AbstractThe genusPhanoperla (=DyaperlaBanks, 1939) (Plecoptera: Perlidae: Perlini) is revised and generic diagnoses are provided for adults and larvae. Diagnostic and constitutive characters of the tribe Neoperlini are discussed, andChinoperlaZwick, 1980, is shown to be the closest relative ofPhanoperla.Many past misidentifications ofPhanoperlaspecies have been corrected by the use of characters recently recognized as important, namely the structure of the internal genitalia of male and female specimens and particularly the complex pattern of spines on the male penial sac made visible by eversion of this structure, and details of sculpturing of the egg chorion.The following species ofPhanoperlaare recognized:amorphasp.n.;anomala(Banks, 1939);bakeri(Banks, 1924);ceylonicaKawai, 1975;comutasp.n.;flaveola(Klapálek, 1921), comb.n. (=clarissa(Banks, 1913),syn.n.), (=Neoperla hageniBanks, 1920, syn.n.), (=N.consimilisBanks, 1924,syn.n.); guttatasp.n.;himalayanaZwick, 1977 (=siwalikaHarper, 1977);limosa(Hagen, 1858);maculatasp.n.;maindroni(Navas, 1926), comb.n.;malayanasp.n.;minutissima(Enderlein, 1909);nana sp.n.; nervosaBanks, 1939;nuwaraKawai, 1975;omegasp.n.;pallipennis(Banks, 1938);parvasp.n.;pumilio(Klapálek, 1921), comb.n.;peniculusKawai, 1969a;schmidisp.n.;sertispinaJewett, 1975;srilankasp.n.;sumatraesp.n.;testacea(Hagen, 1858);weddasp.n.P.claggi(Banks, 1938) is anomen nudum.All species are (re‐)described and figured; all primary types have been examined. A key to species is provided. Most species can be assigned to one of seven species groups which are defined.Phanoperlais endemic to the Oriental Region. Species groups are generally widespread, but individual species are in most cases known only from restricted ar
