Among the least studied harvestmen are the members of the family Caddidae sensu Shear, , a group of Opiliones with massive eyes and the putative sister group of the remaining Eupnoi. Caddids were originally described as two families, Caddidae and Acropsopilionidae, but these are currently treated as subfamilies of Caddidae. These minute arachnids are rarely collected and present some interesting biogeographical patterns, including a disjunct distribution between East Asia and eastern North… 

A molecular phylogenetic approach to the New Zealand species of Enantiobuninae (Opiliones : Eupnoi : Neopilionidae)

The first phylogeny based on molecular data for the New Zealand species in the genera Forsteropsalis, Pantopsalis and Mangatangi, and comment on the taxonomic implications of the results, including the diagnostic viability of important morphological characters.

A taxonomic key, diagnoses, and geographic distributions are provided for the 24 species of harvestmen that are known from or are likely to occur in Maryland, with many new characteristics, including those that substantially improve the identification of females.

Evolution of a sensory cluster on the legs of Opiliones (Arachnida) informs multi-level phylogenetic relationships

This paper presents a meta-modelling study of the response of the immune system to changes in the environment through the course of repeated exposure to Lamarckian evolution.

Penis morphology in a Burmese amber harvestman

The unique structure of the penis seen here, and the probable lack of diaphanous teeth, present in all other extant non-acropsopilionid Dyspnoi, suggest that H. grimaldii represents a new, extinct family of large-eyed dyspnoid harvestmen, Halithersidae fam.

Two new species of the genus Siro Latreille, 1796 (Opiliones, Cyphophthalmi, Sironidae) in the European fauna

Two new opilionid species from suborder Cyphophthalmi, family Sironidae, Siro franzi Karaman & Raspotnig sp. nov. and Siro ozimeci Karaman sp. nov., from Austria and Croatia respectively, are

A molecular phylogeny of the circum-Antarctic Opiliones family Neopilionidae

This work attempted to investigate the pattern and timing of diversification of Neopilionidae by sampling across the distribution range of the family and sequencing three markers commonly used in Sanger-based approaches, and identified several generic inconsistencies.

The first molecular phylogeny of palpigrades based on specimens collected in different subterranean habitats from Australia, Africa, Europe, South America and North America found monophyly of Palpigradi, Eukoeneniidae and a division of Eukeneniidae into four main clades, three of which include samples from multiple continents.

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.

A cladistic analysis was performed to test the monophyly of Ceratomontia and study its relationship with the South African triaenonychine genera Austromontia Lawrence 1931 and Monomontiarence 1931, suggesting that it is not a monophyletic group.

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.
