1,9 mm
. Reddish-brown, elytra with a rounded, not well-defined black spot in the medium part and a little black spot on the apex of each elytron (
fig. 3
). Eyes conical. Pronotum 1,45 times broader than long, broadest between the anterior angles, strongly punctate, margin with strong teeth, surface very convex, sloping towards the margin, anterior callosities not prominent, margin nearly straight. Elytra stout, hairs uniform semi-erected, shoulders well developed, strongly punctate on the anterior part, less to the posterior part. Legs slender, tarsi with five segments, posterior tarsi with four segments (only in male), anterior tarsi segments 1-4 moderately widened (only in male). Antennae slender, club well developed, segments 3-7 longer than broad but unequal, segment 8 nearly moniliform, segment 9 and 10 conic and nearly broad as long, segment 11 oval, longer than broad, conical. Parameres as in fig. 6.
C o m m e n t Distinguished from
M. bimaculata
and
M. sinensis
by its strong punctuation (pronotum, elytra), Parameres triangular (fig. 7). Very similar to
M. zhejiangensis
, distinguished by the non-prominent callosity and the parameres. Also similar to
M. micramboides
(REITTER, 1874)
, which is strongly stout, with a pronotum broader and with rounded margins (fig. 11). Distinguished from
M. schuelkei
nov.sp.
by its rounded, not well-defined spot.
