FIGURE 2 in Asian pheretimoid earthworms in North America north of Mexico: An illustrated key to the genera Amynthas, Metaphire, Pithemera, and Polypheretima (Clitellata: Megascolecidae)
FIGURE 2. Schematic diagrams of cross sections of earthworms showing locations of spermathecal pores in intersegmental furrows. When spermathecal pores are present in a specimen, most pheretimoid earthworms in North America have spermathecal pores that are ventrally (A) or ventrolaterally (B) located. The only except is Amynthas rodericensis, whose spermathecal pores are located dorsally (C).

Fig. 4 Ultrametric tree of the Metaphire formosae species group based on BEAST analysis of five mitochondrial and four nuclear genes under Scenario 2 (95% HPD = 4.0–5.0 Ma for the MRCA of the species group). Under this scenario, the divergence between the Yonagunijima species, M. dunan, and its Taiwanese sister species, M. formosae, was estimated to be 3.36 Ma (95% HPD = 2.31– 4.21 Ma)
