Volynkin, Anton V. & Černý, Karel, 2019, A review of the Barsine phaeodonta (Hampson, 1911) species-group, with descriptions of four new species from Indochina and India (Lepidoptera, Erebidae, Arctiinae), Ecologica Montenegrina 21, pp. 70-79 : 76

Barsine meyi Volynkin & Černý , sp. nov.

( Figs 9, 10 , 19 )

Type material. Holotype ( Figs 9 , 19 ): male, “ Myanmar, Chin- Hills , Myohaung Camp, 2060m, 3–5.X.2002, leg. W. Mey, LF” / “Natma Taung NP, Area of Mt. Victoria ”, slide AV4239 Volynkin (Coll. ZMB).

Paratype: 1 male, same data as in the holotype, slide AV4235 Volynkin (Coll. ZMB) .

Diagnosis. Forewing length is 10.5–11 mm in males (wingspan 22.5–23 mm). Externally, B. meyi ( Figs 9, 10 ) is very similar to B. phaeodonta ( Figs 1–4 ), and can be distinguished by its slightly narrower subbasal forewing area only. The male genitalia of B. meyi ( Fig. 19 ) differ from B. phaeodonta ( Fig. 17 ) by their less curved costal margin of valva, less prominent costa apex, broader medial costal process directed ventrally (in B. phaeodonta that is narrower and directed basally), much shorter distal saccular process being apically blunt, much broader aedeagus, the presence of the sclerotized dentate band at the base of the vesica ejaculatorius, shorter and much broader dorsal diverticulum bearing a broader apical bunch of spinules, and narrower distal diverticulum bearing a broader apical bunch of spinules.

The female is unknown.

Distribution. The new species is known from its type locality only (North West Myanmar, Chin State).

Etymology. The species is dedicated to Dr. Wolfram Mey, collector of the type series.
