Abstract

A new species of bumble bee-mimicking brood parasitic bee, Tetralonioidella mimetica Orr & Zhu, sp. nov., is described from China. The systematic placement of this species was initially challenging but was resolved using a combination of phylogenomic and COI barcode analyses, which strongly support the new species as a member of the genus Tetralonioidella Strand. Interestingly, the new species mimics the color pattern of both a bumble bee (Bombus Latreille), and its host Habropoda Smith species, a mimicry format previously unknown for bees. A review of the other Tetralonioidella species revealed three additional bee mimics, including two further likely model-host-brood parasite mimicry complexes. To our knowledge, these represent the first documented three-tiered mimetic systems in bees. Several additional taxonomic actions recently became necessary in these and related taxa: Tetralonioidella meghalayensis Dohling & Dey, 2024 is synonymized syn. nov. with Habropoda radoszkowskii (Dalla Torre, 1896) and Varthemapistra Engel, stat. rev. is again synonymized with Habrophorula Lieftinck. Our results also highlight issues with the generic classification of the tribe Melectini as currently used, as Melecta Latreille was found paraphyletic in relation to the remaining melectine genera. As a first step toward resolving this issue, we return the Melecta subgenus Eupavlovskia Popov, stat. rev. to genus level and discuss the ongoing systematic uncertainties regarding melectine taxonomy.
