Remarks. The new species is unique in the genus Neophyllobius by having a single pdx seta, but it does resemble N. turcicus Koç & Ayyildiz, 1996 in having the same lengths of some dorsal setae. However, it also differs from N. turcicus by: (1) setae vi 59, pdx 75 long in new species opposed to vi 73, pdx 57 in N. turcicus, and 2) tarsi I–II with 9(1)-9(1) in N. ostovani whereas 10(1)-10(1) in N. turcicus.

Etymology. This species is named in honor of Prof. Hadi. Ostovan, Head of the Department of Entomology, Islamic Azad University, Science and Research Branch, Fars, Iran.
