Arctosa emertoni

Gertsch, 1934

Emerton's Wolf Spider

Arctosa emertoni is a wolf spider in the Lycosidae, first described by Gertsch in 1934. It occurs in the United States and Canada, with records from Alberta and Manitoba. As a member of the Arctosa, it belongs to a group of wolf spiders often associated with sandy or littoral , though specific habitat details for this species remain limited in available sources.

Identification

Arctosa emertoni can be distinguished from other North American wolf spiders by its placement in the Arctosa, which is characterized by specific arrangements and genitalic structures. The was described by Gertsch in 1934, suggesting it was differentiated from based on subtle morphological features, likely including details of the epigyne in females and pedipalpal structures in males.

Similar Taxa

Arctosa littoralisBoth are North American Arctosa . A. littoralis is well-documented from sandy beaches and riverbanks, and may share preferences with A. emertoni. A. littoralis has distinctive white or pale mottled coloration for camouflage on sand; whether A. emertoni shares this trait is unknown.

Taxonomic Note

The epithet 'emertoni' likely honors the arachnologist James Henry Emerton (1847-1930), known for his work on North American spiders. The original description by Gertsch (1934) would provide the definitive morphological .

Data Limitations

Available sources provide minimal biological information for this . Most detailed accounts of Arctosa and in North America focus on A. littoralis, and it is unclear how much applies to A. emertoni specifically.
