Abstract:

In various animal species, male sexual dimorphic characters may be used during intrasexual contests as ornaments to attract females, or to hold them before, during, or after copulation. In the well-known harvestman, Phalangium opilio L., 1758, the behavioral functions of these male sexually dimorphic structures have never been studied in detail. Therefore, in addition to a morphometric study, 21 male contests and 43 sexual interactions were analyzed. Our observations revealed that during contests, the male cheliceral horns form a surface by which the contestants use to push each other face-to-

Background/Objectives: Arachnids are a megadiverse arthropod group. The present study investigated the chromosomes of pedipalpid tetrapulmonates (orders Amblypygi, Thelyphonida, Schizomida) and two arachnid orders of uncertain phylogenetic placement, Ricinulei and Solifugae, to reconstruct their karyotype evolution. Except for amblypygids, the cytogenetics of these arachnid orders was almost unknown prior to the present study. Methods: Chromosomes were investigated using methods of standard (Giemsa-stained preparations, banding techniques) and molecular cytogenetics (fluorescence in situ hybri

Abstract:

Subterranean amblypygids, or whip spiders, are important yet understudied components of cave ecosystems, playing key roles as apex predators in these fragile, nutrient-limited environments. Their restricted distributions make them particularly valuable for understanding cave ecosystem dynamics and conservation needs. However, the diversity and distribution of these arachnids in Colombian caves remain poorly documented. This study examines 53 specimens of amblypygids from 12 Colombian caves, and compiles all available literature records to provide an updated list of cave-associated species in C

Abstract:

Male secondary genitalia (pedipalps) are useful characters for species discrimination in most spider families. Although efforts have been made to establish pedipalp sclerite homologies, there are still many inconsistencies in their use. The majority of the morphological characters used to reconstruct the linyphiid phylogeny address male genitalic variation; these inconsistencies may affect the phylogeny and our understanding of linyphiid evolution. Stemonyphantes Menge, 1866, has been hypothesised to be sister to all remaining Linyphiidae. However, despite the basal position of Stemonyphantes,

Abstract:

Many arachnid taxa have evolved unique, highly specialized sensory structures such as antenniform legs in Amblypygi (whip spiders), for instance, or mesosomal pectines in scorpions. Knowledge of the neuroanatomy as well as functional aspects of these sensory organs is rather scarce, especially in comparison to other arthropod clades. In pseudoscorpions, no special sensory structures have been discovered so far. Nevertheless, these animals possess dominant, multifunctional pedipalps, which are good candidates for being the primary sensory appendages. However, only little is known about the anat

Abstract Whip scorpions are an enigmatic group of terrestrial raptorial arachnids that show remarkable mating and courtship behavior in which the male forms a complex spermatophore. While whip spiders (Amblypygi) are relatively well-studied, whip scorpions (Uropygi) are poorly known. The two orders form the Pedipalpi, whip scorpions (Uropygi include Thelyphonida and Schizomida) and whip spiders (Amblypygi). Two major groups have been described based on the mode of sperm transfer that differ in the duration and mode of the typical female–male tandem mating dance. Because comprehensive studies a

This is the first step in a fascinating sexual biology observed in both genera, which is marked by sexual dimorphism – males are tiny compared with females – and usually involves both emasculation and sexual cannibalism.

Abstract:

A catalogue of Chinese species of the genus Euscorpiops Vachon, 1980 is provided. There are 10 species in total, none of them was recorded from China in “Catalog of the Scorpions of the World” (Fet et al., 2000). A new species, E. puerensis sp. nov. from southern Yunnan is described and illustrated. E. puerensis sp. nov. is characterized by having 18 external trichobothria (5 eb, 2 esb, 2 em, 4 est, 5 et), and 10 or 11 ventral trichobothria in the pedipalp patella; chela with a length/ width ratio average of 2.7 on males and females; pedipalp chela fingers on adult females and males scalloped;

Abstract:

A second species in the spider genus Magnopholcomma Wunderlich, 2008 (family Theridiidae Sundevall, 1833) is described based on a male found at Fortescue Bay in Tasman National Park (Tasmania, Australia). The genus differs from all other genera in the family by somatic characters, specifically the large globular clypeal outgrowth. Magnopholcomma adelphus sp. n. differs from M. globulus Wunderlich, 2008 by somatic and genitalic characters, especially the larger clypeal outgrowth, an inconspicuous fovea, pedipalp with longer tibia, median apophysis strongly basally projected and apical lobe of t

Ten of these species occur in Mexico. In the present contribution, Mastigoproctus spinifemoratus, sp. nov., is described based on an adult male and two juveniles from Eastern Nuevo León and Southwestern Tamaulipas, Mexico. It differs from five other species of Mastigoproctus, in which spiniform tubercles are present on the retrolateral surface of the pedipalp femur, in the vent

The aberrations include the following: the irregular distribution of some trichobothria on both pedipalpal chelae

A new monotypic Australian genus in the orb-weaving spider family Araneidae Clerck, 1757 is described, Venomiusgen. nov., with V. tomhardyisp. nov. as type species. Somatically, Venomiusgen. nov. is similar to the typical leaf-curling orb-weaving spiders, such as Phonognatha Simon, 1894 or Leviana Framenau & Kuntner, 2022, due to a similar elongate cylindrical abdomen and colouration; however, the genital morphology of the new genus is very different. Most unusual are the presence of two strong macrosetae on the male pedipalp tibia. Male pedipalp sclerites are complex, with diagnostic char

The pedipalpal sclerites and somatic characters of two similar species, A. moriutii Tanaka, 1985 and A. hokkaidensis Tanaka, 1985, are compared with those of the new species.

Abstract:

Pseudoscorpions reproduce indirectly, transferring a spermatophore deposited on the substrate. In Cheliferoidea, males perform an elaborate ritual involving pedipalps vibrations and a mating ‘dance’ before depositing the spermatophore in the presence of the female. Thus, this study investigated the reproductive behavior and parental care of the neotropical pseudoscorpion Americhernes bethaniae, from populations collected in the Brazilian Cerrado. Pseudoscorpions were collected from live tree trunks and stored in the laboratory for behavioral observations. In the case of A. bethaniae, courtship
