Diagnosis. The species is characterized by its approximately spherical gonostylus with the dorsal mesial margin weakly expanded, an apical tooth arising from a small dorsal lobe; gonocoxite with long setae on the ventral side; hypopygium with a conical setose intercoxal lobe; tegmen triangular, parameral apodeme continuously sclerotized forming a central strip on dorsal side and a finger-like process at the apex.
Description (male). Color. Head, antennae, thorax and abdomen dark brown; palps and hypopygium yellowish-brown; mesonotum brown; legs pale brown; wings fumose.
Head ( Figs 3 View FIGURE 3 D, E). Eye bridge with 3 rows of facets. Prefrons with 12–18 setae. Maxillary palps 3-segmented, basal segment with 1–2 setae; 2nd segment with 7–8 setae; 3rd segment with 6–7 setae. Length/width index of 4th flagellomere: 3.79–3.90.
Thorax. Anterior pronotum with 4–5 setae, episternum 1 with 5–8 setae. Wings ( Fig. 14 View FIGURE 14 B). Wing length 2.83– 2.95 mm, width/length: 0.37. c/w: 0.78–0.80. R1/R: 0.69–0.81. r-m, stM, M1 and M2 bare, CuA1 and CuA2 bare. Legs ( Fig. 3 View FIGURE 3 F). Length of spur/width of foretibia 0.99–1.02. Length of femur/length of metatarsus: foreleg 1.39– 1.42. Length of metatarsus/length of tibia: foreleg 0.55–0.57, hind leg 0.46–0.47. Length of hind tibia/length of thorax 1.26–1.31. Claws toothed.
Hypopygium ( Figs 3 View FIGURE 3 A–C). The gonostylus as long as the gonocoxite. The gonostylus approximately spherical, densely setose on the apicoventral part, dorsal mesial margin weakly expanded, with an apical tooth arising from a small dorsal lobe, three long flagellate setae on the inner side of the gonostylus present. Ventral side of the gonocoxite with long setae. Hypopygium with a conical intercoxal lobe. Tegmen triangular, parameral apodeme continuously sclerotized forming a central strip on dorsal side and a finger-like process at the apex. Aedeagus relatively short. Sternite 10 with 1 seta on each half.
Distribution. China (Tibet, Fig. 16 View FIGURE 16 ).
Remarks. Based on the greatly inflated gonostylus, the new species is similar to M. cylindrata ( Figs 2 View FIGURE 2 A, B). However, the new species can be diagnosed in having its gonostylus more inflated and nearly spherical, and the dorsal medial margin of gonostylus less expanded, while M. cylindrata has the gonostylus ovate and the dorsal medial margin strongly expanded. Furthermore, the tegmen of the new species is triangular and a finger-like process exists at the apex of the central strip, while it is evenly curved towards the top and without the finger-like structure in M. cylindrata .
Etymology. This species is named after its nearly spherical gonostylus, from the Latin adjective globulosus, meaning spherical.
