Nematopodius formosus Gravenhorst, 1829

Nematopodius formosus can be distinguished from N. debilis by its white colouration on the pronotum, dorsolaterally. Generally, the nervellus is broken behind the middle, which also distinguishes it from another unreported species (HORSTMANN, 1989). Supposedly the host range seems to be wider than with the abovementioned N. debilis , with older reports also including Coleoptera and Lepidoptera , but this needs further confirmation ( YU et al., 2012).

First report for Belgium; unreported in the Netherlands.
