Gonibregmatidae
Gonibregmatidae is a family of soil centipedes belonging to the superfamily Geophiloidea. In 2014, a phylogenetic analysis based on morphological and molecular data found this family to be paraphyletic with respect to the families Neogeophilidae and Eriphantidae, which authorities now deem to be junior synonyms for Gonibregmatidae. This family now includes more than 20 species in at least 10 genera. Description Centipedes in this family feature a short head and mandibles with a single row of short teeth. The number of leg-bearing segments in this family varies within as well as among species and ranges from 57 to 191. These centipedes are very elongated with a high mean number of trunk segments (often greater than 100) and great variability in this number within species. The minimum number of legs recorded in this family (57 pairs) appears in the species ''Himantosoma porosum''. This family includes the species '' Gonibregmatus plurimipes'', which can have as many as 191 l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geophiloidea
Geophiloidea is a superfamily in the order Geophilomorpha and suborder Adesmata containing the families Zelanophilidae, Gonibregmatidae Gonibregmatidae is a family of soil centipedes belonging to the superfamily Geophiloidea. In 2014, a phylogenetic analysis based on morphological and molecular data found this family to be paraphyletic with respect to the families Neogeophil ... (including Eriphantidae and Neogeophilidae), and Geophilidae (including Aphilodontidae, Dignathodontidae, Linotaeniidae, Chilenophilinae, and Macronicophilidae). This superfamily is characterized by features of the chamber leading to the mouth opening: The border between the proximal ( clypeal) part and the distal ( labral) part of the roof of this chamber (epipharynx) is divided into two lobes. Furthermore, the spines on the bottom of this chamber (hypopharynx) extend to most frontal and ventral parts of this floor. Another diagnostic trait of this superfamily are the mandibles, which each ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gonibregmatus Plurimipes
''Gonibregmatus plurimipes'' is a species of soil centipede in the Gonibregmatidae family. This centipede is found in Fiji. This species is notable for featuring 191 pairs of legs, which is the maximum number found in any centipede. Discovery This species was described in 1920 by American myriapodologist Ralph Vary Chamberlin. Chamberlain based the original description of this species on a single specimen. This holotype is deposited in the Museum of Comparative Zoology at Harvard University. This specimen was found in Lomati, on Kaduvu island in Fiji, and remains the only specimen recorded. Description This species is reddish-yellow, and the only specimen described has 191 pairs of legs. The antennae are broad and flattened at the base, gradually narrowing to the middle, then almost uniform and cylindrical beyond that point. The head lacks a distinct transverse suture, and the middle part of the labrum has a convex margin. The short sclerite in front of the forcipular t ...

Gonibregmatus
''Gonibregmatus'' is a genus of soil centipedes in the family Gonibregmatidae. This genus was described by British entomologist George Newport in 1843. These centipedes are found from the Philippines and the Malay archipelago to Fiji. Description Centipedes in this genus feature a convex labral margin fringed by bristles, uniarticulate telepodites on the first maxillae, claws on the second maxillae without filaments, additional sclerites flanking the trunk tergites, and sternal pores in two transverse bands. These centipedes range in length from about 10 cm to 15 cm and have 99 to 191 pairs of legs. The small species '' Gonibregmatus olivaceus'' (with males 97 mm long and females 110 mm long) can have as few as 99 leg pairs (males with 99 to 103 pairs, females with 113 pairs), the minimum number in this genus. The smallest species, '' G. insularis'', reaches only 97 mm in length, whereas the largest species, '' G. fijianus'', can reach 150 mm in l ...

Eucratonyx
''Eucratonyx'' is a genus of centipedes in the family Gonibregmatidae. This genus was described in 1898 by British zoologist Reginald Innes Pocock. Centipedes in this genus are found from the Andaman Islands to New Britain. Description Centipedes in this genus feature a concave labral margin fringed by denticles, sternal pores in two anterior paired groups and a posterior band, enlarged claws on some anterior legs with a very elongate basal branch, and coalescent female gonopod Gonopods are specialized appendages of various arthropods used in reproduction or egg-laying. In males, they facilitate the transfer of sperm from male to female during mating, and thus are a type of intromittent organ. In crustaceans and millipe ...s. These centipedes range from about 8 cm to 13 cm in length and have 103 to 129 pairs of legs. The smallest species in this genus, '' Eucratonyx hamatus'', can reach 85 mm in length and range from 103 pairs of legs (in males) to 125 pairs (in ...

Geophilomorpha
Geophilomorpha is an order of centipedes commonly known as soil centipedes. The name "Geophilomorpha" is from Ancient Greek roots meaning "formed to love the earth." This group is the most diverse centipede order, with 230 genera. These centipedes are found nearly worldwide but are absent in Antarctica and most Arctic regions. Description Centipedes in this order are epimorphic, hatching with a full complement of segments. These centipedes each have an odd number of leg-bearing segments ranging from 27 (in the genus '' Schendylops'') to 191 (in the species '' Gonibregmatus plurimipes''). They are eyeless and blind, with long and narrow bodies, ranging from yellow to brown in color and from about 1 cm to 22 cm in length. They bear spiracles on all leg-bearing segments except the first and the last. The antennae have 14 segments and are usually slightly attenuated. Suborders and families This order is a monophyletic group including two suborders: the monophyletic Placodesmata, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five Borders of the oceans, oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .
