Type material examined. Holotype of L. apertum (T-66-147-154, Tdt-847), larva from Cricetulus migratorius (Pallas) , TAJIKISTAN : Gorno-Badakhshan Autonomous Province , 14 August 1967 , coll. N. I. Kudryashova. Type series is deposited in ZMMU . Type data for synonyms. Kyrgyzstan , Naryn Province, Kochkor District, from Alticola argentatus (Severtzov) ( L. sorosi ), Lepus tolai Pallas , Alticola roylei (Gray) , and Cricetulus migratorius (Pallas) ( L. tolaicum ). Remarks. Comparison of L. sorosi and L. tolaicum with L. apertum shows that they are obviously variants of the same species.
