Key to Apheloria species, based on adult males

1a. Gonopod acropodite ρ-shaped ( Fig. 18A ); prefemur with a short, blunt prefemoral process located marginally ( Fig. 18B , pfp)......................................................................................... A. whiteheadi

1b. Gonopod acropodite circular, O-shaped ( Figs 4A , 7A , 8A , 9A , 13A ); prefemur with a long, scythe-like prefemoral process ( Figs 4A , 7A , 8A , 9A , 13A ) pfp)......................................................................... 2

2a. With distinct bend tubercle at prefemur-acropodite junction ( Fig. 4B , 7B , 13B , bt).................................. 3

2b. With acute angle at prefemur-acropodite junction ( Fig. 8B , 9B ), lacking a distinct bend tubercle at junction.............. 5

3a. Gonopod acropodite circular but with elbow ( Fig. 7A , elb)......................................... A. virginiensis

3b. Gonopod acropodite smoothly circular, O-shaped ( Figs 4A , 13A ), lacking elbow................................... 4

4a. Base of gonopod acropodite with a triangular tubercle posteriorly ( Fig. 4B , bt); prefemoral process shorter and broader basally..................................................................................... A. corrugata

4b. Base of gonopod acropodite with small, indistinct rounded tubercle posteriorly ( Fig. 13B , bt); prefemoral process longer and of uniform width basally......................................................................... A. montana

5a. Acropodite gradually tapered to curved acuminate, J-shaped apex ( Fig. 8B ); prefemoral process short....... A. polychroma

5b. Acropodite tapered to L-shaped acuminate apex and abruptly twisted ( Fig.9B ); prefemoral process long A. uwharrie sp. nov.
