A phylogenetic analysis of Adephaga is presented. It is based on 148 morphological characters of adults and larvae and focussed on a placement of the recently described Meruidae, and the genus‐level phylogeny of the smaller aquatic families Gyrinidae, Haliplidae and Noteridae. We found a sister group relationship between Gyrinidae and the remaining adephagan families, as was found in previous studies using morphology. Haliplidae are either the sister group of Dytiscoidea or the sister group of… Expand
On the phylogeny and evolution of Mesozoic and extant lineages of Adephaga (Coleoptera, Insecta)
TLDR
The relationships of extant and extinct lineages of Adephaga were analysed formally for the first time and possible reasons for the extinction of †Coptoclavidae are the rise of teleost fish and the competition of Gyrinidae and Dytiscidae, which possess efficient defensive glands and larval mandibular sucking channels.

Larval Morphology of Meruidae (Coleoptera: Adephaga) and Its Phylogenetic Implications
TLDR
Meruidae, or comb-clawed cascade beetles, are a recently discovered monotypic family of Adephaga endemic to Venezuela and are hypothesized to have diverged anterior to Amphizoidae, Aspidytidae, Hygrobiidae, and Dytiscidae. Expand
Phylogenomics of the superfamily Dytiscoidea (Coleoptera: Adephaga) with an evaluation of phylogenetic conflict and systematic error.
TLDR
A phylogenomic approach is used to demonstrate that Aspidytidae are indeed monophyletic, as it is inferred this phylogenetic relationship from analyzing nucleotide sequence data filtered for compositional heterogeneity and from analyzing amino-acid sequence data. Expand
Systematic placement of the recently discovered beetle family Meruidae (Coleoptera: Dytiscoidea) based on molecular data
TLDR
DNA sequence data is used to place this enigmatic taxon relative to other aquatic groups in this suborder, and suggests a sister relationship of Meruidae + Noteridae, while parsimony analyses retrieve MeruidAE + Notomicrus (a basal noterid genus), which combined are the sister group of all remaining noteridae. Expand
A genus-level supertree of Adephaga (Coleoptera)
TLDR
A supertree for Adephaga was reconstructed based on 43 independent source trees – including cladograms based on Hennigian and numerical cladistic analyses of morphological and molecular data – and on a backbone taxonomy, making it the most comprehensive phylogenetic estimate yet published for the group. Expand
Monophyly of terrestrial adephagan beetles as indicated by three nuclear genes (Coleoptera: Carabidae and Trachypachidae)
TLDR
Analysis of phylogenetic relationships of these groups using evidence provided by DNA sequences from all four suborders of beetles suggests that Adephaga was ancestrally aquatic with one transition to terrestrial, however, in analyses constrained to disallow changes from aquatic to terrestrial habitat, the phylogenies imply two origins of aquatic habit withinAdephaga. Expand
The phylogeny of Coleopterida (Hexapoda) – morphological characters and molecular phylogenies
TLDR
A large morphological dataset comprising external and internal features of adults and immature stages is presented here and analysed phylogenetically, indicating that a complex feeding apparatus suitable for saprophagy and sporophagy was ancestral in Coleoptera, with secondary reduction in Archostemata and Adephaga. Expand
Molecular phylogeny of the highly disjunct cliff water beetles from South Africa and China (Coleoptera: Aspidytidae)
TLDR
A re-examination of larval characters in the two aspidytid species revealed that the larva of the Chinese species is strikingly similar to that of Amphizoidae, highlighting the need for more data to address dytiscoid phylogenetics, possibly involving a genomic approach. Expand
Is Meru a specialized noterid (Coleoptera, Adephaga)?
TLDR
The placement of Meruidae as a sister group of the remaining Dytiscoidea (including Noteridae) is refuted, but a small set of external features is not sufficient for a reliable placement ofMeruidae. Expand

Phylogenetic analysis of Gyrinidae based on characters of the larval head (Coleoptera: Adephaga)
TLDR
Characters of the head of larvae of Gyrinidae were examined and evaluated phylogenetically and the monophyly of the enhydrine genera + Orectochilini is suggested by the extreme elongation of the cardines. Expand
Phylogenetic analysis of Adephaga (Coleoptera) based on characters of the larval head
TLDR
Characters of the head of adephagan larvae were examined and analysed phylogenetically, and improvement of the hypopharyngeal filter apparatus suggests the monophyly of Anisochaeta. Expand
On the phylogeny of the Dytiscidae (Insecta: Coleoptera) with emphasis on the morphology of the female reproductive system
TLDR
Members of all currently recognized tribes of Dytiscidae are represented except Anisomeriiniini Brinck, Hydronebriini Guignot and Carabhydrini Watts. Expand
The systematic position of Aspidytidae, the diversification of Dytiscoidea (Coleoptera, Adephaga) and the phylogenetic signal of third codon positions
TLDR
There was a significant increase in the diversification rate at the base of the richest families (Noteridae and Dytiscidae), which could be associated with the development of simultaneous stroke and higher swimming performance, although data on the swimming behaviour of some basal groups of Noteridae are incomplete.

Larval Morphology of Meruidae (Coleoptera: Adephaga) and Its Phylogenetic Implications
TLDR
Meruidae, or comb-clawed cascade beetles, are a recently discovered monotypic family of Adephaga endemic to Venezuela and are hypothesized to have diverged anterior to Amphizoidae, Aspidytidae, Hygrobiidae, and Dytiscidae. Expand

Aspidytidae, or cliff water beetles, are a recently discovered family of Adephaga, which have an apparently disjunct distribution in China and South Africa. The larvae of Aspidytidae are describedExpand
On the systematic position of the genus Notomicrus sharp (Hydradephaga, Coleoptera)
TLDR
Characters of the foreleg demonstrate that the noterid genera Pronoterus, Synchortus, Mesonoterus), Renotus, Noterus, Siolius, Hydrocanthus, Canthydrus, Suphisellus, and Suphis form a monophyletic unit and that Pronsoterus is the sister group of the remainder of these genera. Expand

TLDR
External and internal structures of the cerambycoid and triungulin larvae of Micromalthus debilis are described and compared to features found in larvae of other groups of Coleoptera and a cladistic analysis was carried out. Expand
Phylogenetic analysis of larval and adult characters of Adephaga (Coleoptera) using cladistic computer programs
TLDR
The monophyly of Adephaga and of all adephagan families is confirmed and the high number of equally parsimonius trees is largely due to an inconsistent distribution of character states in basal carabid taxa. Expand
