About Harpalus serripes (Quensel, 1806)
Harpalus serripes (Quensel, 1806) has a pair of lateral teeth, with one tooth located on each side. Its mandible is simple; both its setae and tergum are long. First instar egg-bursters of this species have only one tooth, while its femora can have up to 10 setae. Its anal tube measures 0.6 millimetres (0.024 in) in length, which matches the length of its head, and is shorter than its cersi. One female specimen of the species was found in Wallasey sandhills in March 1882.
