Description and phylogenetic position of a new species of Metarthrodes (Opiliones: Gonyleptidae: Caelopyginae) from Bahia, northeastern Brazil

Zoologia (Curitiba), 2013
We describe Metarthrodes oxum sp. nov. from Camacan, state of Bahia, Brazil, the second species of Caelopyginae described from the state, after Metarthrodes xango Pinto-da-Rocha, 2002. Metarthrodes oxum sp. nov.

Do functional traits improve prediction of predation rates for a disparate group of aphid predators? [PDF]

, 2008
Aphid predators are a systematically disparate group of arthropods united on the basis that they consume aphids as part of their diet. In Europe, this group includes Araneae, Opiliones, Heteroptera, chrysopids, Forficulina, syrphid larvae, carabids ...

Alone no more—Integrative taxonomy of New Zealand odd‐clawed spiders challenges the monotypy of Pianoa and Gradungula (Araneae: Gradungulidae)

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
Taxonomic revision of New Zealand Gradungulidae reveals unexpected northern South Island diversity through integrated molecular phylogenetics and targeted field sampling. Two new species formally described — Gradungula kahurangi sp. nov. and Pianoa civis sp. nov. — with revised male genitalia diagnoses for all three New Zealand genera.

Interactions between invasive and native harvestmen

, 2022
Abstract The harvestman Opilio canestrinii arrived in Denmark around 1980 and quickly became a dominant species in urban habitats. This was followed by nearly complete disappearance of the formerly co-dominant Leiobunum gracile . A second invasive species, Dicranopalpus ramosus , arrived in 2007 and is still under population increase. Old

Micro Gondwana: soil and litter mesofauna in the subalpine and alpine of North‐West Nelson, southern New Zealand

New Zealand Journal of Zoology, Volume 52, Issue 5, Page 944-966, December 2025.
ABSTRACT Alpine ecosystems are vulnerable to the warming climate, yet alpine soil mesofauna remains the less studied part of NZ biodiversity. Here we present a survey of soil mesofauna communities of three mountain peaks in the Nelson‐Tasman and Marlborough regions of the South Island of New Zealand.

Harvestmen as predators of bird nestlings

Journal of Arachnology, 2010
Abstract We report the first confirmed cases of harvestmen (Opiliones) feeding upon live vertebrates. In June and July of 2007, in two independent studies of the ecology of Swainson's warblers (Limnothlypis swainsonii Audubon) in Arkansas and North Carolina, we recorded predation of nestlings at two separate nests by harvestmen.

Strength of forest edge effects on litter-dwelling macro-arthropods across Europe is influenced by forest age and edge properties [PDF]

, 2019
International audienceAim: Forests are highly fragmented across Western Europe, making forest edges im ‐portant features in many agricultural landscapes.

Sexual conflict as a constraint on asexual reproduction: an empirical review

Biological Reviews, Volume 100, Issue 6, Page 2681-2706, December 2025.
ABSTRACT Theory predicts that facultatively asexual animals, which can leverage the advantages of both sexual and asexual reproduction, should outcompete obligately sexual and obligately asexual animals. Yet, paradoxically, obligate sexual reproduction predominates in many animal lineages, while the most flexible form of facultative asexuality (i.e ...

A revised dated phylogeny of the arachnid order Opiliones [PDF]

, 2014
Dating the Opiliones tree of life has become an important enterprise for this group of arthropods, due to their ancient origins and important biogeographic implications.
