            <p>Type material.</p>
            <p> Holotype: ♂ on slide (slide number HNHM-collpr-911), Hungary,  Bács-Kiskun county,  Fülöpháza , 106 m a.s.l., 46°52'16"N, 19°25'14"E, D-vac sample, 12 Jun. 2020, leg. D. Winkler and G.  Ónodi . Paratypes: ♀ on slide (slide number HNHM-collpr-912) and six ♂♂ on slide (slide numbers HNHM-collpr-913 to HNHM-collpr-914; WD-coll-141 to WD-coll-144, respectively); same data as holotype. The holotype and three paratypes are deposited at HNHM. Four paratypes are preserved at SOE in the first  author’s collection. </p>
            <p>Diagnosis.</p>

            <p>Ecology and distribution.</p>
            <p> The habitat of the type locality is extremely xerophilic. It belongs to the Pannonic sand steppes, where the vegetation is a partly opened grass dominated by  Festuca vaginata and  Stipa borysthenica (Fig. 6). </p>
            <p>Etymology.</p>
            <p> The name of the new species refers to the habitat, Pannonic open sand steppes, where  E. arenaria is one of the most dominant epigeic  Collembola species. </p>
            <p>Remarks.</p>
            <p> Based on the colour pattern,  E. arenaria sp. nov. is very close to  E. violaceolineata Stach, 1963, with the difference that, in the case of the latter, neither the original description (Stach 1963) nor other descriptions (Jordana 2012) mention the presence of a dark ventral side, which is a key character of the new species. Stach (1963) only notes that, similarly to  E. schoetti Stach, 1922, the dark-pigmented body side often appears also in individuals of  E. violaceolineata .  Entomobrya arenaria sp. nov. differs from  E. violaceolineata by the morphology of the labral papillae (rounded with one strong-armed spine-like projection in the new species while truncate and bearing three short setulae in  E. violaceolineata ). There is a further difference regarding the apical bulb of the fourth antennal segment, trilobed in the new species, while simple (sensu Stach 1963) or bilobed (sensu Jordana 2012) in  E. violaceolineata . The shape of unguiculus is also different, as its external edge is serrate in the new species while smooth in  E. violaceolineata . The Abd IV/III ratio of  E. arenaria sp. nov. is above 4, while Abd IV of  E. violaceolineata is relatively short, resulting in a smaller (~3) Abd IV/III ratio. Based on specimens collected in Spain, Jordana (2012) was the first to provide the complete macrochaetotaxy for  E. violaceolineata , compared to which marked differences in the number of macrochaetae can be observed in most areas, including head H1, H4, and H5; Th II T2; Abd II A2; Abd III A3 and A5; Abd IV A6, A7, and A8, respectively (Table 1). Regarding habitat characteristics,  E. arenaria sp. nov. inhabits xerophilic open grasslands, while  E. violaceolineata has been found under dead leaves and litter in parks, pine and riparian forest litter, and belts of meadows along river banks (Stach 1963; Jordana 2012;  Buşmachiu et al. 2017). </p>

            <p> Upon further investigation, ten species share the same or very similar macrochaetotaxy of Abd II-III (Table 1), namely  E. armeniensis Jordana, Potapov &amp; Baquero, 2011;  E. cheni Baquero, Arbea &amp; Jordana, 2010;  E. handschini Stach, 1922;  E. hirsutothorax Jordana &amp; Baquero, 2021 (in Baquero et al. 2021);  E. kuznetsovae Jordana, Potapov &amp; Baquero, 2011;  E. murreensis Yosii &amp; Ashraf, 1965;  E. nigriventris ;  E. pazaristei Denis, 1933;  E. strigata Stach, 1963;  E. taigicola Jordana, Potapov &amp; Baquero, 2011; respectively. While the colour pattern of the new species is quite different from the abovementioned species, there are differences also in chaetotaxy and other characters (Table 1).  Entomobrya armeniensis is characterised by a slightly different formula for the head and has an additional Mac (S4p) absent in the new species, fewer Mac on the T1 area of Th II, A8-A9 area of Abd IV.  Entomobrya cheni bears significantly more Mac on Abd IV areas A7, A8, and A10, respectively, and fewer chaetae on the manubrial plate compared with  E. arenaria sp. nov. The dorsal macrochaetotaxy scheme of  E. handschini is very close to that of the new species, with the only difference involving the area H1 on the head with fewer Mac (3 or 4); in addition, the smaller number of chaetae on the manubrial plate can be mentioned when compared to the new species. In the case of  E. kuznetsovae , the simple apical bulb (trilobed in the new species) and the presence of macrochaetae in the A6 area in Abd IV (without Mac in the new species) can be highlighted as differential characters.  Entomobrya murreensis differs from  E. arenaria sp. nov., most notably by the macrochaetae formula of Th II and by the presence of macrochaetae in the A6 area in Abd IV. The dorsal macrochaetotaxy scheme of  E. nigriventris and  E. strigata is very close to that of the new species. In  E. strigata , differences include fewer Mac in the area H1 on the head, T1 area of Th II, and A7-A9 areas of Abd IV.  Entomobrya nigriventris has only one Mac in the area H5 of the head and, similarly to  E. strigata , has a significantly smaller number of chaetae on the manubrial plate. The cave-dwelling species  E. pazaristei differs from the new species by the different Mac formula for the head, the higher number of Mac in the area T1 in Th II, and the presence of macrochaetae in the A6 area of Abd IV.  Entomobrya taigicola mainly differs from the new species by the higher number of Mac (3) in the area H2 on the head, the fewer number (1) of Mac in the area A8 of Abd IV, and fewer chaetae on the manubrial plate. </p>

            <p>Ecology.</p>
            <p>The specimens were collected in a secondary hay meadow with woody patches.</p>
            <p>Remarks.</p>
            <p> Baquero et al. (2008) presented a comprehensive redescription of  E. handschini , providing a large set of characters (including macrochaetotaxy) from specimens from five different localities (Austria, Crete, Greece, Iran, and Slovakia). Variations in colour pattern are presented in several works, however, neither the original description (Stach 1922) nor the subsequent redescriptions (Stach 1963; Baquero et al. 2008; Jordana 2012) mention the possible occurrence of a dark-coloured ventral side, which is presented in this paper for the first time. Further differences compared to previous descriptions include slight variations in the macrochaetotaxy of some areas. There is one more Mac (a total of four) in the area H1 (head). However, this phenomenon is also observed in other  Entomobrya species, especially in larger individuals, where the antennal series can include more macrochaetae (  Furgoł 2017). T2 area (Th II) can have one more Mac, while A2 area (Abd II) can bear two more additional Mac than previously reported (Baquero et al. 2008; Jordana 2012). On Abd IV, the presence of unpaired macrochaetae has not previously been reported, while in the studied specimens, we occasionally detected unpaired chaetae in areas A7, A8, and A9, respectively. The number of Mac in the A9 area can reach up to five, including a Mac of uncertain homology always present in the B row. The same Mac was also indicated by Baquero et al. (2008) as Ae5pp shifted outwards. </p>
            <p> The abovementioned differences can be considered as slight variations. Taking them into account, the species  E. handschini can be characterised by the following simplified formula: 3(4)-1-0-3-2/4-5(6)/2-5(7)/0-2-2/0-10(0)3(5)-10(0)4-10(0)3(5)-2. </p>

            <p>Ecology and distribution.</p>
            <p> The type locality near the settlement Simontornya is situated on the loess ridges of the southern Transdanubian region of Hungary. According to historical maps, the area was pasture and mowed meadow centuries ago. Nowadays, the effects of intensive grazing can be observed on the grass vegetation, which consists of common species like  Bothriochloa ischaemum ,  Galium verum ,  Salvia pratensis (Fig. 9). Based on the habitat and climatic characteristics, the species can be considered xerophilic. Notably, we also detected some of the co-existent species Ferenc Pillich collected together with  E. nigriventris and sent to Jan Stach for determination. These include species Stach described together with  E. nigriventris in the same paper (Stach 1929):  Orchesella hungarica Stach, 1929 and  Pseudosira pillichi Stach, 1929, recently synonymised with  Seira pallidipes Reuter, 1895 (Winkler and  Dányi 2017), as well as other  Entomobrya species such as  E. handschini Stach, 1922 and  E. quinquelineata Börner , 1901. </p>
            <p> Until now,  E. nigriventris has been known only from its type locality in Hungary (Simontornya). Although the species has been frequently reported from open sand steppes in Central Hungary (Hornung 1986; Loksa 1987; Traser 2002; Traser and  Horváth-Szováti 2006;  Flórián et al. 2019), these observations covered another species described in this article as  E. arenaria sp. nov.. Traser et al. (2006) reported the species from West Hungary in a moss habitat, but re-examining their collected material proved this observation erroneous. In Spain, Arbea and Jordana (1985) detected a species (  E. cf. nigriventris ) that shows similarities based on the colour pattern. On the other hand, considering its habitat (beech forest, with moss cover in the more open parts), it is likely to represent another species. </p>
            <p>Remarks.</p>
            <p> Entomobrya nigriventris was described based on a single specimen (Stach 1929), which entails the problem that the natural variability of the diagnostic characters cannot be determined. In addition to the new and essential information on the chaetotaxy and its variations, the examination of the newly collected specimens also allowed us to describe the size range and the colour pattern from the juvenile to the adult stage. Some of the already known characters (colour pattern, morphology of labral papillae, lateral process) are in accordance with the original description (Stach 1929) and later redescriptions (Stach 1963; Jordana 2012) based on the holotype. Morphology of Ant IV apical bulb can be bi- or trilobed (we found both variations in the newly collected specimens); in the holotype, it is trilobed (Stach 1963). This moderate intraspecific variation has already been reported in other  Entomobrya species (Katz et al. 2015). However, there is a difference regarding the morphology of the claw III that must be mentioned. In the case of the holotype, the number of inner teeth on the claw is three, with only one (medial) unpaired tooth, while the apical unpaired tooth is reported to be absent (Stach 1963; Jordana 2012). In the freshly collected specimens from the type locality, an additional minute apical tooth was always present. This variability, although not common, may occur in  Entomobrya (Jordana and Baquero 2006) and other derived genera of  Entomobryomorpha , such as  Lepidocyrtus (e.g., Mateos 2008; Winkler 2017),  Pseudosinella (Winkler and Mateos 2018), and  Heteromurus (Yoosefi Lafooraki and Shayanmehr 2014). It is also worth noting that Stach (1963) reported  E. quinquelineata as a species with three inner teeth, while the original description (  Börner 1901) and its redescriptions (Baquero and Jordana 2008; Jordana 2012) do not mention the absence of the apical unpaired tooth. </p>
            <p> Apart from the dark ventral side and the presence of the longitudinal thin stripe running along the dorsal centreline, the colour pattern of  E. nigriventris is very close to  E. strigata Stach, 1963, originally described from Poland (Stach 1963). It can be, however, distinguished by the morphology of labral papillae (with spine-like projection in  E. nigriventris and with plain surface in  E. strigata sensu Stach (1963)). The holotype of  E. strigata is reported to be lost; therefore, to describe the dorsal macrochaetotaxy and additional characters missing from the original description, specimens collected in Armenia were used by Jordana (2012). This allowed us to observe further differences between the two species in the chaetotaxy. The head Mac formula differs slightly in  E. strigata , with more Mac in the H2 and H5 areas. In contrast, there are fewer Mac in the area T1 of Th II and in the area A8 of Abd IV, and there are fewer chaetae also in the manubrial plate (Table 1). </p>

            <p>Ecology.</p>
            <p>The specimens were collected in xerophilous dolomite-steppe meadow plant associations.</p>
            <p>Remarks.</p>
            <p> The specimens collected in Hungary differ in their colour pattern from the original form described by  Börner (1901), which Stach (1963) later named f.  Entomobrya principalis , and in which the longitudinal central and dorsolateral stripes run uninterrupted to the posterior part of Abd IV. The similarity in the colour pattern can be discovered mostly with individuals from Switzerland, Holland, or Lithuania, presented in the species redescription (Baquero and Jordana 2008), in which the longitudinal stripes are interrupted on Abd IV. Nevertheless, the occurrence of a dark ventral side has not been described in this species until now, although it is not rare in some populations. </p>
            <p> In their comprehensive redescription of  E. quinquelineata based on European materials, Baquero and Jordana (2008) provided the essential dorsal macrochaetae distribution and information on its variability. The dorsal macrochaetotaxy of the Hungarian specimens is fairly consistent with the previous redescriptions (Baquero and Jordana 2008; Jordana 2012). Differences include the presence of Mac S1 in the H4 area of the head. The number of macrochaetae in this area is usually two. However, in a specimen from Switzerland, the presence of a third macrochaeta was hinted at but marked as questionable because of the poor condition of the slide examined (Baquero and Jordana 2008). </p>
            <p> Although the dorsal colour pattern suggests that we found a population of  E. quinquelineata , considering the abovementioned difference in head chaetotaxy, we identify it as  E. cf. quinquelineata . </p>

            <p>Ecology.</p>
            <p>The species was found in an urban park (grass habitat) in considerable abundance.</p>
            <p>Remarks.</p>
            <p> Originally described from the Spanish mainland (Stach 1930),  E. unostrigata has since been detected mainly from southern European countries, such as Italy (Simon 1965), France (Renaud et al. 2004), and Bulgaria (Tsonev and Kazandzhieva 1991), as well as introduced to North America and Australia (Christiansen 1956; Greenslade 1995). In Hungary, this is the first record of the species. The fact that it was found in the capital, where it proved to be extremely abundant, but not anywhere else, despite the extensive  Collembola collections that have taken place in the country in the past decades, raises the idea that the species was also introduced in Hungary. </p>
            <p> The specimens collected show great variability in terms of pattern and colour form. In the original (Stach 1930) and later descriptions (Stach 1963), the author distinguished three forms based on the colour pattern. Apart from the typical principal form, a slightly different pattern was described as var.  Entomobrya unostrigata dorsosignata , as well as a pale-coloured form (ab.  Entomobrya astrigata ) without any pattern but a small dot between the antennae. Further variations in colour pattern and pigmentation have been documented by, e.g., Wray (1953), Christiansen (1958),  Simón (1976), Christiansen and Bellinger (1980), Greenslade (1995), and more recently by Katz et al. (2015), Baquero and Jordana (2018), and Jordana and Greenslade (2020). Dark lateral pigmentation on the edges of certain tergites has already been noted (e.g., Stach 1963;  Simón 1976; Katz et al. 2015), and darker pigmented specimens have also been presented in some papers (Greenslade 1995). Nevertheless, specimens with dark ventral sides or completely dark specimens with hardly visible patterns (as in Fig. 14C, D) we found in the sampled Hungarian population have not been described yet. </p>
            <p>Large individuals are not uncommon in the studied Hungarian material; the maximum length (without antennae and furca) almost reaches 4 mm, while, according to the data published so far, the species is smaller: specimens up to 2 mm from the Spanish mainland (Stach 1963), up to 2.5 mm from the United States (Christiansen and Bellinger 1980), up to 2.62 mm from the Canary Islands (Baquero and Jordana 2018), and up to 2.35 from Australia (Jordana and Greenslade 2020), respectively. Similarly to European and Australian specimens, the eyes G and H are smaller compared to C and F, while they are similar in size in the case of specimens from the USA (Katz et al. 2015).</p>
            <p> Slight variations in the macrochaetotaxy of some areas can also be detected compared to previous descriptions (Katz et al. 2015; Baquero and Jordana 2018; Jordana and Greenslade 2020). Larger specimens often have four Mac in the H1 area of the head. In some specimens, there is one more additional Mac also in the H2 area. Similarly to the specimens from North America, we found four or five Mac in area A2 of Abd II, while individuals from Australia and other European regions bear three or four macrochaetae in this area. On Abd IV, the unpaired macrochaetae A03-A05 are present in the Hungarian individuals (the absence of these macrochaetae has only been documented in North American individuals (Katz et al. 2015 )). The number and homology of macrochaetae in the areas A6-A10 roughly correspond to those documented in previous redescriptions (Katz et al. 2015; Baquero and Jordana 2018; Jordana and Greenslade 2020). Considering all these variations, the species  E. unostrigata can be characterised by the following simplified formula: 3(4)-1(2)-0-3-2(3)/1-4/2-4(3-5)/1-0-1/4(2-5)-10(0)4(5)-10(0)1(2)-10(0)2(1-3)-2(3). </p>
