(Fig. 49, 160 – 161)

Plecia rhenana Heyden & Heyden, 1865:

Plecia robusta Brongniart, 1879 (date taken from specimen label)—presumably an unpublished cabinet name in collection of EM

Material examined. Holotype of Plecia rhenana (female) NHMUK In 38798.

Fig. 161. Female, head and thorax. NHMUK In 38798.

Additional material: 4 females, Coll. Coquand, EM: EM 70007, 70016, 70018, 70206 (A 10.14).

Localities. Aix-en-Provence (Rott)

The species was described from Rott, Germany. It is seemingly not present in the material from Aix in MNHN, but there are four females in Coll. Coquand, EM (temporarily stored at FSL) which are probably conspecific with the holotype.
