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.
Geophilus aetnensis is a species of soil centipede in the family Geophilidae found in Europe and northern Asia, excluding China. As described by Verhoeff in 1928, it grows up to 28 millimeters and has 53 leg pairs, 4 sensory setae each on the 2nd-4th front sternites, slightly notched maxillae, and very faint sternal pits on the thorax as well as poorly developed sternal grooves.
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 labrofissus is a species of soil centipede in the family Geophilidae found on the Balkan Peninsula. It's a poorly defined species of uncertain identity that was first described in Zoologische Jahrbücher. Abteilung für Systematik, Ökologie und Geographie der Tiere. The original description of this species is based on a male specimen measuring 26 mm in length with 59 pairs of legs.
Geophilus winnetui is a species of soil centipede in the family Geophilidae found in Iowa. It grows up to 48 millimeters long and has 55–63 leg pairs, a well-developed labrum with the middle part having short, strong teeth, pushed backwards by median side parts that almost meet; maxilla with 2 pairs of somewhat blunt external palpi; coxal process not separated, with a number of strong bristles; and presternites undivided and so long that successive sternites are separated.
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 rhomboideus is a species of soil centipede in the family, Geophilidae found in Japan. It grows up to 30 millimeters in length; the males have about 43 leg pairs, while the females have, 49.
Geophilus sounkyoensis is a species of soil centipede in the family Geophilidae. This centipede is found in Japan and Russia. This species can have either 55 or 57 pairs of legs and can reach 40 mm in length.
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 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 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.
Queenslandophilus is a genus of soil centipedes in the family Geophilidae. This genus was described by German myriapodologist Karl Wilhelm Verhoeff in 1925. These centipedes are found in Australia, Japan, and North America.
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.
Tuoba tiosianus is a species of centipede in the Geophilidae family, described in 1934 by Japanese myriapodologist Yosioki Takakuwa.
Mecistocephalus ongi is a species of centipede in the Mecistocephalidae family. It was described in 1934 by Japanese myriapodologist Yosioki Takakuwa.
Mecistocephalus capillatus is a species of centipede in the Mecistocephalidae family. It was described in 1935 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.
Marshallopus is a monotypic genus of centipedes in the family Oryidae. It was described by German myriapodologist Karl Wilhelm Verhoeff in 1937. The sole species is Marshallopus platypedatus.
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.
