Three new species of the genus Newportia Gervais, 1847 from Colombia are described and illustrated. They were found in the cloud forests of the eastern Andes and in the rainforests of the biogeographical Choc, ecosystems where the centipede fauna has been little studied. Newportia (Newportia) florezi sp. nov. differs from other Newportia species in the arrangement of the spinous processes on the prefemur of the ultimate legs, while Newportia (Newportia) anopla sp. nov. has a coxopleuron without any trace of a coxopleural process and possesses an atypically small forcipular coxosternite. Newportia (Newportia) tequendama sp. nov. is morphologically similar to Newportia pusilla Pocock, 1893, but differs in having an undivided tarsus 2 in the ultimate legs and the arrangement of the spinous processes on the prefemur and femur. An identification key for the Colombian species of Newportia is provided.

Scolopendra arthrorhabdoides Ribaut, 1913 is redescribed based on fresh material. Its taxonomic status is evaluated and compared with Scolopendra armata Kraepelin, 1903 and Scolopendra alternans Leach, 1816. The geographical distribution of S. arthrorhabdoides is also revised. Scolopendra armata is reported from Colombia for the first time.

This study presents an updated list of centipedes of the orders Scutigeromorpha and Scolopendromorpha from Colombia based on data from the literature, the World Catalogue of Centipedes (CHILOBASE), and specimens examined in museum collections. Four families, nine genera, 37 species and four subspecies are listed. One species belongs to Scutigeromorpha, and 36 species and four subspecies to Scolopendromorpha. Eleven species and four subspecies of scolopendromorphs are recorded for the first time from Colombia. Newportia Gervais, 1847 is the most diverse genus with 12 species and three subspecies. Six species of Scolopendromorpha are endemic. Three species-Otostigmus inermis Porat, 1876, O. scabricauda (Humbert & Saussure, 1870) and Cryptops iheringi Brölemann, 1902-are deleted from the fauna of Colombia. The Andean Región in Colombia has the most records of Scutigeromorpha and Scolopendromorpha. Maps showing the geographical distribution are given for the orders, genera, and some species.
