We determined the complete nucleotide sequences of the small (S) and medium (M) RNA segments of an orthobunyavirus isolated from mosquitoes in the Yucatan Peninsula of Mexico. A 528-nt region of the large (L) RNA segment was also sequenced. The S RNA segment has greatest nucleotide identity to the homologous region of Cache Valley virus (CVV; 98%) followed by Potosi virus (POTV; 89%) and Northway virus (86%). The M RNA segment has 96% nucleotide identity to the homologous region of POTV, and less than 74% nucleotide identity to the homologous regions of all other orthobunyaviruses for which M segment sequence data are available. The L RNA segment has greatest nucleotide identity to the homologous region of POTV (98%) followed by CVV (82%) and Tensaw virus (77%). These data indicate that the virus, tentatively named Cholul virus (CHLV), is a novel reassortant that acquired its S RNA segment from CVV and its M and L RNA segments from POTV. Phylogenetic data support this conclusion.
