Orphnaeus is a genus of centipedes in the family Oryidae. This genus was described by Danish entomologist Frederik Vilhelm August Meinert in 1870. [1] [2] Centipedes in this genus are found in tropical regions. [3]
Centipedes in this genus have short ultimate legs, range from 3 cm to 13 cm in length, and have 53 to 131 pairs of legs. [3] The minimum number of legs in this genus (53 pairs) appears in the species Orphnaeus bevilabiatus ; the maximum number (131 pairs) appears in the species O. madegassus. [4]
There are 14 valid species: [2]
Pachymerium is a genus of centipedes in the family Geophilidae. Centipedes in this genus feature elongate heads, sternal pores in a pair of anterior groups and a posterior transverse band, and scattered coxal pores; the forcipular coxosternite is broad, and the ultimate article of the forcipule has a conspicuous basal denticle. These centipedes range from about 2 cm to about 8 cm in length and have 37 to 79 pairs of legs. The Chilean species Pachymerium armatum measures only 20 mm in length and has only 37 leg pairs, the minimum number observed in this genus. The Russian species P. minutum is also notable for its small size and its modest number of legs. The Portuguese species P. coiffaiti is notable for its large size and many legs. Females of the large Turkish species P. serratum can reach 78 mm in length and have as many as 79 leg pairs, the maximum number observed in this genus. This genus contains the following species:
Himantarium is a genus of centipedes in the family Himantariidae. Centipedes in this genus feature a swollen trunk that is posteriorly stout, subcircular sternal pore-fields on almost all trunk segments, much inflated coxapleura completely covered with scattered pores, and a very small metasternite on the ultimate leg-bearing segment; each mandible has a robust dentate lamella and few pectinate lamellae. These centipedes range from 10 cm to 20 cm in length, have from 87 to 179 pairs of legs, and are found in the Mediterranean region. Both the minimum and the maximum number of legs in this genus appear in the species Himantarium gabrielis, which exhibits a striking degree of intraspecific variation in leg number.
Oryidae is a monophyletic family of soil centipedes belonging to the superfamily Himantarioidea.
Orphnaeus brevilabiatus is a species of centipede in the family Oryidae.
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.
Strigamia is a genus of soil centipedes in the family Linotaeniidae. Members of this family can be identified by their anteriorly tapering bodies, the extra claw on the forcipules, scattered coxal pores, and the distinctly swollen ultimate legs of the males. There are at least 50 described species in Strigamia. Centipedes in this genus can reach 15 cm in length and can have as few as 31 pairs of legs or as many as 83 leg pairs. The species S. hoffmani is notable for its small size as well as for a small number of legs. Other species with notably few legs include the Siberian species S. sibirica and the Romanian species S. lutea.
Sepedonophilus is a genus of three species of centipedes in the family Geophilidae. This genus is endemic to Australia, and was first described by Austrian myriapodologist Carl Attems in 1909. Centipedes in this genus feature scattered coxal pores and have no sternal pores; the lateral parts of the labrum almost touch medially, and the intermediate part is inconspicuous; the coxosternite of the second maxillae have peculiar anterior projections. These centipedes range from about 2 cm to 5 cm in length and have 49 to 79 pairs of legs. The smallest species in this genus, Sepedonophilus hodites, measures only 18 mm in length and has only 49 leg pairs, the minimum number recorded in this genus, whereas the largest species, S. perforatus, measures 50 mm in length and has 79 leg pairs, the maximum number recorded in this genus.
Steneurytion is a genus of centipedes in the family Geophilidae. It was first described by Austrian myriapodologist Carl Attems in 1909.
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.
Ribautia is a genus of centipedes in the family Geophilidae. It 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. It was described by American biologist Ralph Vary Chamberlin in 1920.
Mecistocephalus is a genus of centipedes in the family Mecistocephalidae. It was described by British entomologist George Newport in 1843.
Schendyla is a genus of centipedes in the family Schendylidae. It was described by Danish entomologists Vilhelm Bergsøe and Frederik Vilhelm August Meinert in 1866. Centipedes in this genus feature only a few spines on the claws of the second maxillae, two pores on each coxopleuron, and ultimate legs without claws. These centipedes range from 1 cm to about 4 cm in length and have from 31 to 57 pairs of legs. The species Schendyla verneri is notable for its small size and for having only 31 leg pairs, the minimum recorded in this genus. Other small species with notably few legs in this genus include S. walachica, S. dalmatica, S. dentata, S. gracillima. and S. armata. The species S. monoeci measures only 17.5 mm in length but can have from 51 to as many as 57 leg pairs, the maximum number found in this genus. Descriptions of the species S. vizzavonae report no more than 51 leg pairs, but this species is notable for its relatively large size, reaching 45 mm in length.
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.
Ityphilus is a genus of centipedes in the clade Ballophilidae. It was described by American myriapodologist Orator Fuller Cook in 1899. Centipedes in this genus feature distinctly club-like antennae, well marked sclerotized lines on the forcipular coxosternite, and two pores on each coxopleuron. These centipedes range from about 1 cm to about 9 cm in length and have 41 to 113 pairs of legs. The dwarf species Ityphilus donatellae ranges from 8.5 to 11 mm in length and can have as few as 41 leg pairs, the minimum number found in this genus. The large species I. grandis can reach 93 mm in length and have as many as 113 leg pairs, the maximum number found in the clade Ballophilidae.
