Etymology. This species is named after the locality, Denizli, where it was found.

Material examined. Holotype female, three female protonymphs and one larva from litter and soil under Verbascum sp. , 37°22'38"N 29°25'56"E, 1084 m a.s.l., 14 July 2019, Acıpayam district, Denizli province, Turkey, coll. M. Akyol.

Remarks. Neophyllobius denizliensis sp. nov. is similar to N. hispanicus Bolland in that setae e 1 do not reach the margin of dorsum, c 1 reach the base of d 1, pdx do not reach the base of d 1, and same the legs chaetotaxy ( Bolland, 1991). However, it differs from N. hispanicus by the following combination of characters: (1) almost dorsocentral setae longer (pdx 44, c 1 52, d 1 133, e 1 104, f 1 73) in the new species versus (pdx 40, c 1 40, d 1 85, e 1 80, f 1 60 in N. hispanicus ); (2) third seta on femur I the longest seta in the new species, whereas shortest in N. hispanicus ; (3) first and second setae on femur II same in length in the new species oppose to second setae the longest in N. hispanicus ; (4) palp tarsus with ω in the new species, versus without in N. hispanicus ; (5) ratio d 1 / h 1 4.58 in the new species (2.83 in N. hispanicus ).
