Contribution to the taxonomy of the Oecetis (Oecetis) tripunctata (Fabricius, 1793) species group (Trichoptera: Leptoceridae)

Abstract

Unsettled, dubious Oecetis tripunctata taxa are studied applying the principles and practices of fine phenomics relying on the ventral profile of the gonopods and the lateral profile of the phallic organ. The distribution of Oecetis tripunctata (Fabricius, 1793) is restricted to the Palaearctic Faunal Region. 14 new species were described from the Oriental Faunal Region: Oecetis anhua s. nov., O. baneswara sp. nov., O. baoloca sp. nov., O. bhubaneswa sp. nov., O. dagna sp. nov., O. dhaulia sp. nov., O. gujara sp. nov., O. halonga sp. nov., O. hoabinha sp. nov., O. kamba sp. nov., O. orissa sp. nov., O. peraka sp. nov., O. prenna sp. nov., O. sabarma sp. nov. and one species Oecetis lata Johanson, Pham, Malm & Sjöberg, 2020 was recorded from Vietnam. 2 new species were described from Australasian Faunal Region: O. kokopa sp. nov., O. parom sp. nov. as new records of the Oecetis tripunctata species group. 10 new species were described from the Afrotropical Faunal Region, including mailand Africa and Madagascar: O. anka sp. nov., O. banda sp. nov., O. bua sp. nov., O. conga sp. nov., O. congana sp. nov., O. ghana sp. nov., O. manta sp. nov., O. maroa sp. nov., O. volta sp. nov., O. zoa sp. nov., and one species Oecetis kagerana Kimmins, 1956 was recorded from Ghana, as well as O. maculipennis Ulmer, 1922 was placed to the Oecetis tripunctata species group. This replacement has necessitated revising and renaming the Oecetis maculipennis species group describing 2 new species: O. kimminsiana sp. nov. and O. nkwanta sp. nov. Oecetis maculipennis species group was renamed as Oecetis kimminsiana species group.
