Kar et al. (2010) instituted Ceratohirudispora from the Bhuban Formation (Early Miocene, 23–16 mya) of Tlangsam, Mizoram, India with the following diagnosis “Hyphomycetaceous fungi, conidiophore small, growth terminated by production of apical conidium; conidium enlarges laterally in opposite direction to produce two–three arms, conidia 5–10 celled, septa up to 2 μm thick, with broad base and narrow tip.” Conidia of C. miocenica Kar et al. 2010 (Type) is two-armed and V-shaped (Fig. 1a) whereas the same of C. triradiata Kar et al. 2010 is three-armed and triradiate (Fig. 1b). The nature of the spores (Figs 1a,b) indicate that they are two sperate genera.

Type species: Ceratohirudispora miocenica R. Kar, Mand. & R.K. Kar.
