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.
Arrup is a genus of centipedes in the family Mecistocephalidae, native to Europe and Asia as far as Japan. Centipedes in this genus feature small telopodites on the second maxillae, the head and forcipular segment are elongate, the clypeus is almost completely areolate, and the poison glands in adult males are often deep inside the forcipules. These centipedes range from 1 cm to 5 cm in length. All species in this genus have 41 leg-bearing segments. Most are soil-dwellers but Arrup akiyoshiensis is a troglobiont.
Geophilus arenarius is a species of soil centipede in the family Geophilidae. This centipede is found in Algeria. As part of the carpophagus species-complex, this species is closely related to both G. carpophagus and G. easoni.
Geophilus fucorum is a halophilic species of soil centipede in the family Geophilidae found in the French Mediterranean, Corsica, Italy, and Greece. Males of this species have 49 to 53 pairs of legs; females have 51 to 55.
Geophilus mordax, also called the pitted soil centipede, is a species of soil centipede in the family Geophilidae found in North America, especially Indiana, Arkansas, Louisiana, North and South Carolina, and Florida. It grows up to 50 millimeters in length, though it averages 25–40, has 49–53 leg pairs in males and 49–57 in females, and is bright red in color. G. mordax also bears 3–5 labral teeth, a short and robust apical claw of the second maxillae, an exposed prebasal plate, and a large, consolidated sacculi.
Geophilus virginiensis is a species of soil centipede in the family Geophilidae found in Virginia. It grows up to 50 millimeters in length, has 49–57 leg pairs, and is tawny yellow in color.
Geophilus ampyx is a species of soil centipede in the family Geophilidae found in North America, especially South Carolina. It grows up to 52 millimeters in length, though it averages 30–40, has 49–53 leg pairs in males and 51–55 in females, and is bright red in color. G. ampyx also bears five sclerotized and deeply pigmented labral teeth and a nearly entirely exposed prebasal plate. It's often confused with G. mordax, though it can be differentiated by the absence of sacculi.
Geophilus vittatus, also known as the diamondback soil centipede, is a species of soil centipede in the family Geophilidae widespread in North America and named for the dark band of diamond-shaped markings across its back. G. vittatus grows up to 52 millimeters in length, though it averages 25–40, and ranges from brown- to orange-yellow in color, with 49–53 leg pairs in females, 49–51 leg pairs in males, and a lack of consolidated carpophagus structures. It can be found under any debris on the forest floor, but mostly under loose bark and occasionally near the sea.
Geophilus bipartitus is a species of soil centipede in the family Geophilidae found in Japan. It grows up to 15 millimeters in length; the males have about 35 leg pairs, the females 39. It lives in Japanese white birch.
Geophilus sounkyoensis is a species of soil centipede in the family Geophilidae found in Japan. Its body is yellow in color and it grows up to 40 millimeters in length; the males have about 55 leg pairs, the females 57.
Geophilus bluncki is a species of soil centipede in the family Geophilidae found in San Remo, Italy. It grows up to 23 millimeters in length; the males have about 61 leg pairs. The uniform pore fields and long antennae resemble Arctogeophilus glacialis, formerly Geophilus glacialis.
Geophilus monoporus is a species of soil centipede in the family Geophilidae found in Tiba, Japan. It grows up to 18 millimeters in length; it's named for the single pore at the base of the final leg pair.
Geophilus dentatus is a species of soil centipede in the family Geophilidae found in Hokkaido. It's yellow in color, 25 millimeters in length, with 41-47 leg pairs and two clearly visible terminal pores. It's very similar to G. truncorum, but differs in the number of outer palpi on the 1st maxillae, the presence of denticles in the midpiece of the labrum, and the number of terminal pores.
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 punicus is a species of soil centipede in the family Geophilidae found in the Western Mediterranean, specifically Italy and North Africa (Tunisia). It's an epigeic species, though its habitat preferences are unknown apart from one record from caves, indicating it may also be a trogloxene. The original description of this species is based on male specimens with 43 pairs of legs.
Geophilus koreanus is a species of soil centipede in the family Geophilidae found in North Korea. It's yellow in color and grows up to 30 millimeters long, with 69 leg pairs, a clypeus rather longer than wide, filiform antennae, central part of the labrum with 8 teeth, maxilla completely fused without median suture, tergite bifurcate, final leg tarsus bipartite, and a clawed pratarsus. It's similar to G. strictus, though the latter differs by the middle part of the labrum bearing a large number of very small teeth, and the final hip bearing a large number of pores.
Geophilus brunneus is a species of soil centipede in the family Geophilidae found in Bloomington Township, Monroe County, Indiana. It grows up to 23mm long and has an olive brown body, deep orange head segment, and light orange caudal segment, as well as between 47 leg pairs and 49, pitted posterior coxae, one very small tooth on the mandibles, and generally enlarged caudal legs in the male. The scutum is irregularly punctate, somewhat anteriorly narrowed, and slightly broader in the female than the male; the episcutal sutures are plain and have a greener tinge than the rest of the back.
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.
Mecistocephalus ongi is a species of centipede in the Mecistocephalidae family. It was described in 1934 by Japanese myriapodologist Yosioki Takakuwa.
