Description ( Fig. 5 ):

Wingspan 13-15 mm; head brush creamy grey, antenna grey, scapus somewhat darker as flagellum; labial palpi with same coloration as head brush, second segment outside dark grey-brown, scales more or less prolonged; thorax and tegulae grey-brown, thorax basally and tegulae apically lighter; forewing creamy to grey, with a pattern of dark grey-brown dots and patches: two more or less clear patches on beginning of cell and before the end; base of costa; from base to 1/2 numerous thin strigulae, four short stripes on costa from 1/2 to apex, some very small dots on base of fringe; the whole wing overlaid with scattered darker or brownish scales; hindwing grey.

Male genitalia ( Figs 17-23 ): Uncus with two socii, inside, near base a pointed strong sclerotized tooth, tegumen ventrally prolonged into a long bifurcate saccus; valva short, more or less triangular with rounded apex, inside subapical with a strong sclerotized pointed tooth, transtilla narrow, long, phallus longer than uncus-tegumen-saccus, thin, basally rounded, at the beginning of second half outside with some small pointed thorns, subapical additional smaller thorns, on apex a bent pointed process, at crease a strong sclerotized hook, depending from preparation not everytime visible (see Figs 20-23 ).

Female genitaliagenitalia ( Fig. 24 ): Ostium clear impressed, laterally bristled rounded lobi, major part of ductus bursae with almost longitudinal sclerotizations, signum cone-shaped, with fine crossways sclerotizations (characteristic for the genus).

Etymology: Named after my colleague KNUD LARSEN, the collector of this new species.

Remarks:

Superficially similar to some other members of the genus (insulare, petrinellum), but clear different in the structure of the genitalia. The long bifurcate saccus and the phallus with the characteristic shape in male, and the sclerotized ductus bursae in female are unique in the genus.
