Highlights•A new and reliable species tree of Tiliquini skinks (bluetongues and relatives)•Patterns of morphological trait evolution are heterogeneous•Nested “bursts” in evolution lead to new phenotypesSummaryAnimal phenotypes evolve and diverge as a result of differing selective pressures and drift. These processes leave unique signatures in patterns of trait evolution, impacting the tempo and mode of morphological macroevolution.

Cranial suture fusion is not simultaneous, nor does it occur to the same degree in each suture (Sánchez-Villagra 2010); some sutures fuse early during ontogeny, while others never fuse. Both fusion and patency (an open suture) are important to the overall functioning of the skull (White et al. 2021). Open sutures primarily function as sites of interstitial bone growth (Opperman 2000) through the action of pluripotent suture mesenchymal stem cells (Zhao et al. 2015, Maruyama et al. 2016).

New footage confirms Hemiceratoides moths to be bird tear-drinking. Bionomics of Hemiceratoides is updated, and its taxonomy revised, with descriptions of Hemiceratoides ornithopotis sp. nov. and H. avimolestum sp. nov., while Cynisca thysbe, type species of Siccyna (= Cynisca), is recombined as H. thysbe comb. nov. (thus Hemiceratoides = Siccyna synon. nov.), whereas another Siccyna, originally Cynisca reichi, is found to be conspecific with Devena atomifera (synon. nov.).

The primary freshwater crab mandibular palp is described as possessing two or three divisions (joints) and its terminal article as being either unbranched (simple) or bilobed. Currently, this provides two important familial characters.

One of the main challenges of culture-independent soil microbiology is distinguishing the microbial community's viable fraction from dead matter. Propidium monoazide (PMA) binds the DNA of dead cells, preventing its amplification. This dye could represent a robust means to overcome the drawbacks of other selective methods, such as RNA-based analyses. We quantified functional genes from viable archaea and bacteria in soil by combining the use of PMA and qPCR.

Allotheria are an extinct group of mammaliaforms that originally comprised multituberculates, to which ‘haramiyidans’ and gondwanatherians were later added. Phylogenetic relationships of allotherians have remained controversial since the first reports of the allotherian fossils in the 1800s. Here we report a new euharamiyidan based on a skeletal specimen from the Jurassic Daohugou phase of the Yanliao Biota, China. The superb specimen preserves impressions of differentiated hairs.

Fossils of allotherians, such as the haramiyidan Thomasia (‘Microlestes’) Plieninger, 1847 and multituberculate Plagiaulax Falconer, 1857, are among the earliest reported Mesozoic mammals. While their dental similarities were recognized long ago, the relationship between ‘haramiyidans’ and multituberculates has been controversial since their discoveries (Owen 1871, Simpson 1928). This is partly due to the fragmentary material known in the two groups, particularly ‘haramiyidans’.
