Original type series

Holotype ♀, by original designation ( USNM); paratype ♀ ( USNM). Cushman (1926, p. 4) described the species based on two female specimens, clearly referring to the one collected on 7 September 1916 as ‘the type’, providing a catalogue number for it, and the one collected on Mount Katahdin as ‘the paratype’.

Type locality

United States of America, Maryland, ‘ Cabin John ’.

Host

Unknown.

Male

The first description of a male was provided by Heinrich (1962b, p. 792), who referred to the specimen as the neallotype.

Comments

The two records by Carlson (1979, p. 542) (Arizona and District of Columbia) were not listed in the catalogue by Yu et al. (2016).

Heinrich (1977) acknowledged the possibility that the other Nearctic species of the genus, A. brunnescens Heinrich, 1962b , is simply a subspecies of A. americanus , while treating it as separate.
