Anelasmocephalus hadzii is a species of trogulid, a group of opiliones, native to Europe. [1]
A. hadzii has all legs except for the calcaneus are very hairy and warty. Soil particles, as with most trogulidae, are tightly glued to these warts. The glans of the penis is long and has a hook at the end. The distal end of this is long and thin. [2]
Arachnids are arthropods in the class Arachnida of the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons.
The Opiliones are an order of arachnids, colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. As of July 2024, over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014.
The Pholcidae are a family of araneomorph spiders. The family contains more than 1,800 individual species of pholcids, including those commonly known as cellar spider, daddy long-legs spider, carpenter spider, daddy long-legger, vibrating spider, gyrating spider, long daddy, skull spider, and angel spider. The family, first described by Carl Ludwig Koch in 1850, is divided into 94 genera.
A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron.
Gonyleptidae is a neotropical family of harvestmen with more than 800 species, the largest in the suborder Laniatores and the second largest of the Opiliones as a whole. The largest known harvestmen are gonyleptids.
The penis of the Opiliones (harvestmen) is an intromittent organ that is not present in other arachnids. It consists of a long shaft and a terminal capsule called a glans, containing a stylus and ejaculatory duct. It may have from one to three muscles, or none as in the specialized lineage Grassatores, where the penis is operated by haemolymph pressure. In some members of the Cyphophthalmi, the structure has been termed a "spermatopositor".
The Grassatores Kury, 2002 are the most diverse infraorder of the Laniatores. It includes over 3,700 species distributed mainly in the tropics They are characterized by the male genitalia without musculature, operated by hydraulic pressure and by the double tarsal claws of posterior legs.
Dicranopalpus ramosus is a species of harvestman. Males are up to 4 mm long, females can reach up to 6 mm. Both sexes have very long legs, with a distinct elongated apophysis that reaches almost to the end of the tibia. This makes their pedipalps look forked. Their body is brownish with dark markings, the females being lighter colored.
Dyspnoi is a suborder of harvestmen, currently comprising 43 extant genera and 356 extant species, although more species are expected to be described in the future. The eight families are currently grouped into three superfamilies: the Acropsopilionoidea, Ischyropsalidioidea, and Troguloidea.
Mitopus morio is a species of harvestman arachnid belonging to the family Phalangiidae.
Phalangium opilio is a species of harvestman belonging to the family Phalangiidae.
The Neogoveidae are a family of harvestmen with 27 described species in eight genera. However, eight species of Huitaca, 17 species of Metagovea and 12 species of Neogovea are currently awaiting description.
Trogulidae is a family of harvestmen comprising 65 extant species in five genera.
Nipponopsalididae is a family of harvestmen with three described species in one genus, Nipponopsalis, which is found in East Asia.
Ischyropsalididae is a family of harvestmen with 35 described species in 3 genera, found in Europe and North America.
Jovan Hadži was a Slovenian zoologist of Serbian origin.
Taracidae is a family of harvestmen in the order Opiliones. There are 4 genera and 23 described species in Taracidae.
Ischyropsalis is a genus of harvestmen in the monotypic family Ischyropsalididae, with 24 described species. They are found in Europe.
