Family: Dicistroviridae

Genus: Triatovirus

Distinguishing features

Cricket paralysis virus, Israeli acute paralysis virus, and triatoma virus possess a conserved ternary motif (Asp-Asp-Phe) thought to catalyze the cleavage of VP0 into VP3 and VP4. In triatoma virus, a second identical triad exposed to the capsid interior is present in VP3. This motif is conserved in black queen cell virus, Himetobi P virus, and Plautia stali intestine virus.

Derivation of names

Triato: derived from the name of the type species of the genus, Triatoma virus. 

Species demarcation criteria

Sequence identity at the amino acid level between the capsid proteins of isolates and strains of a species is above 90%.
