At least two Hibolithes species, H. conradi and H. semisulcatus, represented in Jurassic (
Oxfordian and
Tithonian) and possibly Early Cretaceous (Late
Berriasian) zones of
Hungary.[5]
H. shimanskyi, H. orlovi and H. ivanovi from Upper
Callovian-Lower Oxfordian of
Bryansk Oblast and
Saratov Oblast of European
Russia, were described in 1976 by Gustomesov. In 2006, Ippolitov assigned H. shimanskyi as a synonym to H. girardoti due to
sexual dimorphism within this species. Ippolitov also assigned H. orlovi and H. ivanovi as synonyms to H. sangensis for the same reason.[6]
