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]
Arachnida is a class of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. Arachnida includes orders containing spiders, scorpions, ticks, mites, harvestmen, and solifuges. In 2019, a molecular phylogenetic study also placed horseshoe crabs in Arachnida.
The Opiliones are an order of arachnids colloquially known as harvestmen, harvesters, or daddy longlegs. As of April 2017, 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.
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.
Laniatores is the largest suborder of the arachnid order Opiliones with over 4,000 described species worldwide. The majority of the species are highly dependent on humid environments and usually correlated with tropical and temperate forest habitats.
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".
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.
Niphargus hadzii is a species of crustacean in family Niphargidae. It is endemic to Slovenia, and is named after Slovene zoologist Jovan Hadži.
Mitopus morio 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 with 5 genera and 57 extant species and one fossil species.
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 31 described species in 3 genera, found in Europe and North America.
Daddy longlegs or daddy long legs may refer to:
Jovan Hadži was a Slovenian zoologist of Serbian origin.
Trogulus tricarinatus is a species of harvestman. It is found in Europe and North America.
Taracidae is a family of harvestmen in the order Opiliones. There are 4 genera and 23 described species in Taracidae.
Travunioidea is a superfamily of armoured harvestmen in the order Opiliones. There are 4 families and more than 70 described species in Travunioidea.
Ischyropsalis is a genus of harvestmen in the family Ischyropsalididae, found in Europe. There are more than 20 described species in Ischyropsalis.
