Diagnosis
6–7 mm. Overall, a very dark species as compared to its closest congeners. The female is characterised by apically hooked hairs on the labial palpi. The male is characterised by a combination of a black scutum, a pale yellow maculation not reaching antennal sockets on the paraocular areas, and a fine punctation on the clypeus and the terga.
Description/variation
See Tables 2 and 3. The size of the yellow face marks on the lower paraocular area is variable in the female and they may be entirely absent, as described for a specimen from Barcelona (Alonso and María 1908; Mavromoustakis 1949 [1948]). The preoccipital band is narrower than in the other two species, and is mostly 1–2 antennal diameters wide. It reaches the level of the upper compound eye. Scutellum black, sometimes with narrow yellow posterior band. Axillae black.
Seasonal occurrence
The flight period extends from June to July.
Distribution
South-western Europe; found in France, Spain and Portugal (Figure 6).
