The postcostal cell forms a narrow band, slightly narrower than the radial cell band, and as wide as C1 cell. ScP+RA and RP fork late with ScP+R more than 2.5 times as long as basal cell. MP forks in C3 at the same level of Pcu and A1 fusion and CuA remains single up to the apical level of the clavus, then forks in an open C5. CuP is almost straight, connected by transverse veins to CuA. Pcu and A1 are connected in the last quarter of the clavus.</p><p>Etymology</p><p>Arbitrary combination referring to the forewing CuA vein (cubito costa) single and the generic name Issus .</p><p>Note</p><p>Previously placed in Issinae sec. Wang et al. (2016), Hysteropterini were recently regarded deserving a subfamily rank (Zhao et al. 2019). They differ from Issinae Issini by their late forking of CuA after the end of the clavus while CuA forks well before in Issini genera. By its venation schema, Cubicostissus gen. nov. tegmen approaches species of Tshurtshurnella Kusnezov, 1927, but it appears more elongated: 2.6 times as long as wide (× 2 or less in Tshurtshurnella) and with a late fusion of Pcu and A 1 in the last quarter of the clavus (earlier in Tshurtshurnella). From Hysteropterum Amyot &amp; Audinet-Serville, 1843, it differs by the elongated tegmen, the absence of identified apical cells, the presence of some transverse veins between CuA and CuP and, at mid-length, the costal area almost as wide as C1 and the open radial cell. Its simpler venation also easily separates this new taxon from all the other issid fossils currently known.</p></div>	https://treatment.plazi.org/id/A8588792EA34FFADFD853BEBFE9926A5	Public Domain	No known copyright restrictions apply.

Basal cell (bc) short, 0.29 mm long. No hypocostal plate. Anterior margin slightly and regularly convex, maximum convexity at level of MP fork. Posterior margin slightly concave at the end of the clavus. Common stem ScP+R more than twice as long as basal cell (0.67 mm long). Postcostal cell forming a narrow band, slightly narrower than radial cell, itself narrower than basal cell. ScP+R forking late: ScP+R 2.7 times as long as basal cell. Radial cell open, as wide as C1 cell before mid-length of tegmen, with ScP+RA and RP running parallel. Vein MP 1.33 mm long, forking late in cell C3 at same level of fusion of Pcu and A1; MP1+ 2 in straight line with vein MP; MP3+4 diverging posteriorly. CuA almost straight, single up to apical level of clavus, separated from MP and MP3+4 by a wide area (open median cell) almost as wide as area width between MP+MP3+4 and costal margin. C5 cell open. CuA connected with parallel CuP before mid-length of tegmen by four transverse veins. Just before reaching clavus, apically forked with CuA1 starts running parallel to the tegmen margin and CuA2 joining tegmen margin. Pcu and A1 connecting late in the last quarter of a long closed clavus. A1 closely parallel to posterior margin. Traces of brownish coloration and small micro-granulations are visible in cubito-anal and subcostal areas (Fig. 1).</p></div>	https://treatment.plazi.org/id/A8588792EA35FFABFE5D383FFC89209B	Public Domain	No known copyright restrictions apply.
