A new species and two new records of the genus Leptus (Trombidiformes: Erythraeidae) from Türkiye.

A new species of Leptus, L. baspinarisp. nov., is described and illustrated from larvae collected via pitfall traps (off-host) from Akçaova (Seferler) reservoir, Gökbel mountain, Aydin Province, Türkiye. The new species belongs to phalangii species group and killingtoni species subgroup. Leptus dubius Paoli and L. pouryayevalii Hakimitabar, Saboori & Fadaei are reported for the first time from Türkiye, and L. dubius Paoli is redescribed and illustrated based on Turkish specimens. New metric data are given for L. pouryayevalii. Keys to killingtoni, torresianus, dubius, and hospeticus species subgroups are presented, and definitions of dubius, bogoriacus and pasopaicus species subgroups are corrected. [ABSTRACT FROM AUTHOR]
