Barsine obsoleta

Volynkin, Anton V. & Černý, Karel, 2017, A review of the Barsine obsoleta species-group with description of a new species from Vietnam (Lepidoptera, Erebidae, Arctiinae), Zootaxa 4254 (2), pp. 188-200 : 189

Barsine obsoleta species-group

Members of the group are medium-sized moths with very different wing coloration, but similar male genitalia structure. We include to the group species having the following characteristic features of the male genitalia ( Figs. 19–22 ): 1) the distal saccular process without a dorsal lobe (whereas all other known Barsine species except Barsine striata ( Bremer & Grey, 1853) ( Figs. 17, 18 , 23 , 30 ) have a dorsal lobe of distal saccular process); 2) 1st medial diverticulum of vesica is long and curved; 3) 2nd medial diverticulum is bilobate, its main lobe is broad and covered with strong short cornuti of different size, and the additional lobe is smaller, conical, with strong scobination. Despite the similarity of the male genital capsules of B. striata and the B. obsoleta species-group due to absence of a dorsal lobe of the distal saccular process, the male genital structures of the B. obsoleta speciesgroup are well separated from those of B. striata in the much narrower uncus, the broader apical lobe of valva, and especially the vesica configuration.

The Barsine obsoleta species-group includes the three known species reviewed below.
