Remarks

Bates (1881a) described H. varians based on a series of males and females from Mexico and Guatemala, and reported on the elytral color (translated from Latin): “Elytra entirely fulvous, or posteriorly black and fulvous anteriorly, or with the humerus fulvous [remaining surface black].”

Martins & Galileo (1992), erected Arixiuna , and separated it from Hemilophus Audinet-Serville, 1835 by the absence of whitish pubescence on sides of the elytra (present in Hemilophus ), and from Cuicirama Martins & Galileo, 1992 by the non orthogonal humerus (orthogonal in Cuicirama ) ( Martins & Galileo 1992). Later, Galileo & Martins (2005) described Hemilocrinitus and separated it from Arixiuna especially by the antennal tubercles close to each other (distant in Arixiuna ).

Hovore (2006) reported the geographical distribution of Arixiuna varians as “eMEX (VC), GUA-CR”, meaning that the geographical distribution of the species is from east Mexico (Veracruz), and from Guatemala to Costa Rica. Swift et al. (2010) reported that the species occurs from Mexico (Veracruz) to Costa Rica (Heredia). Monné (2021) reported the species as present in Mexico (Veracruz), Guatemala, and Costa Rica. We think that the report by Monné is better because, although it is very probable that the species also occurs in Honduras and Nicaragua, there is no evidence.
