0380D71CFFD5FFF891FCFE1C43F2FE98.taxon	etymology	Etymology. The species is named after its most characteristic feature, which appears to be unique to the genus, namely, the compound lobes in PAO; from Latin sectilis –– divided. Affinities. Micranurida sectilis sp. nov. shows a number of unusual features (Table 1), therefore being hardly comparable to any known species of the genus. For instance, the complex lobes in PAO is not known in any of the described congeners. The absence of a medial pair of prelabral setae has been noted only in M. rostrata Babenko, 2007 (Central Siberia). The strong reduction of tibiotarsal setae is also quite unusual: the presence of 12 – 12 – 11 setae is known only in three congeners, i. e., M. sensillata (Gisin, 1953), M. balta Fjellberg, 1998 (both from Europe), and M. potapovi (Russian Far East). A complete dorsal chaetotaxy with the presence of p 2 setae on all terga from Th. II to Abd. IV is not common either. It is not typical of most European species, but, besides M. sectilis sp. nov., it is also known in a number of Eastern Palaearctic congeners, for example, M. rostrata, M. russica, M. potapovi and M. distincta sp. nov. (see description below). All these species are easily distinguished from M. sectilis sp. nov. by other features, for example the absence (M. rostrata, M. potapovi and M. distincta sp. nov.) or fewer ocelli (M. russica).	en	Babenko, Anatoly, Shveenkova, Yulia, Potapov, Mikhail (2022): The genus Micranurida Börner, 1901 sensu Deharveng 1982 (Collembola Neanuridae, Pseudachorutinae) in the fauna of the Russian Far East.

0380D71CFFD0FFFB91FCFE7041C2FB5C.taxon	discussion	Remarks. The material from Anyuinski National Park, Khabarovsk Territory, contains one immature specimen which also lacks ocelli, has coarse granulation of the integument (but without prominent tubercles), six antennal sensilla, and strongly swollen sensilla on Th. II and Abd. IV. Unlike M. distincta sp. nov., it is characterized by the presence of seta i on Ant. IV, three ordinary setae and two sensory elements on the main part of the labium, more strongly reduced dorsal chaetotaxy without p 2 setae on the abdominal terga, and a complete set of tibiotarsal setae, i. e. altogether 19 – 19 – 18, respectively. Obviously, this is a different species, probably related to M. spirillifera Hammer, 1953, but additional material is necessary to describe it.	en	Babenko, Anatoly, Shveenkova, Yulia, Potapov, Mikhail (2022): The genus Micranurida Börner, 1901 sensu Deharveng 1982 (Collembola Neanuridae, Pseudachorutinae) in the fauna of the Russian Far East. Zootaxa 5188 (5): 489-500, DOI: https://doi.org/10.11646/zootaxa.5188.5.5
0380D71CFFD0FFFB91FCFE7041C2FB5C.taxon	etymology	Etymology. The name of the new species reflects its clear differences from congeners, from Latin distinctus – – distinct. Affinities. The genus Micranurida s. str. embodies only six species characterized by the presence of six sensilla (including sensillum S 2 sensu D’Haese) on Ant. IV, namely, M. spirillifera, M. retezatica Gruia & Harșia, 1990, M. bescidica Smolis & Skarżyński, 2004, M. rostrata, M. russica and M. potapovi. Most of them are easily distinguished by the number of tibiotarsal setae: 15 – 15 – 14 setae in M. distincta sp. nov., vs 12 – 12 – 11 in M. potapovi, 14 – 13 – 14 in M. rostrata, 14 – 14 – 14 in M. bescidica and 17 – 17 – 16 in M. spirillifera and M. russica (Table 1). This character is unknown only for M. retezatica, a European species characterized by elongated sensilla S 7 on the antennae, as well as the absence of p 2 setae on all terga. The presence of clearly defined fields of coarser granulation on all terga makes it easy to distinguish M. distincta sp. nov. from the vast majority of congeners. Perhaps the only exception is M. russica, described from the same region (a comparison with the latter species is given below). Taking into account the dorsal chaetotaxy of M. distincta sp. nov., in particular, the presence of p 2 setae not only on the thoracic, but also on the abdominal terga, it is comparable only to three Eastern Palearctic species of the above list, namely, M. rostrata, M. potapovi, and M. russica. Of these, the former two are eyeless, like M. distincta sp. nov., while M. russica has 1 + 1 ocelli. However, it is the latter species, whose main diagnostic feature (the fusion of two sensilla on the antennae) is almost unique to the genus (a similar fusion is known only in M. bescidica), that seems to be most close to M. distincta sp. nov. This assumption is mainly based on a high similarity of their dorsal chaetotaxy, in particular the anterior position of the p 2 setae on the terga and the location of all dorsal setae within the fields of enlarged granules. The only sound difference between the dorsal chaetotaxy of these two species lies in the presence of four ordinary chaetae (а 3, а 4, m 4 and p 4) in dorsolateral position on Th. II-III in M. russica (vs three such setae in M. distincta sp. nov., i. e. m 4 is absent), as well as 2 + 2 setae between sensilla on Abd. V in M. russica, vs 1 + 1 setae in M. distincta sp. nov. It is also noteworthy that these two species are not only very similar morphologically and inhabit the same region, but both can also occur in the same biotopes and even in the same soil sample. Nevertheless, in addition to the above-mentioned differences in dorsal chaetotaxy, the number of tibiotarsal setae, and the presence / absence of ocelli, there are several other subtle, but significant differences that indicate the extent of possible variation in some morphological structures. Thus, the new species lacks seta i on Ant. IV, which is present in the majority of related species, including M. russica. The absence of this seta is known only in M. bescidica and M. rostrata. Some reduction of setae in the basal parts of the labium (mentum and submentum) also deserves mention. Nothing similar seems to have previously been noted in the genus.	en	Babenko, Anatoly, Shveenkova, Yulia, Potapov, Mikhail (2022): The genus Micranurida Börner, 1901 sensu Deharveng 1982 (Collembola Neanuridae, Pseudachorutinae) in the fauna of the Russian Far East.

0380D71CFFD3FFF491FCFB3440BAFB14.taxon	discussion	Remarks. Three forms may be distinguished within this complex in the Russian Far East, all quite clearly separated both morphologically (see Table 1) and in habitat. The first one, being most consistent with the modern description of the European populations of M. pygmaea (Fjellberg 1998, p. 75), is mainly confined to the subalpine belt at altitudes over 1500 m. The second form (form A) is characterized by the presence of only 1 + 1 ocelli, the absence of colouration (except for the ocelli), slightly widened sensilla on Th. II and Abd. IV and 17 – 17 – 16 setae on the tibiotarsi, respectively (not only M-seta as in the first form, but also A 4 absent). Contrary to the first form, it occurs only in lower-mountain mixed and coniferous forests. There are also few specimens of the third form (form B) which differs from the second only in the complete absence of ocelli. It is likely that at least some of these « forms » represent isolated species, but taking into account the high variability of M. pygmaea described for European populations of this widespread species (Fjellberg 1998), as well as a large number of closely related European species that are rather poorly defined and difficult to identify (Fjellberg 1998, p. 77), the description of these Far Eastern forms as independent species seems to be premature.	en	Babenko, Anatoly, Shveenkova, Yulia, Potapov, Mikhail (2022): The genus Micranurida Börner, 1901 sensu Deharveng 1982 (Collembola Neanuridae, Pseudachorutinae) in the fauna of the Russian Far East.

0380D71CFFDCFFF491FCFAFC428EF844.taxon	discussion	Remarks. When describing M. russica, Smolis et al. (2012) stated that seta M present [on], setae A 3 and A 6 absent (p. 150) from the tibiotarsi of this species. However, in most described cases in Poduromorpha (see, for instance, Fjellberg, 1990, 1991) the reduction of tibiotarsal setae begins with the loss of seta M and one or both of the inner setae of distal whorl, i. e. A 4 and / or A 5. As Fjellberg (1998, p. 75) wrote, the tibiotarsi [in M. pygmaea] with 18 – 18 – 17 setae, seta M absent. … Juveniles and subadults may lack one or more of tibiotarsal setae T 3, T 4, A 4, A 5. Thus, the absence of setae A 3 and A 6 postulated for M. russica seems doubtful. Instead we believe that actually this species lacks setae M and A 4, which is more usual to the genus. The species appears to be rather widespread in the region under study. Its types originated from Primorskyi Kray, Khasan Area, Barabash [43 ° 11 ' N 131 ° 29 ' E], i. e. the southernmost part of Primorye, whereas one of the localities where we found this species (Zeya State Nature Reserve, Amur Region) is located more than 1200 km to the north-north-west.	en	Babenko, Anatoly, Shveenkova, Yulia, Potapov, Mikhail (2022): The genus Micranurida Börner, 1901 sensu Deharveng 1982 (Collembola Neanuridae, Pseudachorutinae) in the fauna of the Russian Far East.

It has been found by us about 100 km northwest of the type locality (Primorskyi Kray, Partisansk Region, Ekaterinovka [42 ° 55 ' N 133 ° 02 ' E]), and its morphology is fully consistent with the original description (see also a note to the table).	en	Babenko, Anatoly, Shveenkova, Yulia, Potapov, Mikhail (2022): The genus Micranurida Börner, 1901 sensu Deharveng 1982 (Collembola Neanuridae, Pseudachorutinae) in the fauna of the Russian Far East.
