Diagnosis.

(See also the identification key of calamistis species subgroup, section 3.3. 2.). This species can be distinguished from the other known members of the calamistis subgroup by the combination of the following characters of the male and female genitalia: vinculum u-shaped at the outer margin, w-shaped at the inner margin with an indentation, with a large saccus; apical extension of the sacculus almost as long as the cucullus; juxta large and conical, pointed at apex, the sides rounded, the superior plate wide and long; phallus short; vesica with a small, slightly ridged, mid-ventral cornutus; ventrolateral plates of female segment A 8 twice as long as wide; ostium bursae small, transverse, in the shape of a semicircle, strongly sclerotized, with small pointed tips on each side; ductus bursae short, asymmetrically sclerotized posteriorly; ovipositor lobes at least three times longer than wide.

Description.

(Fig. 2 K – N View Figure 2 ). The external morphology of adults of both sexes has been described in great detail by Tams and Bowden (1953), Rungs (1954) and Viette (1967). The ground colour of the forewing can vary from cartridge-buff to dark ochraceous, but most of the examined specimens are rather ochraceous. — Forewing length: male 28–34 mm (x ̅ = 31.7 mm, N = 7); female 29–40 mm (x ̅ = 35.9 mm, N = 16). — Male genitalia (Fig. 3 D, K View Figure 3 ). Tegumen with moderate peniculi; vinculum u-shaped at the outer margin, w-shaped at the inner margin with an indentation, with a large saccus. Valve with sacculus and cucullus separate; costa short and narrow, heavily sclerotized, ending with a long curved spine, slightly bending outward, with an apical tooth; sacculus heavily sclerotized rounded at base with an indentation, a thick and elongated apical extension almost as long as the cucullus, adorned outwards with rows of short stout spines, pointed at apex; cucullus long, weakly sclerotized, slightly clavate at apex, with scattered and papillated hairs; juxta large and conical, pointed at apex, the sides rounded, the superior plate wide and long; uncus angled and stout at base, narrowed in distal part, pointed at apex, tufted with long hairs on upper side; phallus short, dilated at base; lamina ventralis with an elongate carinal crest; vesica with a small, slightly ridged, mid-ventral cornutus. — Female genitalia (Fig. 4 C View Figure 4 ). Apophyses anteriores with large spatulate tips; ventrolateral plates of segment A 8 twice as long as wide; ostium bursae small, transverse, in the shape of a semicircle, strongly sclerotized, with small pointed tips on each side; ductus bursae short, asymmetrically sclerotized posteriorly; corpus bursae long, without signa; ovipositor lobes at least three times longer than wide with dorsal surface bearing numerous short and stout setae, the ventral side of each lobe almost straight, tooth-shaped; apophyses posteriors more slender than apophyses anteriores.

Distribution.

Madagascar. Known from localities belonging to different vegetation mosaics (‘ lowland rain forest wetter types’ (Mosaic # 1 b), ‘ cultivation and secondary grassland, replacing upland and montane forest’ (Mosaic # 18) and ‘ dry deciduous forest and secondary grassland’ (Mosaic # 22 b )) ( White 1983) (Fig. 6 View Figure 6 ).

Ecology.

Unknown.

Remarks.

In his revision of the genus Sesamia from Madagascar, Rungs (1954) noted that specimens collected in the highlands are much darker (and slightly reddish) than the lectotype and other specimens collected in the coastal area of Nossi-Be; he named them the cannella form.
