Body generally deep yellowish brown (75), contrasting with regions in dark brown (59) on carinae, extremities and abdomen dorsally, and strong yellowish brown (74) on head and parts of mesonotum. Tegmina with some hyaline regions and colors ranging from light yellowish brown (76) to dark yellowish brown (78) which takes place mainly in a dark spot with two hyaline dots between the postclaval margin and anterior cubital area. Body length. Male. 3.0– 3.7 mm (n = 3); Female. 3.9–4.0 mm (n = 2). Head. Vertex (Figs. 29A, C): approximately 3.0 times wider (0.3) than long (0.1); apical compartment narrows and medially elongated, approx. 2.8 times wider (0.2) than medially long (0.07); apical transverse carina (0.294) slightly larger than the subapical carina (0.262); angle formed by the caudal margin, triangular. Frons (Fig. 29B): 1.2 times longer (0.6) than wide (0.5), approx. 1.6 times wider medially than apically (0.3); median carina evanescent; anterior region of the frons large laterally, and moderately concave apically. Frontoclypeal suture semicircular, convex.. Postclypeus (Fig. 29B): median carina weakly developed. Anteclypeus (Fig. 29B): median carina moderately developed. Rostrum in ventral view reaching the hind coxae. Thorax. Pronotum (Figs. 29A, C): submedian carinae weakly developed; hind margin obtusely angled. Mesonotum (Fig. 29A): median carina well developed but evanescent distally; lateral carinae strongly developed and slightly closer near the pronotum than distally. Tegmina (forewings) (Figs. 29D): length 5.2 mm; tegmina with some hyaline regions and colors ranging from Light yellowish brown to Dark yellowish brown and two round and hyaline patches on the CuA1 and CuA2 veins in the C5 cell, and darker in this region; in addition, the tegmina exhibit long bristles mainly in CuP, Pcu, A1 and A2. fork of ScP+RA and RP, ahead of forks CuA1 and CuA2; C5 approx. half the size of C1; mcu-1 closest to the basal cell that r-m1; r-m1 and m-cu1 occurs ahead the first MP fork; simple tubercles in all veins; petiole in RP2.2+RP2.3 moderately developed; 12 apical cells; 7 subapical cells. Posterior legs. Hind tibia (Fig. 29E): approximately 1.3 mm; with 3 lateral spines, the first one closest to the small femur. 1 st tarsomere (Fig. 29F): 7 apical teeth the outer and inner lateral teeth the largest, and the intermediate teeth with approx. the same size. 2 nd tarsomere (Fig. 29F): 9 apical teeth, the 2 external ones bigger, and the intermediate ones smaller; 3 thin setae, one separated by apical teeth without setae. Male terminalia. Pygofer (Figs. 30A–C, H): bilaterally slightly asymmetric; in right lateral view, dorsocaudal margin totally convex, wider medially; in left lateral view, dorsal margin irregular with two small concavity and one convexity medially; caudal margin straight; in ventral view, ventromedian process triangular, slightly wider than long. Anal tube (Figs. 30A–C; 31A–B): short and bilaterally slightly asymmetric; in lateral view ventroapically with two acute processes moderately elongate; in dorsal view epiproct moderately developed, with distal margin straight; paraproct long, with distal margin rounded. Genital styles (Figs. 30A–C, H; 31C–D): slightly asymmetric; in right lateral view, slightly elongated apically; in left lateral view, rounded apically. Aedeagus (Figs. 30D–G; 31F–I) tubular, asymmetric. Shaft of the aedeagus with two movable spines, one bifid; in left lateral view, without spines; in right lateral view with two wide spines, 1 st spine short, apically curved and flattened at the base (b), occurs apically on the shaft; 2 nd spine slightly larger, tubular and bifid (a) occurs near the apex of the shaft below the first spine; ventral ridge dorsally developed, with two rows of teeth towards the right lateral, almost reaching half the length of the shaft. Flagellum thin, without spines, and with a spine-like process flattened apically. Female terminalia. Anal tube (Figs. 25A, C): very short; moderately elevated dorsally with two grooves pronounced laterally; epiproct and paraproct flattened dorsoventrally; in dorsal view, epiproct triangular, and rounded apically. Gonocoxae VIII (Figs. 25A, B): truncated, in caudal view larger medially; in lateral view with lateral carinae well developed, almost straight. Ovipositor (Figs. 32 A-B): in lateral view, sabre-shaped curved upwards dorsally, slightly surpassing or no surpassing the anal tube. Etymology. The specific epithet serratilis comes from Latin and means serrated and refers to the serrated ventral ridge on aedeagal shaft of the males. Diagnosis. P. serratilis sp. nov. can be distinguished from other Pintalia species by its typical wing pattern characterised by two round and hyaline patches on the CuA1 and CuA2 veins in the C5 cell, and by components of the male terminalia, such as short anal tube and developed paraproct (large); exhibiting two rows of teeth dorsally on base of the aedeagal shaft, and two wider spines apically, one of which bifid.
