Diagnosis. Posterior margin of pronotum and tegula pale yellow ( Figs 16A, D View FIGURE 16 ). Median longitudinal carina of pronotum weakly marked ( Fig. 16D View FIGURE 16 ). Forewing light brown with whitish regions. Ventral margin of periandrium with short indentation ( Fig. 17G View FIGURE 17 ). Gonapophysis VIII (first valvula) with four projections on lateromedian margin and dorsal margin with irregular teeth ( Fig. 18E View FIGURE 18 ).

Redescription (male and female). Measurements. Body length: male 3.1 – 4.1 mm (6.4 – 6.5 including wing) (N=2); female 3.3–4.8 mm (6.0 – 6.6 mm including wings) (N=2).

Coloration. General body color light brown ( Figs 16A, B View FIGURE 16 ). Upper half of frons, pedicel plate organs, median region of pronotum, lateral and posterior margin of pronotum and tegula pale yellow ( Figs 16C, D View FIGURE 16 ). Forewing semihyaline, dark brown with whitish regions and light yellow veins: wide, whitish diffuse spot in the basal region extending from the median region of the postcostal cell up to the CuP vein; long, wide, white diffuse band in the middle region extending from apical region of the postcostal cell to CuA 1 vein; long, wide, white diffuse band on apical region extending from apex RA vein up to the CuA 2 vein; narrow white stripe on apical region extending from to the MP1 vein up to the anterior cubital area ( Fig. 40 C View FIGURE 40 ). Hind wing semihyaline, light brown with hyaline regions ( Fig. 40D View FIGURE 40 ). Legs light brown. Abdomen light brown, except upper half of sternite III yellow brown ( Fig. 16E View FIGURE 16 ).

Head: frons narrow, distance between the lateral carinae of frons on median portion, approximately 6 times smaller than maximum width of vertex ( Fig. 16C View FIGURE 16 ). Clypeus approximately 4 times longer than its maximum width; median carina of clypeus strongly marked, does not touch epistomal suture, present on distal ¾ ( Fig. 16C View FIGURE 16 ). Pedicel oblong, approximately 3 times longer than scape ( Fig. 37F View FIGURE 37 ). Scape long without cuticular denticles ( Fig. 37F View FIGURE 37 ).

Thorax: anterior margin of pronotum with tapered apex, lateral longitudinal carinae converging at an angle on anterior margin and subparallel to each other towards posterior margin; median longitudinal carina of pronotum present, but weakly marked; posterior margin of pronotum deeply concave in the middle; pronotum without pustules on posterior margin ( Fig. 16D View FIGURE 16 ); median longitudinal carina of mesonotum present, strongly marked and lateral longitudinal carinae of mesonotum present, weakly marked ( Fig. 16D View FIGURE 16 ).

Forewing: RA and RP veins with the apex gently curved anteriorly; r-m cross-vein present; ir cross-vein distant from r-m2 cross-vein, not aligned; MP vein with four branches with uncurved apex; first bifurcation of MP vein arising before r-m cross-vein; m-cu cross-vein absent; CuP vein approximately 3 times longer than Pcu + A 1 vein; apex of clavus with straight angle ( Fig. 40C View FIGURE 40 ).

Hind wing: first bifurcation of MP vein arising before m-cu cross-vein ( Fig. 40D View FIGURE 40 ).

Legs: metatibia with 8 apical spines; metatarsus with 6+6 apical spines.

Abdomen: posterior half of sternites IV + V and VI with four long, thin, whitish setae; posterior margin of sternites VII semi-rounded in posterior view. Female ( Fig. 16B View FIGURE 16 ). Similar to male, except for the coloration of some body parts (ranging from light brown to dark brown) and forewing (ranging from light brown to dark brown) and upper half of sternite III pale yellow ( Fig. 16B View FIGURE 16 ).

Male terminalia ( Figs 17A–G View FIGURE 17 ): Pygofer with posterior margin without projections, with sparse setae in posterior view ( Fig. 17B View FIGURE 17 ). Gonostyli with rounded apex in lateral view, outer margin with short projection and with a rounded apex near apex and, inner margins with some micro setae ( Fig. 17D View FIGURE 17 ). Phallic complex ( Figs 17A, B View FIGURE 17 ): periandrium semi-oval with median prolongation basally in dorsal view, dorsal margin serrated and without indentation, and ventral margin with short indentation at the apex ( Figs 17F, G View FIGURE 17 ). Inner sclerotised plates slender, with serrated margin and surface with small spiniform projections ( Figs 17F, G View FIGURE 17 ). Anal tube (segment X), short, apex rounded in dorsal view, with few sparse setae dorsally ( Fig. 17B View FIGURE 17 ).

Female terminalia ( Figs 18A–G View FIGURE 18 ): pygofer with numerous setae in posterior view ( Fig. 18B View FIGURE 18 ). Gonapophysis VIII (first valvula) robust, with a few setae on median region and covered with small spiniform projections in the basal half in lateral view; four lateroapical projection of unequal sizes with irregular teeth on dorsal margin in lateral view ( Fig. 18E View FIGURE 18 ). Bursa copulatrix densely filamentous apically, acute apex, covered by many setae laterally near to apex in lateral view ( Fig. 18E View FIGURE 18 ). Gonapophysis IX (second valvula) robust, forked on apical half, lobes with pointed apex, strongly curved latero-ventrally in dorsal view ( Fig. 18D View FIGURE 18 ). Gonoplac (third valvula) subtrapezoidal, apex rounded with several setae apically and sparse setae laterally near apex and small spiniform projections in the basal region, in lateral view ( Fig. 18C View FIGURE 18 ). Anal tube (segment X), short, apex smoothly reentrant, with sparse setae in dorsal view ( Fig. 18A View FIGURE 18 ).
