(Figs. 2, 7, 9)
Diagnoses. Gisilia tamrae is indistinguishable from G. melanobasis in external appearance. Examination of genitalia is necessary for reliable identification. The male genitalia of G. tamrae n. sp. differ from those of G. melanobasis in having a digitate cucullus (spatulate in G. melanobasis). Gisilia tamrae is similar to G. thoracista in the female genitalia but differs from the latter in having a larger swelled basal section of the ductus seminalis and larger signa (Fig. 9 vs. Fig. 10).
Description. Head—Vertex black, tinged with greyish orange on anterior 1/3; frons pale greyish orange, intermixed with dark brown scales. Antenna 3/5 as long as forewing; scape black; flagellum brownish black basally, gradually paler to pale brown apically. Labial palpus upcurved, pointed apically, black dark brown on outer surface, pale greyish orange, sparsely intermixed with black scales on inner surface; 3rd palpomere speckled with pale greyish orange on outer surface. Thorax—Tegula and mesonotum black; mesoscutellum pale greyish orange. Foreleg with coxa and femur brownish black; tibia brownish black, with pale orange bar at apical 1/3 and pale orange ring apically; tarsomere brownish black, with pale orange ring apically. Midleg with coxa pale yellowish grey; femur dark brown; tibia brownish black, with pale orange patch basally and pale orange ring apically; tarsomere brownish black, with pale orange ring apically. Hindleg with coxa and femur lustrous, pale yellowish grey; tibia brownish black dorsally and laterally, pale orange ventrally; tarsomere brownish black dorsally, pale yellowish grey ventrally, with pale orange ring apically. Forewing length 3.8–4.3 mm, pale greyish orange, suffused with dark brownish grey costally, dorsally, and apically (this suffusion broader in male); basal area black; black spots present at middle and distal end of discal cell, and at middle of anal vein fold; pale orange spot present on distal 1/5 of costa; fringe dark brownish grey. Hindwing grey; fringe dark yellowish grey. Male abdominal segment VIII—tergal process and sternal processes absent. Male genitalia (Fig. 7)—Uncus absent; tegumen subrectangular; tuba analis elongate. Valvae asymmetrical; each valva sub-quadrate in basal half, digitate in apical half, with a zone of long setae at middle of costa and a bulge basally; right cucullus densely setose on apical are; left cucullus narrower than right cucullus, densely setose along lower area of apical half, with two long, spiniform setae apically; right saccus with setose hump apically; left sacculus with setose, digitate process apically. Juxta ankylosed with phallus. Vinculum quadrate; saccus absent. Phallus bi-sinuous, obliquely-cut apically; coecum narrow, slightly curved. Female genitalia (Fig. 9)—Oviscapt elongate, heavily sclerotized, acuminate apically, 3/4 as long as apophyses posteriores; oviscapt cone slightly sclerotized laterally, setose apically. Apophyses posteriores as long as apophyses anteriores, with one of basal branches reaching near apex of oviscapt cone. Sternite VII with linguiform, sclerotized depression near ostium bursae. Ductus bursae funnel-shaped in caudal 1/3, broadened on cephalic 2/3, 2.3× longer than corpus bursae; ductus seminalis arising at middle, broadened basally. Corpus bursae obovate, with two signa on caudal 1/3; signum as spinulate, elliptical zone.
