Mortelmans, J., 2020, Resurrection of the name Limnia testacea (Diptera: Sciomyzidae), with L. setosa as a new synonym, and the first record of L. testacea from Mongolia, Zoosystematica Rossica (China) 29 (1), pp. 101-108 : 106

Synonymy of Limnia setosa Yano, 1978 and Limnia testacea Sack, 1939

When trying to associate the male specimen from NRM with either L. setosa or L. testacea , it has become clear that both the species are extremely similar. The keys, descriptions and redescriptions indicated extreme similarity between L. setosa and Ph. testacea . Moreover, the published drawings of the male terminalia of both the species are extremely similar as well and do not aid researchers in discriminating between the two species.

Because of the morphological similarities of the males described above, I compared external characters of the female type specimens. It was determined that the type specimens of both L. setosa and Ph. testacea are without any doubt conspecific. The types of both the species are depicted in Figs 2–6, and the characters are summarised in Table 1.

Limnia setosa Yano, 1978 , syn. nov. is hereby assigned as a junior synonym of Limnia testacea Sack, 1939 .
