Forewing: opposite the end of ScP, area anterior to RA large (accounting for about a quarter of wing width).	en	Béthoux, Olivier, Anderson, John M.

039DFA6CFFDEFFDD6D65FD87CD59FEF8.taxon	discussion	Discussion. Genera herein assigned to the Polycytellidae display two states that have been generally regarded as relevant to the systematics of Glosselytrodea, namely: (1) occurrence of a single mid-vein (or, ‘ two mid-veins fused into a single mid-vein, as opposed to ‘ occurrence of two, closely adjoined but distinct, mid-veins’); and (2) anterior and posterior ambient veins joining each other at their apices (as opposed to ‘ anterior and posterior ambient veins reaching the anterior and posterior margins, respectively’). Martynova (1952; and see Martynova, 1962, 1991) regarded these traits as diagnostic of the Polycytellidae, to which she also assigned Mesojurina Martynova, 1943 (including Mesojurina sogjutensis Martynova, 1943, Jurassic, Kyrgyzstan; and see below). However, Rasnitsyn & Aristov in Aristov et al. (2013) considered that this combination of traits may have been acquired convergently within two distinct families, namely the oligoneurous Jurinidae Zalessky, 1929 and the polyneurous Glosselytridae Martynov, 1938. Besides the number of veins, which can be partly related to size, this proposal rests on scenarios of forewing elytrization, achieved either by membrane strengthening or veins strengthening. However, these aspects remain difficult to appreciate based on data currently available on Glosselytrodea. Of further interest, it is common that the area between the anterior wing margin and ScP is enlarged in Glosselytrodea. Consequently, the anterior wing margin has a marked inflexion opposite the end of ScP. However, in genera herein assigned to the Polycytellidae, the area anterior to RA (i. e., between ScP and RA and then between the anterior wing margin and RA) is also enlarged (opposite the end of ScP, nearly as large as the area between RA and MP + CuA ant), with the consequence that the anterior wing margin regains a more continuous course. This trait can be described as follows: (3) ‘ opposite the end of ScP, area anterior to RA large’ (as opposed to ‘ RA close to ScP and, distal to the end of this vein, close to the anterior wing margin’). It is present in Polycytella (Fig. 1), Argentinoglosselytrina and the new material described below (Figs 2 – 4). This trait is most likely derived, as it is unique among Glosselytrodea and, to our knowledge, winged insects as a whole. A seemingly similar condition occurs in Blattodea, in which the area between the anterior wing margin and the stem of R is often very wide (Rehn, 1951). However, this R stem emits successive anterior branches, the anterior-most ones belonging to RA. As a consequence, the actual area between ScP and RA corresponds to the area between ScP and the first anterior branch of R, and is narrow. The conditions in Polycytellidae and Blattodea are therefore not homologous. Considering that Mesojurina displays the plesiomorphic condition of the character (viz., the state ‘ RA close to ScP and, distal to the end of this vein, close to the anterior wing margin’), we therefore exclude this genus from the Polycytellidae, which, as a consequence, is strictly Gondwanan. Whether the corresponding taxon shall better be considered a subfamily to be nested within Jurinidae or Glosselytridae remains to be elucidated.	en	Béthoux, Olivier, Anderson, John M.

039DFA6CFFDDFFDB6D65FEB2C9E1FB09.taxon	discussion	Discussion. Despite the limited available data on Argentinoglosselytrina, it can be assessed that species herein assigned to the genus Polycytella share a termination of CuP located distal to the wing mid-length (it is located opposite to it in Argentinoglosselytrina; condition unknown in Moltenojurina), a putatively derived condition. Additionally, in both species the wing apex is slightly deflected posteriorly (a trait partly inferred for Polycytella triassica), while it is not that pronounced in Argentinoglosselytrina and not the case in Moltenojurina. The marginal band is very broad in Moltenojurina, unlike in species herein assigned to Polycytella (and in Argentinoglosselytrina). Finally, species herein assigned to Polycytella (and Argentinoglosselytrina) share similar size range (forewing length 7.2 – 9.4 mm), in contrast to Moltenojurina, which type and only known species has forewings about half smaller.	en	Béthoux, Olivier, Anderson, John M.

039DFA6CFFDBFFDA6EC7FA81C983FBE0.taxon	description	Redescription. A right forewing, with most of the margins and apex missing; preserved length 7.2 mm (about 8.2 mm if complete), width 2.2 mm; area between anterior wing margin and ScP broad, with at least 4 rows of small cells; in this area, occurrence of a conspicuous ambient vein parallel to the anterior wing margin; just distal to the end of ScP, area between anterior wing margin and RA broad (0.6 mm wide opposite the end of ScP); MP + CuA ant rectilinear in its basal half, then slightly deflected posteriorly; area between RA and MP + CuA ant broadening from wing base to the ca. 3 / 5 of wing length, then tapering, with 4 veins at its broadest; area between MP + CuA ant and CuA post broadening from the wing base to the ca. 3 / 5 of wing length, then tapering, with 4 veins at its broadest; CuA post simple, very slightly bent opposite the end of CuP; occurrence of an intercalary vein between CuA post and CuP, originating about 1.6 mm before the end of the latter; claval furrow concave, rectilinear, closely bordered by two convex vein-like elements, the anterior one herein regarded as CuP, the posterior one as AA 1 or a derivative of cross-venation (thereafter ‘ AA 1 ’); distally, claval furrow and both of these elements barely distinguishable from a single vein, ending 4.7 mm distal to wing base; two well-defined veins (AA?) converging towards the end of CuP, with 4 rows of cells between AA 1 and the first of these veins; the second of these veins located in a depression.	en	Béthoux, Olivier, Anderson, John M.

039DFA6CFFDBFFDA6EC7FA81C983FBE0.taxon	discussion	Discussion. The polarity of the specimen GSQ 81 a is not evident at first glance. The fact that cross-veins are preserved as depressions points towards a negative imprint, while the claval furrow preserved as a depression points towards a positive imprint. One possibility, then, is that the specimen is a negative imprint of a ventral side. This interpretation is corroborated by portions of RA appearing as convex tubular elements (in particular opposite the end of ScP), representing a positive imprint of the dorsal side of a then right forewing. In turn, if this is a right forewing, negatively imprinted cross-veins can only be accounted for by a negative imprint of a ventral side. Whether an intercalary vein occurs between CuA post and CuP (as represented on Fig. 1), or whether this vein is the genuine CuA post instead, is not evident to assess, essentially because the posterior part of the marginal band is poorly preserved. Considering that, on one hand, CuA post is a conspicuously convex vein in Polycytella rasnitsyni, and that, on the other, the vein of concern lies in a depression, while the vein anterior to it (‘ CuA post ’ on Fig. 1) is elevated, we considered it unlikely that it could be CuA post. The development of an intercalary vein in this area is not unlikely, given that similar structures occur in the area between the anterior wing margin and ScP, and in the area anterior to RA.	en	Béthoux, Olivier, Anderson, John M.

039DFA6CFFDAFFD96EC7FBDAC941FD1B.taxon	discussion	Discussion. The new material is very similar to Polycytella triassica, particularly in the relatively distal location of the end of CuP (unknown in Mo. parva, see below). Differences mainly regard aspect ratio, the shape of cells in the 3 rd quarter of wing length, and the occurrence, or lack thereof, of an intercalary vein between CuA post and CuP (basal to the end of the latter). Considering that it is more informative to emphasize similarities rather than differences, we propose to assign the new material to the same genus as Polycytella triassica. The occurrence of intercalary veins running very close to the posterior wing margin, basal to the end of CuP, is probably part of a forewing interlocking mechanism. Indeed, the occurrence of one or several vein-like structures (main and / or intercalary vein (s )) bordering the actual posterior wing margin, basal to the end of CuP or along its entire length, is common in insects with elytrized forewings, such as Dermaptera and some Dictyoptera (Tillyard, 1931; Nel et al., 2014; Béthoux et al., 2016; Luo et al., in press). Most elaborated cases involve a three-dimensional tongue-and-groove structure, as in Coleoptera (Breed & Ball, 1908; and see Nachtigall, 1974), which appears as composed of multiple, parallel vein-like elements when viewed dorsally. The bordering of the claval furrow by two vein-like elements (one of the two being CuP) is a configuration that can be observed in elytrized forewings of grasshoppers (OB, pers. observ.), among others. In Polycytella rasnitsyni the interlocking mechanism may have involved the posterior margin of the clavus on one hand, and the area of the claval furrow on the other. Indeed, when folded along the claval furrow, the posterior margin of the clavus of the overlapping forewing overlaps the claval furrow of the overlapped forewing. To best appreciate this the reader is encouraged to cut wings illustrated on Fig. 3 along their margin, use the tip of a pointed blade (or a needle) and a ruler to gently imprint a line of weakness along the claval furrow, and assemble the wing pair in resting position, with the claval furrow forming a 90 ° angle.	en	Béthoux, Olivier, Anderson, John M.

039DFA6CFFD9FFD86EC7FB4DCA79FE10.taxon	discussion	Discussion. Because of its incompleteness and the symmetry characterizing Glosselytrodea forewings, it was not straightforward to orientate the specimen. We rested on the fact that the clavus is commonly delimited by a series of rectilinear, close and parallel veins in Glosselytrodea. Provided that it is not the case in the preserved area which could have been interpreted as the clavus, we interpreted it as the area anterior to RA instead. Additionally, veinlike elements preserved in the corresponding area display a zigzagging course, known to be the case for similar elements preserved in the area anterior to RA in Polycytella and Argentinoglosselytrina. In a similar line of reasoning, the lack of a rectilinear vein interpretable as ScP suggests that the specimen was broken along this vein, a damage not uncommon in fossil wings of Glosselytrodea (see Hong, 2007; Rasnitsyn & Aristov in Aristov et al., 2013). A tentative reconstruction was elaborated accordingly (Fig. 4). It implies that the area anterior to RA is very broad, ensuring the assignment of the specimen to the Polycytellidae as diagnosed above. The new material differs from any known Polycytellidae by its small size. As a matter of fact, to our knowledge, it is the smallest Glosselytrodea to date. More decisively, the marginal band is broader than in other Glosselytrodea: opposite the 3 rd quarter of wing length, the marginal band (anterior and posterior sections) accounts for about a quarter of wing width in Polycytella spp., while it accounts for more than a third in the new material. These traits justify the erection of a new genus and, incidentally, of a new species. General similarity between the new material and Mesojurina sogjutensis Martynova, 1943 is regarded as due to the small size characterizing both species. Notably, Mesojurina sogjutensis has an area anterior to RA comparatively narrow, this precluding its assignment to the Polycytellidae as diagnosed above.	en	Béthoux, Olivier, Anderson, John M.
