Abstract The first fossil cyphophthalmid harvestman, Siro platypedibus new species (Arachnida, Opiliones, Cyphophthalmi), is described from Bitterfeld amber, Sachsen-Anhalt, Germany. The age of this amber is in dispute. Geological studies support a Miocene (20–22 Ma) date for the deposit, but the presence of insect species identical to those in Baltic amber (dated at ca. 35–40 Ma) has led other authors to suggest that the Bitterfeld amber comprises older, redeposited material, contemporary with… 

Fossil harvestmen (Arachnida, Opiliones) from Bitterfeld amber

Bitterfeld material includes the fi rst fossil record of the extant genera Amilenus Martens, 1969 and Lacinius Th orell, 1876 respectively, and support the idea that both ambers sampled a similar terrestrial arthropod fauna: irrespective of any diff erence in age.

The first fossil cyphophthalmid harvestman from Baltic amber

The first fossil cyphophthalmid harvestman from Palaeogene (Eocene) Baltic amber is described and resembles modern North American Siro species more than modern European ones, and can be distinguished principally on its relatively large size and the outline form of the body.

A new genus and species of harvestman from Baltic amber

Two new fossil harvestmen (Arachnida: Opiliones: Phalangiidae) from the Palaeogene (Eocene) Baltic amber are described as Stephanobunus mitovi n. gen. n. sp. These remarkable specimens have a

A harvestman (Arachnida: Opiliones) from the Early Devonian Rhynie cherts, Aberdeenshire, Scotland

This remarkable material is implicitly a crown-groups harvestman and is one of the oldest known crown-group chelicerates, and suggests an extraordinary degree of morphological stasis within the eupnoid line.

On the placement of the Baltic amber harvestman Gonyleptes nemastomoides Koch & Berendt, 1854, with notes on the phylogeny of Cladonychiidae (Opiliones, Laniatores, Travunioidea)

Analysis of the claw morphology of extant cladonychiids suggests a transformation series in which the plesiomorphic condition is present in the eastern Nearctic genera Erebomaster Cope, 1872 and Theromaster Briggs, 1969, while the apomorphic condition (found in Holoscotolemon) is a bipronged, widely forked claw with a short base.

The genus Centrochthonius is diagnosed for the first time since its original description and provides further evidence for significant range shifts and extinction events in the Holarctic invertebrate biota during the Cenozoic.

Baltic amber harvestman types (Arachnida: Opiliones: Eupnoi and Dyspnoi)

The problematic Cheiromachus coriaceus Menge, 1854 is considered a nomen dubium, as is Phalangium succineum Presl, 1822, which may not even be a harvestman and the repository of three other Roewer harvestman types and all of Menge’s types remains uncertain.

Fossils from the mid-Cretaceous Myanmar (Burma) amber include all extant orders of Arachnida, including the earliest representatives of Schizomida, Parasitiformes, and Palpigradi, which concurs with evidence from other Burmese amber biota.

Fleas (Siphonaptera) are Cretaceous, and Evolved with Theria

A molecular phylogenetic study based on a comprehensive taxon sampling of 259 flea taxa, suggesting that Theria (placental mammals and marsupials) represent the most likely ancestral host group of extant Siphonaptera, with marsupial occupying a more important role than previously assumed.

A phylogenetic analysis of the genera of Cyphophthalmi is undertaken by studying 32 morphological characters in 43 species representing all families and most genera, and molecular characters strongly support the monophyly of Troglosironidae + Neogoveidae.

Analysis of relationships among the major lineages of Opiliones using both genitalic and non-genitalic char- acters reaffirms the observation that a given hypothesis of character evolution can be consistent with several phylogenetic hypotheses and that an empirically robust phylogenetic analysis should include more than one character system.

The ecofaunistic comparison of the sciarids and ceratopogonids provides evidence for two geographically separated amber producing forests and is more closely related with respect to their age than indicated by the deposits.

The phylogenetic relationships among the main evolutionary lines of the arachnid order Opiliones were investigated by means of molecular and morphological data sets and the most supported hypothesis suggests that Palpatores are paraphyletic.
