First reported case of gynandromorphism in the cuckoo bee Epeolus variegatus (Linnaeus) (Hymenoptera: Apidae: Nomadinae)

Gynandromorphs (or gynanders) are aberrant specimens displaying both male and female morphological features (Michez et al., 2009). Gynandromorphy amongst Arthropods is mainly explained by a chromosomic abnormality during fertilisation or ontogenic development (Narita et al., 2010). Reports of gynandromorphs in bees (Anthophila) are relatively numerous, with six of the seven globally recognized bee families including documented specimens (Michez et al., 2009). The parasitic subfamily Nomadinae (Anthophila: Apidae) contains few reported gynandromorphs, with a total of eight specimens of which only one is from the genus *Epeolus* and, more specifically, from the species *Epeolus julliani* Pérez (Schenck, 1871; Tsuneki, 1975; Pérez-Iñigo Mora, 1982; Wolf, 2000; Engel, 2007; Le Féon et al., 2016; Carion et al., 2025).
