Material examined. Syntype (female) of Protomyia lapidaria NHMUK In 58813. 15 females, NMB F1496, F1530, F1565, F1600, F2044, F2059, F2060, F2089, F2103, F2131, F2177, F2242, F2287, F2389, F2406. 1 female, Aix-en-Provence FSL 391927. 5 females, EM 70003, 70004, 70005, 70012, 70205 (A 10.95) (Coll. Coquand, stored at FSL).

Localities. Kleinkembs, Aix-en-Provence. The type is from Rott , Germany.

Diagnosis. A rather small Plecia , total length 4.8 – 6.5 mm. Antennal flagellum rather long, 9-segmented. It can be distinguished from Plecia livida on the longer antenna and by the wider wing which is darkened anteriorly.

Redescription. Male unknown.

Female: Total length 4.8 – 6.8 mm (N=14).

Head (fig. 127): Length 0.55 – 0.85 mm (N=8), width 0.74 – 1.12 mm (N=12). Black, rather wide, rounded. Antennal flagellum rather long, cylindrical, 9-segmented. Ocellar triangle prominent.

Thorax: Length 1.5 – 2.1 mm (N=15), width 1.3 – 1.6 mm (N=6). Black. Sulci deep. Haltere brown.

Wing (fig. 126): Length 4.9 – 6.7 mm (N=7), width 2.0 – 3.0 mm (N=5), length/width = 2.17 – 2.47 (N=5). Oval, comparatively broad, anterior margin conspicuously curved. Light brown fumose, anterior part darkened, veins brown throughout. Costa extends almost to apex of M1. Pterostigma brown, does not extend below R1, conspicuous.

R2+3 with a kink in basal fourth, otherwise nearly straight, oblique. Crossvein M-Cu some distance from base of CuA1. Wing vein measurements in Table 2.
