DIAGNOSIS. The forewing with two distinct dark greyish-brown longitudinal narrow stripes across the entire wing and light greyish-brown streaks along the R veins on the paleyellow background. In the male genitalia valvae are asymmetric; the left valva is almost the same width along the length, with protruding dorso-distal angle; the right valva with expanded cucullus and relatively narrow neck about 2/3 of total length; cucullus with small tooth-like lobe on the ventral margin; aedeagus slightly arcuately curved in distal part, inflated basally.

DESCRIPTION. Adult ( Fig. 1 ). Wingspan 13 mm. Head with appressed scales. Antenna slightly longer than 2/3 of wing length. Second segment of palpus with tuft of long paleyellow scales, darker on outer surface; third segment completely hidden in the tuft. Head,

thorax and background of the forewing are pale-yellow with scattered dark greyish-brown scales. The pattern of forewing consists of two longitudinal dark greyish-brown narrow stripes, running through the entire wing: one stripe in the middle of wing from the base to outer edge under the apex, the second stripe below the first one from the base of the wing to the tornus; short light greyish-brown stripes placed along the R-veins. The hindwing greyish-

yellow.

Male genitalia ( Figs 2, 3 ). Uncus with setaceous socii and finger-like process widened towards the base and curved ventrally at the apex, with sclerotized dorsal rod along the median axis. Gnathos absent. Tegumen widened towards the base, its distal part is almost equal to uncus in width, posterior margin convex, the proximal part with two semi-oval sclerotizations along anterior margin, ventral wall distinct, antero-lateral lobes joined with parategminal sclerites. Parategminal sclerite of complicated shape and articulated with tegumen, valva and vinculum; its dorsal rounded lobe-like part joined with tegumen, medial trapezoidal part joined with valvar base, ventral part joined with vinculum. Valvae are asymmetric, inflated and with modified setae on the medial surface. The left valva is larger than right one, slightly narrowed in basal part, almost equal in width along the medial part and with protruding dorso-distal angle; the right valva with dilated oval cucullus, the latter with protruding dorsal angle and tooth-shaped lobe on the ventral edge; the typical for anarsiin moths processes on the ventral margins of valvae are rudimentary and faintly distinguishable. Aedeagus slightly arcuately curved in distal part, with narrow longitudinal sclerotization ventrally, and with small ridge-like ventral sclerotization in basal part; inflated basally, its basal part 4 times wider than distal one; the opening for ejaculatory ductus slightly shifted dorsally. Vinculum narrow, band-like in lateral part, which 4 times as wide as latero-ventral triangular widenings; with short triangular saccus.

Female genitalia and host plant unknown.

DISTRIBUTION. North Africa ( Morocco).
