A new species and additional record of Terellia Robineau-Desvoidy (Diptera: Tephritidae) from Turkey with a key for the Cerajocera group

Abstract

Genus Terellia Robineau-Desvoidy, 1830 includes approximately 60 species throughout the Palearctic region. Larvae ofTerellia develop in the flowerheads of the family Asteraceae. In this study, the authors collected species of Terellia from possible hostplants in the summer of 2009 and 2017 in northeastern Turkey using an insect net. Collected materials were pinned and deposited inthe Gaziantep University Entomology Laboratory. Upon identification, Terellia (Cerajocera) akguli sp. nov. has been described as a newspecies and placed in the subgenus Cerajocera. Also, T. (C.) armeniaca Korneyev, 1985 has been recorded for the first time in Turkeywith this study. The paper describes new species and presents morphological characteristic figures of the new species. Additionally, thekey for the subgenus Cerajocera distributed in Turkey is provided.
