Description

Female are about four millimeters long, males slightly smaller. They are similar to the jumping spider Leptorchestes berolinensis, but feature a white line on the back of their heads.[1]

Effect of mimicry
posing S. venator

These spiders are virtually indistinguishable from ants, even for humans looking at them rather closely. They move rapidly like an ant, and even raise their second pair of legs like an ant's antennae. Hand-raised tits that had never come in contact with ants ate spiders of this species readily. However, after their first encounters with real ants, and the nauseating effect of their formic acid, they refrained from eating S. venator.[1]
