Diagnosis: a large, rather broad, white reniform spot starting from the costa inwards just beyond the transversal vein of the forewing. Male genitalia with a curved costa and only one bunch of spine-shaped cornuti in the vesica; female genitalia with a rounded enlarged pouch, with longitudinal folds and some sclerotizations; corpus bursae oval.
Description:
Head: (Fig. 1: C, D.) frons flat; maxillary palps near base of scaled proboscis; labial palps slender, upturned, all three segments clearly distinguishable; antennae filiform in males and females.
Thorax: forewings triangular with a clear kidney-shaped dot just beyond the transversal vein of the cell; costa with a clear antemedian line near the first fifth of the costa, black near the costa, more diffused near the inner margin of the forewing ground colour wings grey; forewing triangular, costa light yellow with clear black markings, one near the base of the wing near the tegula, one before the base of the antemedian line, one at the base of the antemedian line, one at the base of the postmedian line and one on the outer margin of the reniform whitish spot; antemedian lines lightly curved, postmedian line S-shaped with whitish reniform spot on its outer margin broad near the costa, terminating near the basal angle of the cell. Hind wings same colour as the fore wings, grey with a black almost straight antemedial line and a short almost straight postmedian line starting at the costa and ending near the first cubital vein.
Wingspan: 14-17mm.
Male genitalia: (Fig. 2: A, B.) Uncus short and broadly attached to the broad tegumen; vinculum with two long Vshaped arms, saccus small; juxta as a pear-shaped plate; valva simple: costa first straight, apically curved towards a simple point; sacculus straight towards that point; valva with some elongated setae in the middle and near the last third of the valva; aedeagus tubular, apically slightly widened and containing 12 to 13 simple, well sclerotized spines.
Female genitalia: (Fig. 3: B; Fig. 4: A,C.) papillae anales membranous with some short and long setae; apophyses posteriores about 2/3 of the length of the apophyses anteriores; sinus vaginalis membranous, widened and forming a small cup before continuing in a tubular part towards a widened, slightly sclerotized bulbous structure (Fig. 4: A); ductus bursae tubular, covered with minute sclerotizations and forming an extension near one fourth of the length of the ductus bursae, this part is also covered with much less sclerotizations; corpus bursae, oval, bulbous without any signum nor appendix bursae (Fig.4: C.).
Tympanal organs: as for the genus (Fig. 5: A)
Etymology: The name refers to the white (latin: albo-) kidney (latin: ren) shaped (latin: formis) spot near the costa and at the antemedian line of the fore wing.
Foodplant: unknown.
Distribution: Cameroon, Northern region.
