Diagnosis.

Small species, male length 4.1–4.2 mm. Ocular commissure longer than 1 / 2 of eye width. Scutellum with 1 / 2 of its length hyaline. Ventral surface of middle trochanter smooth. Hemelytra of brachypterous specimens with claval commissure expanded, hyaline, reaching the anterior margin of membrane; medial longitudinal hyaline stripe very wide, sinuous, with same width from base of hemelytra up to coastal margin in membrane suture; hemelytral process stripe large, 20–30 % of hemelytral length; hemelytral process slightly longer than membrane length (Fig. 9 C View Figure 9 )

Taxonomic notes.

This species can be distinguished from M. chinai Hynes, 1948 , the most similar congener, by the longer posterior hemelytral process and by the absence of a pubescent nodule on the middle trochanter.
