SUBORDER MESOTHELAE These spiders resemble the Solifugae ("wind scorpions" or "sun scorpions") in having segmented plates on their abdomens that create the appearance of the segmented abdomens of these other arachnids. They are both few in number and also limited in geographical range.
SUBORDER OPISTHOTHELAE This suborder contains the spiders that have no plates on their abdomens. It can be somewhat difficult on casual inspection to determine whether the chelicerae of members are of the sort that would put them into the infraorder of the mygalomorphs or the infraorder of the Araneomorphs. The spiders that are called "tarantulas" in English are so large and hairy that inspection of their chelicerae is hardly necessary to categorize one of them as a Mygalomorph. Other, smaller, members of this suborder, however, look little different from the Araneomorphs. (See the picture of the Sphodros rufipes below.) Many Araneomorphs are immediately identifiable as such since they are found on webs designed for the capture of prey or exhibit other habitat choices that eliminate the possibility that they could by Mygalomorphs. Infraorder Mygalomorphae Spiders in this infraorder are characterized by the vertical orientation of their chelicerae and the possession of four book lungs. |
