Himantariidae

Himantariidae is a monophyletic family of centipedes in the order Geophilomorpha and superfamily Himantarioidea, [1] found almost exclusively in the Northern Hemisphere. [2] 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. [3]

These centipedes are very elongated with a high mean number of trunk segments (often greater than 100) and great variability in this number within species. [4] The number of leg-bearing segments in this family ranges from 47 to 181. [3] The maximum number of legs recorded in this family (181 pairs) appears in the species Chomatobius bakeri. [5] [6] The minimum number of legs recorded in this family (47 pairs) appears in the species Garriscaphus oreines, [7] [8]

<i>Himantarium</i> Genus of centipedes

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.

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.

Steneurytion morbosus is a species of centipede in the Geophilidae family. This species was first described in 1877 by New Zealand naturalist Frederick Hutton. Authorities would later deem Pachymeroides alter, Zelanion paucipes, and Zelanion similis to be junior synonyms. Some authorities do not include this species in the genus Steneurytion.

Tasmanophilus is a genus of two species of centipedes, in the family Zelanophilidae. It was described by American biologist Ralph Vary Chamberlin in 1920. Centipedes in this genus are found in Australia and New Zealand.

Australiophilus is a genus of two species of centipedes, in the family Zelanophilidae. This genus was described by German myriapodologist Karl Wilhelm Verhoeff in 1925. Centipedes in this genus are found in Australia and New Zealand.

Pachymerellus zygethus is a species of centipede in the Geophilidae family. It is endemic to Australia and New Zealand, and was first described in 1920 by American biologist Ralph Vary Chamberlin.

Tasmanophilus spenceri is a species of centipede in the Zelanophilidae family. It is endemic to New Zealand. It was first described in 1901 by British zoologist Reginald Innes Pocock. The species epithet spenceri honours British-Australian evolutionary biologist Baldwin Spencer.

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.

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.

Mecistocephalus ongi is a species of centipede in the Mecistocephalidae family. It was described in 1934 by Japanese myriapodologist Yosioki Takakuwa.

Mecistocephalus brevisternalis is a species of centipede in the Mecistocephalidae family. It was described in 1934 by Japanese myriapodologist Yosioki Takakuwa.

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.

Marsikomerus bryanus is a species of centipede in the Lithobiidae family. It was described in 1926 by American myriapodologist Ralph Vary Chamberlin.

Steneurytion hawaiiensis is a species of centipede in the Geophilidae family. It was described in 1953 by American myriapodologist Ralph Vary Chamberlin. This species is known from a single male specimen measuring 28 mm in length with 39 pairs of legs.

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.

Mecistocephalus waikaneus is a species of centipede in the Mecistocephalidae family. It was described in 1953 by American myriapodologist Ralph Vary Chamberlin. This species is yellow, has 49 pairs of legs, and can reach 30 mm in length.

Mecistocephalus spissus is a species of centipede in the Mecistocephalidae family. It was described in 1862 by American biologist Horatio Curtis Wood. This species is dark yellow-brown, has 45 pairs of leg, and can reach 70 mm in length.

Endoptelus is a monotypic genus of centipedes in the family Oryidae. This genus was described in 1939 by American myriapodologist Ralph Vary Chamberlin. Its sole species is Endoptelus papuicolens Chamberlin, 1939.

Mecistocephalus uncifer is a species of centipede in the Mecistocephalidae family. It was described in 1919 by Italian myriapodologist Filippo Silvestri. This species has 49 pairs of legs and can reach 65 mm in length.

Mecistocephalus glabridorsalis is a species of centipede in the Mecistocephalidae family. It was described in 1900 by Austrian myriapodologist Carl Attems. This species has 49 pairs of legs, can reach 85 mm in length, and is yellow with anterior segments and a head that are reddish brown.
