Astatumen trinacriae ( Arcidiacono, 1962)

Terra typica: Italy (Europe).

Material examined: 27 specimens: 1.2 km E of La Peñita (25°20′44.31′′N, 100°22′05.22′′W, ca. 2370 m asl), Santiago, Nuevo Leon, Mexico. Moss on soil, coll. Mario Alberto Garcia Aranda, 9 February 2015 . One specimen: 7 km E of Agua de los Frijoles (28°57’ 42.952”N, 102°34’ 43.228”W, ca. 2263 m asl), Sierra Maderas del Carmen, Ocampo, Coahuila, Mexico. Moss on tree ( Quercus sp.) coll. Jonas A. Delgadillo Villalobos, 19 December 2016 .

Comments: Our specimens correspond well with the definition of this species proposed by Dastych (1988). Astatumen trinacriae has a mainly Holarctic distribution ( Kaczmarek et al. 2014; McInnes 1994) but can be confused with Ast. bartosi ( Węglarska, 1959) ( Zawierucha et al. 2014) . This is a new record for Mexico.
