Labium black; labrum, bases of mandibles, genae, anteclypeus and sides of frons pale; postclypeus, middle of frons, and top of head, including antennae, black, except for a pair of short pale stripes between lateral ocelli and bases of antennae; postocular spots absent, pale occipital bar present ( Fig. 4 View FIGURE 4 b); upper border of Rear of head pale, remainder black ( Fig. 3 View FIGURE 3 b). Prothorax black except for a pair of pale stripes on propleura and lower-most margin; synthorax black dorsally with wide pale antehumeral stripe about 1/2 width of mespisternum, sides of synthorax pale except for ventral border ( Fig. 4 View FIGURE 4 b); legs black, pale at base; wings hyaline; pterostigmata brown, braced, covering three cells. S1-2 black dorsally, pale laterally; S2 with black stripe laterally; S3-6 black with pale basal spot and lateral stripe gradually narrowing distally; S7-8 black except for pale basal spot and a pair of ventral narrow stripes (figs. 2a, 2b); S9 black except for a pale latero-ventral spot; S10 black except for pale postero-lateral spot ( Fig. 5 View FIGURE 5 d); bifurcate process longer than 1/2 of S10, apex acute, outer margin inflectional, not smooth, hemline of bifurcate process about 1/2 width of S10 ( Figs. 5 View FIGURE 5 c, 11), foot-like from latero-ventral view ( Fig. 18 View FIGURES 8 – 20 ); caudal appendages black, cerci almost twice as long as S10, paraprocts vestigial ( Figs. 5 View FIGURE 5 d, 11); genital ligula simple, apical lobs bifurcated beyond the base ( Fig. 2 View FIGURE 2 , d & e).

Female. Similar as male by color pattern but slightly shorter in body length and more robust ( Fig. 2 View FIGURE 2 c). S10 wholly black; ending before level of cerci, black except for pale tip ( Fig. 6 View FIGURE 6 a). Pale body color pattern on living female apple-green.

Distribution. Known from northwestern Burma and central Sichuan, China. The nominotypic subspecies occurs principally north of M. t. australe but south of M. yachowensis ( Fig. 7 View FIGURE 7 ). This subspecies is believed by Kalkman (2008) to occur in Kambaiti, NW Burma.
