USA : AR, IA, IL, KS, MO, NE, OK ( DeWalt et al. 2018 ) Remarks. Perlesta cinctipes is distributed from Nebraska south into the Interior Highlands region of Arkansas , Missouri and Oklahoma and east only to western Illinois ( Fig. 11a ; DeWalt et al. 2018 ). All previously published records from Indiana (DeWalt & Grubbs 2011), Kentucky (Tarter et al. 2006, 2015), Ohio ( Stark 2004 , Grubbs et al. 2013 , DeWalt et al. 2016 ), and West Virginia ( Tarter & Nelson 2006 ), either as P. cinctipes or P . I-4 , now refer to P. armitagei sp. nov. (see below). The record of P. cinctipes from Illinois as noted above represents the eastern known extent of this species range ( DeWalt et al. 2001 ).
