(Figs 30–35)

Diagnosis. Differing from the known species in the genus, in having the forewing M eight branched, the branch nearest the areola postica forked (see also Discussion, below).

Color (in 80% ethanol). Body dark brown, with ochre brown spots. Head brown, with dark brown spots (Fig. 32). Compound eyes dark brown, ocelli hyaline, with ochre centripetal crescents. Fore legs brown, hind legs cream, frontal and middle coxae with dark brown spots, hind coxae with proximal and distal brown spots; femur with apical brown ring. Forewing with a marginal, pigmented band from R4+5 to confluence of Cu2-1A, with clear areas on sides of some vein ends at wing margin; pterostigma brown with large, central clear area (Fig. 30). Veins pale brown, with dark brown areolae on setal insertions. Abdomen brown, with ochre subcuticular spots. Epiproct and paraprocts pale brown; subgenital plate with dark brown lateral and clear central area, with dark brown areolae on setal field.

Morphology. As in diagnosis, plus the following: Areola postica narrow, tall, almost reaching M, apex rounded (Fig. 30). Hindwing M four branched (Fig. 31). Subgenital plate (Fig. 33) broad, posteriorly rounded, with setae and pigmented areas as illustrated. Gonapophyses (Fig. 35), v1 long, slender, acuminate, v2 +3 proximally wide, with a pointed heel, v3 with a row of four large setae, as illustrated, distal process straight, acuminate, with a field of microspines. Ninth sternum (Fig. 35) trapeziform, the anterior border wider than the posterior one; an irregular pigmented band anteriorly as illustrated. Paraprocts (Fig. 34) broadly triangular, rounded posteriorly, with setae as illustrated and sensory fields with 28 trichobothria in basal rosettes. Epiproct (Fig. 34) elongate, approximately triangular, posteriorly rounded, with setae as illustrated.
