The first list of the chilopod species is provided: 22 species in 14 genera, 8 families and 4 orders.

Cryptops doriae Pocock, 1891 and Scolopendra cingulata Latreille, 1829 are new to the fauna of Uzbekistan, while Polyporogaster porosa (Sseliwanoff, 1881) is new to Turkmenistan. Pachymerium ferrugineum (C.L. Koch, 1835) is new to the Sirdaryo Region, while Bothriogaster signata (Kessler, 1874) is formally new to the Qashqadaryo and Sirdaryo Regions of Uzbekistan. The full lists of the chilopod species from Uzbekistan and Turkmenistan are provided: 22 and 12 species, respectively.

The centipede fauna of the Dagestan comprises at least 19 species from 12 genera, 9 families, and 4 orders; 14 species are new to the regional list, including new to the fauna of northern Caucasus: Bothriogaster signata (Kessler, 1874), genus Bothriogaster Sseliwanoff, 1879, family Himantariidae, and Lithobius (L.) erythrocephalus C.L. Koch, 1847; or to the Caucasian fauna: Dignathodon microcephalus (Lucas, 1846), and genus Dignathodon Meinert, 1870. The most of the species are illustrated.

The order, family, genus and species of the house centipede are new to Asian Russia's list: Scutigeromorpha, Scutigeridae, Scutigera Lamark, 1801, and Scutigera coleoptrata (Linnaeus, 1758). All records of the species in the south of western Siberia appear to be associated with synanthropic habitats. Distributional remarks are provided, all currently reported findings being mapped as well.

A comprehensive redescription of the poorly known mecistocephalid genus Krateraspis Lignau, 1929 and its two species is provided, based on the examination of type material and new specimens, as well as the critical evaluation of all published information. Krateraspis is confirmed differing from all other Mecistocephalidae especially for a peculiar pattern of areolation and setation of the clypeus. Records from 24 localities indicate that Krateraspis is limited to a narrow area of Middle Asia, from the Western Tian-Shan to the western offshoots of Pamir Mountains. Two species are morphologically distinguishable: K. meinerti (Sseliwanoff, 1881) and K. sselivanovi Titova, 1975. They differ mainly in details of the clypeus and maxillae, in the pattern of forcipular denticles, and in the number of legs. Tygarrup asiaticus Verhoeff, 1930 is confirmed as a junior synonym of K. meinerti, and a lectotype is designated for the former.
