Arctogeophilus is a genus of soil centipedes in the family Geophildae. [1] These centipedes are found in subarctic and temperate regions of Asia, North America, and western Europe. [2] The taxon Arctogeophilus was first proposed in 1909 by the Austrian myriapodologist Carl Attems as a subgenus within the genus Geophilus . [3] The French zoologist Henri Ribaut elevated Arctogeophilus to the rank of genus in 1910. [4]

Description

Species in this genus have markedly elongate heads. The side pieces of the labrum almost touch in the middle, with the intermediate part inconspicuous. The forcipule is elongate, especially the first article, which features a distal denticle. The ultimate article of the forcipule features a basal denticle. The sterna have no carpophagus structures and usually no clusters of pores. The ultimate legs are longer than the penultimate legs, and the basal part of each of the ultimate legs usually features scattered pores. [5] [2] [6]

Centipedes in this genus range from less than 2 cm to 5 cm in length and have 35 to 69 pairs of legs. [2] [4] The Russian species Arctogeophilus sachalinus and the German species A. wolfi are notable for their small sizes, measuring only 11 mm and 14 mm in length, respectively. [7] [4] [8] The North American species A. melanonotus is notable for its large size, reaching 50 mm in length. [8] The Russian species A. macrocephalus can have as few as 35 leg pairs, [5] the minimum number recorded in this genus. [2] The North American species A. atopus can have as many as 69 leg pairs, [9] [8] the maximum number recorded in this genus. [2]

Pachymerium is a genus of centipedes in the family Geophilidae found mainly in the west Palearctic region and in south Africa. Centipedes in this genus feature an elongate head, scattered coxal pores, and sternal pores in a pair of anterior groups and a posterior transverse band; the forcipular coxosternite is broad, and the ultimate article of the forcipule has a prominent basal denticle.

<span class="mw-page-title-main">Himantariidae</span> Family of centipedes

Himantariidae is a monophyletic family of centipedes in the order Geophilomorpha and superfamily Himantarioidea, found almost exclusively in the Northern Hemisphere. Centipedes in this family feature a short head with a concave labral margin bearing a row of denticles, a single dentate lamella and some pectinate lamellae on each mandible, second maxillae with strongly tapering telopodites and slightly spatulate claws, and a stout forcipular segment with short forcipules and a wide tergite; the ultimate legs usually have no pretarsus, and the female gonopods are distinct and biarticulate.

<i>Geophilus</i> Genus of centipedes

Geophilus is a large, heterogeneous genus of soil centipedes in the family Geophilidae largely considered to be synonymous with Brachygeophilus. The generic name first appeared in Brewster's Edinburgh Encyclopaedia in 1814 as Geophilus electricus. This genus has a Holarctic distribution.

Steneurytion is a genus of centipedes in the family Geophilidae. This genus was first described by Austrian myriapodologist Carl Attems in 1909. These centipedes are found in Australia, New Zealand, and Hawaii.

<i>Ribautia</i> Genus of centipedes

Ribautia is a genus of centipedes in the family Geophilidae. This genus was described by French myriapodologist Henry Wilfred Brolemann in 1909. Centipedes in this genus are found in South America, tropical Africa, Madagascar, the Arabian peninsula, Australia, New Zealand, and Melanesia.

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.

Mecistocephalus is the largest genus of centipedes in the family Mecistocephalidae, with about 140 species. This genus is among the most diverse and widespread of all the genera in the order Geophilomorpha. The British entomologist George Newport first proposed this genus in 1843 to contain a group of centipedes marked by an unusual elongation of the head.

Schendyla is a genus of soil centipedes in the family Schendylidae. These centipedes are found in the west Palearctic region. This genus was described by Danish entomologists Vilhelm Bergsøe and Frederik Vilhelm August Meinert in 1866. This genus now includes more than 20 species.

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.

Pectiniunguis is a genus of centipedes in the family Schendylidae. This genus was described by American naturalist Charles Harvey Bollman in 1889. Centipedes in this genus feature second maxillae with claws fringed by two rows of filaments, transversally elliptical sternal pore-fields on almost all trunk segments, two pores on each coxopleuron, and ultimate legs without claws.

Marsikomerus is a genus of centipedes in the family Schendylidae. It was described by Austrian myriapodologist Carl Attems in 1938. Species in this genus are found in Mexico and in the United States.

Nesomerium is a monotypic genus of centipedes in the family Geophilidae. It was described in 1953 by American myriapodologist Ralph Vary Chamberlin. The sole species is Nesomerium hawaiiense Chamberlin, 1953. Since the original description of this species based on a single specimen, no other specimens have been referred to this species or this genus, and some authorities express doubts about the validity of these taxa and their placement in the family Geophilidae.

Geophilus oligopus is a species of soil centipede in the family Geophilidae. This centipede is found in several European countries, including Austria, the Czech Republic, Italy, Croatia, Slovenia, Bosnia and Herzegovenia, and Romania. Although this centipede has been described as having an Alpine-Dinaric distribution, this species has also been found in the Carpathian mountains and may be more widespread than previously thought.

Dicellophilus carniolensis is a species of soil centipede in the family Mecistocephalidae. This centipede is well known and found in central Europe. This species features 43 pairs of legs, a number rarely found in the family Mecistocephalidae and recorded in only one other genus in this family: In the genus Tygarrup, an undescribed species found in the Andaman Islands also has 43 leg pairs.

Mecistocephalus angusticeps is species of soil centipede in the family Mecistocephalidae. This centipede is found in Kenya and Seychelles. This species features only 47 pairs of legs rather than the 49 leg pairs usually observed in the genus Mecistocephalus.

Arctogeophilus glacialis is a species of soil centipede in the family Geophildae. This centipede is found in Russia, Alaska, and Canada. This species was first described in 1909 by the Austrian myriapodologist Carl Attems as the type species for the taxon Arctogeophilus, which was originally described as a subgenus of the genus Geophilus but was elevated to the status of genus in 1910 by the French zoologist Henri Ribaut.

Escaryus is a genus of soil centipedes in the family Schendylidae. These centipedes are notable as schendylids adapted to colder temperatures and restricted to cool climates and high latitudes. With more than 30 species, this genus is easily the largest group of such centipedes in the family Schendylidae. Most schendylids are limited to tropical or subtropical regions.

Alloschizotaenia is a genus of soil centipedes in the family Geophilidae. This genus contains only three valid species. Centipedes in this genus are found in central and east Africa.

Alloschizotaenia bipora is a species of soil centipede in the family Geophilidae. This centipede is found in Rwanda and the Democratic Republic of the Congo. This species was first described in 1952 by the Austrian myriapodologist Carl Attems.
