During 2001-2003, we collected eight species of scolopendromorph centipedes from 17 counties of Arkansas (AR), seven counties of Oklahoma (OK), and 17 counties of Texas (TX). The following taxa were collected: Cryptops leucopodus (Rafinesque) from Bowie and Cass counties, TX, and Pulaski County, AR; Hemiscolopendra marginata (Say) from Columbia, Garland, Hempstead, Little River, Pike, Polk, and Yell counties, AR, and Cass, Cherokee, Coryell, Houston, Johnson, Kimble, Marion, Nacogdoches, Smith, and Tom Green counties, TX; Scolopocryptops rubiginosus L. Koch from Bowie and Dallas counties, TX; Scolopocryptops sexspinosus (Say) from Clark, Columbia, Conway, Faulkner, Hot Spring, Garland, Miller, Montgomery, Polk, Pope, and Pulaski counties, AR, LeFlore and McCurtain counties, OK, and Marion, Red River, and Rusk counties, TX; Scolopendra hews Girard from Atoka, Major, and McCurtain counties, OK; Scolopendra polymorpha Wood from Woodward County, OK; Theatops posticus (Say) from Montgomery County, AR, Choctaw, Marshall, and McCurtain counties, OK, and Cass, Dallas, Freestone, Hopkins, Houston, Red River, and Titus counties, TX; and Theatops spinicaudus (Wood) from Garland, Hot Spring, Little River, Pike, and Scott counties, AR, and Atoka, Choctaw, and McCurtain counties, OK. Most significantly, our records of S. rubiginosus are well outside its distributional range as depicted in Shelley (2002). A total of 43 new county records is documented, including 14 in Arkansas, nine in Oklahoma, and 20 in Texas.
