Diagnosis.

Body brownish black, elytra with yellow patches, each patch surrounded with a black circle. Head longer than wide; lateral sides of head with a tooth-like prolongation in front of mandible; gena elongate, with fine wrinkles and setae; lateral sides behind eyes almost parallel; antenna more than half BL. Pronotal disc with fine punctures; lateral sides constricted behind the middle. Scutellum triangular.

Redescription.

BL = 8.7-9.0 mm, BW = 3.0-3.2 mm. Brown or brownish black, with coppery metallic luster, each elytron with two yellow patches, one patch behind the shoulders slightly transverse, and another near the apex rounded, each surrounded by a black circle.

Head (Figs 4 View Figures 1–4 , 11 View Figures 11–14 , 13 View Figures 11–14 ). HL/HW = 1.1; lateral sides of head with a tooth-like prolongation in front of mandible, gena elongate with fine wrinkles and setae, lateral sides behind eyes almost parallel, then constricted behind gena; vertex smooth, with a shallow longitudinal groove in the middle, apex pointed dorsally before the groove; occipit sparsely punctate, with a shallow longitudinal groove medially; frontal tubercle glabrous, raised; clypeo-frontal area triangular, area near anterior margin raised, disc with punctures and setae; labrum transverse, with 3-5 long setae on both apical angles; antenna filiform, more than half BL, antennomeres 1 and 2 nearly globular and shiny, antennomere 1 twice as long as antennomere 2, antennomeres 3 and 4 pubescent and punctate, length almost equal, antennomeres 5-11 cylindrical, with punctures and pubescence, antennomeres twice as long as wide.

Pronotum. PW/HW = 1.1-1.3, PL/PW = 0.9-1.0; anterior angle protruding, posterior angle not protruding; lateral side constricted just behind the middle; middle region of disc with two rows of fine punctures and a longitudinal fovea; posterior transverse impression distinct; basal transverse groove weak. Scutellum triangular, lateral sides of base with pubescence.

Elytra narrowed posteriorly, EL/EW =1.7; suture angle rounded; humeri protruding, humeral groove shallow; basal impression distinct; punctures in basal impression large, remaining punctures small, apical punctures disappeared, intervals with few fine punctures; scutellar stria composed of 3-6 punctures; epipleura raised, with a single row of small punctures; underside of the hind sutural angles with plectrum.

Mesosternum pubescent, mesosternal process short, narrow, densely pubescent, pointed ventrally. Outer metasternal disc with an oblique setose area, extending from posterior angle to the middle of disc (setae partially fell off in Fig. 14 View Figures 11–14 , but their pores still visible); metepisternum densely pubescent.

Abdominal sternite with dense pubescence and punctures, middle area of sternite less pubescent than both sides, transverse impressions distinct in both lateral areas; the eighth visible abdominal tergite with pars stidens.

Legs slender; tibia with punctures and pubescence; femora with dense setae in dorsal surface, with sparse setae in ventral surface, middle area with a triangular denticle.

Genitalia. Median lobe sclerotized, tubular, curved, median foramen occupying 1/4 length of aedeagus; medial portion slightly broader than basal and apical portion in ventral view (Fig. 17 View Figures 15–20 ); middle of apex truncated in dorsal view (Fig. 20 View Figures 15–20 ); tegmen Y-shaped and weak, basal piece of tegmen triangle and relatively small, lateral lobes slender and combined with second connecting membrane; internal sac membranous, with three sclerotized sclerites, dorsal, median, and ventral sclerites (Fig. 23A-C View Figures 21–23 ).

Distribution.

China (Yunnan), India (Manipur).

Host plant.

This species lived on Smilax ferox Wall. ex Kunth ( Smilacaceae ) according to photos (Figs 25 View Figure 25 , 26 View Figure 26 ) taken by the second author (BWX).

Habitat.

The habitats are shown in Fig. 24 View Figure 24 . It is similar to those of M. yuae sp. nov. in Mêdog, but with some patches of cultivated field.

Remarks.

The specimens from Yunnan, China differ slightly from the type specimen in having: 1) body color brown (brownish black in type); 2) sides behind eyes and outer area of metasternal disc with sparser setae (denser in type); 3) antennomeres 3 and 4 longer (shorter in types); 4) anterior yellow patches more distant from shoulder and each of four patches surrounded by a distinct blackish circle (anterior yellow patches closer to shoulder and patches surrounded by a weak blackish circle in type). These external variations indicate that the specimens from Yunnan might represent another new species, but we only checked two specimens from Yunnan and tentatively treated them as members of M. dohertyi . These new records extend the distribution of M. dohertyi northwards by ca 500 km.

We also compared the differences in the internal sac between M. dohertyi and M. yuae , and they differ significantly in the shape of the dorsal sclerite (Figs 21-23 View Figures 21–23 ). In lateral view, the dorsal sclerite of M. dohertyi is obviously enlarged backwards but M. yuae does not have such a sclerite; in dorsal view, the dorsal sclerite of M. dohertyi is slender and narrowed in the middle, and the sides of the dorsal sclerite of M. yuae are nearly parallel; in ventral view, the horn of the dorsal sclerite of M. yuae is bent downwards, but in M. dohertyi it is bent forwards.
