Geophilus erzurumensis is a species of soil centipede in the family Geophilidae found only in Erzurum, Turkey, which it is named after. [1]
G. erzurumensis was originally placed in the genus Brachygeophilus based on its lack of sternal pores. [2] It may be a synonym of Pachymerium ferrugineum , along with Geophilus orientis , G. eudontus , and G. elazigus . [3]
The Geophilidae are a polyphyletic, cosmopolitan family of soil centipedes in the superfamily Geophiloidea containing the mostly defunct clades Aphilodontidae, Dignathodontidae, Linotaeniidae, Chilenophilinae, and Macronicophilidae.
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.
Schendylidae is a family of centipedes in the order Geophilomorpha.
Geophilus electricus is a species of soil centipede in the family Geophilidae found across temperate Europe, especially Britain and Ireland. Originally discovered and named Scolopendra electrica in 1758, it was later moved to its own genus, Geophilus. As the first species described in this genus, it is considered by some to be the type species. It is yellowish-orange in color and can grow up to 45 millimeters, with 55 to 75 leg pairs, a distinct carpophagus fossae on the anterior sternites, and a distinctive arrangement of the coxal pores of the last leg pair. Like many geophilomorphans, G. electricus has been known to glow in the dark, most likely as a defensive maneuver.
Geophilus impressus is a species of soil centipede in the family Geophilidae found all over Europe, and has also been recorded in North Africa. It lives frequently in endogean habitats; in Sardinia it's found mostly in Quercus ilex woods, but also in Mediterranean shrub, open habitats, and maquis. It lives anywhere from sea level to 1700 meters above it, sometimes in caves.
Geophilus gavoyi is a species of soil centipede in the family Geophilidae. It is closely related to both Geophilus aetnensis and its junior synonym G. evisensis; it's considered by some to be a synonym of G. evisensis. It's found under stones in northern Asia and western Europe, especially France and England. It grows to between 23 and 35 millimeters in length and has between 39 and 43 leg pairs in males and 41–45 in females. In the since debunked elongata subspecies it was said to vary from between 49 and 55 leg pairs in males and between 51 and 57 in females. As described in 1964, it has well-developed sternal grooves, longer legs than G. aetnensis, and normal claws in the anal legs.
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 anonyx is a species of soil centipede in the family Geophilidae found in Oregon. It was originally placed in the genus Brachygeophilus based on the lack of sternal pores, a character shared with the type species B. truncorum, however it was later moved to Geophilus.
Diphyonyx is a genus of soil centipedes in the family Geophilidae found in the Palearctic region. They are notable for the unusually shaped claws on the anterior part of the trunk, which are swollen and have anterior spurs enlarged into elongate projections. Centipedes in this genus range from 4 cm to 6 cm in length and have 65 to 81 pairs of legs.
Diphyonyx conjungens, formerly Geophilus conjungens, is a species of soil centipede in the family Geophilidae that has been recorded in the Balkan Peninsula, Anatolia, the southern Sporades islands, the most eastern parts of Turkish Armenia, the Pontic and Tauric mountains, and Crimea. It grows up to 60 millimeters long and bears 69–81 leg pairs in females, 67–79 in males, as well as 1–2 stout tubercles and 2–4 slender filaments on the mid-part of the labrum, an absence of condyles between the anterior trunk sterna, and a single, isolated pore on each coxo-pleuron.
Diphyonyx garutti, formerly Brachygeophilus sukacevi garutti, is a species of soil centipede in the family Geophilidae found in the most western part of the Caucasus range, north of the Black Sea. According to the original description, this species is characterized by 2–4 slender filaments on the mid-part of the labrum, condyles between the anterior trunk sterna, and a single, isolated pore on each coxo-pleuron. Since the original description based on 23 specimens in 1960, this species has not been recorded again.
Diphyonyx sukacevi, formerly Brachygeophilus sukacevi, is a species of soil centipede in the family Geophilidae found in the most western part of the Caucasus range and the Manych valley north of the Caucasus. This species can reach 45 mm in length and is characterized by its 65–81 leg pairs, 5–7 slender filaments on the mid-part of the labrum, condyles between the anterior trunk sterna, and the lack of a single, isolated pore on each coxo-pleuron.
Geophilus richardi is a species of soil centipede in the family Geophilidae found in France, Italy, and the Ionian Islands. Females of this species have 33 pairs of legs; males have 29 or 31. This species is one of only two in the family Geophilidae to include centipedes with as few as 29 leg pairs. This species grows up to 10 millimeters long, has no carpophagus pit or pore-fields, and has a gradually tapering, curved pretarsus of the second maxillae. G. richardi lacks typical ventral pores between 2–4mm. The sternites instead bear a small number of pores between 0.5–1mm that differ from micropores, which are unbounded by a cuticular ring. These are possibly the remnants of typical ventral pores, their smaller size being a byproduct of overall miniaturization.
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 bosniensis is a species of soil centipede in the family Geophilidae endemic to Bosnia and Herzegovina. It grows up to 30 millimeters and has 75 leg pairs, as well as sternites unseparated in the median but with a suture line, and sternal pore areas in the trunk segments only. Overall, the identity and phyletic position of this centipede are uncertain.
Geophilus brevicornis is a species of soil centipede in the family Geophilidae found on the continental United States, ranging from New Orleans to Galveston and south Illinois. It's deep orange and grows up to 50 millimeters long, with a robust, almost cylindrical body, 55 or 57 leg pairs, a relatively small cephalic segment, generally smooth scuta with distinct scuto-spiscutal sutures, and mandibles each with a single rather large tooth.
Geophilus claremontus is a species of soil centipede in the family Geophilidae found in Claremont, California, after which it was named. It was incorrectly placed in the genus Brachygeophilus in 1929 by Attems, most likely based on the lack of sternal pores.
Australiophilus ferrugineus is a species of centipede in the Zelanophilidae family. It is endemic to New Zealand. It was first described in 1877 by New Zealand biologist Frederick Hutton. Since then, authorities have recognized two junior synonyms, deeming Geophilus huttoni a synonym in 1936 and Geophilus polyporus a synonym in 2014.
