Material examined: Two specimens and one egg: Arroyo Blanco ( 25°51′35.37′′N , 100°31′42.16′′W , ca. 873 m asl), 1 km SW of La Purisima, Garcia, Nuevo Leon . Mexico . Moss on tree, coll. Miguel Angel Gonzalez Botello, 1 February 2014 . One specimen: Puerto El Gringo ( 25°23′11.38′′N , 100°12′08.10′′W , ca. 1684 m asl ), La Botella , Santiago , Nuevo Leon , Mexico . Moss on tree ( Quercus sp.), coll. Mario Alberto Garcia Aranda , 17 January 2015 . Comments: Our specimens correspond well with the characteristics mentioned by Pilato et al . (2013) . McInnes (1994) mentioned that Ram. oberhaeuseri ( Doyère, 1840 ) has a cosmopolitan distribution but Pilato et al . (2013) reported the need for a revision of the species. Stec et al . (2018), suggested that lack of data to complete the identification, should be indicated by reference as Ram. cf. oberhaeuseri . In Mexico , it was reported in the States of Michoacán and Mexico ( Beasley 1972 ). This is the third record for Mexico and a new record for the State of Nuevo Leon .
