Novel lures and COI sequences reveal cryptic new species of Bactrocera fruit flies in the Solomon Islands (Diptera, Tephritidae, Dacini)

Results from a snap-shot survey of Dacine fruit flies carried out on three of the Solomon Islands in April 2018 are reported. Using traps baited with the male lures cue-lure, methyl eugenol, and zingerone, 30 of the 48 species previously known to occur in the Solomon Islands were collected. Six species are newly described here: Bactrocera allodistincta sp. nov. , B. geminosimulata sp. nov. , B. kolombangarae sp. nov. , B. quasienochra sp. nov. , B. tsatsiai sp. nov. , and B. vargasi sp. nov. , all authored by Leblanc & Doorenweerd. An illustrated key to the 54 species now known to be present in the country is provided.
