Grassatores
The Grassatores are the most diverse infraorder of the Laniatores. It includes over 3,500 species distributed mainly in the tropicsKury, A.B.(2003). Annotated catalogue of the Laniatores of the New World (Arachnida, Opiliones). '' Revista Ibérica de Aracnología'', vol. especial monográfico 1: 1-337. They are characterized by the male genitalia without musculature, operated by hydraulic pressure and by the double tarsal claws of posterior legs. Superfamilies * Assamioidea Sørensen, 1886 * Phalangodoidea Simon, 1879 * Samooidea Samooidea is a large superfamily in the Grassatores group of harvestmen. It includes around 380 species distributed throughout the tropics. They are characterized by the complex male genitalia, with eversible complementary sclerites. The Samooid ...

Podoctidae
Podoctidae is a family of the harvestman infraorder Grassatores with about 130 described species. (2007): Podoctidae Roewer, 1912. In: Pinto-da-Rocha ''et al.'' 2007: 221ff Description Body length ranges from 2.5 to 5 millimeters, with leg length ranging from three to almost thirty mm. While most species are brown to yellow, some are deep green. The legs may be ringed in black and yellow. The penis is uniquely built. Distribution Most species occur in Southeast Asia, especially in New Guinea. Others are found in Melanesia, Micronesia, Japan, India and Sri Lanka, Madagascar, the Seychelles and Mauritius, and central Africa. ''Ibantila cubana'' was introduced in a botanical garden in Cuba. Although one Podoctidae was described from Brazil in 1938, it was later transferred to Triaenonychidae. The oldest known member of the family is '' Burmalomanius'' from the mid-Cretaceous Burmese amber of Myanmar. Relationships Although Podoctidae are currently included in Samooidea, and are su ...

Phalangodoidea
The Phalangodoidea are a superfamily of the harvestman infraorder Grassatores with three recognized families and 220 species. It is not to be confused with the similarly spelled subfamily Phalangioidea, which is also a harvestman superfamily, but within the suborder Eupnoi. Families * Oncopodidae Thorell, 1876 (about 70 species) * Phalangodidae The Phalangodidae are a family of harvestmen with about 30 genera and more than 100 described species, distributed in the Holarctic region. It is not to be confused with the harvestman family Phalangiidae, which is in the suborder Eupnoi. ...

Laniatores
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. Laniatores are typically (relatively) short-legged, hard-plated, spiny Opiliones, common under logs and stones, in leaf litter and in caves. They often have spiny pedipalps and paired or branched claws on the third and fourth pairs of legs.Pinto-da-Rocha ''et al.'' 2007: 17 The largest family is Gonyleptidae Sundevall, 1833, endemic of the Neotropics, with over 800 valid species and showing many cases of maternal and paternal care. Identification The dorsal scutum consists of a single piece, with the carapace or peltidium entirely fused with abdominal scutum. The pedipalpus is usually robust and armed with strong spines. The ovipositor is short and unsegmented (derived character state shared with the Dyspnoi). The penis is complex, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samooidea
Samooidea is a large superfamily in the Grassatores group of harvestmen. It includes around 380 species distributed throughout the tropics. They are characterized by the complex male genitalia, with eversible complementary sclerites. The Samooidea are closely related to Zalmoxoidea, although the exact relationships are not yet understood. Families included * Biantidae Thorell, 1889 * Escadabiidae Kury & Pérez, 2003 * Kimulidae Pérez, Kury & Alonso-Zarazaga, 2007 * Podoctidae Roewer, 1912 * Samoidae Samoidae is a family of the harvestman infraorder Grassatores with about fifty described species. (2007): Samoidae. Sørensen, 1886. In: Pinto-da-Rocha ''et al.'' 2007: 224ff Description The body length of members of this family ranges from ab ...

Gonyleptoidea
Gonyleptoidea is the most diverse superfamily of the Grassatores. It includes around 2,500 species distributed in the tropics. They are characterized by the simplified male genitalia, with the glans free subapical in the truncus. Gonyleptoidea is the only group of harvestmen to show maternal care of offspring. Families * Agoristenidae Šilhavý, 1973 * Cosmetidae Koch, 1839 * Cranaidae Roewer, 1913 * Cryptogeobiiidae Kury, 2014 * Gerdesiidae Bragagnolo, Hara & Pinto-da-Rocha, 2015 *Gonyleptidae Sundevall, 1833 * Manaosbiidae Roewer, 1943 * Metasarcidae Kury, 1994 * Otilioleptidae Acosta, 2019 *Stygnidae The Stygnidae are a family of neotropical harvestmen within the suborder Laniatores. Name The name of the type genus is derived from Ancient Greek ''stygnos'' "diabolic being". (2007): Stygnidae Simon, 1879. In: Pinto-da-Rocha ''et al.'' 2007: 2 ...

Tropics
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. , the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
