Steleops cashiriariensis n. sp. (Female)

( Figs. 8−11 )

Color (in 80% alcohol). Body pale brown, with creamy areas as indicated below. Compound eyes black, ocelli hyaline, with ochre centripetal crescents, the upper ones thicker than the lower one. Head pattern ( Fig. 9 ) with a wide brown area from the lower margin of compound eyes, through postclypeus and labrum. Postclypeus with diagonal, pale brown striae; labrum brown. Antennae: Scape and pedicel brown, flagellum creamy white; maxillary palpomeres creamy white. Legs creamy white, hind t1 with small brown spot basally, pretarsus brown. Tergal lobes of meso- and metathorax dark brown; pleura with creamy and brown areas. Abdomen creamy white, with small, brown narrow spots on tergum and sternum of each segment, pleura creamy white, epiproct and paraprocts creamy white.

Fore wings ( Fig. 8 ) maculate, without defined brown pigmented transverse band, but with large brown spots from anterior end of pterostigma to CuP. Pterostigma with a dark brown irregular spot posteriorly; veins R2+3, R4+5, M1, M3 and Cu1a with pale brown spots distally, areola postica with a brown area in the middle; other brown spots and clear windows as illustrated. Hind wings hyaline, almost all the veins creamy white or translucid, some veins (M, M-Cu, Rs-M, CuA) in the central part of the wing pale brown.

Morphology. Head slightly concave at vertex, compound eyes little pedunculate, almost as long as its maximum width, H/MxW: 1.15; MxW/MnW: 1.42; compound eyes oval, C: 60 microns. Antennal flagellomeres with short, sparse setae. Fore wing ( Fig. 8 ): L/W: 2.67. Pterostigma much wider posteriorly, lp/wp: 3.12; apex rounded, almost at an angle of 90° with wing margin. Rs slightly curved and shorter than R 2+3 and R 4+5; Rs-M joined by a short crossvein. Cell M, large, rectangular; areola postica trapeziform. Hind wing Rs-M fused, Rs almost twice as long as the fused length; vein R 4+5 1.8 times as long as Rs.

Subgenital plate ( Fig. 11 ) triangular, with setae scattered on surface; median projection short, rounded, distally broad and with macrosetae along posterior margin. Ninth sternum broad, membranous. Gonapophyses ( Fig. 10 ): V1 long, slender, distally pointed, V2 distally straight, with microsetae along posterior border; V3 oval, with posterior margin straight, bearing a row of macrosetae.

Paraprocts damaged in mounting, broadly triangular, with a row of macrosetae along outer margin, sensory fields with 16−18 trichobothria issuing from basal rosettes. Epiproct basally wide, almost trapeziform, widely rounded distally, with setae along postero-lateral border.
