Parasitic and Phoretic Mites Associated with Neotropical Harvestmen from Trinidad, West Indies
TLDR
Overall, the prevalence of infestation for Neotropical harvestmen from the Caribbean island of Trinidad was 9.9%, with significant interspecific variation in the intensity of mite infestation and significant differences in parasitism of hosts between habitats.
Comparative study of walking and climbing speeds among Neotropical harvestmen from Costa Rica
TLDR
This study compared walking and climbing speeds for five common species from Costa Rica representing the families Cosmetidae, Gonyleptidae, Sclerosomatidae, Cosmet families, and Sclerotidae, finding no significant interspecific differences in climbing speed.
Diversity and Habitat Use of Neotropical Harvestmen (Arachnida: Opiliones) in a Costa Rican Rainforest
TLDR
The analysis of covariance supports the hypothesis that leg length is related to climbing behavior for several species belonging to Eupnoi and Laniatores, and provides the first insights into the diverse assemblage of harvestmen inhabiting a wet forest at La Selva Biological Station, Costa Rica.
The Ecological Significance of Leg Autotomy for Climbing Temperate Species of Harvestmen (Arachnida, Opiliones, Sclerosomatidae)
TLDR
It is inferred that leg autotomy is a common (and effective) evasive tactic used by harvestmen, however, the reduction in walking and climbing speeds resulting from leg loss may also affect habitat selection and may ultimately reduce the survivorship of individuals in future encounters with predators.
SEASONAL VARIATION IN PARASITISM BY LEPTUS MITES (ACARI, ERYTHRAEIDAE) UPON THE HARVESTMAN, LEIOBUNUM FORMOSUM (OPILIONES, SCLEROSOMATIDAE)
TLDR
This study provides the first description of annual and seasonal variation in mite infestation of harvestmen from a population in southeastern Virginia.
The harvestman tarsus and tarsal flexor system with notes on appendicular sensory structures in laniatores
TLDR
The tarsal flexor system is described for the first time based on morphological and ultrastructural examinations of several Neotropical harvestmen (Opiliones: Laniatores) and it is argued that this structure is the result of a large pulley attachment site on the internal surface of the cuticle.
Key to the Species of Cosmetidae (Arachnida, Opiliones) of Central America, with Notes on Penis Morphology and Sexual Dimorphisms
To facilitate identification of harvestmen of the family Cosmetidae in Central America, we developed dichotomous keys that distinguish the 33 known genera and the 133 described species for this
Morphological changes during postembryonic development in two species of neotropical harvestmen (Opiliones, Laniatores, Cranaidae)
Morphological changes during postembryonic development in the Cranaidae are described on the basis of the examination of an incomplete series of larvae, nymphs, and adults of Phareicranaus
When troglomorphism dupes taxonomists: morphology and molecules reveal the first pyramidopid harvestman (Arachnida, Opiliones, Pyramidopidae) from the New World
TLDR
Morphological evidence, including male genitalia morphology, supports the inclusion of J. pecki in the family Pyramidopidae in the New World, raising the question of whether this represents transoceanic dispersal or a relict of an ancient widespread tropical Gondwanan distribution.
Light from dark: A relictual troglobite reveals a broader ancestral distribution for kimulid harvestmen (Opiliones: Laniatores: Kimulidae) in South America
TLDR
The discovery of this relictual troglobite indicates that the Olhos d’Água cave was a stable refugium for this ancient lineage of kimulids and acted as a "museum" of biodiversity, highlighting it as one of the most important hotspots of trogLobite diversity and endemism in the Neotropics.
