Minilimosina (Allolimosina) cerciseta Su, 2011

(Figs. 1–7)

Minilimosina (Allolimosina) cerciseta Su, 2011: 69 [male, description, illustr.]. Type locality: China, Hebei, Mt. Xiaowutai, Mt. Dongling, HT male (LKLSU).

Diagnosis. Four interfrontals. Hind first tarsomere 3/5 times as long as the second tarsomere [hind first tarsomere 4/5 as long as the second tarsomere in M. alloneura (Richards)]. The length of dm-cu shorter than distance between r-m and dm-cu; wing with pale brownish veins, C dark brown. Male gonostylus (Fig. 5) with a long and thin seta at the middle. Male cerci (Fig. 3) concave and setulose on ventral margin.

Type material. (LKLSU, in glycerine): Holotype, male: China, Hebei, Mt. Xiaowutai, Mt. Dongling, sweep, 1200–2000 m, 28.Jun.2009, Lixin Su.

Comments. Formations of male sternite 5, postgonite and gonostylus indicate that M. cerciseta is closely related to M. albinervis (Duda, 1918), M. alloneura (Richards, 1952) and M. secundaria (Duda, 1918). Furthermore M. cerciseta seems to be more closely related to M. albinervis in the following characters: four interfrontals, the length of dm-cu shorter than distance between r-m and dm-cu, formation of male sternite 5, shapes of male cerci and gonostylus, short distiphallus, but differing from the latter in having wing veins pale brown, C dark brown, male gonostylus with a long and thin seta at the middle, distiphallus with a small subcircular pale part contrasting with other sclerotized parts, male cerci not deeply concave on ventral margin. According to shared character (possible synapomorphy): cerci of male ventrally concave, M. cerciseta and M. albinervis could be sister species. M. pseudoalbinervis (Papp, 1973) and M. paralbinervis (Papp, 1973) from Mongolia also seem to be closely allied species which, however, differs from M. cerciseta by 5 interfrontals in M. pseudoalbinervis and 3 interfrontals in M. paralbinervis.

Distribution. Palaearctic: China (Hebei).
