Stigmatogaster is a genus of centipedes in the family Himantariidae. Centipedes in this genus feature a relatively slender trunk, transversally slightly elongate sternal pore-fields on almost all trunk segments, and unusual lateral furrows on some trunk metasternites; most coxal organs open into a dorsal pouch covered by the metatergite. These centipedes range from 5 cm to 10 cm in length, have 83 to 111 pairs of legs, and are found in the Mediterranean region. This genus contains the following species:
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.
Himantarium gabrielis is a species of centipede in the family Himantariidae.
Aspidopleres is an African genus of centipedes belonging to the family Oryidae. Centipedes in this genus feature sternal pores in four broad groups on each metasternite, very short ultimate legs, and uniarticulate female gonopods. These centipedes range from 11 cm to 12 cm in length, have 87 to 105 pairs of legs, and are found in southwest Africa.
Mecistocephalidae is a monophyletic family of centipedes in the order Geophilomorpha. It is the only family in the suborder Placodesmata. Most species in this family live in tropical or subtropical regions, but some occur in temperate regions. This family is the third most diverse in the order Geophiliomorpha, with about 170 species, including about 130 species in the genus Mecistocephalus.
Geophilus is a large, heterogeneous genus of soil centipedes in the family Geophilidae largely considered to be synonymous with Brachygeophilus. This genus is a mostly holarctic and characterized by a claw-shaped ultimate pretarsus, anterior porefields, complete or nearly complete coxo-pleural sutures at the prosternum, and incomplete chitin-lines. Centipedes in this genus feature slightly elongate heads and labral intermediate parts with tubercles, the forcipules are usually poorly elongate with a single small tubercle at the base of each tarsungulum, and the anterior trunk metasternites usually have an anterior medial socket and a posterior transversally elongate pore-field. The generic name first appeared in Brewster's Edinburgh Encyclopaedia in 1814 as Geophilus electricus.
Schendylidae is a family of centipedes in the order Geophilomorpha.
Tygarrup is a genus of centipedes in the family Mecistocephalidae, found mainly in southeast Asia and from the Seychelles to Hawaii. Although species in this genus can have either 43 or 45 leg-bearing segments, most of these species have 45 leg pairs. An undescribed Tygarrup species found in the Andaman Islands has 43 leg pairs. Centipedes in this genus are sometimes melanised in patches, and sternal glands are present the males of most species. These centipedes range from 2 cm to 6 cm in length. Tygarrup javanicus is one of the smallest of the mecistocephalid species and has become an invasive in greenhouses in Europe.
Diphyonyx is a genus of soil centipedes in the family Geophilidae found in the Palearctic region. They are notable for the unusually shaped claws on the anterior part of the trunk, which are swollen and have anterior spurs enlarged into elongate projections. Centipedes in this genus have a forcipular coxosternite with a pair of anterior tubercles and feature no sternal pores. Most coxal organs open into a single pit on each coxopleuron. These centipedes range from 4 cm to 6 cm in length and have 65 to 81 pairs of legs.
Queenslandophilus is a genus of centipedes in the family Geophilidae. It was described by German myriapodologist Karl Wilhelm Verhoeff in 1925. Centipedes in this genus feature second maxillae with sclerotized ridges on the coxosternite, no sternal pores, and coxopleura many scattered pores; the lateral parts of the labrum almost touch medially, and the ultimate legs most often have claws. These centipedes range from 1 cm to 6 cm in length, have 37 to 75 pairs of legs, and are found in Australia, Japan, and North America. The Japanese species Queenslandophilus monoporus and Q. macropalpus are notable for their small sizes, measuring only 10 mm and 15 mm in length, respectively. The species Q. elongatus, found in California, is notable for its large size, ranging from 40 mm to 63 mm in length. The species Q. macropalpus has only 37 leg pairs, the minimum number recorded in this genus, whereas Q. elongatus has 73 to 75 leg pairs, the maximum number recorded in this genus.
Tuoba is a genus of 17 species of centipedes, in the family Geophilidae. It was described by American biologist Ralph Vary Chamberlin in 1920.
Zelanophilus is a genus of three species of centipedes, in the family Zelanophilidae. This genus was described by American biologist Ralph Vary Chamberlin in 1920. Centipedes in this genus are found in Australia and New Zealand.
Mecistocephalus is a genus of centipedes in the family Mecistocephalidae. It was described by British entomologist George Newport in 1843.
Australoschendyla is a genus of centipedes in the family Schendylidae. It was described by R. E. Jones in 1996. Centipedes in this genus feature claws on the second maxillae fringed by a single row of filaments, short forcipules, subcircular sternal pore-fields, one or two pores on each coxopleuron, and ultimate legs without claws. These centipedes range from 1 cm to 2 cm in length, have 41 to 47 pairs of legs, and are found in west Australia.
Maoriella is a genus of centipedes in the family Geophilidae. It was described by Austrian myriapodologist Carl Attems in 1903. Species in this genus are found in New Zealand, Australia, and Tahiti.
Gonibregmatus is a genus of centipedes in the family Gonibregmatidae. It was described by British entomologist George Newport in 1843.
Pectiniunguis is a genus of centipedes in the family Schendylidae. It 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. These centipedes range from 16 mm to 67 mm in length, have 35 to 73 pairs of legs, and are found in the tropical and subtropical regions of the Americas, Fiji, and west Africa. The African species Pectiniunguis minutus is notable not only for being the smallest in this genus but also for having as few as 35 leg pairs, the minimum number in this genus. The Brazilian species P. ducalis is notable not only for being the largest in this genus but also for having as many as 73 leg pairs, the maximum number in this genus.
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.
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.
