| The present dissertation comprehensively deals with the morphology, taxonomy,phylogeny and geographic distribution of Thripidae from China. The research history at homeand abroad and the current situation, the general morphology, study material and method aresummarized in detail. Futhermore, based on the extensive collections and references,especially the examination of the types,61genera and173species of Thripidae from Chinaare described and revised in detail. Meanwhile, based on the morphological and distributiondata, the phylogeny and biogeography of the family were also analyzed and discussed. Theprincipal achievements of the present dissertation are listed as follows:1) In the present dissertation,173species in61genera of Thripidae from China aredescribed in detail, eleven new species, two new synonyms, one new combination, threenewly recorded genus and eight newly recorded species included (of which one new species,two new synonyms, two newly recorded genus and five newly recorded species have beenpublished). Meanwhile, the keys to subfamilies, genera, and species of Chinese Thripidae arealso provided, and the illustrations of the morphological characters are given for most species.The new taxa, new records to Chinese fauna, new synonyms and new combiniation arelisted as follows:New species: Chilothrips hangzhouensisi sp. nov., Chirothrips bicolor sp. nov.,Chirothrips cauditubulus sp. nov., Ctenothrips qinlingensis sp. nov., Hydatothripshainanensis sp. nov., Megalurothrips longus sp. nov., Odontothrips hani Hu, Mirab-balou,Chen&Feng,2012, Stenchaetothrips banhongensis sp. nov., Stenchaetothrips cauditubulussp. nov., Thrips bicolor sp. nov. and Thrips peculiaris sp. nov..New synonyms: Odontothrips qinlingensis Feng&Zhao,1994[=Odontothrips loti(Haliday,1852)] and Odontothrips yinggeensis Feng&Zhang,2000[=Odontothrips loti(Haliday,1852)].New combination: Taeniothrips grisbrunneus (Feng, Chou&Li),1995comb. nov..Newly recorded genus: Apterothrips Bagnall,1908, Limothrips Haliday,1836andRhaphidothrips Uzel,1895rec. nov..Newly recorded species: Apterothrips apteris (Daniel,1904), Apterothrips secticornis(Trybom,1896), Ctenothrips niger Kud,1977rec. nov., Ctenothrips smilax Bhatti,1976,Limothrips cerealium (Haliday,1836) rec. nov., Limothrips consimilis Priesner,1926and Limothrips denticornis (Haliday,1836), Rhaphidothrips longistylosus Uzel,1895rec. nov..The type specimen of the new species are deposited separately in the Northwest A&FUniversity (NWAFU).2) The analysis of distribution data of Chinese Thripidae shows that the OrientalRegion holds the richest genera and species diversity of Thripidae, and the Palaearctic Regionwith relatively fewer taxa. The Oriental Region holds86percent of the genera of the twozoogeographical regions, which suggests that most Chinese Thripidae are tropical andsubtropical type. Most Chinese Thripidae species distributed in North China, Central Chinaand South China. It probably because there is no obvious isolation or barrier, e.g. highmoutains and deserts, between the Palaearctic Region and Oriental Region in the eastern ofChina. The species in the two regions can interpenetrate to each other, which makes them tobe the areas with the richest species diversity.3) The phylogeny of the59genera of Chinese Thripidae is reconstructed by usingPaup4.0b10and Treeview (Win32).97morphological characters were selected and the generaAeolothrips and Ophthalmothrips were used as outgroups. The results of phylogenic analysisshow that:1) Thripidae is a monophyly, and Aeolothrips is much closer to ingroup thanOphthalmothrips. Ophthalmothrips is comparatively primitive;2) Dendrothrips is a sistergroup of Pseudodendrothrips;3) Panchaetothripinae is a monophyly, Tryphactothripini andMonilothripini are monophylies, too. But Panchaetothripini is not a monophyly;4)Dendrothripinae is closer to Panchaetothripinae, and it is also a sister group ofPanchaetothripinae;5) The taxonomic status of Sericothripinae still needs further study. |
