The arachnid order Opiliones has typically been divided into three suborders (Cypho- phthalmi, Laniatores and Palpatores), but this system has been challenged in recent years. Based on scenarios of genitalic evolution, Martens and coworkers have argued that certain lineages within Palpatores are more closely related to Cyphophthalmi than to other palpatorean opilions and erected a new clade, Cyphopalpatores, to accommodate this proposal. However, this system is also problematic. Because most… Expand

A molecular phylogenetic approach to the New Zealand species of Enantiobuninae (Opiliones : Eupnoi : Neopilionidae)
Abstract. Members of the New Zealand Enantiobuninae constitute some of the most charismatic soil arthropods of the archipelago, and a striking example of sexual dimorphism, with nondescript femalesExpand
PHYLOGENETIC ANALYSIS OF PHALANGIDA (ARACHNIDA, OPILIONES) USING TWO NUCLEAR PROTEIN-ENCODING GENES SUPPORTS MONOPHYLY OF PALPATORES
TLDR
Higher relationships within Phalangida are examined using two nuclear protein-encoding genes, elongation factor-1α and RNA polymerase II, from 27 opilion species representing seven superfamilies, and Palpatores is recovered as the monophyletic sister group to Laniatores with moderate to strong empirical support. Expand
A molecular phylogenetic approach to the New Zealand species of Enantiobuninae (Opiliones : Eupnoi : Neopilionidae)
TLDR
The first phylogeny based on molecular data for the New Zealand species in the genera Forsteropsalis, Pantopsalis and Mangatangi is presented, and the taxonomic implications of the results are commented on, including the diagnostic viability of important morphological characters. Expand
A multilocus approach to harvestman (Arachnida: Opiliones) phylogeny with emphasis on biogeography and the systematics of Laniatores
TLDR
Age estimates for the main Opiliones lineages suggest a Carboniferous diversification of Cyphophthalmi, while its sister group, Phalangida, diversified in the Early Devonian, and most major lineages predate the Cretaceous. Expand
A new genus of cyphophthalmid from the Iberian Peninsula with a phylogenetic analysis of the Sironidae (Arachnida : Opiliones : Cyphophthalmi) and a SEM database of external morphology
TLDR
Results suggest that the new genus is sister to Paramiopsalis Juberthie, 1962, although nodal support for this relationship is low, and Phylogenetic analysis is conducted using equal weights and the implied weighting method as a means of testing the stability of clades with respect to parameter variation. Expand
The phylogeny and evolution of the flashiest of the armored harvestmen (Arachnida: Opiliones).
TLDR
There is evidence for one colonization of today's temperate zone early in the history of Gonyleptidae, during the Paleogene, at a time when the Neotropical area extended poleward into regions now considered temperate, providing a possible mechanism for the colonization of the extratropics by a tropical group following the Paleocene-Eocene Thermal Maximum. Expand
A divergent Cardinium found in daddy long-legs (Arachnida: Opiliones).
TLDR
It is concluded that some Opiliones harbor a newly discovered Cardinium clade, a divergent monophyletic clade with strong support that has so far not been found in other arthropods. Expand
The occurrence of two adult instars among Grassatores (Arachnida: Opiliones)—A new type of life-cycle in arachnids
TLDR
It is the goal to formalize the working hypothesis that Grassatores have two (and only two) instars in the adult phase, which is strikingly different from all known arachnids. Expand
Polyphyly of Caddoidea, reinstatement of the family Acropsopilionidae in Dyspnoi, and a revised classification system of Palpatores (Arachnida, Opiliones)
TLDR
A phylogenetic study of minute arachnids from most of the landmasses inhabited by Caddidae and a new phylogenetic proposal for Eupnoi and Dyspnoi is proposed, suggesting that the ancestral Palpatores was probably a tiny harvestman with an enlarged ocularium and glandular palpal setae in its enlarged and armed palps. Expand
Phylogeny and Systematic Position of Opiliones: A Combined Analysis of Chelicerate Relationships Using Morphological and Molecular Data 1
TLDR
The internal phylogeny of the Opiliones is robust to parameter choice and allows the discarding of previous hypotheses of opilionid phylogeny such as the “Cyphopalpatores” or “Palpatores,” and resolution within the Eupnoi, Dysp noi, and Laniatores is also stable to the superfamily level, permitting a new classification system for the opiliones.

  • 1988
TLDR
Cladistic analysis of amino acid sequence data, including evaluation of all equally or almost equally parsimonious cladograms, shows that much homoplasy (parallelisms and reversals) is present and that few or no well supported monophyletic groups of families can be demonstrated. Expand
