Podoschistus scutellaris (Desvignes, 1856) (Fig. 59 A–B)

Podoschistus comprises only one European species. It has a striking sculpture on the dorsal half of the temple, consisting of large, uneven, scale-like ridges (Fig. 59B). All tarsal claws have an additional subapical tooth and vein 3rs-m is missing in the fore wing. Its scutellum and metascutellum is marked yellow apically ( OEHLKE, 1965; FITTON et al., 1988; VARGA, 2015). Furthermore, striking are the black hind trochanters (and tarsi), which contrast with the yellowish brown and white front legs (Fig. 59 A). The males have their face yellow. Specimens are often observed on dead wood, searching for their hosts.

First report of the species and the genus for the Netherlands; confirmed in Belgium.
