Schendylops is the largest genus of centipedes in the family Schendylidae, containing more than 60 species.{{Cite web |title=ITIS - Report: Schendylops |url=https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=1093364#null |access-date=2024-06-05 |website=www.itis.gov}}{{Cite book |last1=Bonato |first1=Lucio |url=https://www.worldcat.org/oclc/812207443 |title=The Myriapoda.

These species live in diverse habitats, ranging from sea level (e.g., in the Caribbean region) to high altitudes, e.g., at {{Cvt|4,500|m}} above sea level in the Andes mountains.

Description

Centipedes in this genus feature two rows of filaments on the claws of the second maxillae, sternal pore fields on leg-bearing segments, two pores on each coxopleuron, and ultimate legs with seven segments but no claw. The pleurites of the second maxillae are not fused to the coxosternum. Species in this genus range from {{cvt|1|to|7|cm}} in length and have from 27 to 87 pairs of legs.

This genus is notable for including the two species that feature the fewest legs (27 pairs) in the order Geophilomorpha. Both of these species are found in Brazil: males in the species Schendylops ramirezi have only 27 pairs of legs, while females have 29, and males in the species S. oligopus have 27 or 29 (usually 29), while females have 31.{{Cite journal |last=Pereira |first=Luis Alberto |date=2013-01-01 |title=Discovery of a second geophilomorph species (Myriapoda: Chilopoda) having twenty-seven leg-bearing segments, the lowest number recorded up to the present in the centipede order Geophilomorpha |journal=Papéis Avulsos de Zoologia |language=en |volume=53 |issue=13 |pages=163–185 |doi=10.1590/S0031-10492013001300001 |issn=1807-0205 |doi-access=free |hdl-access=free |hdl=11336/3449}} Furthermore, S. ramirezi is one of only two species in this order in which females have only 29 leg pairs (the other species, Dinogeophilus oligopodus, has 29 in each sex). Both S. ramirezi and S. oligopus are also notable for their small sizes, reaching only 7 mm and 10 mm in length, respectively.

Females of the African species S. caledonicus have from 81 to as many as 87 pairs,{{Cite journal |last=Pereira |first=Luis Alberto |last2=Minelli |first2=Alessandro |date=2001 |title=A re-description of the South African centipede Schendylops caledonicus (Chilopoda Geophilomorpha Schendylidae) |url=https://sedici.unlp.edu.ar/handle/10915/156523 |journal=Bolletino della Società Entomologica Italiana |language=en |volume=133 |issue=1 |pages=13-25 [20, 22]}} the maximum recorded in this genus.
