Kondratieff & Kirchner (2000) and Stark et al. (2000) used scanning electron microscopy to elucidate fine details and variability of the 8th abdominal process of A. recta . When viewed dorsally this process varies considerably, including button-like and convex ( Kondratieff & Kirchner 2000, Fig. 24), button-like and weaklyincised distally ( Kondratieff & Kirchner 2000, Fig. 26), and trilobed and slightly concave distally ( Stark et al. 2000, Fig. 9). The deeply-incised form shown initially by Alford (1998, Fig. 5) from Mississippi as A. recta was subsequently described as A. starki by Kondratieff & Kirchner (2000) and illustrated in Nations et al. (2007). Fresh material of A. recta collected from the Paint Rock River drainage in northeastern Alabama and southern Tennessee exhibits a dorsal process that is button-like and weakly-incised distally ( Figs. 3A–D ) and very similar to Fig. 26 in Kondratieff & Kirchner (2000).
