Members of the Cripavirus genus exhibit the Type I intergenic untranslated region (IGR) internal ribosome entry site (IRES) structure (Jan et al. 2006). The type I IRES is characterized by the presence of a conserved consensus bulge sequence (UGAUCU/UGC), absence of a third stem loop in Pseudoknot I, and the presence of a consensus sequence (UUAC) downstream of stem loop I.
See discussion under family description.
Sequence identity at the amino acid level between the capsid proteins of isolates and strains of a species is above 90%. Note that by this definition, Nilaparvata lugens C virus is a member of species Cricket paralysis virus.
Cripa: derived from the name of the type species of the genus, Cricket paralysis virus
