Clytius semitincta (Dyar, 1924) is a valid species distinct from Clytius clytius (Godman & Salvin, 1897)

Genomic analysis of two syntypes of Bolla semitincta Dyar, 1924 (type locality in Colima, sequenced as ♂ NVG-15109B06 and ♀ NVG-15109C12) currently regarded as a junior subjective synonym of Clytius clytius (Godman & Salvin, 1897) (type locality in Mexico: Nayarit, Tres Marias Island) reveals that the two taxa are genetically differentiated at the species level ( Fig. 27), e.g., their Fst / Gmin /COI barcode differences are 0.22/0.004/2.1% (14 bp). Hence, we propose that Clytius semitincta (Dyar, 1924) , stat. rest. is a species distinct from Clytius clytius (Godman & Salvin, 1897) . Furthermore, in addition to C. clytius , C. semitincta (Dyar, 1924) , and Clytius unifascia (Mabille, 1889) , comb. nov., stat. rest. (type locality in Honduras), we observe a clade corresponding to a fourth species in the group, from eastern and southern Mexico, that enters the USA in the lower Rio Grande Valley of Texas. This species does not have a name and is described as new below.
