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: Bactroceraallodistincta 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.
