Parania geniculata (Holmgren, 1857) (Fig. 6 A–B)

One of the rarer findings of this study. Parania spp. have a unique wing venation: the brachial cell and the 2 nd discal cell are separated by a small portion of the vein 1m-cu ( PÉNIGOT 2021, in press; see also Fig. 6 B).

Overall the species is small, with a fore wing length of 4 mm. With the males the frontal part of the head and the clypeus is completely yellow. Its mesosoma and the apical tergites are predominantly black (possibly with yellow markings on the thorax). Its metasoma is red brown (Fig. 6 A). Our finding took place in a small field where flower mixtures had been sown. Some of the known hosts are rare, but Gypsonoma aceriana (Duponchel, 1843) ( Lepidoptera : Tortricidae ) seems to be the most plausible candidate here ( YU et al., 2012).

First report of the species and the genus for Belgium, unconfirmed in the Netherlands.
