Measurements (mm). N = 1 male. Length of body: male 25.7; length of fore wing: male 33.4; width of fore wing: male 10.5; length of head: male 3.7; width of head including eyes: male 7.0; width of pronotum including suprahumeral plates: male 9.8; width of mesonotum: male 7.2.

Diagnosis. Procollina nuevoleonensis n. sp. can be distinguished from P. biolleyi , P. obesa , P. ustulata n. sp. and P. webbi n. sp. by the bronzing of the fore wing in these species. Similarly, P. guatemalensis n. sp., P. mayaensis n. sp. and P. ulnamaculata n. sp. can be distinguished by the spots in the fore wing ulnar cells 2 and 3 not found in this new species. Procollina parva n. sp. can be distinguished by its head being as wide or wider than the mesonotum and P. minima n. sp. can be distinguished by its small body size and radiomedial crossvein being highly angled with respect to the radial crossvein. The distal fore wing medial veins lack a spot of infuscation between the proximal vein divergence and the distal L-shaped infuscation in P. hondurensis n. sp., P. medea , P. nicaraguaensis n. sp., P. nigrapilosa n. sp., and P. queretaroensis . The hind wing margin is not infuscated or any infuscation is restricted to distal edge and the base of hind wing apical cell 4 is not infuscated in P. convexa n. sp. and P. mesomaculata n. sp. The infuscation on the fore wing cubitus anterior 2 connects across the medial cell to the infuscation on the divergence of the median vein and median vein 3 + 4 and the lateral uncus lobes form a semicircle to the apex when viewed from above in P. nuevoleonensis n. sp. but the infuscation on the fore wing cubitus anterior 2 is separated from the infuscation on the divergence of the median vein and median vein 3 + 4 and the lateral uncus lobes form a triangle to apex when viewed from above in P. tamaulipasensis n. sp.

Distribution. The species is known only from the holotype collected in the state of Nuevo Leon in northern Mexico. This is the most northern distribution of all known Procollina species.
