Insecta Mundi 2023 2023-12-01 2023 16 1 33 Zhang & Cong & Shen & Song & Grishin, 2023 Zhang & Cong & Shen & Song & Grishin 2023 [326,427,1570,1599] 23 22 subGenus subgen. nov. Grishin    Typespecies.  Pterygospidea extensaMabille, 1891.  Definition.Sister to the rest of the genus  GorgopasGodman and Salvin, 1894( typespecies  Achlyodes viridicepsButler & H. Druce, 1872, which is currently regarded as a junior subjective synonym of  Pellicia chlorocephalaHerrich-Schäffer, 1870) and sufficiently distinct from it ( Fig. 5), resembling in appearance some species of  Polyctor Evans, 1953( typespecies  Pirgus[sic!] polyctorPrittwitz, 1868). Keys to E. 18.4 in Evans (1953)and distinguished from its relatives by nearly square hindwing due to a blunt tooth at the vein CuA 1and hyaline spots in forewing cells between veins M 1to 1A+2A. In DNA, a combination of the following nuclear genomic base pairs is diagnostic: aly770.25.10:A48C, aly451.25.1:G1816A, aly3686.9.6:G137C, aly 1656.12.3:G757C, aly5196.9.2:C832T.   Etymology.The name is a masculine noun (to agree in gender with the names of species in this subgenus) in the nominative singular, given for the square-shaped hindwing: in Latin, quadratumis square, and alisis wing.  Species included.Only the typespecies.  Parent taxon.Genus  GorgopasGodman and Salvin, 1894.
