Diagnosis. Measures: Body length 8.5 ± 0.71 mm; width 2.90 ± 0.14 mm; mesonotum 6.25 ± 0.35 (n=3). Body size more than nine millimeters. Frons reddish-brown. Mesonotum entirely black with lateral areas reddish-brown. Scutellum black except marginal areas. Legs black with reddish knees. Wings spotted. Spots in cell r 2+3 connected by diffuse black line. Basal abdominal tergites 1–4 black.

Description. FEMALE. Body length 8.3 mm; width 2.88 mm; mesonotum 4.01. Head. Eye brownish. Several large, black outer vertical setae. Scape, pedicel and flagellum reddish-brown; pedicel longer than scape, with several short and strong black bristles positioned dorsally and on outer face. Flagellum bicolored. Subapical arista blackish brown and basal area 2x wider than the middle. Frons reddish-brown with many black hairs distributed heterogeneously. Ocellar triangle black. Face strongly concave, projected and with yellow color as in Fig. 3 ; covered by a few white and black hairs. Gena and cheeks pale yellow with short, darkish hairs; labrum darkish-brown, Palp light brown and round with black setae. Thorax. Postpronotal lobe reddish-brown with several black postpronotal setae; mesonotum black with several short, thin, black acrostichal setae; spaced dorsocentral setae; notopleuron reddishbrown; scutellum black but sides reddish-brown; five pairs of black marginal scutellar setae; proepisternum brownish-yellow; anterior and posterior spiracles yellow; anterior spiracle with long black setae on the posterior margin; anepisternum, katepisternum, anepimeron, katatergite, anatergite and meron darkish-brown with some black irregular areas ( Fig. 11 ) Legs. Coxa and trochanter blackish-brown; femur, tibia and tarsi black, covered with dense black hairs; tarsi dark brown with several short setae; claws blackish. Wings. Two black spots at level of anterior crossvein; one dark spot surrounding crossvein r-m (see Fig. 2 ); cell r 2+3 with two extra dark spots, one in subapical area joined by a fine diffuse black line to the other spot in apex; another diffuse black line is present above vein R 4+ 5 in the subapical area; one dark spot at the junction of M1 and dm-cu; junction between M4 and dm-cu outer vein surrounded by clouded areas; halter pale white (see Fig. 2 ). Abdomen. Generally black with some tints of dark blue; tergites 1 to 4 entirely black; tergites from 5 to syntergosternite 7+8 brownish-yellow with darker areas; several black hairs thickly cover all tergites, distributed irregularly on the abdominal segments ( Fig. 2 , Fig. 15 ). Female: Sternite 7 brownish and strongly tapering towards base as shown in Fig. 4 c-d; lateral tooth of apical syntergosternite as long as wide ( Figs 13–14 ).

MALE. Unknown.

Intraspecific variability. Atypical spurious vein in posterior margin on crossvein dm-cu is present in a single individual (Holotype). Other specimens lack this vein modification. Color is similar between the specimens of the series.

Etymology. The specific name honors Dr. Francisco Bozinovic, a Chilean physiological ecologist who initially focused on vertebrates as animal models before curiosity about the ecology and evolution of physiological traits and diversity drew him into the life of invertebrates, especially insects. Dr. Bozinovic was our dedicated thesis advisor as well as of many other Ph.D., M.Sc. and undergraduate students.

Distribution. Valparaíso and Metropolitan regions in central Chile, both in foothills of the Coast Range and the Andes, in association with sclerophyllous forest ( Fig. 21 ).

Remarks. Like M. nebulosa sp. nov., this species has spotted wings, suggesting that it could belong to the M. polystigma group ( Stuke & Clements 2008). Spots in cell r 2+3 are connected by a diffuse black line and is a trait unique to M. bozinovici . This species is smaller than M. nebulosa . Vertical outer setae in M. bozinovici are longer and denser than in M. nebulosa . This species lives in sympatry with M. metallica . Its host is unknown.
