Type material. Holotype female on slide ELB36/21, as well as 26 paratypes, collected in Montenegro in the village of Zaton near Bijelo Polje by the first author on 1 September 2004.
Etymology. The specific name is derived from the generic name of the host plant on which the mites were found.
Host plant. Mentha piperita L. (Lamiaceae)
Relation to host. Vagrants on the undersurface of leaves.
Differential diagnosis. Leipothrix menthae n. sp. is close to Leipothrix lysimachiae (Hong & Kuang 1989) but it differs in the ornamentation of the prodorsal shield, appearance of the coxigenital area and female genitalia, length of the coxal setae 2a and opisthosomal setae d and e. In L. lysimachiae, the prodorsal shield ornamentation shows that the „ median line is incomplete, only the anterior ¼ is present; two transverse lines join complete admedian lines; submedian lines arc-shaped and incomplete“; coxae smooth, female genital coverflap base with 10–12 longitudinal ribs; coxal setae 2a 30, opisthosomal setae d 54, setae e 9.5. In the new species, „shield ornamentation of median line on anterior ¼ of the shield, admedian lines some longer than median; one submedian line on each side entire, sinuous; coxae ornamented with numerous short lines,“ scorings on female coverflap in two ranks, around 10 in each rank, coxal setae 2a 50 (40–60) long, opisthosomal setae d 26 (26–32) long, setae e 20 (15–20) long. Both species inhabit different host plants. L. lysimachiae lives freely on both surfaces of the leaves of Lysimachia clethroides Duby (Primulaceae), whereas L. menthae n. sp. is a vagrant on the leaf undersurfaces of Mentha piperita L. (Lamiaceae).
