Marpissoida: Marpissinae
The genus Marpissa likely evolved in the Neotropics where other members of its subfamily are most diverse. Extant members of Marpissa itself, however, are most diverse in the Palearctic and in North America. Of the 11 North American species 4 are recorded for Massachusetts. The relatively long and robust
forelegs along with the general body shape give our Marpissa an elongated look. The initial work on North American Marpissa species by the Peckhams was revised by Barnes and later by Logunov. Edwards and other have suggested that additional changes and corrections are likely necessary but to date this work has not been published.
