Menemerus brachygnathus is a species of jumping spider in the family Salticidae. It is known in Japanese as the shirohige-haetorigumo (白髭蠅取蜘蛛), meaning "white-bearded jumping spider", in reference to the pale, hair-like setae on its body.
Habitat
This species is commonly found in urban and semi-urban environments. It is often observed on walls, buildings, and other man-made structures, where it actively hunts prey.
Description
Menemerus brachygnathus is mottled brown, providing effective camouflage against surfaces such as stone or concrete. The legs are marked with alternating dark brown and beige bands. The body is covered in fine setae, with lighter markings that give rise to its Japanese name.
Females typically measure 8–10 millimetres (0.31–0.39 in) in length, while males are slightly smaller at 6–9 millimetres (0.24–0.35 in).
Like other jumping spiders, it has large anterior median eyes that provide excellent vision, which it uses to detect and stalk prey.
