Distribution. China (Liaoning, Ningxia, Gansu, Shaanxi, Henan, Hubei, Sichuan, Yunnan).

Etymology. This new specific name “ qinlingium ” is based on the locality of specimen collected mainly in Mts. Qinling from China.

Remarks. The new species is similar to M. annulitibia Takeuchi, 1933 , but differs from the latter in having postocellar area about 2 times broader than long; hind tarsomere 1 largely pale yellowish white at apex, shortly black at base. In M. annulitibia , the postocellar area is 2.5 times broader than long; the hind tarsomere 1 is entirely black. It is easy to be distinguished from other known species.
