TL;DR: The social wasps of Australia are described, together with a few from New Guinea which are allied to the Australian ones and contribute to the understanding of their taxonomic position.
Abstract: The social wasps of Australia are described, together with a few from New Guinea which are allied to the Australian ones and contribute to the understanding of their taxonomic position. The larvae and the nesting habits of the wasps are described so far as they are known. Three genera occur in Australia. Vespula with two introduced European species is locally established. Polistes has three subgenera, twelve species (one new) and five subspecies (two new). P. bader from Cocos Keeling and Christmas Is and P. barnbusae, sp. nov., with two subspecies from New Guinea are also dealt with, the latter in an appendix. The genus Ropalidia has been discussed at greater length because its whole classification required revision; six subgenera are now recognized though none requires a new name. The known nesting habits of the genus are briefly reviewed. There are 22 Australian species (14 new) with eight subspecies (two new). Two appendices deal with a key to the species of Ropalidia subgenus Icarelia, including non-Australian ones, and a key to most of the species of subgenus Polistratus.

TL;DR: This study inferred the phylogeny of 18 species currently assigned to this genus based on 160 specimens and six markers and suggested the presence of a tropical and an extra-tropical lineage, and eleven previously unrecognized distinct species-level lineages in Protoparmelia s.l.
Abstract: Species recognition in lichen-forming fungi has been a challenge because of unsettled species concepts, few taxonomically relevant traits, and limitations of traditionally used morphological and chemical characters for identifying closely related species. Here we analyze species diversity in the cosmopolitan genus Protoparmelia s.l. The ~25 described species in this group occur across diverse habitats from the boreal -arctic/alpine to the tropics, but their relationship to each other remains unexplored. In this study, we inferred the phylogeny of 18 species currently assigned to this genus based on 160 specimens and six markers: mtSSU, nuLSU, ITS, RPB1, MCM7, and TSR1. We assessed the circumscription of species-level lineages in Protoparmelia s. str. using two coalescent-based species delimitation methods – BP&P and spedeSTEM. Our results suggest the presence of a tropical and an extra-tropical lineage, and eleven previously unrecognized distinct species-level lineages in Protoparmelia s. str. Several cryptic lineages were discovered as compared to phenotype-based species delimitation. Many of the putative species are supported by geographic evidence.
