Brown Grass Spider
The genus Polyboea comprises only two species of which one is found in Singapore. They are defined principally by the arrangement of the anterior eyes. Unlike Perenethis. the AME are much smaller than the ALE. They are positioned along an imaginary arch with the concavity facing downwards. Compared with Perenethis, they have proportionately longer chelicerae and more spiny legs.
With its spiny legs, P. vulpina appears similar to a lynx spider. but the eye arrangement differs. Furthermore, P. vulpina lacks the tall clypeus typical of an oxyopid.
| Length | ♀ 9 mm; ♂ 8 mm |
| Type Locality | Yangon, Myanmar |
| Distribution | Singapore, Malaysia (Peninsular Malaysia), Thailand, Myanmar (Yangon). |
| Habitat | Amongst grasses and low shrubs, often at forest margins. |
| Biology | Males and females build large three-dimensional webs that may be connected with one another. The web-building habit also helps to distinguish Polyboea from oxyopids which also have spiny legs and are superficially similar to Polyboea. |
