Milnesium barbadosense Meyer & Hinton, 2012


Milnesium barbadosense Meyer & Hinton, 2012 

Terra typica: Barbados Island (Central America)

Material examined: Eleven specimens: Cueva El Infierno (25°18′30.95′′N, 100°12′37.85′′W, ca. 1522 m asl), La Camotera, Santiago, Nuevo Leon, Mexico. Moss on pine ( Pinus  sp.), coll. Jose Juan Flores Maldonado, 6

August 2014. One specimen: Mesa del Oso (25°16′17.77′′N, 100°13′41.86′′W, ca. 2181 m asl), Vista Hermosa, Santiago, Nuevo Leon, Mexico. Moss from pine ( Pinus  sp.), coll. Jose Juan Flores Maldonado, 6 August 2014.

Comments: Typical Mil. barbadosense  was reported from the island country of Barbados ( Meyer & Hinton, 2012), but there are also records of Mil. cf. barbadosense  from Sierra Nevada de Santa Marta, Colombia ( Londoño et al. 2015). All Mexican and Colombian specimens have the claw configuration [3 - 3] - [3 - 3]. Meyer & Hinton (2012) described variability in the presence of spurs on secondary branches of claws on specimens from Barbados. It is possible that the hatchling and juvenile specimens of this species have different number of spurs in comparison with adults. Such a phenomenon has been described in Mil. variefidum Morek, Gąsiorek, Stec, Blagden, & Michalczyk, 2016 ( Morek et al. 2016), Mil. tar. tardigradum ( Morek et al. 2018)  and Mil. cassandrae  sp. nov. (present study).
