Diversity
12 genera, 152 species

The family Mimetidae contains roughly 200 species divided among 12 genera, of which Mimetus and Ero are the most common. Mimetids are usually yellow and brown and are usually 3 to 7 millimetres (1⁄8 to 1⁄4 in) long. Mimetids can be recognized by the rows of spine-like hairs on their long front legs; the rows consist of a long spine, followed by a series of progressively shorter ones.

Mimetidae usually hunt by picking at the strands on their prey's web to simulate the movements of either a trapped insect or a potential mate. When their prey comes to investigate, they are instead captured and eaten. Some mimetids have been observed to feed on insects as well. The spider-feeding habit presents problems in mating, and little is known about how the males court females to avoid being eaten. However, some male mimetids in the genus Gelanor, found in South America, have enormously long appendages which they use to inseminate females.

Geographic Range

Pirate spiders are found in forests all around the globe, wherein the highest diversity is found in Central and Tropical South America.[1]

Taxonomy

The Mimetidae are sometimes taxonomically grouped in the superfamilies Araneoidea or Palpimanoidea.

Genera

The categorization into subfamilies follows Joel Hallan's Biology Catalog.
