Abstract
We describe six new species of Orthochirus: O. birulai sp. n. (Pakistan), O. formozovi sp. n. (Afghanistan, Iran, Tajikistan, Turkmenistan), O. grosseri sp. n. (Uzbekistan), O. kryzhanovskyi sp. n. (Pakistan), O. nordmanni sp. n. (Afghanistan), and O. sejnai sp. n. (Iran). Descriptions are complemented with color photographs of preserved specimens. The identities of Orthochirus melanurus (Kessler, 1874) (Kazakhstan, Uzbekistan), O. persa (Birula, 1900), stat. n. (Afghanistan, Iran), and O. scrobiculosus (Grube, 1873) (Turkmenistan) are reexamined, based on detailed study of the type specimens; lectotypes of all three species are designated. We demonstrate for the first time that the name O. scrobiculosus, previously used as an ‘umbrella’ for various Orthochirus from Central Asia and the Middle East, is currently applicable only to a few confirmed populations from the southwestern Turkmenistan, near the Caspian Sea. New synonymies are proposed at the species level: Paraorthochirus blandini Lourenço & Vachon, 1997 = Orthochirus fuscipes (Pocock, 1900), syn. n. and Afghanorthochirus erardi Lourenço & Vachon, 1997 = Orthochirus persa (Birula, 1900), stat. n., syn. n. We provide a distribution map and a key to all Orthochirus found in ten Asian countries: Afghanistan, India, Iran, Iraq, Kazakhstan, Pakistan, Tajikistan, Turkey, Turkmenistan, and Uzbekistan (41 species).
