Dendryphantes Peckham, in part; Simon, 1903, in part, 
nec Dendryphantes C. L. Koch. 
The genus Dendryphantes was based by C. L. Koch, 
(1837) on Aranea pini DeGeer, ( hastatus Clerck), a com- 
mon species in Central Europe. It is strikingly unlike the 
American species that have been placed in that genus. Den- 
dryphantes pini has the cephalic portion of the carapace 
broad and swollen, the quadrangle of eyes plainly wider 
behind than in front, the second row of eyes nearer the first 
than the third row, the p.l.e. not on extreme margin of the 
carapace, pubescence of scales, three pairs of ventral spines 
on the first tibia, basal, median and distal, that are small 
and opposite, palpus with tibia and patella of about equal 
length, tibial apophysis slender, straight and parallel to the 
cymbium, embolus arises on prolateral side about one- 
quarter from the tip of the bulb, a long slender and slightly 
curved spine, almost half the length of the cymbium. 
In 1901, F.O.P. Cambridge described the genus Meta- 
phidippus basing it on the Mexican species mandihulatus 
and suggesting that the small species described by the Peck- 
hams as Dendryphantes belonged to the genus. These have 
the lateral margins of the carapace almost parallel, certainly 
not swollen in the eye area, the quadrangle of eyes is the 
same width in front as behind, or in a few species only 
slightly wider behind, the second row of eyes is midway 
between the first and third rows, the p.l.e. is on the extreme 
margin of the carapace, pubescence of a few hairs, not scales, 
three pairs of ventral spines on the first tibia, restricted to 
the distal half or two-thirds, strong and not opposite, palpus 
with tibial apophysis a short, bent spur, embolus starts from 
the tip of the bulb, usually a broad, flat lobe, with lateral 
margins chitinized and prolonged in points beyond the 
middle area. 
The genotype, mandihulatus has long, porrect mandibles 
in the male. Most of the American species have short, ver- 
tical mandibles in both male and female but the size and 
angle of the mandibles is a variable character among other 
genera of the Salticidse. All eastern species of the genus 
have no spines on the anterior patellae. 
At the same time, F.O.P. Cambridge erected another 
genus, Paraphidippus and suggested that Attus marginatus
