Jun 23, 2023 · A transcriptome-based phylogeny of Coleoptera based on 4818 genes by McKenna et al. supported the monophyly of Scarabaeidae with high support, although taxon sampling was limited to eight taxa. However, in phylogenies based on some subsets of data such as the first and second nucleotide position, monophyly of Scarabaeidae was not recovered, as ...

Bayesian Posterior Assessment
The traditional model selection procedure in phylogenetics focuses on selecting the best model from a set of substitution models using statistical criteria such as AIC, BIC, Bayes factor, etc. However, this procedure does not guarantee that the selected model can be reasonably applied to the data due to factors such as heterogeneous evolutionary rates or selection, which can violate assumptions of the available substitution models. Use of substitution models that do not adequately capture the...
Partition scheme search
In addition to use of BPA as a tool to evaluate data and model performance we also used the program Partition Finder in order to select optimal partition scheme for the analyses. Here we used the program following the manual recommendations, i.e. providing an initial set of partitions and letting the algorithm find the best partitioning scheme. However, we found that this procedure may not necessarily find the best solution (as measured by BIC score). We show that, at least in the present cas...
Trees and analyses
Many of the clades supported by the present phylogeny are consistent with previous phylogenetic treatments of dung beetles [10–13, 19, 21]; and, the present results are also highly congruent with the global morphological phylogeny . This similarity between studies shows that results from different sources tend to converge on an underlying pattern in enlarged datasets. The differences across datasets and ML and BI analyses were insignificant in the context of higher-level relationships. Exc...
Molecules vs. Morphology
The position of “basal Scarabeinae” with Paraphytus, as was initially predicted by morphology [1, 10], is largely congruent with present molecular results. The position of Haroldius as sister to Byrrhidium + Dicranocara + Namakwanus within “basal Scarabaeinae” is surprising but strongly supported (see bootstrap values for the preceding ancestor nodes). The phylogenetic affiliations of Haroldius have long remained enigmatic: preliminary morphological analysis placed it in Onthophagini , wh...
Natural tribal classification for dung beetles is essential to study their diversity, ecology and evolution. Strong polyphyly of some historic tribes found in the present analyses and in previous phylogenies [1, 11–13, 19–22] indicates that the tribal classification as currently defined does not reflect natural units and has to be revised. Systemat...
Tribal concepts
The new limits (sensu novo) for tribes proposed here are based on the present results and are also supported by the findings from several recent molecular phylogenetic analyses [11–13, 19–22] and on the global morphological phylogeny . The traditional concepts for the tribe Dichotomiini, Deltochilini (Canthonini), Coprini and Sisyphini follow . List of genera included in the new concept of each tribe (sensu novo) is given in Table 2. The family-group names follow [32, 33]. The concepts...
Tribal diagnoses
The synapomorphies and diagnostic characters were identified based on the results from the recent global morphological phylogeny and are provided in Figs. 4, 5 and Table 1. That morphological study covers all major dung beetle lineages and thereby is the best source for analyzing evolution of morphological characters in this group. Herein, the term synapomorphy refers exclusively to unambiguous synapomorphies which were identified in morphological phylogeny by parsimony mapping of the...

Dec 13, 2022 · The Scarabaeidae was also recovered in recent molecular studies [19, 20, 49]. However, the Scarabaeidae was not supported by other analyses based on morphological characters [18, 50], multi-locus sequence data [21, 51–53] and single-copy nuclear protein-coding gene data . In the present study, the monophyly of Scarabaeidae was strongly ...

Nov 4, 2023 · The most recent global phylogeny (Tarasov and Dimitrov 2016) provided variable statistical support for 8 tribes and generated redefined generic membership for the other 4 listed in the review of Smith (2006). Further tribes have subsequently been defined based on phylogeny (Tarasov 2017, Davis et al. 2019, Daniel et al. 2020a, Rossini et al. 2022).
The ground-pattern of Scarabaeoidea is reconstructed for the first time on the basis of published phylogenetic analyses and the minimum age of extant scarabaeoid family-group taxa is deduced from the fossil record. Abstract The fossil record of scarab beetles (Coleoptera: Scarabaeoidea) is reviewed and its relevance for the reconstruction of the evolutionary history of the taxon is explored ...
