Ivindonola gen. n.

( Figs 18 , 30 )

Type species: Ivindonola ipassa sp. n.

Diagnosis. The facies of the type species of the new genus is reminiscent of Brunneonola due to its similarly small size, brownish coloration and the red-brown terminal area of the forewing. Despite the similar habitus, Ivindonola displays a rather unique and distinct genital morphology expressed by the long, pointed and densely setose uncus, a character which is rather prevalent in Meganola , the remarkably narrow tegumen, the medially strongly constricted, unilobate valva, the lack of a harpe, and the presence of a short membranous lobe of the sacculus. The combination of these characters is unknown in any other noline genera and thus a new monotypic genus is erected here.

Description. Adult. Male ( Fig. 18 ). Forewing length of type species 7 mm. Head small, antenna short, bipectinate with short, finely ciliate rami, distal quarter filiform; labial palp short, porrect, dark brown; frons and vertex grey. Collar and tegula dark grey, suffused by pale grey scales, mesothorax and abdomen pale greyish-brown. Forewing relatively broad, elongate-quadrangular, apically rounded, ground colour pale creamy-grey with sparse, very fine dark brown suffusion; costal margin with small, rounded patches; dorsal two-thirds of terminal area redbrown. Basal and subbasal lines deleted, antemedial line gently arched, diffuse. Medial line deleted, postmedial line very fine, greyish-brown, interrupted. Subterminal line rather broad, dark brown, interrupted, represented by dark brown patches in dorsal-, small dots in ventral area; terminal line very fine, ochreous. Cilia moderately long, red-brown in dorsal, cream in ventral half. Hindwing grey, somewhat darkened apically veins slightly darker; cilia long, proximal half dark grey, distal half pale greyish-brown. Underside of wings ochreous brown with well-defined discal spots.

Male genitalia ( Fig. 30 ). Uncus relatively long, distal quarter tapered and densely setose, apex pointed.Tegumen very narrow and elongate, arms thin; subscaphium membranous with elongate, densely scobinate plate. Valva long, relatively narrow, medially strongly constricted, dorsal margin concave basally, slightly convex submedially, straight distally, weakly sclerotized. Valva apex broadly rounded, densely scobinate, ventral margin deeply concave medially, gently convex in proximal half. Harpe absent; sacculus narrow, bearing a short, longitudinal lobe distally. Transtilla weakly sclerotized, ribbon-like arms medially fused. Juxta small, U-shaped, vinculum short, V-shaped. Aedeagus long and very thin, gently S-curved, coecum long, apically bifid, Y-shaped, carina absent; vesica without cornuti or scobination.

Female. Unknown.

Etymology. The prefix in the generic name refers to the type locality of the type species of the new genus, the Ivindo National Park.
