Poliana laucheana
Foretibia with a prominent apical spine exteriorly, not present in Poliana natalensis. Hindtibia with long apical spur almost equal in length to the 1st tarsal segment. Hindtarsus with 1st segment about 1.5x as long as segments 2-5 together. Forewing upperside similar in appearance to pale specimens of Manduca rustica; antemedial area white, especially posteriorly; conspicuous white discal spot; large, olive or yellowish-olive medial costal area present centred on the discal spot, the colour spreading distad to the margin; three dentate discal lines present, the space between the 2nd and 3rd almost white; no longitudinal black streaks present between veins M3 and CuA2. Abdominal tergite 8 without stridulatory scales.
Male genitalia: Uncus not divided, dilated just before apex, which curves ventrad and is pointed; the widened part convex dorsally, weekly carinate, with the carina extending to the apex; ventral side prismatically carinate. Gnathos nearly as long as uncus in lateral view, narrowing to the sinuate apex. Valve of almost constant width from middle to rounded apex; inner surface deeply concave ventrally in the middle; a long patch of narrow, non-dentate, lanceolate stridulatory scales present, all short apart from the middle ones, which are strongly prolonged and are erect, forming a conspicuous, long, high crest. Harpe lying in the inner cavity of valve, comb-like, carrying on its dorsal edge several large, pointed teeth, the apical tooth projecting from the cavity. Phallus without external armature, but with a spiniferous flap inside.
Female genitalia: Ostium bursae somewhat transverse, the edges somewhat raised, but with no process.
