Description (holotype): Length 14.0 mm, greatest width 8.5 mm. Deep metallic-green above, dark reddish-brown below; legs dark reddish-brown, with tarsi more infuscated; antennae reddish-testaceous; pilosity pale.
Clypeus almost rectangular, with anterior angles broadly rounded; anterior margin straight, clearly raised. Frontoclypeal suture distinct. Clypeus coarsely, rugosely punctate; anterior part of frons less rugosely punctate, punctures becoming much sparser toward the vertex, with minute not dense punctures between them. Rather long sparse hairs along inner margin of eye. Pronotum 2.5 times broader than long, sides almost parallel in basal half, distinctly convergent in anterior half; anterior angles produced, sharp; posterior angles straight, shortly rounded. Anterior margin weakly bisinuate, with marginal line in lateral thirds; posterior margin of prono- tum considerably convex at middle part, straightened laterally; posterior margin of pronotum with narrow marginal line in lateral thirds. No traces of medial pronotal sulcus. Sides of pronotum with few long erect distant hairs. Pronotum finely and sparsely punctured, with minute sparse punctures between punctures, discernible under high magnification. Scutellum similarly but somewhat more finely and much more unevenly punctured, distal margin ogival. Elytra distinctly convex, sides somewhat broadened posteriad. Elytra finely and moderately densely punctured, with minute punctures between the larger ones; punctate rows hardly discernible. Sides of elytra with marginal line, with elytral epipleura thickened and bearing a row of short and sparse setae. Pygidium moderately convex, finely and very unevenly punctured, with punctures becoming much denser toward the laterobasal angles but very sparse and uneven on disc; minute punctures between the larger ones hardly discernible; pygidium glabrous except for a row of long erect hairs along apical border.
Prosternal process well-developed, plough-shaped, pointed anteriorly. Mesometasternal process very short and bulging. Sides of sterna rugosely punctate and setose, with rather long but not dense adpressed hairs; disc of metasternum glabrous, impressed. Abdominal sternites with a transverse row of rather long but sparse adpressed setae along mid-length; last visible sternite with a transverse row of much longer semi-erect hairs along distal border, the latter somewhat thickened.
Protibia bidentate, teeth widely spaced, basal tooth small; inner spur attached slightly behind the level of basal tooth; fore tarsi attached at level of mid-length of space between protibial teeth. Last joint of fore tarsi thickened, strongly toothed just behind mid-length of its concave margin. Inner fore claw broadened, with lobes slightly divergent, lower lobe about 3 times broader than upper at base. Outer claw of middle tarsi cleft.
Aedeagus: Figs 36–38 View Figs 29–43 .
Female: Length 17.5 mm, greatest width 8.5 mm. Antennal club shorter. Body somewhat more elongated than in male. Side margin of elytra the same as in the male, not callose. Apical tooth of protibia much longer and broader. Inner spur attached well behind basal tooth of protibia, longer than in male. Fore tarsi attached at level of basal tooth. Last joint of fore tarsi weakly thickened, indented just behind mid-length of its concave margin; inner claw narrower, with lower lobe about 2 times broader than the upper one at base. Vaginal palpi oblong and rather narrow, rounded at tip, setose.
Variations: Length 13.5–15.0 mm, greatest width 7.5–8.5 mm (males), 16.0–17.0 mm and 8.0– 8.5 mm (females). Pronotum 2.0–2.5 times broader than long. Expression of punctate rows of elytra slightly varies from specimen to specimen. In worn specimens dorsal punctation seems to be finer and intermixed minute punctures may be hardly visible.
Differential diagnosis: This species is a very close relative of M. rectangular LIN, 1990 (figs 39, 40) known from North Vietnam, northern Thailand, Laos and Yunnan. It differs from M. rectangular as follows: sculpture of frons and clypeus less rugose; the pronotum finely and scantily punctured (vs. coarsely and densely punctured) always lacking middle sulcus; sides of pronotum not margined by yellow; clypeus always entirely green (at least apical half of clypeus is yellow in M. rectangular ); parameres longer and narrower, with their ventral margin not thickened; basal plate with slightly shorter and broader recurved tip.
Distribution: So far known only from the Dalat Plateau, southern Vietnam.
Etymology: The species epithet is formed by the Latin adjective “ germanus, - a, - um ”, meaning “brotherly”, in allusion to the close relations to M. rectangular .
