Haderonia tancrei (Graeser, 1892)

Varga, Zoltán, Gyulai, Péter, Ronkay, Gábor & Ronkay, László, 2018, Review Of The Species Groups Of The Genus Ctenoceratoda Varga, 1992 With Description Of Four New Species And A New Subspecies (Lepidoptera, Noctuidae), Acta Zoologica Academiae Scientiarum Hungaricae 64 (1), pp. 51-74 : 54-55

The tancrei -group

Diagnosis – Medium-sized or large moths with robust body, very long and strongly bipectinated male antennae and elongated-triangular forewings. Colouration of forewings mostly greyish-ochreous-brownish, rarely rufous with regular but often faint maculation. Reniform stigma often shows an acute whitish stripe basally. Male brush organ regularly present.

In the male genitalia, the uncus is relatively long, the cucullus is rounded triangular, often slightly inflated or with small incision; the ampulla is elongate, more or less curved. Vesica tubular, extremely long with long stripe of fasciculate cornuti.

The species of this group can be recognised externally by the greyish or rufous-brownish colouration, the presence or absence of whitish marking at the basal part of the reniform stigma. The group features of the male genitalia are the characteristic shape of the “head” of cucullus, and configuration of the ampulla and the length of the fascia of cornuti in the vesica.

Ctenoceratoda cyanochrea sp. n.

Bionomics and distribution – Almost all species are confined to the Tien-Shan mountain system where they are mostly typical for the semi-desert like habitats of low or moderate altitudes (contrasting to the next group!). Two species are relatively widely distributed in Central Asia ( tancrei , graeseri ), the other species seem to be rather localised and infrequent.
