AR Comb-footed Spiders


Working list of Comb-footed Spiders (Theridiidae) in Arkansas. Contains 52 species at present. List compiled originally from the Peggy Dorris survey list. A few genera have changed from her original list with the updates. I have used the updated classifications. Some species added from internet sources. The state occurrences are from internet sources mostly as well. Ranges listed which do not include AR are species that appear on the Dorris list despite the listed internet ranges. Underlined species did not appear in the Dorris collections but have either been shown in Arkansas by other sources or are expected from the known ranges despite the absence from the impressive Dorris survey. Spiders listed in more states than about twenty are listed as EXTENSIVE.
