Smicronyx reichii (Gyllenhal, 1835)
De yellowish larvae develop in the fruits; once full-grown they leave through an opening made in the middle part of the fruit and pupate in the soil (Dieckmann) That they would make stem galls in Gentianella species, as stated by Buhr, is not correct.
Centaurium erythraea, pulchellum.
The species is not mentioned in the Fauna Europa (2014), not in the synonymy either.
