Geophilidae
The Geophilidae are a polyphyletic, cosmopolitan family of soil centipedes in the superfamily Geophiloidea containing the mostly defunct clades Aphilodontidae, Dignathodontidae, Linotaeniidae, Chilenophilinae, and Macronicophilidae. Species in this family are characterized by mandibles with a single pectinate lamella, slender antennae, sternal pores with variable arrangement, a generally slightly or moderately elongate head, frequently undivided coxosternite with two paramedian sclerotized lines, claws without rows of filament, and female gonopods usually being an undivided lamina. Compared to most other families in the suborder Adesmata, this family features a modest number of leg-bearing segments (no more than 125) and limited variation in this number within each species. Two species in this family include centipedes with only 29 pairs of legs: ''Geophilus persephones'' (29 pairs in the only specimen, a male), and '' G. richardi'' (29 or 31 pairs in the males and 33 pairs in ...

Geophilus Flavus
''Geophilus flavus'' is a terrestrial, soil-dwelling, species of centipede in the Geophilidae family. ''G. flavus'' occurs in a range of habitats across central Europe, North America, Australia and other tropical regions. Geophilomorph centipedes, like centipedes generally, are primary predators, hunting predominantly in underground soil burrows or above ground leaf litter. Their consumption behaviours are influenced by environment and seasonal factors. Given their lack of economic value and marginal medical significance, ''G.flavus'' remains largely understudied in mainstream research. Some recent studies have detailed the evolutionary development of ''G.flavus'' and Geophilidae generally, illustrating developed predatory features like forcipule venom glands. Description These centipedes are yellow and may grow up to in length. They are sightless, and rely on specialised sensory organs to sense movement, humidity and light. Like other myriapods, they have an exoskeleton an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geophilus Persephones
''Geophilus persephones'' is a species of soil centipede in the family Geophilidae discovered in 1999. This species is named after Persephone, the queen of the underworld in Greek mythology, and found in caves in the Gouffre de la Pierre Saint-Martin. It has elongated antennae and legs as well as abundant sensory setae, and like other geophilomorhps it lacks sight, has a flattened trunk, and is well adapted to underground life. This species was the first troglomorphic geophilomorph ever discovered and one of the only two in existence along with ''Geophilus hadesi''. Known from a single male specimen, this species has only 29 pairs of legs, one of only two species in the Geophilidae family to have so few leg pairs.

Acanthogeophilus
''Acanthogeophilus'' is a genus of soil centipedes in the family Geophilidae, found in the centro-west part of the Mediterranean region. The species in this genus are slender, 2-3 centimeters long, with between 67-71 pairs of stout legs, peculiar spine-like processes on the ultimate legs, a claw-like pretarsus, complete coxo-pleural sutures, incomplete chitin-lines, absence of a carpophagous pit, possession of only basal denticles, and a transverse band porefield with scattered, anterior pores on the coxopleuron. The genus contains the following species: *''Acanthogeophilus dentifer'' Minelli, 1982 *''Acanthogeophilus spiniger ''Acanthogeophilus spiniger'' is a species of soil centipede in the family Geophilidae found in Northwest Africa.

Geophilus Richardi
''Geophilus richardi'' is a species of soil centipede in the family Geophilidae The Geophilidae are a polyphyletic, cosmopolitan family of soil centipedes in the superfamily Geophiloidea containing the mostly defunct clades Aphilodontidae, Dignathodontidae, Linotaeniidae, Chilenophilinae, and Macronicophilidae. Species in ... found in France, Italy, and the Ionian Islands. Females of this species have 33 pairs of legs; males have 29 or 31. This species is one of only two in the family Geophilidae to include centipedes with as few as 29 leg pairs. This species grows up to 10 millimeters long, has no carpophagus pit or pore-fields, and has a gradually tapering, curved pretarsus of the second maxillae. ''G. richardi'' lacks typical ventral pores between 2–4mm. The sternites instead bear a small number of pores between 0.5–1mm that differ from micropores, which are unbounded by a cuticular ring. These are possibly the remnants of typical ventral pores, their smaller size ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geophilomorpha
The centipedes or Chilopoda are divided into the following orders. Scutigeromorpha The Scutigeromorpha are anamorphic, reaching 15 leg-bearing segments in length. Also known as house centipedes, they are very fast creatures, and able to withstand falling at great speed: they reach up to 15 body lengths per second when dropped, surviving the fall. They are the only centipede group to retain their original compound eyes, within which a crystalline layer analogous to that seen in chelicerates and insects can be observed. They also bear long and multi-segmented antennae. Adaptation to a burrowing lifestyle has led to the degeneration of compound eyes in other orders; this feature is of great use in phylogenetic analysis. The group is the sole extant representative of the Notostigmophora, defined by having a single spiracle opening at the posterior of each dorsal plate. The more derived groups bear a plurality of spiracular openings on their sides, and are termed the Pleurostigmopho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Centipede
Centipedes (from New Latin , "hundred", and Latin , " foot") are predatory arthropods belonging to the class Chilopoda (Ancient Greek , ''kheilos'', lip, and New Latin suffix , "foot", describing the forcipules) of the subphylum Myriapoda, an arthropod group which includes millipedes and other multi-legged animals. Centipedes are elongated segmented (metameric) creatures with one pair of legs per body segment. All centipedes are venomous and can inflict painful bites, injecting their venom through pincer-like appendages known as forcipules. Despite the name, centipedes can have a varying number of legs, ranging from 30 to 382. Centipedes always have an odd number of pairs of legs; no centipede has exactly 100. Like spiders and scorpions, centipedes are predominantly carnivorous. Their size ranges from a few millimetres in the smaller lithobiomorphs and geophilomorphs to about in the largest scolopendromorphs. Centipedes can be found in a wide variety of environments.

Linotaeniidae
Linotaeniidae are a monophyletic clade of soil centipedes in the family Geophilidae found mostly in the temperate regions of the Holarctic as well as the south Andes. Species in the clade Linotaeniidae are characterized by a body that usually tapers toward the anterior tip; mandibles with a single pectinate lamella; second maxillae with coxo-sternite usually undivided and claws without projections; forcipular segment short, with tergite remarkably wide, forcipules evidently tapering; coxal organs opening through distinct pores on the ventral surface of the coxo- pleura.
