Macrobdella diplotertia, the Ozark highlands leech, is a species of leech found in the southern United States.

[1][2] M. diplotertia was described in 1975 from Missouri, and has since been recorded from Kansas and Arkansas.

[3][4] It is believed to be the sister taxon to Macrobdella decora.

[5] A diagnostic characteristic is the arrangement of the copulatory gland pores.

The species can grow up to 66 millimetres (2.6 in) long.
