Polymixis khumbuensis (Owada, 1981) Benedek & Volynkin & Babics & Saldaitis, 2021

Benedek, Balázs, Volynkin, Anton V., Babics, János & Saldaitis, Aidas, 2021, Review of the subgenus Lophotyna Hampson of the genus Polymixis Hübner (Lepidoptera: Noctuidae: Noctuinae), with descriptions of two new species from Myanmar, Zootaxa 4999 (1), pp. 22-40 : 33

The khumbuensis species-group

Diagnosis. Members of the species-group are characterized by the bright orange forewing colouration with a darker medial area and a distinct pattern. The male genitalia structure is reminiscent of that of the P. albirena species-group ( Fig. 23 ) but differs by the asymmetrical clavi, the apically pointed dorsal costal protrusion, the markedly more elongate cucullus, the distally wider sacculus, and the less elongate left digitus which is not protruding beyond the ventral margin of the valva. The female genitalia of the species-group differ from those of the P. albosignata ( Figs 30, 31 ) and P. albirena species-groups ( Fig. 32 ) by the less elongate ductus bursae and the more weakly sclerotized appendix bursae.
