Abstract In this study we reconstructed the molecular phylogeny and attempted to infer historical biogeography of a sample of cricket species, most of them cave-dwelling, belonging to the subfamily Macropathinae (Orthoptera, Rhaphidophoridae) which shows a clear Gondwanan distribution. We sequenced fragments of 4 genes (12S rRNA, 16S rRNA, 18S rRNA and 28S rRNA), for a total of 1993 bp. We present here preliminary data based on a total of 17 species, 11 belonging to Macropathinae and… 

Phylogeny and phylogeography of Diestramima cave crickets (Orthoptera: Rhaphidophoridae): speciation driven by multiple dispersal and vicariance events

TLDR
Divergence time estimation and reconstruction of ancestral areas indicated that Diestramima may have originated from Southern Yunnan at 17.72 Ma, possibly driven by multiple dispersal and vicariance events and influenced by the uplift of the Himalaya–Tibetan plateau and climate change.

Phylogeography of Troglophilus (Orthoptera: Troglophilinae) based on Anatolian members of the genus: radiation of an old lineage following the Messinian

TLDR
The phylogeography of the genus Troglophilus is addressed, with a special emphasis on its Anatolian members, aiming to test the biogeographical patterns suggested for this area using mitochondrial [cytochome oxidase I (COI)] and nuclear (ITS1-5.8S–ITS2) markers.

Molecular divergence and evolutionary relationships among Aemodogryllinae from Southern China, Laos and Thailand (Orthoptera, Rhaphidophoridae)

TLDR
The data do not support Diestram mena as monophyletic while representatives of Paradiestrammena, Eutachycines and Paratachycine were clustered together, and the validity of some nominal species was confirmed molecularly but they also revealed a large number of deeply divergent lineages.

A Comprehensive Phylogeny of Tettigoniidae (Orthoptera: Ensifera) Reveals Extensive Ecomorph Convergence and Widespread Taxonomic Incongruence

TLDR
The first comprehensive phylogenetic analysis of katydid taxa based on five molecular markers based on 18S rDNA, 28S r DNA, cytochrome c oxidase II, wingless, and histone 3 is presented, finding that the subfamilies Zaprochilinae, Saginaes, Pterochrozinae and Lipotactinae are monophyletic while Meconematinae is paraphyletic.

High alpine sorcerers: revision of the cave wētā genus Pharmacus Pictet & de Saussure (Orthoptera: Rhaphidophoridae: Macropathinae), with the description of six new species and three new subspecies

TLDR
The status and appearance of all known species of Pharmacus are clarified and it is determined that the species Pharmacus brewsterensis Richards, 1972 is better placed within the genus Notoplectron Richards, 1964.

The genus Troglophilus Krauss, 1879 (Orthoptera: Rhaphidophoridae) in the west Balkans

TLDR
The distribution pattern of the western Balkan species supports a general east−west migration route and the centres of origin and spreading directions of particular species are determined according to the distribution of the taxa and the structure of the haplotypes.

Ayersacarus, an endemic mite genus from Zealandian seabird nest environments: revision, with four new species (Acari: Mesostigmata: Leptolaelapidae)

TLDR
Four new species of Ayersacarus Hunter (Acari: Mesostigmata: Leptolaelapidae) are described and this restores Hunter's original 1964 conception of the genus and leaves Ayesacarus with nine species confined to Zealandia.

The thorax of the cave cricket Troglophilus neglectus: anatomical adaptations in an ancient wingless insect lineage (Orthoptera: Rhaphidophoridae)

TLDR
The first detailed investigation and description of the thoracic skeletal and muscular anatomy of the East Mediterranean cave cricket Troglophilus neglectus is presented and a closer relationship of Rhaphidophoridae to Tettigoniidae rather than to Gryllidae is favored.

Genetic structure of populations and species of Dolichopoda cave crickets: evidence of peripatric divergence

TLDR
Multivariate analyses of allele frequency data (PCA and TRGRPS) suggest that geography rather than morphology is the main factor explaining the distribution of the laetitiae-geniculata populations on the scatter diagrams.

Relaxed Molecular Clock Provides Evidence for Long-Distance Dispersal of Nothofagus (Southern Beech)

TLDR
Analysis of a 7.2-kb fragment of the chloroplast genome provides the first unequivocal molecular clock evidence that, whilst some Nothofagus transoceanic distributions are consistent with vicariance, trans-Tasman Sea distributions can only be explained by long-distance dispersal.

Diversification of New Zealand weta (Orthoptera: Ensifera: Anostostomatidae) and their relationships in Australasia

TLDR
Molecular dating approaches are used to test the plausibility of alternative biogeographic hypotheses for the origin of the New Zealand anostostomatid fauna and found support for divergence of the main clades at, or shortly after, Gondwanan break-up, and dispersal across the Tasman much more recently.

Evolution and biogeography of Lyallia and Hectorella (Portulacaceae), geographically isolated sisters from the Southern Hemisphere

TLDR
A phylogenetic analysis of trnK/matK intergenic spacer and rbcL sequences provides evidence supporting a close relationship between Lyallia and Hectorella, which form a well-supported clade that is nested within the Portulacaceae.

MOLECULAR EVOLUTIONARY DIVERGENCE AMONG NORTH AMERICAN CAVE CRICKETS.

TLDR
It is concluded that these insects are among the fastest evolving (with respect to single-copy DNA) groups yet studied-at least as fast as Drosophila and sea urchins-where a ATm of 1?C indicates 0.5 to 1.5 MY since the last common ancestor.

First molecular evidence for the existence of a Tardigrada + Arthropoda clade.

TLDR
The results obtained represent the first molecular evidence for a Tardigrada + Arthropoda clade and indicate the need to review those obtained solely on morphological characters.
