Type data. Ukraine, Cherkasy Province, Kaniv, from Myodes glareolus (Schreber) ( L. silvaticum ); Pakistan, Gilgit-Baltistan, Ghizer District, from Apodemus sp. ( L. pakistanum ).

Remarks. Comparison of L. pakistanum with L. silvaticum shows that these species are identical. The fD given for L. silvaticum by Vercammen-Grandjean and Langston (1976) (followed by Fernandes & Kulkarni 2003) is wrong; really this species has fD = 2H-8-6-6-6-4-…, as well as L. pakistanum , but not 2H-8-6-6-4-4-2. Another difference given by the above authors to support the separation of L. pakistanum concerns the shape of barbs on humeral setae; this is an obvious case of individual variation.
