Taxonomy
Order: ARANEAEInfraorder: AraneomorphaeFamily: Salticidae                                                                                 
Comments: Peckhamia may be easily confused with Synageles, but in Peckhamia, the carapace is not as flat, being more convex in the cephalic area, and has a sharp declevity [sic] behind the row III eyes" (1). Most Peckhamia have three pairs of ventral spines on leg I tibia (most Synageles have two pairs). The eye region occupies half of the carapace in Peckhamia and more than half the carapace in Synageles. There are also differences in the genitalia - males of Peckhamia show a spiraled embolus, while Synageles males show an embolus in the form of a "simple straight rod, curved arc, or short spike". The epigynum in Peckhamia females has sclerotized anterior rims in the form of two arcs (lacking in Synageles)
Species Comment: Regarding the four species of Peckhamia: P. seminola - do not have the constricted abdomen. P. picata - constricted abdomen, a conspicuous constriction right behind their rear eyes (the posterior laterals). They also have a pair of white dots between the rear eyes and another pair on the sides of the abdominal constriction. P. scorpionia - Red, black around eyes, first tibiae enlarged. Eyes form a line as wide as the carapace. P. americana - addition (constricted abdomen, ? conspicuous constriction behind rear eyes)
