Numbers
There are 10 species in BugGuide's range (North America north of Mexico)(1).
Identification
(Not all species and genders are shown here.)

Marpissa bina (female):


Marpissa formosa (male, female):


Marpissa grata (male, female):


Marpissa lineata (male, female):


Marpissa obtusa (male, female):


Marpissa pikei (male, female):


Marpissa robusta (male, female):


Marpissa sulcosa (male):
Range
(Species that can be found in Canada are in bold.)

M. bina: southeastern states from Florida north to at least Beaufort, North Carolina.(2)
M. bryantae: known only from the type locality in Texas.(3)
M. dentoides: northeastern USA, inland to about Tennessee.(2)
M. formosa: eastern USA & southeastern Canada.(2)(4)
M. grata: known from Florida, Michigan, Minnesota, & Ontario.(2)(4)
M. lineata: eastern USA & southeastern Canada, but may be displaced by M. sulcosa in Florida and along the southern coast.(2)(4)
M. obtusa: known only from the type localities in Texas.(2)
M. pikei: eastern USA & southeastern Canada.(2)(4)
M. robusta: known only from Arizona & California.(2)
M. sulcosa: apparently restricted to Florida and the coastal region of the southern Atlantic states (GA, SC, NC).(2)
Remarks
M. bina & M. formosa are very similar-looking; they were once thought to be the same species, but Barnes 1958(2) separated them based on differences in genitalia.

M. bryantae & M. pikei look the same in body coloration and have only slight differences in their genitalia, so might just be variations of a single species, according to Logunov(3). It will not be known for sure until more M. bryantae are collected.

M. lineata, M. dentoides and M. sulcosa are similar in coloration(2).
