The fossil record of whip spiders: the past of Amblypygi | PalZ
2021年3月31日 · Whip spiders (Amblypygi), as their name suggests, resemble spiders (Araneae) in some aspects, but differ from them by their heart-shaped (prosomal) dorsal shield, their prominent grasping pedipalps, and their subsequent elongate pair of feeler appendages.
Rediscovery of a Relict Unlocks the First Global Phylogeny of Whip ...
2024年5月11日 · A combination of Oriental, African and Neotropical (OAN) regions was optimized as the most likely ancestral area of Amblypygi, as well as for Euamblypygi. Exclusion of the jump parameter rendered the inclusion of the Mediterranean region to the OAN regions as the ancestral area for Amblypygi (Supplementary Fig. S4).
Amblypygi - an overview | ScienceDirect Topics
Amblypygi (whipspiders), Uropygi (whipscorpions or vinegaroons), Schizomida (no common name), and Palpigradi (micro-whipscorpions) are all small, unfamiliar arachnid groups that are closely related to each other and to spiders (Fig. 2). Like primitive spiders, all have two pairs of abdominal book lungs, although the second pair is missing in ...
Amblypygi - Wikipedia
Amblypygi is an order of arachnids also known as whip spiders or tailless whip scorpions, not to be confused with whip scorpions or vinegaroons that belong to the related order Thelyphonida. The name "amblypygid" means "blunt tail", a reference to a lack of the flagellum that is otherwise seen in whip scorpions.
The kinematics of amblypygid (Arachnida) pedipalps during …
2024年2月27日 · Amblypygids, or whip spiders, are arachnids that often have highly elongated spined pedipalps. These limbs are used to strike at, and secure, prey before processing by the chelicerae. Amblypygi pedipalps are multifunctional, however, being used in courtship and contest, and vary greatly in form between species.
The Sensory and Behavioural Biology of Whip Spiders (Arachnida, Amblypygi)
2011年1月1日 · Whip spiders (Arachnida, Amblypygi) comprise a small and little-studied arachnid order. They have elongated antenniform forelegs which function in a sensory capacity and are not used for locomotion. These antenniform legs are covered in large numbers of chemo- and mechanosensory sensilla, and others of unknown function.
Assessing the patterns and drivers of shape complexity in the ...
2021年7月14日 · Amblypygi is an arachnid order possessing a unique pair of spined pedipalps: appendages that perform in prey capture, courtship, and contest. Pedipalp length, hypothesized to be under sexual selection, varies markedly across amblypygid species, and pedipalp spination, thought to reflect selection for function in prey capture, also differs ...
Eight New Species of Charinus Simon, 1892 (Arachnida: Amblypygi …
2016年2月17日 · Amblypygi is a small arachnid order with a worldwide distribution and the largest number of described species in the Neotropics [1, 2]. Currently, circa of 170 species are known and several new ones have been described in the last few years from all over the world [3 – 16].
Genomic resources and toolkits for developmental study of whip …
2020年8月28日 · Using embryonic transcriptomes from three species of Amblypygi, we show that the ancestral whip spider exhibited duplications of all ten Hox genes. We deploy these resources to show that paralogs of the leg gap genes dachshund and homothorax retain arachnopulmonate-specific expression patterns in P. marginemaculatus .

2020年8月28日 · The phylogenetic position of Amblypygi in Arachnopulmonata posits them as an interesting group to test the incidence of the proposed genome duplication in the common ancestor of Arachnopulmonata, as well as the degree of retention of duplicates over 450 Myr.
