Hubei: • 1 male, 3 females, Lichuan, Fubaoshan , 1,230 m, 2021. V. 19, leg. Jin-Teng Zhao ( CCCC) .

Description.

Male (Fig. 19 ). BL = 3.24–4.88, BW = 0.96–1.54 mm. Coloration similar to the nominate subspecies except for the integument of elytral apices becoming gradually lighter, making the apical band poorly defined; the appendages particularly the antennal flagellomeres and tibiae relatively lighter; and the pronotal disk lacking the median yellowish pubescent stripe. Structures almost identical to the nominate subspecies except for the head weakly concave between antennal tubercles; pronotal disk more sparsely pubescent and pronotal lateral tubercles with thicker bases and significantly shorter apices.

Female (Fig. 20 ). BL = 3.38–4.65 mm, BW = 1.07–1.50 mm.

Remarks.

This new subspecies can be distinguished from the nominotypical subspecies by the aforementioned characters.

Four specimens from Lichuan, Hubei generally match the diagnostic features of M. d. orientalis but possess a well-defined light-colored transverse band on the elytral apices. These specimens, representing transitional forms between both subspecies, are provisionally assigned to M. d. orientalis but excluded from the type series.

Etymology.

The specific epithet is derived from the Latin orientālis, meaning eastern, referring to the distribution of this new subspecies.

Distribution

(Map 1 ). China: Zhejiang, Anhui, Hubei, Hunan.
