Nephelomilta wolfgangspeideli Volynkin & Černý , sp. nov.

( Figs. 29 , 95 )

Type material. Holotype ( Figs. 29 , 95 ): ♂, “ XI.2015, South Vietnam, Lam Dong province, Lac Duong district , Tay Nguyen Highlands, Nui Ba National Park, leg. Vo Van Nhon ”, slide AV2343 (Coll. NHMUK, ex coll. CAV).

Diagnosis. Length of forewing is 11.5 mm in male. The species is similar externally only to Javanese N. pellucida due to its red subterminal forewing area (in all other red patterned species the subterminal area is white with three large red spots) and the dark greyish hindwings, but differs by the narrower forewings, the broader transverse lines, the larger medial spot, and the larger discal spots. The male genitalia differ clearly from those of N. pellucida in the narrower apical lobes of the juxta, the less developed medial costal angle, the much broader distal section of the costa, the much larger, lobe-like apical process of the costa, the larger ventral-apical costal process, the broader sacculus with the shorter subapical process, the slightly larger carinal plate of the aedeagus, the smaller distal diverticulum of the vesica having the cluster of larger spines, the absence of a subbasal diverticulum, and the medial diverticulum narrower and directed basally. The male genitalia of N. wolfgangspeideli sp. nov. differ from those of it relatives N. effracta and N. pseudoeffracta in the broader distal section of the costa, the broader ventral-apical costal process, the smaller, broadly trigonal ampulla, the broader subapical saccular process, the smaller aedeagus, the significantly narrower vesica, the absence of a subbasal diverticulum, and the significantly smaller medial and distal diverticula.

The female is unknown.

Distribution. South Vietnam (Lam Dong province).

Etymology. The species name is dedicated to Dr. Wolfgang Speidel (Munich, Germany), a famous expert in the Noctuoidea and Pyraloidea taxonomy and the authors' friend.
