- Patu marplesi
- Samoa Western Samoa
The smallest known spider is Patu marplesi (family Symphytognathidae) of Western Samoa. A male specimen found in moss at approximately 600 m (2000 ft) in Madolelei, Upolu in January 1965 measured 0.43 mm (0.017 in) overall - about the size of a full-stop on this page. The Patu marplesi is believed to be a rare native of Western Samoa. However, it may not actually be rare, but rather that there are just very few people who know how to collect it and secondly how to recognize it. As this species only reaches an adult size of 0.43 mm, there are not many photographs of it. Even if photographed through a microscope, a clear picture is difficult to attain.
