FIGURE 7 in Miocene divergence for Texoreddellia? An important component of the cave-adapted fauna of Texas and northern Mexico

FIGURE 7. Cave-forming carbonate rocks (gray) of the US and Mexico (modified from Weary and Doctor (2014) and Servicio Geológico Mexicano (2022). Counties (US) and municipalities (MX) where Texoreddellia have been collecte are outlined. The El Sabinal cave (red cross) is located in an isolated carbonate area, surrounded by non-cave forming rocks. It is distant (450 km) from the nearest karstic carbonate areas in western Texas with previously described species of Texoreddellia.
