描述了产于秘鲁东南部的长角石蛾（Leptoceridae：Triplectidinae：Grumichellini）一新属、新种--Osflintia manu。本文重新讨论了Grumichellini莫尔斯（Leptoceridae：Triplectidinae）的发生，并重新考虑了一些形态特征的同源性假设。证实了该族的单系性，并推断其所包含属的系统发育关系为（Triplexa（Gracilipsodes（（Grumichella，Amazonatolica）（Atanatolica，Osflintia，n.）））从成虫和幼虫的特征。新属的特征包括：胫距公式缩小（2，2，2），前翅横脉sc-r1消失，后翅盘状室关闭，后翅叉IV存在，雄性外生殖器背甲IX上有一对长刚毛，X节顶端有一对突起。
Osflintia manu, new genus, new species, of long-horned caddisfly (Leptoceridae: Triplectidinae: Grumichellini) is described and illustrated from southeastern Peru. The phylogeny of Grumichellini Morse (Leptoceridae: Triplectidinae) is revisited and hypotheses of homology of some morphological characters are reconsidered. The monophyly of the tribe is corroborated and the phylogenetic relationships of its included genera are inferred to be (Triplexa (Gracilipsodes ((Grumichella, Amazonatolica) (Atanatolica, Osflintia, n. gen.)))) from adult and larval characters. Diagnostic characters of the new genus include the following: reduced tibial spur formula (2, 2, 2), loss of forewing crossvein sc-r1, hind wing discoidal cell closed, hind wing fork IV present, pair of long setae on tergum IX of the male genitalia, and pair of processes on the apex of segment X.
