Scorpions represent an iconic lineage of arthropods, historically renowned for their unique bauplan, ancient fossil record and venom potency. Yet, higher level relationships scorpions, based exclusively on morphology, remain virtually untested, no multilocus molecular phylogeny has been deployed heretofore towards assessing the basal tree topology. We applied a phylogenomic assessment to resolve scorpion phylogeny, first time, our knowledge, sampling extensive sequence data from all...
Scorpions constitute a charismatic lineage of arthropods and comprise more than 2500 described species. Found throughout various tropical temperate habitats, these predatory arachnids have long evolutionary history, with fossil record that began in the Silurian. While all scorpions are venomous, asymmetrically diverse family Buthidae harbors nearly half diversity extant scorpions, but one 58 species medically significant to humans. However, lack densely sampled scorpion phylogeny has...
Scorpions previously assigned to the genus Liocheles Sundevall, 1883, of family Hormuridae Laurie, 1896, are widely distributed in tropical forests Indo-Pacific region. Revisionary systematics these poorly known scorpions has revealed a tremendous diversity species. As part an ongoing investigation, first analysis hormurid scorpion phylogeny based on morphological data scored for all currently recognized species Hormiops Fage, , Hormurus Thorell, 1876, and Liocheles, is presented. The...
The family Hemiscorpiidae is closely related to the Liochelidae. Within Hemiscorpiidae, Oriental species are particularly interesting. Most of them exhibit highly derived characters in comparison their African relatives. Males possess a strongly elongated metasoma and similarly telson bearing pair tuberculiform processes at base aculeus. Furthermore, Hemiscorpius lepturus Peters, 1861, which occurs Iraq Iran, known have an extremely virulent venom with cytotoxic haemolytic components. It...
Insemination in scorpions is carried out by means of a partly sclerotized structure, the spermatophore, which composed two separate halves, hemispermatophores. In most genera these reproductive structures can be used to differentiate species. However, many taxa such as genus Euscorpius and family Diplocentridae lack morphological diversity observed copulatory organs other arthropods, rendering them useless for species level taxonomy. Such structural stasis, however, suggests that...
SUMMARY Scorpions (order Scorpiones) are unusual among arthropods, both for the extreme heteronomy of their bauplan and high gene family turnover exhibited in genomes. These phenomena appear to be correlated, as two scorpion species have been shown possess nearly twice number Hox genes present most arthropods. Segmentally offset anterior expression boundaries a subset paralogs correspond transitions segmental identities posterior tagmata, suggesting that scorpions may achieved by...
Although being one of the most well-known animal groups, functional and constructional aspects scorpions especially their tail (metasoma) have so far been overlooked. This represents a special construction, as it consists five tube-shaped segments made up strong cuticle, which are movable against each other thus manoeuvre notorious stinger both quickly very precisely in space. high mobility an exoskeletal structure can be attributed to connection between described here for first time. joint...
New Guinea is the largest Pacific island, and world's second largest, with a land area of about 785,000 km2. Located north Australia, island was gradually shaped since Eocene by geologically recent sequential accretion several arc systems onto northern part Australian Craton. This complex geological history has resulted in tremendous biological diversity high rates endemism. On other hand, rugged mountainous landscape lack infrastructure hampered scientific research country for most Papuan...
Abstract Phocyx gen. nov. and australis sp. have been newly described from New South Wales, Australia. This represents the first record of family Buemarinoidae in Australia, thereby remarkably extending known distribution this ancient relictual group Opiliones. Our descriptions include images genital morphology, a critical element diagnosis. Additionally, we present discourse on conserved external morphology within Triaenonychoidea underscore significance taxonomy superfamily. Very low...

Based on a recently published phylogeny of Australasian hormurid scorpions, HormiopsFage, 1933, previously considered doubtful taxon by some authors, is now reinstated as valid genus. These lithophilous scorpions are currently only recorded from two groups granitic islands in the South China Sea, Con Đo Archipelago near southern tip Vietnam and Seribuat off south-east coast Peninsular Malaysia. Each these archipelagos harbouring distinct species. Newly collected specimens enable examination...
Scorpions have always inspired fear and fascination because of the potency their venoms. Although this ancient arachnid group is relatively small (ca. 2400 species) has been continuously studied for past century, taxonomy still in a state flux correct identification species often remains difficult. With more than 725 9000 specimens, Zoological Museum Hamburg (ZMH) holds one largest most significant scorpion collections world. This collection also contains many historical types described by...
A new species of Ananteris Thorell from French Guyana (Scorpiones, Buthidae).-A Buthidae) is described rain forest in the region Saint Eugène, Guyana.This third known that country.The total number genus now raised to 22.
