Measurements (mm). N = 3 males, mean (range). Length of body: male 26.87 (25.7–28.1); length of fore wing: male 35.27 (33.8–36.6); width of fore wing: male 11.57 (10.8–12.0); length of head: male 3.37 (3.2–3.6); width of head including eyes: male 6.87 (6.7–7.0); width of pronotum including suprahumeral plates: male 10.80 (9.8–11.5); width of mesonotum: male 8.13 (7.4–8.5).

Diagnosis. Procollina nigrapilosa 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 infuscation between the proximal vein divergence and the distal L-shaped infuscation in P. convexa n. sp., P. mesomaculata n. sp., P. nuevoleonensis n. sp., P. tamaulipasensis n. sp. which are spotted in this new species. The infuscation in the hind wing margin of P. nigrapilosa n. sp. distinguishes P. medea which lacks this infuscation. Procollina queretaroensis can be distinguished by its smaller body size (body length less than 23 mm). The anterior postclypeus extends anteriorly along the midline when viewed from above in P. nicaraguaensis n. sp. but forms a smoothly curved surface with the supra-antennal plates in this new species. The lateral uncus lobes form semicircle when viewed from above, the apex of the uncus is flat when viewed from the side, the rostrum does not reach the middle of sternite I, and the fore femora secondary spine height is barely the thickness of the adpressed primary spine in P. hondurensis n. sp. while the lateral uncus lobes have sides angled medially with a semicirclar apex when viewed from above, the apex of the uncus curves downward when viewed from the side, the rostrum almost reaches the posterior of sternite I, and the fore femora secondary spine height is about twice the thickness of adpressed primary spine in P. nigrapilosa n. sp.

Distribution. The species is known only from the type series collected in Guatemala.
