Synonymy: Termes (Termes) carbonarius Hagen, 1858 .
Material examined: The specimens of M. carbonarius were collected from the dry evergreen forest and deciduous dipterocarp forest at Sakaerat Environmental Research Station in Nakhon Ratchasima province. Sixty soldier termites (i.e., major soldier 30 samples and minor soldier 30 samples) were used for describing.
Major soldier case: thorax and legs have brown or dark brown, abdomen sternites light brown, vertex reddish brown ( Fig. 1E View Fig ). Head; black in color, subrectangular, sides moderately convex, scantily hairy, post-clypeus brownish with a few short hairs, length of head to side base of mandibles with 4.77 mm to 5.00, width of head at side base of mandibles with 2.35 mm to 2.48 mm. Mandibles; stout, thick, and sward-shaped with dark brown, bases reddish brown, anteclypeus trapezoid, much broader than long, the inner margin of the left mandible crenulate, the right mandible without crenulations, length of left mandible with 2.74 mm to 2.86 mm. Antennae long and slender, with 17 segments; the third slightly more than twice as long as the second; the fourth segment shorter than the third and longer than the fifth. Labrum; dome-shaped or longer than broad, and broadest in the anterior half, brownish with few hairs along the lateral sides and at the base of hyaline tip, the hyaline tip triangular, not elongated or sharpened at the tip. Pronotum; crescent-shaped, twice as broad as long, anterior margin convex in the middle and slightly emarginate with a few tiny hairs on the margin, posterior margin slightly concave in the middle, lateral lobes rather broadly rounded, pronotum length with 1.40 mm to 1.56 mm, pronotum width with 2.80 mm to 3.01 mm. Mesonotum; slightly narrower than the pronotum, lateral sides angularly rounded, the metanotum nearly as wide as the mesonotum, the posterior margin almost straight. Postmentum; elongated and rectangular, the sides nearly parallel and slightly convex near the posterior margin.
Minor soldier case: thorax and legs have brown or dark brown ( Fig. 1G View Fig ). Head; dark brown, subrectangular or somewhat rectangular, broadest in the middle, length of head to side base of mandibles with 3.24 mm to 3.43 mm, width of head at side base of mandibles with 1.61 mm to 1.76 mm. Antennae; 17 segments, the third segment twice as long as the second, the fourth segment shorter than the third. Mandibles; long and sword-shaped, left mandible with crenulations at the base but the right mandible without crenulations, length of left mandible with 1.87 mm to 2.08 mm. Labrum; dome-shaped with long hairs along the lateral sides, broadest in the anterior half, the tip subtriangular, the hyaline tip triangular, not elongated or sharpened at the tip, a few hairs near the post-clypeus. Pronotum; twice as broad as long, a few short hairs along the anterior margin, the lateral angles distinct, the anterior margin convex and emarginate, the posterior margin moderately emarginate, pronotum length with 1.09 mm to 1.14 mm, pronotum width with 2.02 mm to 2.10 mm. Postmentum; rectangular, the sides almost parallel in the middle and slightly convex near the posterior margin. Mesonotum; narrower than the pronotum, the lateral lobes broadly rounded. Metanotum; slightly wider than the mesonotum.
