Type specimen. Holotype: Male , North Madagascar, north of Mangindrano, protected area, Integral Natural Reserve 4, alt. 1,950 m, Andohanimaevarano, 16–29 ix 1971, leg. P. Soga; gen. slide no. CIS-7391 (in MNHN).

Diagnosis. The new species is somewhat similar to M. randimella ( Viette, 1957) in characters of the habitus and male genitalia, but it can be distinguished from it by the more grayish-orange ground color of the forewing and the pale orange color of the hind wing, and a stouter aedeagus in the male genitalia.

Description. Male ( Figs. 11A, B ). Wingspan, 22.0 mm. Head: pale grayish orange centrally, with creamywhite, long erect scales laterally. Antenna slightly longer than forewing; scape elongated, slightly dilated distally, yellowish white speckled with brownish scales; flagellum yellowish white, without distinct annulations. 2 nd segment of labial palpus thickened, pale grayish orange on outer surface, paler on inner surface; 3 rd segment as long as 2 nd segment, yellowish white laterally, brownish ventrally. Thorax: tegula and thorax grayish orange dorsally. Forewing slightly dilated distally; ground color pale grayish orange, with scattered brownish orange scales; antemedian band absent; postmedian band oblique, sharply angled on vein M 1; costa arched around basal 1/3, nearly straight medially, then slightly oblique beyond 3/4; apex rather acute; termen oblique, concave above middle; fringe concolorous, with brownish median line; venation with R 5 to termen; M 2 close to M 3 at base, nearly parallel to M 3; CuA 1 and CuA 2 stalked for 1/2. Hind wing venation complete; base of M 2 remote from M 3 +CuA 1; M 3 and CuA 1 stalked for basal 1/3. Abdomen ( Fig. 11E ): grayish orange dorsally; spinose zones narrow, lying along posterior edges of terga.

Male genitalia ( Figs. 11C, D ): Uncus long, slender, arched, reaching caudal edge of basal plate of gnathos. Basal plate of gnathos elliptical; median process very small. Tegumen strongly angled at latero-distal corner, deeply concave on anterior margin. Valva slightly angled in basal 1/4, deeply concave on costa; ventral margin deeply emarginated before lower corner of cucullus; cucullus elongated, slightly upturned, costal margin nearly straight, ventral margin gently arched, with round apex. Juxta deeply concave on caudal margin. Vinculum a narrow band. Aedeagus stout, broader than cucullus, as long as valva; dorsal margin nearly S-shaped, produced apically; cornuti consisting of a S-shaped spine (measuring about 1/3 the length of aedeagus) and a cluster of numerous minute spinules.

Female unknown.

Distribution. Madagascar (North).

Etymology. The species name is derived from the Latin word septentrio, -onis (= North), referring to the northern location of the type locality.
