Arctogeophilus Explained

Arctogeophilus is a genus of soil centipedes in the family Geophildae.[1] These centipedes are found in subarctic and temperate regions of Asia, North America, and western Europe.[2] The taxon Arctogeophilus was first proposed in 1909 by the Austrian myriapodologist Carl Attems as a subgenus within the genus Geophilus.[3] The French zoologist Henri Ribaut elevated Arctogeophilus to the rank of genus in 1910.[4]

Description

Species in this genus have markedly elongate heads. The side pieces of the labrum almost touch in the middle, with the intermediate part inconspicuous. The forcipule is elongate, especially the first article, which features a distal denticle. The ultimate article of the forcipule features a basal denticle. The sterna have no carpophagus structures and usually no clusters of pores. The ultimate legs are longer than the penultimate legs, and the basal part of each of the ultimate legs usually features scattered pores.[5]

Centipedes in this genus range from less than 2 cm to 5 cm in length and have 35 to 69 pairs of legs. The Russian species Arctogeophilus sachalinus and the German species A. wolfi are notable for their small sizes, measuring only 11 mm and 14 mm in length, respectively.[6] [7] The North American species A. melanonotus is notable for its large size, reaching 50 mm in length. The Russian species A. macrocephalus can have as few as 35 leg pairs,[8] the minimum number recorded in this genus. The North American species A. atopus can have as many as 69 leg pairs,[9] the maximum number recorded in this genus.
