Macrothele Undata

	Macrothele Undata ''Macrothele'' is a genus of Mygalomorphae, mygalomorph spiders in the family Macrothelidae, and was first described by Anton Ausserer, A. Ausserer in 1871. Most of the species in the genus occur in Asia, from India to Japan, and Java, with five found in Africa, and two in Europe. The name is derived from Ancient Greek wikt:μακρός#Ancient Greek, μακρός ("makro-"), meaning "big", and wikt:θηλή#Ancient Greek, θηλή ("thele"), referring to the spinneret (spider), spinnerets. Description Spiders of this genus are fairly large, with females of some Chinese species ranging from in body length. Males are smaller, sometimes only half that length.

	Dipluridae The family Dipluridae, known as curtain-web spiders (or confusingly as funnel-web tarantulas, a name shared with other distantly related families) are a group of spiders in the infraorder Mygalomorphae, that have two pairs of booklungs, and chelicerae (fangs) that move up and down in a stabbing motion. A number of genera, including that of the Sydney funnel-web spider (''Atrax''), used to be classified in this family but have now been moved to Atracidae. Description Dipluridae lack rastella (stout conical spines on their chelicerae). Their carapace is characterized by the head region not being higher than the thoracic region. Their posterior median spinnerets (silk-extruding organs) are much shorter than their posterior lateral spinnerets, which have three segments, and are elongated (almost as long as their opisthosoma). Most of the species are medium to small-sized spiders; some may measure about 15 mm.Murphy & Murphy 2000 The cave species '' Masteria caeca'' is eyele ...

	Macrothele Bannaensis ''Macrothele'' is a genus of mygalomorph spiders in the family Macrothelidae, and was first described by A. Ausserer in 1871. Most of the species in the genus occur in Asia, from India to Japan, and Java, with five found in Africa, and two in Europe. The name is derived from Ancient Greek μακρός ("makro-"), meaning "big", and θηλή ("thele"), referring to the spinnerets. Description Spiders of this genus are fairly large, with females of some Chinese species ranging from in body length. Males are smaller, sometimes only half that length. Macrothelids can be distinguished from other mygalomorph spiders by their larger posterior sigillae on the sternum, and the arrangement of the rows of teeth on the margin of the chelicerae: larger front-facing margin and smaller rear-facing. These spiders build tube-webs or funnel-webs under rocks or logs, or in crevices in the ground. Taxonomy The genus ''Macrothele'' was erected by Anton Ausserer in 1871, with the type species ...

	Actinopodidae Actinopodidae is a family of mygalomorph spiders found in mainland Australia and South America usually in open forest. Species are most common in Queensland, Australia. It includes mouse spiders ('' Missulena'' species), whose bites, though rare, are considered medically significant and potentially dangerous. Description Actinopodidae has wider vision then most other Australian mygalomorphs and have a wide front to their carapace. Members of the family are stout black with species size varying from 10 mm-35 mm in length. Species have distinctively bulbous heads and jaw regions. They are oftentimes confused with funnel-web spiders. Depending on the species, the abdomen is black or dark blue with a light grey to white patch top. Legs are dark and may appear thin and the head is shiny black. Female of the family are stockier and larger. Burrow They live in soil covered burrows with a hinged top. Burrows can extent to a depth of 30 cm (12 inches). The purpose o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Porrhothelidae ''Porrhothele'' is a genus of mygalomorph spiders endemic to New Zealand. They are the only members of the family Porrhothelidae. They were first described by Eugène Louis Simon in 1892. Originally placed with the curtain web spiders, it was moved to the Hexathelidae in 1980, they were placed in their own family in 2018. Members of Porrhothelidae are distinguished from other mygalomorph spiders by the small posterior sigillae and a single row of teeth on the forward-facing margin of the chelicerae. Males have many strong spines on the forward-facing margin of their tibiae. Taxonomy The genus ''Porrhothele'' was erected by Eugène Simon in 1892 for the species '' Porrhothele antipodiana''. Simon transferred these from ''Mygale'', a genus previously used for many mygalomorph spiders, but is no longer in use. He placed this genus in the subfamily Diplurinae, which later became the family Dipluridae. Raven transferred the genus to Hexathelidae, where it remained until the re ...
