ABSTRACT Pentastomida, tongue worms, are a taxon of about 130 species of parasites, living exclusively in the respiratory tracts of vertebrates. Three-dimensionally preserved Upper Cambrian larvae already demonstrate a high degree of adaptation to parasitism, striking morphological conservatism, and a high diversification by the Late Cambrian, thereby suggesting a likewise diversified host group. Not least due to their highly modified morphology, the systematic affinities of pentastomids remain… 

Arthropod molecular divergence times and the Cambrian origin of pentastomids

Bayesian phylogenetic and relaxed-clock analyses of molecular data help reconcile apparently contradictory views: a pentastomid-branchiuran grouping is recovered, but this clade is the sister group to other Tetraconata, whereas all other crustaceans form a monophyletic group that is sister to hexapods.

Parasitic Arthropods: A comparative zoological-palaeontological study

A possible case of a giant larva from the Upper Jurassic Solnhofen Lithographic limestones (150 million years old, southern Germany), most likely representing an immature cirripede crustacean (barnacles and their relatives) is reported and possible ecological and physiological mechanisms leading to the appearance of giant larvae in other lineages are discussed.

Branchiura (Crustacea) - Survey of Historical Literature and Taxonomy

This survey aims to give an overview of the most important available historical literature on morphology, and systematics / nomenclature in a chronological order for each of the four genera of Branchiura.

An isolated exopod in uncompressed three-dimensional “Orsten”-type preservation from the Cambrian of Australia represents a new species of Marrellomorpha, Austromarrella klausmuelleri gen. et sp.

A New Early Cambrian Lobopod-Bearing Animal (Murero, Spain) and the Problem of the Ecdysozoan Early Diversification

A new xenusian, Mureropodia apae gen. and sp. nov., is found in the lower Cambrian of the Murero Lagerstatte in the Cadenas Ibericas, NE Spain. In Mureropodia, the lobopod length/body width ratio

The oldest tongue worm: a stem-group pentastomid arthropod from the early middle Cambrian (Wuliuan Stage) of North Greenland (Laurentia)

ABSTRACT Rare phosphatised fragments within small shelly fossil assemblages from the upper Henson Gletscher Formation (Cambrian, Miaolingian Series, Wuliuan Stage) of North Greenland (Laurentia) are

Fossil Constraints on the Timescale of Parasitic Helminth Evolution

This compilation shows that the fossil record of soft-bodied helminths is patchy, but more diverse than commonly assumed, and cautions against models of pure co-divergence where use of host calibrations to constrain divergence time estimates may be considered.

Morphological support for the phylogenetic positioning of Pentastomida and related fossils

The results indicate that Pentastomida is a transitional group between the Arthropoda and some of the Nemathelminth groups such as Nematoda and Nematomorpha.

Gill structure and relationships of the Triassic cycloid crustaceans

It is proposed that the cycloid gills originated, in connection with the body size increase and adaptation to fresh‐water environment, as radially arranged infoldings of the respiratory areas cuticle, with strongly calcified rigid dorsal parts suspended from the carapace.

An exceptionally preserved parasitic arthropod, Heymonsicambria taylori n.sp. (Arthropoda incertae sedis: Pentastomida), from Cambrian – Ordovician boundary beds of Newfoundland, Canada

A three-dimensionally and completely preserved phosphatized microfossil has been found in Cambrian–Ordovician boundary bed limestones of the Green Point Formation at Green Point, western

Pentastomid parasites from the Lower Palaeozoic of Sweden

The fossils clearly document the marine origin of the Pentastomida, and that their specific morphology and parasitic life style were already established in the late Cambrian at a high degree of diversification, long before the terrestrialisation of their present final hosts, the tetrapods.

Cambrian Derivatives of the Early Arthropod Stem Lineage, Pentastomids, Tardigrades and Lobopodians An ‘Orsten’ Perspective

‘Orsten’-type preservation is the phosphatisation of cuticular surfaces without any further deformation and has yielded completely three-dimensional fossils, mainly arthropods at scale of 100 μm—2 mm, implying that the ancestry of Arthropoda lies even further back well in the Pre-Cambrian.

Some observations on the taxonomy and systematics of the pentastomid genus Armillifer (Sambon, 1922) in south east Asian and Australian snakes

By using three diagnostic criteria, namely, hook dimensions, annulus number and the form of the terminal segment, it is shown that A. moniliformis australis from Australasian pythons, previously considered as a race of Heymons (1932), is, in fact, a distinct species.

Phylogenetic position of the Pentastomida and (pan)crustacean relationships

Gen arrangement comparisons strongly support an unforeseen assemblage of pentastomids with maxillopod and cephalocarid crustaceans, to the exclusion of remipedes, branchiopods, malacostracans and hexapods.

On the systematics and life-cycle of the pentastomid genus Kiricephalus Sambon, 1922 with descriptions of three new species

The life-cycles of the Kiricephalus genus are shown to involve three vertebrate hosts, and eggs are only infective to amphibians, saurians or mammals, and snakes are second intermediate and definitive hosts, the final infection being acquired through ophiophagy.

A new species of pentastomid from the nasal passages of the reindeer (Rangifer tarandus) in northern Norway, with speculation about its life-cycle

A new species of pentastomid from the nasal cavities of semidomesticated reindeer (Rangifer tarandus) in northern Norway is described and preliminary data on the prevalence of this parasite indicate that it is predominantly parasitic in first- and second-year animals.

A standardized annulus-counting procedure is used in conjunction with comparative hook data to show that variation stems from the fact that the genus Waddycephalus embraces ten species, three of which infect tree snakes and the remainder infect ground-dwelling snakes.
