A new species Campsicnemus issykkulensis sp. nov. is described from Kyrgyzstan. It belongs to the C. magius group of species, being similar to C. compeditus Loew, 1857 and C. bagachanovae Grichanov et Volfov, 2009, and differs from these latter mainly in morphology of the male fore tarsus. Описан Campsicnemus issykkulensis sp. nov. из Киргизии. Он относится к группе видов C. magius, очень похож на C. compeditus Loew, 1857 и C. bagachanovae Grichanov et Volfov, 2009, отличаясь от них, главным образом, морфологией передней лапки самца.
