Flatmesh Weavers

Oecobiidae, also called disc web spiders, is a family of araneomorph spiders, including about 130 described species. They are small to moderate sized spiders, about 2 to 20 millimetres (0.079 to 0.787 in) long combined head and body length, depending on the species. Larger ones tend to be desert-dwelling. The legs are unusually evenly placed around the prosoma; most other spiders have some legs directed clearly forward and the rest clearly backward, or all forward. The first two pairs of legs of many Oecobiids point forward then curve backwards. This gives a scurrying, wheel-like impression that is characteristic of many Oecobiidae, and is helpful as a rough aid to identification in the field.

Characteristic of the family is the anal gland; it bears a tuft of long hairs. Typical colour patterns range from dark-patterned cream in some smaller species, to a small number of symmetrically placed, conspicuous round light spots (commonly yellow or white) on a background that may be anything from a dull orange colour to black. The carapace is rounded and bears a compact group of six to eight eyes medially situated near the front of its dorsal surface.
