( Figs 4, 5 , 8, 9 , 13 )

Bulborhodopis inornatus Holzschuh, 2017: 159 .

Type material examined. Hඈඅඈඍඒඉൾ: VIETNAM: J, ‘N. VIETNAM ( TONKIN) / TAMDAO / 12.– 24.5.1989 / PACHOLÁTKO Leg.//HOLO- TYPUS / Mimapatelarthron / bulbiferum n. sp. / det. C. Holzschuh 2017 ’ ( CCH). Two photographs examined provided by Carolus Holzschuh.

Other material examined. CHINA: Yඎඇඇൺඇ: 1 ♀, ‘CHINA. Yunnan, Funing / Lidazhen, Ligongcun / 1,370 m 2011.VI.13 / leg. Chao Li’ ( CCCC). Hൺංඇൺඇ: 1 J, ‘CHINA. Hainan, Ledong / Jianfengling / 1,412 m / 2020, IV-30, Leg.Y.-H. Li’ ( CCCC); 2♀♀, ‘CHINA. Hainan, Ledong / Jianfengling / 1,420 m 2018.VI.18 / leg. Bin Liu’ ( CLYH).

Complementary description. Male ( Fig. 4 ). Body length 9.0 mm, elytral maximum width 2.9 mm.

Male genitalia. Tergite VIII ( Fig. 15a ) trapezoidal; anterior margin slightly prominent in middle, bearing moderately long setae. Tegmen ( Fig. 15b ) similar to that of Bulborhodopis humeralis except for lateral lobes provided with rather long and dense setae on apex. Median lobe ( Fig. 14c ) slightly longer than tegmen with acuminate apex. Endophallus in everted condition ( Fig. 15d ) similar to that of Bulborhodopis humeralis except for medial third relatively thicker and significantly S-shaped.

Female ( Fig. 5 ). Body length 9.6–10.0 mm, elytral maximum width 3.0– 3.2 mm.

Differential diagnosis. This species is most similar to M. laosense which is known so far only from the female holotype ( Fig. 12 ). HඈඅඓඌർHඎH (2017) separated it from the latter by the integument of body blackish instead of reddish-brown, presence of a transverse band in the basal half of elytra, pronotum relatively longer, and gena significantly longer than the lower eye lobes. However, based on the comparison of good quality photographs of both holotypes and the observation of further materials, the relatively lighter coloration of the holotype of M. laosense is probably the result of discoloration and the pronotal shape of both species is almost identical. Therefore, the body coloration and the pronotal morphology are not suggested to be used for the specific diagnosis. This species can be further distinguished from M. laosense by antennomere III distinctly shorter than antennomeres V to XI combined (instead of slightly longer), and meso- and metatarsi covered with intermixed pale and dark brown pubescence (instead of uniformly pale).

Distribution. Vietnam: Vinh Phu (HඈඅඓඌർHඎH 2017); China (new country record): Yunnan, Hainan.
