Three new species of bristletails of the families Meinertellidae and Machilidae (Archaeognatha) from Ukraine and Southern Russia

Abstract

Two new species of Machilinus Silvestri, 1905 (M. petrophilus Kaplin, sp. nov., M. obscurus Kaplin, sp. nov.) from Ukraine and one new species of Charimachilis Wygodzinsky, 1939 (C. rostoviensis Kaplin sp. nov.) from Southern Russia are described. The new species of Machilinus belong to the subgenus Machilinus s. str. with 1 + 1 eversible vesicles on urocoxites II–VII, and urostyli with apical spines; to the group “rupestris” with 2nd and 3rd articles of male maxillary palpus without ventral spines (M. obscurus sp. nov.), and with spines on these articles (M. petrophilus sp. nov.). Machilinus petrophilus sp. nov. differs from M. rocai Bach, 1975 in the color and ratio of length to width of compound eyes, the presence of numerous short chaetae on the clypeus, the structure of the lateral apophysis on the 2nd article of the male maxillary palpus, and the number of ventral spines on the legs. Machilinus obscurus sp. nov. differs from the other species of the group “rupestris” in the color of compound eyes, the presence of numerous short chaetae on the male frons and clypeus, and in other features. Charimachilis rostoviensis sp. nov. (Machilidae) most closely resembles C. ukrainensis Stach, 1958. Charimachilis rostoviensis sp. nov. differs from C. ukrainensis in the shape of posterior angle of urosternites, and ratios of lengths of urostyli and urocoxites.

A new species of bristletails of the genus Charimachilis (Microcoryphia: Machilidae) from Crimea

“…from the vicinity of the city Staryi Krym is described and illustrated. It is compared with parthenogenetic congeners from the Kiev region of Ukraine (C. ukrainensis Stach, 1958), as well as from Rostov (C. rostoviensis Kaplin, 2020) and Belgorod (C. morozovi Kaplin, 2019) regions of the Russian Federation. C. taurica sp.n.…”

Assessing the Diversity of Ant-Associated Silverfish (Insecta: Zygentoma) in Mediterranean Countries: The Most Important Hotspot for Lepismatidae in Western Palaearctic

“…Then, Kaplin [33] described two new species of Neoasterolepisma from Turkmenistan (N. deserticola and N. psammophilum) that could be related to L. escherichi (even being conspecific). Kaplin [34] considered that N. wasmanni could occur in Krasnodar (near Crimea), but without providing records. With this situation, we think that L. escherichi should be considered as species inquirenda and that the eastern limit of the distribution of N. wasmanni reaches the Black Sea in Crimea.…”

A new species of the bristletail genus Charimachilis Wygodzinsky, 1939 (Microcorypha: Machilidae) from Eastern Ukraine

“…Southwestern Palaearctic genus Charimachilis Wygodzinsky, 1939 (Microcoryphia: Machilidae, Machilinae) consists of 15 described species: C. palaestinensis Wygodzinsky, 1939(Palestina), C. wahrmani Wygodzinsky, 1959, C. caucasica Kaplin, 2019 (Russia, Krasnodar region), C. abchasica Kaplin, 1999 (Abkhazia), C. manfredoniae Kaplin, 1999 (Italy), C. egatensis (Bach de Roca, 1983) (Italy), C. melitensis (Stach, 1958(Malta), C. orientalis (Silvestri, 1908 (Greece), C. dentata Wygodzinsky, 1941(Greece), C. relicta Janetschek, 1954(Italy, Croatia, Austria, Greece), C. armata Stach, 1958(Bulgaria), C. ukrainensis Stach, 1958, C. morozovi Kaplin, 2019 (Russia, Belgorod region), C. rostoviensis Kaplin, 2020 (Russia, Rostov region), and C. taurica Kaplin, 2021 (Crimea) (Kalin, 2019;Kaplin & Martynov, 2020;Kaplin, 2021). Most species of this genus are parthenogenetic.…”
