Mysid shrimp sequences of the Histone H3 gene from Refugio Cave were only two bp (0.6%) different from Pachón and 34 bp (10.3%) from the Central Sierra de El Abra cave population of Piedras. Sabinos and Tinaja cave populations, also from Central El Abra, had identical sequences (not shown) to Piedras. This suggests Spelaeomysis quinterensis in Refugio Cave belong within the Northern Sierra de El Abra biogeographical zone and closely related to Pachón.
