Titanoecidae
Titanoecidae is a family of araneomorph spiders first described by Pekka T. Lehtinen in 1967. It is fairly widespread in the New World and Eurasia with five genera and more than 50 species worldwide. These are mostly dark-colored builders of "woolly" (cribellate) silk webs. Several species are found at relatively high altitudes in mountain ranges and may be very common in such habitats. Genera , the World Spider Catalog accepts the following genera: *''Anuvinda'' Lehtinen, 1967 – Asia *''Goeldia'' Keyserling, 1891 – South America, Mexico *''Nurscia'' Simon, 1874 – Asia, Europe *''Pandava'' Lehtinen, 1967 – Asia, Africa, Papua New Guinea *''Titanoeca'' Thorell, 1870 – Asia, North America, Europe, Ecuador, Algeria See also * List of Titanoecidae species * Titanoecoidea The Titanoecoidea or titanoecoids are a proposed taxon of araneomorph spiders at the superfamily rank.

Pandava (spider)
''Pandava'' is a genus of araneomorph spiders in the family Titanoecidae. Taxonomy In 1967, Pekka T. Lehtinen transferred the species ''Amaurobius laminatus'', first described by Tamerlan Thorell in 1878, into his newly created genus ''Pandava'' as ''P. laminata'', placing it in the family Titanoecidae. Over 30 years later, in 2001, a further species, ''Pandava hunanensis'', was added to the genus. A major revision of ''Pandava'' in 2010 saw five new species being added. Diagnosis Male spiders placed in the genus ''Pandava'' differ from other species of Titanoecidae in features of the palpal bulb: the tegular process (a projection from the tegulum) is smaller; the median apophysis (one of the hardened plates making up the palpal bulb) is thumb-shaped. Females differ in features of the epigynum: the copulatory openings are more anterior. Species , the World Spider Catalog accepted eleven species: *'' Pandava andhraca'' (Patel & Reddy, 1990) – India *'' Pandava aruni'' Bo ...

Pandava Laminata
''Padava laminata'' is a species of araneomorph spider in the family Titanoecidae. It is widely distributed from East Africa through China to New Guinea and the Marquesas Islands. Description ''Pandava laminata'' has a brownish body and legs with a much paler abdomen and darker brown chelicerae (fangs). Males have more varied colouring than females, with darker brown around the head area and yellowish brown on the sternum as well as on the second to fourth pairs of legs. Females range from about 6–8 mm in total body length, males being slightly smaller at about 5.5–6 mm. Like all titanoecids, males have a complex projection (apophysis) on the tibia of their palps, with three main parts (lobes). In ''Pandava laminata'' males the lobe closest to the spider's mouth (the prolateral lobe) is undivided and short. The female epigyne is semi-circular; the anterior rims are longer than their distance apart. Distribution ''Padava laminata'' is native to Tanzania, Kenya, Mada ...

Titanoecoidea
The Titanoecoidea or titanoecoids are a proposed taxon of araneomorph spiders at the superfamily rank. The taxon contains two families of spiders, Phyxelididae and Titanoecidae. Although some phylogenetic studies have shown these two families to form a clade, other studies have not, placing Titanoecidae outside the RTA clade while Phyxelididae is placed inside it. A 2011 classification of spider families leaves both Phyxelididae and Titanoecidae outside the RTA clade as "unplaced non-Orbiculariae Orbiculariae is a potential clade of araneomorph spiders, uniting two groups that make orb webs. Phylogenetic analyses based on morphological characters have generally recovered this clade; analyses based on DNA have regularly concluded that the ... families".

Cribellate
Cribellum literally means "little sieve", and in biology the term generally applies to anatomical structures in the form of tiny perforated plates. In certain groups of diatoms it refers to microscopically punctured regions of the frustule, or outer layer. In certain groups of spider species, so-called cribellate spiders, the cribellum is a silk spinning organ. Unlike the usual spinnerets of spiders, the cribellum consists of one or more plates covered in thousands of tiny spigots, tiny holes that hardly project from the surface, in contrast to the elongated spigots that project from spinnerets. These minute spigots produce extremely fine fibers, merely tens of nanometres thick, which are combed out by the spider's calamistrum, producing silk with a woolly texture. The fibers are so small in diameter that they are strongly subject to Van der Waals forces. In addition, the fibres have a surface that absorbs waxes from the epicuticle of insect prey on contact. This creates a pow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araneomorphae Families
The Araneomorphae (also called the Labidognatha) are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae (tarantulas and their close kin), where they point straight down. Araneomorphs comprise the vast majority of living spiders. Distinguishing characteristics Most spider species are Araneomorphae, which have fangs that face towards each other, increasing the orientations they can employ during prey capture. They have fewer book lungs (when present), and the females typically live one year. The Mygalomorphae have fangs that face towards the ground, and which are parallel to the long axis of the spider's body, thus they have only one orientation they can employ during prey capture. They have four pairs of book lungs, and the females often live many years. Image:Atrax robustus.jpg, This ''Atrax robustus'' shows the orientation of Myglamorphae fangs. Image:Che ...
