Centipedes are predatory representatives of the group Myriapoda and important components of the soil and leaf-litter fauna. The first pair of trunk appendages is modified into venom-injecting maxillipeds in all centipedes. The number of trunk appendage pairs varies between the different groups of centipedes, from 15 pairs as apparently ancestral (plesiomorphic) condition, up to 191 pairs. The last pair of trunk legs can be used for different tasks in centipedes, e.g. mechano-sensation, defense, or stridulation. Many morphological details are also known from fossil centipedes, but especially the oldest fossils are often fragmentary and the fossil record in general is rather scarce. Especially the late appearance of lithobiomorphans in Cenozoic ambers is notable, though some not formally described lithobiomorph-like specimens from Cretaceous amber from Myanmar have been published. We present here a new specimen from Cretaceous Kachin amber, Myanmar with a lithobiomorph-type of morphology, Lithopendra anjafliessae gen. et sp. nov. The very large ultimate leg appears to have been used for defence and is, in relative proportions, larger than in any known lithobiomorphan, only comparable to that in scolopendromorphans. With this, the specimen presents a mixture of characters, which are in the modern fauna only known from two different centipede groups. We discuss the implications of this new fossil, also concerning events of convergence in this lineage.

Schendyla antici sp. nov., a dwarf geophilomorph from the Mt. Medvednik (Western Serbia, Balkan Peninsula), is described and illustrated based on the specimens extracted from the soil samples. A detailed comparison with all species within the genus is provided. The new species has the lowest number of leg-bearing segments within the genus Schendyla Bergsøe & Meinert, 1866, and one of the lowest in the order Geophilomorpha in general.

The paper provides new data and a synthesis on scolopendromorph centipedes of the island of Martinique. Some studied taxa are provided with new illustrated descriptions or diagnoses. Cryptops (Trigonocryptops) amicitia n. sp. is described and its systematic position discussed. Some data on the taxonomy of the subgenus Trigonocryptops Verhoeff, 1906 and a renewed list of its species are given. A complete checklist of the scolopendromorph centipedes of Martinique is presented; for some of the studied species, updated distributions and brief ecological data are provided. New data on some characters used in scolopendromorph taxonomy are provided.
