transverse strips on each side ( Fig. 4 ). Compound eyes grayish brown, supported by tawny callus ( Figs. 1, 3 ). Gena yellowish brown ( Fig. 2 ). Pronotum tawny, 3.1 times wider at base than length in midline; anterior margin sharply convex, carinate, posterior margin brown, median carina yellow, with two small brown incisions on the disc ( Fig. 3 ). Mesonotum light tawny, 2.0 times wider in anterior margin than long in midline; lateral area with two obvious brownish markings respectively near apex and near base on each side, the apical one larger ( Fig. 3 ). Forewings tawny, 2.0 times wider at longest part than widest part, longitudinal veins dark brown and elevated, transverse veins light yellow ( Figs. 1, 5 ). Hind wings brown ( Fig. 6 ). Legs tawny ( Fig. 2 ). The color described above from specimens taking out from alcohol.

Male terminalia. Anal tube in lateral view extremely long and narrow, dorsal and ventral margins parallel from the anal opening, ventral margin prominent ventrally at apex ( Fig. 7 ); in dorsal view long cylindrical, 2.3 times longer in midline than widest part, widest at apical 1/3, apical margin slightly convex at middle in dorsal view ( Fig. 8 ); apical part concave at middle with two lateral angles convex in postero-dorsal view; epiproct short, located at basal 1/3 of anal tube ( Fig. 8 ). Gonostylus triangular in lateral view, widest at middle, posterior margin sloping posterior, caudo-ventral angle rounded; dorso-lateral margin with large triangular process near the base of capitulum ( Figs. 7, 9 ). Capitulum of gonostylus very long and slender, clavate, directed cephalad; apex and posterior margin of capitulum with auricular processes ( Fig. 9 ). Pygofer in lateral view long and slender, anterior and posterior margins parallel, dorsal margin slightly sloping posterior ( Fig. 7 ). Periandrium in lateral view with both sides elevated and twisting at middle, dorso-lateral lobe slightly membranous in the dorso-apical part, convex to a triangular structure directed cephalad, ventral apical part slightly sclerotized on each side with one sharp spine outside directed dorsad ( Fig. 10 ). Ventral periandrium lobe apparently shorter than dorso-lateral lobe, in ventral view apical margin triangularly convex at middle ( Fig. 11 ). Aedeagus with pair of relatively broad hook-like processes near middle directed dorsad ( Fig. 10 ), this pair of processes in ventral view directed outward ( Fig. 11 ). In ventral view periandrium slightly broader in basal part than apical part ( Fig. 11 ).

Female terminalia. Anal tube in dorsal view long cylindrical, 2.4 times broader in midline than widest part, apical margin slightly rounded, lateral margins parallel; anal opening situated at basal 1/4 ( Fig. 12 ). Anterior connective lamina of gonapophysis VIII with three large teeth in apical group, and three keeled teeth in lateral group ( Fig. 18 ). Endogonocoxal process membranous and developed, reaching same level with anterior connective lamina ( Fig. 18 ). Posterior connective lamina of gonapophysis IX in lateral view long and narrow, boat-shaped ( Fig. 16 ), in ventral view triangular, narrowing from base to apical part, apical part concave medially, lateral margins with one triangular process directed outward each side ( Fig. 14 ). Gonoplacs in dorsal view fused near base, widest at base, outer lateral margins oblique ( Fig. 13 ), in lateral view gonoplac subrectangular ( Fig. 15 ). Hind margin of sternite VII slightly concave at middle ( Fig. 17 ).

Etymology. The Latin name “ intorqueus ” means twisted, referring to the twisted special structure on the dorsal margin of periandrium.
