| The subtribe Acrobasiina belongs to the tribe Phycitini of the subfamily Phycitinae in the familyPyralidae. Many species of this subtribe are serious pests and have great economic importance in agricultureand forestry. As the largest group of Phycitinae, Acrobasiina has the largest number of genera and species.Nevertheless, the taxonomic position of some closely allied genera and the status of some closely relatedspecies within Acrobasiina remain in chaos and problematic due to lacking definite characters to define them.China is vast in territory rich in biodiversity, yet the fauna study is far from sufficient. Thus, it is necessaryto revise Acrobasiina in China so as to provide basic and theoretical data for our understanding of thespecies diversity and for the control of important economic pests.This dissertation focuses on the taxonomic revision of the tribe Acrobasiina in China, following thesystem proposed by Roesler (1973). Eighty-six species are involved, including fifty-three species newlyadded to the Chinese fauna. The number of Acrobasiina in China has increased to219species and52generain total.Thirteen genera are newly recorded for China: Ancylodes Ragonot,1887, Dentitegumia Amsel,1961,Ephestiopsis Ragonot,1893, Gunungodes Roesler et Küppers,1981(published), Mesciniadia Hampson,1901, Mesciniodes Hampson,1901, Metallostichodes Roesler,1967, Myelopsis Heinrich,1956, PararotrudaRoesler,1965, Penetiana Hampson,1930, Pristocerella Kieffer,1909, Prorophora Ragonot,1887(published) and Rasputinka Roesler,1989.Thirty-four species are described as new (including two published species): Ancylodes termispinellosasp. nov., Ancylosis (Heterographis) biculcita sp. nov., A.(H.) canalicurta sp. nov., A.(H.) hamisaccula sp.nov., A.(H.) marginipapillata sp. nov., A.(H.) vasistrigulosa sp. nov., A.(Staudingeria) marginalba sp. nov.,A.(S.) pseudosuboblitella sp. nov., Anonaepestis albicosta sp. nov., A. dorsinitida sp. nov., A. termispinatasp. nov., Assara bimacula sp. nov., A. hemiannula sp. nov., A. longitranstilla sp. nov., Christophiaparagranulella sp. nov., C. valvispinifera sp. nov., Dentitegumia hamiclaspera sp. nov., Ephestiopsissimilishiva sp. nov., Euzopherodes furciprocessa sp. nov., E. longiculcita sp. nov., E. longignathosa sp. nov.,E. taenitumefacta sp. nov., Gunungodes zhengi Liu et Li,2011, Homoeosoma (Homoeosoma) nullisignum sp.nov., Lambaesia flexicosta sp. nov., Myelopsis nigilimbata sp. nov., Paramaxillaria angustivalva sp. nov.,Penetiana termirubera sp. nov., Pristocerella longisterna sp. nov., Prorophora (Reisserempista) binacanthaLiu et Li,2012, Pseudocadra acericosta sp. nov., P. flavida sp. nov., P. ligigracilis sp. nov., and Rasputinkalongifasciaria sp. nov.Nineteen species are reported to occur in China for the frist time: Ancylodes staminella (Christoph,1877), Ancylosis (Ancylosis) sareptella (Herrich-Sch ffer,1860), A.(Staudingeria) reginella (Roesler,1970),Assara balanophorae Sasaki et Tanaka,2004, Bazaria gilvella (Ragonot,1887), Cathyalia pallicostellaRoesler et Küppers,1981, Christophia baliella (Ragonot,1888), Dentitegumia classica Roesler,1989,Ephestiopsis vishnu Roesler et Küppers,1981, Gymnancyla (Spermatophthora) hornigii (Lederer,1852),Mesciniadia infractalis (Walker,1864), Mesciniodes micans (Hampson,1896), Metallostichodeshemicautella (Hampson,1899), M. nigrocyanella (Constant,1865), Myelopsis rufimaculella Yamanaka, 1993, Pararotruda nesiotica (Rebel,1911), Penetiana proleucia Hampson,1930, Prorophora (Prorophora)albidogilvella Roesler,1970(published), and P.(Reisserempista) mongolica Roesler,1970(published).The application of the characters of the male eighth abdominal segment and culcita in taxonomy isstudied for the first time, based on which a key to the species of Ancylosis Zeller,1839is provided. Theresult shows that the male eighth abdominal segment and culcita can be used to identify species and are oftaxonomic value in species identification.The taxonomic value of the female signum is discussed. The number, location, shape, the way of itsarrangement as well as the micro structures are summarized.Sixty species are described in detail based on available specimens, and twenty-three species are addedaccording to literature records. Detailed citations, synonyms and the geographical distribution of eachspecies are given. Keys are provided to the known genera of Acrobasiina in China, as well as to all thespecies of each genus involved in this study. Photographs of adults and illustrations of the male and femalegenitalia, as well as the maps to show the geographical distribution of all the species are included.All the specimens studied, including the types, are deposited in the Insect Collection, College of LifeScience, Nankai University, Tianjin, China.The research is supported by the National Natural Science Foundation of China (No.31093430&No.J0930005). |
