(find "storyline", equal level of depth of information) Check out if pages are named correctly, eg.: several family pages seem to have names that only apply to a subset of the family. --Sarefo 02:47, 31 July 2006 (UTC) Move pictures from en:Wikipedia to WikiCommons, eg.: Image:Trifasc.jpg Image:Saint Andrews Cross.jpg Image:Il gardenspider stoop.jpg Image:Aeth1a.jpg Image:Newspider.jpg Image:Picta2a.jpg Image:Keys1.jpg Image:Wolf spider 3411.JPG Translate pages from other WPs into English Expand the following articles (and many, many more): Arachnology Determine spider pictures find example species for every spider family check the Spider gallery, upload pictures to the commons if necessary. much, much more, check the Project page If you complete one of these tasks, please remove it from the list and add your achievement to the project log.

[edit] Recent Mesothelae ...

Recent Mesothelae are characterized by the narrow sternum on the ventral side of the prosoma. Several plesiomorphic characters may be added to recognize these spiders: there are tergite plates on the dorsal side and the almost median position of the spinnerets on the ventral side of the opisthosoma. Mesothelae comprise two families, the Liphistiidae and the Heptathelidae. These can easily be distinguished by their sexual organs and the way they construct their burrows: Liphistiides always have fishing lines in front of the entrance, while Heptathelids have not. Therefore, the latter are more difficult to find. Female Liphistiids have an unpaired receptaculum, in Heptathelids it is paired. Male Liphistiids lack a conductor in their palpal organ, while such structure is present in Heptathelids. Before mating the male creates a sound (not audible to men) to cause the female to appear at the trap door. Then mating may take place. Mesothele spiders are distributed in Miyanmar, Siam, the Malayan peninsula and in Sumatra (Liphistidae), in Vietnam, the Eastern provinces of China and Southern Japan (Heptathelidae).

[edit] Myanmar

• Hallo! I found this article with [1]. Please correct the spelling if necessary. Best regards Gangleri · Th · T 12:00, 7 April 2006 (UTC)

[edit] Taxonomy !

The article states that there are 2 families.
The taxobox counts 10 families.
Elsewhere on the Web as well as on WikiSpecies, the family is supposed to include only 1 family!!!!!!!

There is one family still extant, 2 other families are known from fossil records. Where the other 7 names came from I am not sure. I do know that spiders are continually being reclassified. Anyway, I fixed things. Thanks. P0M 02:29, 15 April 2006 (UTC)

[edit] Giant Prehistoric Mesothelae

Wow so the giant mesothalae in the Walking with Monsters wasn't real. That is just stupid and not cool. I always wanted to be familar with a giant prehistoric spider with a legspan up to 2 feet across and with a body size of over 18 inches long., but since there is no giant super-sized spider of that size, that is just disappointing. Hopefully, just hopefully the scientists will find a real giant prehistoric spider out there someday in the near future.Johnny542 03:48, 6 December 2006 (UTC)
