Sonoma tolulae is known from the central portion of the eastern border of Tennessee , across the western tip of North Carolina and into extreme northeastern Georgia . Specimens have been collected from elevations ranging from 425-1755 m . Comments. Specimens have been collected every month from April through October from “leaf litter,” “forest litter,” “Leaf/moss mat litter,” “ Epifagus berlese,” “Forest litter / rotten wood,” “litter under rhododendron and hemlock,” “sawdust & pine litter on periphery of small pile,” and “damp litter”. Author MLF collected one female and two male specimens from rotted wood (decay class V). The holotype described by LeConte is female ( MCZ Type Database 2009 ) and was collected from “Tolulae cataractam Georgiae” ( LeConte 1849 ). Author MLF visited Tallulah Falls in Rabun County, Georgia in the fall of 2007 and the fall of 2008 and collected two male and one female specimens. The aedeagal characters of the two male specimens were identical. Based on the presumed type locality and absence of other species, we concluded that these specimens are conspecific with S. tolulae . Aedeagal characters of Sonoma tolulae are similar to those of S. sokolovi . However, the acute apex of the left paramere and shape of the right paramere (right lateral margin abruptly curved to produce an acute apex with straight outer margin) and the lack of a subapical internal lobe on the apex of the right paramere in S. tolulae will distinguish these two species. Individuals may have either fully formed flight wings, reduced flight wings, or be entirely brachypterous. Individuals with reduced or absent flight wings have no microtrichia on tergite one. A disarticulated specimen of Sonoma chouljenkoi from Black Mountain, Buncombe County, North Carolina was in Orlando Park’s collection labeled Sonoma tolulae . It appeared to be specifically prepared to be used as a model for external morphology illustrations. Park provided several illustrations of “ Sonoma tolulae ” in A Study in Neotropical Pselaphidae (1942) and we suspect that S. chouljenkoi was used as the model. However, the stylized form of the drawings and lack of noticeable differences in the external structures between S. chouljenkoi and S. tolulae resulted in drawings that were not species specific. The only previous illustration of an aedeagus attributed to S. tolulae is in Marsh and Schuster (1962) . The illustration is clearly of S. chouljenkoi and the only additional locality given by them is “Black Mountain, Buncombe County, North Carolina .” They do not say how or from whom they obtained the specimen or illustration, but probably the specimen or illustration came from Orlando Park and is based on a specimen from the same series from which his disarticulated model came. We found no examples of dissected genitalia labeled Sonoma tolulae in Orlando Park’s material.
