Sibinia is a of seed weevils in the Curculionidae containing at least 20 described . The genus is divided into three subgenera: Sibinia (s. str.), Dichotychius, and Microtychius. Species develop as larvae within seeds of plants, primarily in the families Caryophyllaceae and Plumbaginaceae. The genus has been studied for its potential use in of plants.

Identification

Sibinia can be distinguished from the closely related Tychius by larval morphological characters. are small weevils with the characteristic elongated rostrum typical of Curculionidae. Subgeneric classification relies on adult morphological characters supported by larval traits.

Habitat

Terrestrial environments where plants occur. Larval development occurs entirely within seeds of host plants.

Distribution

Palaearctic region; Americas (subgenus Microtychius); Bulgaria; Australia (S. fastigiata for biocontrol research). Distribution records from GBIF include Denmark, Norway, and Sweden.

Diet

Seeds of plants. Documented host include Caryophyllaceae (five Palaearctic ) and Plumbaginaceae (S. sodalis). Sibinia fastigiata has been investigated for of Mimosa pigra.

Subgeneric classification

Three subgenera recognized: Sibinia (s. str.), Dichotychius Bedel 1885, and Microtychius Casey 1910. Larval characters support this classification, particularly for distinguishing Sibinia s. str. groups.

Parasitoid complex

S. subelliptica in Bulgaria a diverse complex of chalcidoid including Aprostocetus venustus, Baryscapus sp., Eupelmus barai, E. microzonus, Aximopsis augasmae, A. collina, Eurytoma coleophorae, E. coleopterae, Catolaccus crassiceps, Pteromalus ochrocerus, and Exopristus trigonomerus.
