CladeInsulana Etymology. Insulana (Lat.), refers to the insular geographic provenance of taxa in this subgenus. Notes. The specimens in this clade were mostly collected from insular ecosystems of Oceania and Malay Archipelago, such as Australia, New Caledonia, New Zealand, Malaysia and Singapore. According to their distinct geographical distribution and phylogenetic relationship (96 % ML bootstrap, 1.00 BPP) (Fig. 1), clade Insulana was presented to accommodate these specimens, which is consistent with previous findings in Feng et al. 2016, Niskanen et al. 2018 and Sugawara et al. 2022. Due to the lack of researchable specimens, it is currently proposed as a new clade rather than a new subgenus.
