About Talpa aquitania Nicolas, Martinez-Vargas & Hugot, 2017
Taxonomic Naming and Closest Relatives
The Aquitanian mole (scientific name Talpa aquitania Nicolas, Martinez-Vargas & Hugot, 2017) is very similar to the European mole, a species that has a much wider geographic range. It can be clearly distinguished from both the European mole and the Spanish mole (T. occidentalis) by a combination of specific traits.
Eyelid and Eye Structure
The Aquitanian mole has fused eyelids, with its eyes completely covered by a membrane, while the European mole has open eyes.
Body Part Size Comparisons
It also has a significantly larger head, body, and hind legs than the two comparison species, and is heavier in weight.
Morphometric Measurements
Its weight ranges from 72 to 106 g (2.5 to 3.7 oz), head and body length ranges from 142 to 156 mm (5.6 to 6.1 in), and leg length ranges from 20 to 23 mm (0.79 to 0.91 in).
Dental and Genetic Distinctions
Beyond these physical traits, it differs from the two species in the structure of its M2 and M3 molars, and in its cytochrome b gene sequence.
General Distribution Range
The Aquitanian mole's distribution extends from southwestern France to northern Spain.
Loire River Range Boundary
Its main range lies south and west of the Loire River, while the European mole's main range lies north and east of the Loire.
Sympatric Occurrence
The Loire is not a strict distribution barrier, however, as individuals of both species have been found on the opposite side of the river from their main range, so the two species are likely sympatric in some areas.
