A new species, B. kirata Volynkin & N. Singh, sp. nov., similar to B. germana, is described from India and Nepal. The existence of two colour forms in some species of the genus Barsine Walker, 1854 is revealed. A new synonymy is established for Barsine germana (Rothschild, 1913), which includes two forms that were described as three different species: Barsine germana (Rothschild, 1913) (the yellow form) = B. valvalis Kaleka, 2003, syn. nov., and B. thomasi Kaleka, 2003, syn. nov. (the red-spotted forms).
Asia, Barsine kirata, B. valvalis Kaleka, B. thomasi Kaleka, new species, new synonymy, red and yellow forms
Until recently, Barsine Walker, 1854 was considered to be a very large and polyphyletic genus including more than a hundred valid species (
Dissections of numerous specimens of various species of Barsine displayed the existence of two colour forms in some of them: the common form having reddish forewing pattern elements together with black ones, and the yellow form lacking reddish forewing pattern elements. The latter, yellow form is usually very rare and has so far been found only in B. defecta (Figs
The red and yellow forms of some species have been described as distinct species, as in the case of Barsine germana (Rothschild, 1913) (the yellow form; Figs

The holotype of B. germana is undissected. However, the senior author has microscopically examined the tips of its valvae, which have the distal saccular process structure identical to those in the holotypes of B. valvalis and B. thomasi. The holotype is also externally similar to specimens from the same region of India, and clearly different from B. kirata, sp. nov. A detailed comparison of B. germana with B. kirata sp. nov. is provided below.
Barsine germana varies considerably in its size: the forewing length is 13–17 mm in males and 16–23 mm in females.
