Eriosocia Razowski and Brown, new genus, is described to accommodate Laspeyresia guttifera Meyrick, 1913 (type locality: Paraguay), resulting in the new combination Eriosocia guttifera (Meyrick). Several morphological features contradict its recent assignment to Cydia as well as Grapholitini, and a reassessment of characters suggests that the genus is best placed provisionally in Enarmoniini. Eriosocia is recorded from Central America (Costa Rica, Panama), the Caribbean (Dominica), and South America (Brazil, Colombia, French Guyana, Paraguay, and Venezuela). Larvae of Eriosocia have been reared on numerous occasions in Colombia and Panama from the fruit of Garcinia madruno (Kunth) Hammel (Clusiaceae).
