Males of M. breviradia sp. nov. are distinguished from those of M. macdonaldi sp. nov. and M. vespera sp. nov. by the following combination of features: narrow face (Fig. 2); right dorsal surstylar lobe with basiventral projection(s) (Figs 11, 12, 13); phallus long, tubular and C-shaped (Fig. 10). Males of M. breviradia sp. nov. are morphologically variable (see “Remarks”), compared to the known material of the other two species, and some specimens can be further distinguished by the following features: hind femur with ventral setae up to 2X femur width; hind tibia with short erect setae on anterior and ventral surfaces; right epandrial lamella elongated with anterior end subconical and strongly projected (Fig. 13). Females of M. breviradia sp. nov. appear to be indistinguishable from those of M. macdonaldi sp. nov. and M. vespera sp. nov. Description. Male (Figs 1–4, 10–15): Body length 1.38–1.62 mm, wing length 1.43–1.67 mm. Head (Figs 1, 2): Largely blue-grey pruinose with dark brown to black ground colour; slightly broader than thorax in dorsal view, ovoid in lateral view; usually slightly broader than high in anterior view, wider in occasional specimens (about 1.3X broader than high); setae mostly black, paler on occiput laterally and on postgena ventrally. Ocellar triangle conspicuous. Vertex with greenish-bronze reflections. Occiput dark, concave on upper median part. Eyes covered with short ommatrichia, slightly longer near ventral margin; medial edge of eye with weak emargination adjacent to antenna; ommatidia of uniform size. Frons over 2X broader than high, widening above. Face narrow, about subequal to width of anterior ocellus at narrowest point in middle. Face and clypeus concolorous, grey pruinose. Clypeus not separated from face, as high as broad, apical margin weakly produced medially. Setae of head well differentiated: 1 pair of inclinate fronto-orbitals well-separated from base of antenna; 1 pair of lateroclinate anterior ocellars; 1 pair of small posterior ocellars; 1 pair of strong inclinate inner verticals (sometimes referred to as postocellars); 2–4 pairs of lateroclinate outer verticals, anterior and posterior pair usually stronger; upper postocular setae short and uniserial, longer and more scattered ventrally; postgena with longer scattered setae around edge of mouth-opening. Antenna entirely brown to dark brown, inserted above middle of head in profile; scape short, funnel-shaped; pedicel subequal in length to scape, spheroidal with subapical circlet of setulae; postpedicel elongate, 2.1–3.2X longer than wide, conical and gradually tapered distally to broader basally and more abruptly narrowed distally, clothed in fine setulae; arista-like stylus 1.2–1.7X length of postpedicel, with minute hairs. Palpus dark brown, short and narrow, slightly over 2X longer than wide, with 1–2 lateral setulae and 1 long preapical seta. Proboscis brown, short, projecting ventrally. Gena narrow. Thorax (Fig. 1): Dorsum pruinose, dull metallic blue-grey with strong greenish-bronze coloration on posterior 2/3–3/4 (including scutellum), to mostly bronze; pleura pruinose, dull metallic blue-grey with light metallic green and bronze reflections; setae black. Mesoscutum moderately arched, prescutellar depression present. Prosternum fused with proepisternum forming precoxal bridge. Proepisternum with a few setulae. Postpronotal lobe distinct with a few small setae. Mesonotum shield-shaped in dorsal view, slightly longer than wide. Acrostichal setae biserial, short, sometimes sparse, not extended onto prescutellar depression; other thoracic setae well differentiated, each side of mesonotum with: 6 dorsocentrals (posteriormost seta stronger), 1 strong presutural supra-alar (posthumeral), 3 postsutural supra-alars, sparse acrostichal-sized setae intermixed with supraalars, 2 strong notopleurals, 1 strong postalar.
