Head.
Dorsal surface slightly rugose, with single orange scales; surface between eyes with short white setae at basal part; genae with longer, white to metallic green setae; moderate medial longitudinal groove from base of the eyes to base anterior margin of prothorax; transverse, moderate furrow at base of eyes confluent with medial longitudinal groove, not reaching lateral margins;
eyes moderate, weakly convex from outline of head.

Rostrum.
(
Fig. 1E
) longer than wide (LR/WR: 1,27), granulate in all length; short white setae at basal part; dorsum with shallow medial longitudinal furrow and corresponding shallow concavity; in dorsal contour straight; lateral parts covered with long white to shiny green setae.
Antennae
with funicular segment I 1,5 times longer than II, segment II nearly two times longer than III, segments III – VI as long as wide, segment VII larger, wider than long.
Prothorax
sub globular, nearly same width and length (LP/WP: 1,04), strongly rugose,
293 without setae or pubescence on disc; widest just at the middle; with the following markings of round, shiny orange shales: 1) transverse line along anterior margin in all length; 2) transverse line just after the middle in all length; shallow longitudinal medial groove on disc; anterior margin with short pubescence.
Elytra
sub-ellipsoidal, (LE/WE: 1,51), wider than prothorax, twice as long as prothorax (WE/WP: 1,38; LE/LP: 2,0); rugose in all length, without expressed puncture rows; with short brown setae along suture from apical ½ to apex; each elytron with the following scally markings of round shiny orange scales: 1) two irregular spots at basal part; 2) 4-5 smaller spots at medial part; 3) three elongated longitudinal spots at apical part; 4) one longitudinal line at apical part near suture. Male genitalia as shown in

Female unknown.
Differential analyses.
The new species by scally markings on prothorax and elytra can be referred to
M. (M.) lanaoensis
Bollino, 2021
(
Fig. 8
,
Fig. 1F
) but can be easily distinguished by features of rostrum that refers species to subgenera
Trachycyrtus
.
Distribution.
Mindanao Island, Agusan Province.
Etymology.
The specific epithet is related to similar general appearance to
M. (M.) lanaoensis
Bollino, 2021
