Myrmus calcaratus (misidentification): Hsiao (1977: 267, in part) (in key, photo, figure, redescription, distribution).

Discussion. Hsiao (1977) did not treat this species; it was recorded from Hulunbuir, Inner Mongolia by Nonnaizab (1986, 1999) (as M. m. gracilis Lindberg, 1927 ) and from Mt. Liupan, Ningxia by Zheng & Gao (1990) and Liu et al. (1993) (without specification of subspecies). Material deposited in Chinese institutions, examined during the present study, revealed that the species is rather widely distributed in temperate parts of China, although apparently not common. Although the holotype of M. varicornis is conspecific with M. calcaratus therefore it is a junior synonym of the latter species, additional records of M. tenuicornis by Hsiao (1965a: 60) and records of M. calcaratus by Hsiao (1977: 267–268) at least partly pertain to M. miriformis (see under the subspecies).

Distribution. A Transpalaearctic species; global and local distribution maps were presented by Putshkov (1986: 98, fig. 54) and Moulet (1995: 233, map 34), respectively. Two subspecies, the nominotypical one and M. m. gracilis , were recognized by Kerzhner (1966), and they were recognizable in the examined material as well. The specimens are listed according to the subspecies below, also mentioning the wing morphs (b = brachypterous, m = macropterous).
