<i>Geophilus</i> Genus of centipedes

Geophilus is a large, heterogeneous genus of soil centipedes in the family Geophilidae largely considered to be synonymous with Brachygeophilus. It is a mostly holarctic genus characterized by a claw-shaped ultimate pretarsus, anterior porefields, complete or nearly complete coxo-pleural sutures at the prosternum, and incomplete chitin-lines. The generic name first appeared in Brewster's Edinburgh Encyclopaedia in 1814 as Geophilus electricus.

Arrup is a genus of centipedes in the family Mecistocephalidae, native to Europe and Asia as far as Japan. 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 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 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 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.

Geophilus crenulatus is a species of soil centipede in the family Geophilidae found in a ravine above the Hemis monastery in India, 3525 meters above sea level. It was originally thought to be a subspecies of G. intermissus and named Geophilus intermissus var. crenulata. The original description of this species is based on a specimen measuring 22 mm in length with 57 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 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.
