Tuoba pallida is a species of soil centipede in the Geophilidae family. [2] This centipede is a littoral species endemic to Australia. [3]
This species was first described in 1998 by R.E. Jones. The original description is based on a female holotype and six paratypes (two males and four females) found in 1980. The holotype and four of the paratypes were found in silver gull nest litter in Rockingham, on Penguin Island, near Perth, in Western Australia. The other two paratypes were found in coast shrub litter in Windy Harbour, south of Northcliffe, in Western Australia. All type specimens are deposited in the Western Australian Museum in Perth. [1]
This species is white throughout and can reach up to 25 mm in length. Males of this species have 55 pairs of legs; females have 57 or 59 leg pairs. The body is sparsely covered with setae. The labrum has three pieces, with at least four teeth on the middle piece. The second maxillae feature claws that seem to end in a bristle and are surrounded by four or five setae. Pores appear in a circular group on the first segment but form a posterior band on all other segments. The ultimate legs are long and thin, about as long as the other legs, slightly swollen in the male, but less swollen in the female. Each of the ultimate legs has a claw at the distal end. This centipede can be readily identified based on its very pale pigmentation and long thin ultimate legs. [1]
This species occurs in coastal south-west Western Australia. [4] [5]
These centipedes are solitary terrestrial predators that inhabit plant litter and soil. [5]
Centipedes are predatory arthropods belonging to the class Chilopoda 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 stings, injecting their venom through pincer-like appendages known as forcipules or toxicognaths, which are actually modified legs instead of fangs. Despite the name, no centipede has exactly 100 legs; the number of pairs of legs is an odd number that ranges from 15 pairs to 191 pairs.
Nannarrup is a genus of soil centipedes in the family Mecistocephalidae; this genus includes a single species, Nannarrup hoffmani, also known as Hoffman's dwarf centipede. This centipede was discovered in Central Park in New York City and was the first new species to be discovered in that park in more than a century. This species is the smallest species in the family Mecistocephalidae, reaching only 10.3 mm in length, and has only 41 pairs of legs, the minimum number recorded in this family.
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.
Geophilus hadesi is a species of soil centipede in the family Geophilidae. This centipede is a troglobite, spending its entire life cycle in a cave environment. This species and Geophilus persephones are the only two troglobites known in the order Geophilomorpha. The species G. hadesi is named after Hades, god of the underworld in Greek mythology and the husband of Persephone, the namesake of the first troglobite discovered among the soil centipedes. The species G. hadesi has been observed in a cave as far as 1,100 meters below the surface, the deepest underground that any centipede has ever been recorded.
Plutonium zwierleini, in the monotypic genus Plutonium, is one of the largest scolopendromorph centipedes in Europe, and one of the few potentially harmful to humans. Nevertheless, it has been rarely reported, only from the southern part of the Iberian and Italian peninsulas, Sardinia and Sicily.
Geophilus truncorum is a species of soil centipede in the family Geophilidae found across Western Europe, though it reaches as far as Poland, Italy, and Morocco. This centipede is relatively small, growing up to 20mm in length, with a yellow or orangeish brown body and dark yellow or brown head, denser and shorter hair than most Geophilus species, a main plate almost as elongated as in G. flavus (115:100), and distinct carpophagus fossae on the anterior sternites. Males of this species have 35 to 41 pairs of legs; females have 37 to 41.
Geophilus pusillifrater is a species of soil centipede in the family Geophilidae found in Bosnia-Herzegovina and Britain. It's a relatively small, pale species, prehensorial claws with pointed teeth at the base, distinct chitin lines, and a very broad ventral plate of the pregenital segment. It's at least partially a littoral creature. Males of this species have 39 or 41 pairs of legs; females have 43 leg pairs.
Arthrorhabdus paucispinus is a species of centipede in the family Scolopendridae. Endemic to Australia, it was first described in 1984 by Australian myriapodologist L. E. Koch. It is a medium-sized species, up to 64 millimetres long, with a reddish-brown head and pale brown body segments. It has 14 to 18 segments on its antennae, large teeth on the feeding mouthparts, and its last pair of legs feature short bristles and a small projection.
Arthrorhabdus mjobergi is a species of centipede in the Scolopendridae family. It is endemic to Australia, and was first described in 1916 by German naturalist Karl Kraepelin from material collected by Swedish zoologist and explorer Eric Mjöberg. It is a relatively small species, averaging 38 millimetres in length, with a pale brownish-yellow body, reddish-brown head, and variably coloured last segment and back legs. Its notable characteristics include short, 17-segmented antennae, mouthparts with 4 or 5 large outward-facing teeth, body segments with distinct median indentations, and varied leg features such as bristles at the base of claws on the first 20 pairs and 2 to 5 spines on the last pair.
Geomerinus is a monotypic genus of centipedes in the family Geophilidae. It was described by French myriapodologist Henry Wilfred Brolemann in 1912. Its sole species is Geomerinus curtipes, originally described as Geophilus curtipes by Erich Haase in 1887. It is endemic to Australia.
Tuoba is a genus of 17 species of centipedes, in the family Geophilidae. This genus was described by American biologist Ralph Vary Chamberlin in 1920. These centipedes are found in coastal regions and islands in the Mediterranean and in the Atlantic, Pacific, and Indian oceans.
Tuoba laticeps is a species of centipede in the Geophilidae family. It is endemic to Australia, and was first described in 1891 by British zoologist Reginald Innes Pocock.
Tuoba sydneyensis is a species of centipede in the Geophilidae family. It was first described in 1891 by British zoologist Reginald Innes Pocock.
Australoschendyla albanyensis is a species of centipede in the Schendylidae family. It is endemic to Australia, and was first described in 1996 by R. E. Jones.
Tasmanophilus spenceri is a species of centipede in the family Zelanophilidae. This centipede is found only in New Zealand and has only 39 pairs of legs, the minimum number recorded in the family Zelanophilidae. This species reaches only 23 mm in length and is the smallest centipede in this family.
Schendylops ramirezi is a species of soil centipede in the family Schendylidae. This centipede is notable as the species with the fewest legs recorded in the order Geophilomorpha for each sex. This species is also the smallest in the genus Schendylops, reaching only 7 mm (0.28 in) in length.
Dinogeophilus is a genus of soil centipedes in the family Schendylidae. This genus contains only two species, Dinogeophilus pauropus and D. oligopodus, which range from 4.5 to 5.5 mm in length. These species are notable as the smallest not only in the order Geophilomorpha but also among all epimorphic centipedes. The species D. oligopodus is also notable as one of only six species of soil centipedes to feature only 29 pairs of legs and one of only two species to include females with only 29 pairs, the minimum number recorded for females in the order Geophilomorpha.
Schendyla antici is a species of soil centipede in the family Schendylidae. This species is notable as one of only six species in the order Geophilomorpha to feature centipedes with only 29 pairs of legs, which is also the minimum number recorded in the genus Schendyla. No other species in this genus features so few legs.
Mecophilus is a genus of soil centipedes in the subfamily Aphilodontinae, a clade formerly known as the family Aphilodontidae but now deemed a subfamily within the family Geophilidae. The species in this genus are among the smallest centipedes in the order Geophilomorpha, reaching only 8 mm in length. This genus is also notable for featuring the fewest legs in the subfamily Aphilodontinae. The species in this genus are found in the Atlantic Forest in south and southeastern Brazil.
Krateraspis is a genus of soil centipedes in the family Mecistocephalidae. Centipedes in this genus are found in Central Asia. This genus contains only two species, K. meinerti, with 45 pairs of legs, and K. sselivanovi, with 53 leg pairs. The species K. sselivanovi is notable for featuring 53 leg pairs without any intraspecific variation. This number of legs is rarely observed in the family Mecistocephalidae and also appears to be the maximum number evidently fixed by species in the class Chilopoda.
