Cryptus tuberculatus Gravenhorst, 1829 (Fig. 24)

Cryptus tuberculatus is not well documented in visual sources of the internet, although it is easily recognised by a combination of the following characteristics: fore tibia thickened and wider than fore femur, ovipositor short with an index of 0.6–0.7 and tegulae and scutellum white ( SCHWARZ, 2015). Like several other Cryptus spp. our specimen was feeding on flowering umbellifers (Fig. 24) on an industrial terrain (in the port of Antwerp), suggesting some kind of migrating behaviour and thermophilic preferences.

First report for Belgium; unreported in the Netherlands.
