Kenk R 1970 (citation)- p 7, 'Hyman (1937a and later papers) indicated the geographic range of Phagocata gracilis as extending from Pennsylvania and Virginia westward to Missouri, while P. woodworthi occupies the New England states, New York and New Jersey. She considered the Delaware River to be the dividing line between the two ranges. Since Hyman's studies, few reliable identifications have been made by later investigators, so that some records of 'Phagocata gracilis' may actually refer to P. woodworthi. On the other hand, no overlapping of the ranges of the two species has been demonstrated, and we may, for the present, assume that the two species are allopatric.' p 9, 'At first glance, the distribution of Phagocata gracilis appears to be rather uneven, the District of Columbia and the state of Virginia showing a great preponderance in the number of habitats of the species. Actually, this uneveness reflects only a difference in the collecting activity in the distribution area. The species will, undoubtedly, be found in a number of additional states as well, such as in Maryland and in the still little-explored southern states.'
