Genus Trocosspicus Yakovlev, Naydenov et Penco , gen.n.

Type species: Trocosspicus haxairei Yakovlev, Naydenov et Penco , sp.n.

DESCRIPTION. Female. Size relatively big. Antenna 2.5 times shorter than fore wing in length, bipectinate, setae long: in medium third of antenna 3−4 times longer than antenna stem in diameter. Thorax and proximal portion of abdomen densely covered with coal-black scales, distal segments on upper side – with orange scales.

DIAGNOSIS. The differentiating character of the new genus is the relatively big size of the adult and the external characters: the tiny bright orange spots on the wings on the dark background. Currently, it's impossible to give a more detailed diagnosis, as only females of the new genus are known; but the special external characters allow us to decide on the allocation of a new genus.

ETYMOLOGY. “ Trocosspicus ” is an anagram of the genus name “ Cossus ” and the climatic region of the genus habitat “tropic”.
