Paracorymbia tesserula, a species widespread from the Caucasus region to the Balkan Peninsula and as a rarity penetrating as far as Central Europe (Czechia, Hungary, Poland, Slovakia), has been described from Hungary as Leptura tesserula by Toussaint Charpentier in 1825 [✮]. The classification of this taxon into the genus and subgenus is the subject of controversy among experts, the authors of the portal are inclined to the opinion of Alexander I. Miroshnikov, who assigns it to the genus Paracorymbia and the subgenus Batesiata [✩].

Interestingly, P. tesserula is one of the last longhorn beetles occurring in Central Europe where the biology is virtually unknown. The larva of this beetle has never been collected. Švácha (in: Švácha and Danilevsky, 1988; ❖) reared larvae of this species ex ovo from "rotten beach wood". Therefore, the species might be associated with beach woods where it is also frequently recorded. One of the many theories says that larvae of this species might feed underground on rotting roots of the hosts. But it has never been confirmed. The species reaches its western border in Bohemia. The westernmost locality of P. tesserula known to us is Hradec Králové (East Bohemia, Czech Republic) [✧].

Adults of this beautiful species, active from June to August, are diurnal and anthophilous.
