Description of a new species of Dacus from Sri Lanka, and new country distribution records (Diptera, Tephritidae, Dacinae)

Abstract

A fruit fly survey in the Sinharaja and Knuckles National Parks in Sri Lanka (2016), using traps baited with the male lures methyl eugenol, cue-lure, and zingerone, yielded 21 species of Dacini fruit flies. Of these, three species, viz. Bactrocera amarambalensis Drew, B. dongnaiae Drew & Romig, and B. rubigina (Wang & Zhao), are new country occurrence records, and Dacus (Mellesis) ancoralis Leblanc & Doorenweerd, sp. n. is described as a new species. The Sri Lankan Dacini fruit fly fauna is now comprised of 39 species.
