Triplocania sevillaensis n. sp. Female

( Figs 281–286 )

Diagnosis. Ninth sternum distinctly different to that in species with marginal brown band in forewing, from R2+3 to 1A. Ninth sternum with three well delimited areas, a pigmented transverse anterior one, a mesal area projected posteriorly in the middle, with one transverse sickle-shaped pigmented area on each side of the longitudinal midline, and one mostly hyaline, narrow posterior area ( Fig. 286 ).

Color (in 80% ethanol). Body creamy, with pale brown and dark spots. Compound eyes dark brown; ocelli hyaline, with ochre centripetal crescents. Head pale brown, with brown spots, pattern ( Fig. 283 ). Antennae: scape pale brown, pedicel and flagella cream; maxillary palps cream, Mx4 distally brown. Tergal lobes of meso- and metathorax brown. Thoracic pleura with brown large area on epimeron; mesepisternum and mesepimeron dark brown, with cream spots; metepisternum cream with brown spots on top and near the coxae, metepimeron cream, with brown irregular spot. Legs cream, with tibiae and tarsi darker, apices of the tibiae and t2–t3 dark brown; coxae and femora with dark gray spots. Wings mostly hyaline, with brown veins; forewings with brown marginal band from R2+3 to 1A; pterostigma cream, distally brown ( Fig. 281 ). Hindwings with small basal area dark brown and pale brown apex ( Fig. 282 ). Abdomen pale cream, with brown subcuticular spots. Subgenital plate hyaline in the middle, pigmented area V-shaped, more pigmented anteriorly. Gonapophyses brown. IX sternum pale brown. Epiproct and paraprocts brown, with brown subcuticular areas.

Morphology. As in diagnosis, plus the following: Head: H/MxW: 1.36, compound eyes: H/D: 2.91, IO/MxW: 0.84, MxW/IO: 1.80. Vertex almost at the same level of the upper border of the compound eyes. Outer cusp of lacinial tips broad, with seven denticles. Forewings ( Fig. 281 ): L/W: 2.54, pterostigma elongate: lp/wp: 6.56; areola postica high, la/ha: 1.80, Cu1a concave. Hindwings ( Fig. 282 ): l/w: 2.75. Subgenital plate ( Fig. 285 ) wide, rounded posteriorly, densely setose. Gonapophyses ( Fig. 286 ): v1 elongate, slender, acuminate; v2 +3 widened basally, with short proximal heel; a row of seven setae on v2; distal process long, sinuous and acuminate, with abundant microsetae. IX sternum as in diagnosis. Paraprocts ( Fig. 284 ) elongate, broadly triangular, with abundant long and short setae on the posterior and external borders; sensory fields with 34 trichobothria on basal rosettes. Epiproct triangular ( Fig. 284 ) longer than wide, anterior border bilobed, posteriorly rounded; setae as illustrated.

Measurements. FW: 7100, HW: 4600, F: 1700, T: 3000, t1: 1187, t2:102, t3: 200, Mx4: 330, ctt1: 34, f1: 1300, f2: 1375, f3: 1225, IO: 735, D: 425, d: 307, IO/d: 2.39, PO: 0.72.
