            <p>REMARKS</p>
            <p> Whether a number of triadophlebiomorphan species should be included, or not, in this genus, remained a conundrum for decades due to the incompleteness of the available material on one hand, and inadequate data on some of its potential relatives. Preliminarily, in the holotype of  Reisia gelasii , circular elevations with a puncture in their middle occur in the area between RP1 and RP2 [at least in its basal part; noted by Reis (1909) as ‘pores’; see Fig. 1E, F]. This is unique among triadophlebiomorphans but might have been overlooked and/ or may be poorly preserved in other members of this taxon. Indeed, similar structures were observed by Carpenter (1947) in Permian, large-sized meganisopterans. According to this author, they might represent setal bases. The occurrence and distribution of these structures would need a better documentation for their systematic relevance to be properly assessed. Our new data and observations led us to concur withBechly (1997; and see Grauvogel &amp; Laurentiaux 1952) that the genus  Triadotypus Grauvogel &amp; Laurentiaux, 1952 must be regarded a junior synonym of  Reisia Handlirsch, 1912 . Indeed, as far as preserved, the respective holotypes (and only known material) of the type-species of each genus (  Reisia gelasii [Fig. 1] and ‘  Triadotypus ’  guillaumei [Fig. 2]) are nearly identical, including size (width opposite the RP1/RP2 fork, 22.0 mm and about 22.4 mm, respectively), but for: i) the RP1/RP2 fork and the point of origin of the first I- in the RP3+4, both located in a slightly more basal position in  Reisia gelasii ; and ii) a higher density of cross-veins in the median part of the wing in  Reisia gelasii . Such traits are best regarded as of specific relevance. Among characters advocated by Nel et al. (2001) to maintain  Reisia and  Triadotypus as distinct genera, only the branching pattern of MP (or lack thereof) is preserved in both holotypes. Even though the holotype of ‘  Triadotypus ’  guillaumei is comparatively poorly preserved in the corresponding area, the course of the CuA distal-most branch suggests that MP indeed possesses genuine posterior branches, as in  Reisia gelasii . Another notable point is that in ‘  Triadotypus ’  nana , consistently regarded as closely related to ‘  Triadotypus ’  guillaumei by previous authors (including Nel et al. 2001), MP clearly has several posterior branches. </p>
            <p> We further noted unexpected similarities between  Reisia guillaumei n. comb. and ‘  Rabru ’  rubra . Even if the latter is known from a fragmentary, single wing, its wing venation matches, in nearly every aspect, that of  Reisia guillaumei n. comb. , including the organisation of CuP, provided with two main stems and an I+ between them. Both species are also very similar in size (width opposite the RP1/RP2 fork about 21.4 mm in ‘  Rabru ’  rubra ). We therefore propose to assign ‘  Rabru ’  rubra to the genus  Reisia . One notable point regards the number of MP and CuA branches, lower in  Reisia rubra n. comb. than in any other species herein assigned to  Reisia . This trait is considered as of specific relevance. As for  Reisia nana (Laurentiaux-Vieira, Ricour &amp; Laurentiaux, 1952) , known from a very fragmentary, single wing, there are virtually no differences between it and  Reisia guillaumei n. comb. , apart from a distinctly smaller size (judging from the morphology of the latter, wing width is about 14.0 mm opposite the RP1/RP2 fork in  Reisia nana ), which justifies maintaining the species (Bechly 1997). </p>
            <p> The assignment of ‘  Triadotypus ’ sogdianus Pritykina, 1981 to the genus  Reisia , provisionally proposed by Nel et al. (2001), is dubious, as this species has (compared to  Reisia species for which the corresponding traits are documented): i) the first fork of the first I- in the area between RP3+4 and MA area located more basally; ii) a more developed MP; and iii) curved CuP and AA. This species should probably be assigned to a genus on its own. The case of ‘  Reisia ’  rieki Deregnaucourt, Wappler, Anderson &amp; Béthoux, 2017 will be addressed below. </p>
            <p> In summary, available evidence points towards marked similarities between  Reisia gelasii ,  Reisia guillaumei n. comb. ,  Reisia rubra n. comb. and  Reisia nana . Yet, it must be acknowledged that most of these species are known from fragmentary material. Future discoveries might reveal unforeseen differences, making it necessary to reinstate some of the genera herein regarded as junior synonyms of  Reisia . </p>

            <p> Reisia gelasii (Reis, 1909)</p>
            <p>(Fig. 1)</p>

            <p>  EXAMINED MATERIAL. — Holotype and only known specimen SNSB-BSPG 1908 I 49 (right wing in dorsal aspect; ‘  Bayerische Staatssammlung für  Paläontologie und Geologie’, Munich, Germany; Fig. 1). </p>
            <p> TYPE LOCALITY AND STRATIGRAPHY. —  Münnerstadt , Germany; Muschelkalk basin, Schaumkalkbänke Member, Jena Formation; Anisian, Triassic (Paleobiology Database; Nel et al. 2001). </p>
            <p> EMENDED DIAGNOSIS. — Width opposite the RP1/RP2 fork about 22 mm (lower in  Reisia nana ); in the area delimited anteriorly by RP2 and posteriorly by the first I- between RP3+4 and MA, approximately in the median area of the wing (between the origin of the first I- in the RP3+4 and its first fork), cross-venation denser than in surrounding areas (autopomorphic trait); MP with 4 main posterior branches (in addition to its anterior stem; lower in  Reisia rubra n. comb. ). </p>
            <p>REMARKS</p>
            <p> Among triadophlebiomorphans, the comparatively high density of cross-veins in the median area of the wing is unique. We submit that it is relevant to distinguish  Reisia gelasii from other  Reisia species (area poorly known in  Reisia rubra n. comb. , but which has fewer MP and CuA branches; area unknown in  Reisia nana , which is distinctly smaller). </p>
            <p>There is little to add to the original description by Reis (1909) of the available material. Yet, the exceptionally wellpreserved vein corrugation provides interesting clues on how intercalaries can mimic main veins. In the distal part of the RP3+4-MA area four pairs of convex and concave intercalaries (I+ and I-) arise from regularly convex cross-veins, close to RP3+4 (Fig. 1B, C; two of these pairs visible on Fig. 1C). More basally, a very similar pair of intercalary arises from a cross-vein which elevation can be considered neutral. Even more basally, the concavity typical of the I- of the pair applies to the cross-vein in connection with RP3+4. In other words, the I- of a pair of intercalaries adopts a vein-like origin. This case clearly supports the view that the apparent posterior (concave) branch of RP3+4 is more likely an extensively developed I-.</p>
            <p> Another relevant aspect of wing venation homology for which the specimen provides some clues regards the number of MP vs CuA branches, a point that could be referred to as the ‘MP-CuA twilight zone’. In its distal part, MP is undoubtedly provided with three posterior branches (Fig. 1B, D; the most distal and most basal ones have a clear concave origin; only the most basal one of the three is visible on Fig. 1D). More basally, concave structures do not display such clear concave origin from MP. As for CuA, even though its basal stem is not preserved, it can be assumed from data on  Reisia guillaumei n. comb. (Fig. 2) and  Piroutetia liasina (Fig. 3) that it has two branches at least, probably more (in green on Fig. 1A). Then, the nature of structures encircled in white on Fig. 1D is not obvious. A first interpretation, favoured herein, predicts that a CuAprlg (see ‘Material and methods’ section) might begin to form, crossing one posterior branch of MP (which putative base is indicated by ‘0’ on Fig. 1D). This vein would then have a total of five main branches (four posterior branches in addition to the ending of its main stem), and CuA three preserved ones, and most likely four in total, as in  Reisia guillaumei n. comb. A second interpretation predicts that CuA extends further, with a total of five main branches (four preserved and one inferred), and MP four (including its main stem). The case of  Piroutetia liasina (Fig. 3), where no CuAprlg can be assumed, shows that CuA has fewer branches than MP (two vs three). We therefore favour the interpretation that, in  Reisia gelasii , a CuAprlg occurs along a short section and that CuA most likely had four branches (three of which are preserved). </p>

            <p>(Fig. 3)</p>
            <p>  EXAMINED MATERIAL. — Holotype and only known specimen MNHN.F.B09711 (left wing in ventral aspect;  Muséum national  d’Histoire naturelle, Palaeontology collection, Paris, France; Fig. 3). </p>
            <p>REMARKS</p>
            <p> The redescription of the holotype (and only known specimen) of this species by Nel (1989) only needs a minor emendation, regarding the occurrence of a cross-vein more oblique than others in the distal part of the RA-RP1 area. Such a cross-vein commonly occurs in Triadophlebiomorpha (Pritykina 1981). The excellent preservation of veins corrugation in the specimen makes it particularly interesting. It can be assessed that MP is branched distally, posteriorly pectinate, with a total of 4 branches. The first posterior branch of MP as identified by Nel (1989) is herein regarded as an intercalary vein occurring between the two branches of CuA, which is more consistent with: i) the lack of a concave base in connection with MP; ii) the position of this structure relative to the most distal (genuine) MP branches; and iii) the common occurrence of such Icua in Triadophlebiomorpha. The course of Irp 1 -rp 2 (expected to be convex) is not evident if considering veins elevation:our proposal (Fig.3A) supposes that it is alternatively convex and concave (Fig. 3B). A possible explanation is that Irp 1 -rp 2 is fused with a posteriorly pectinate I- that would have occurred between Irp 1 -rp 2 and RP2. Such a structured I- is known in  Cladophlebia parvula Pritykina, 1981 (see original description), in which it seemingly originates from RP2. Moreover, it is separated from Irp 1 -rp 2 by a very narrow area. A fusion of the two structures, as proposed herein for  Piroutetia liasina , is therefore plausible. </p>

            <p> EXAMINED MATERIAL. —  Holotype and only known specimen 7885/7886 (left wing in dorsal and ventral aspect, respectively; also referred to as ’57.32’ or ‘5732’ in the literature; Louis Grauvogel collection at the ‘Staatliches Museum für Naturkunde Stuttgart’, Stuttgart, Germany; Fig. 2).</p>

            <p>REMARKS</p>
            <p> Our investigation revealed a number of discrepancies between previous descriptive accounts and what can be observed in the available material. Most importantly, the part that Nel et al. (2001) regarded as the base of MP (and Grauvogel &amp; Laurentiaux [1952] as the base of CuP) turns out to be the pons, which is very long. Incidentally, it is strongly convex, which is inconsistent with an identification as (part of) MP. The course of the actual base of MP, although poorly preserved, yet is substantiated by a marked concave groove immediately posterior to the pons (black arrow on Fig. 2E, F). Additionally, there is no evidence of a long RP+MA stem, as suggested by Nel et al. (2001). The corresponding area is not preserved in the side preserving the wing in dorsal aspect (Fig. 2): only a very short section of the stem of RA (or R) is preserved, ending opposite the white arrow on Fig. 2E, F. The splitting plane then runs at the level of ScP, which is well exposed, with a short section of MA visible (i.e. RA and RP are embedded in the other side of the specimen). Further on, where preserved, RA (blue arrow on Fig. 1A, B), RP and MA are clearly distinct. Quite unfortunately the corresponding area is totally missing in the side preserving the wing in ventral aspect (7886), probably as a consequence of rock splitting at the time of collection. Given our current knowledge of the wing morphology in triadophlebiomorphans, it is rational to assume that RP and MA run next to each other, but distinct, in  Reisia guillaumei n. comb. (Fig. 2A; and see above). </p>

            <p>REMARKS</p>
            <p> It will be shown below that ‘  Reisia ’  rieki Deregnaucourt, Wappler, Anderson and Béthoux, 2017 is a junior synonym of  Triassologus biseriatus Riek, 1976 . This could imply that  Triassologus is a junior synonym of  Reisia . However, new data derived from additional material of  Triassologus biseriatus (see below) and on  Reisia spp. (see above) allows to convincingly differentiate the two genera, including the width of the area between the anterior wing margin (or ScA) and ScP, and the particular organisation of I- and CuA branches in the CuA-CuP area, among others. </p>
            <p> The more complete data on  Triassologus biseriatus (see below) led us to compare it with the Australian Triassic species ‘ Iveryia ’  aveyri Béthoux &amp; Beattie, 2010 (type species of the genus  Iverya Béthoux &amp; Beattie, 2010 ). Indeed, as far as comparison can be made, the two species do not display major differences other than size-related ones, such has the overall number of vein branches (assuming that the only known specimen of ‘  Iverya ’  aveyri is a forewing, it is about 1.4 times larger than in that of  Triassologus biseriatus ). We therefore propose to newly assign ‘  Iverya ’  aveyri to  Triassologus , further exemplifying similarities between South African and Australian Triassic insect faunas (Tierney et al. 2020; Béthoux &amp; Anderson 2021). </p>
            <p> Bechly (1997) considered that RP2 is branched in  Triassologus biseriatus . However, bearing in mind the propensity of intercalary veins to acquire a main vein habitus points to  Odonata in general and Triadophlebiomorpha in particular, an alternative option, favoured herein, is that the apparent anterior branch of RP2 (large blue arrow on Fig. 4B-D, F) instead is the first I- in the area between Irp 1 -rp 2 and RP2. </p>
