the definition of the Haplothipini，and renewed the list of 34 C ao ＆ Feng，2011; Dang ＆ Q iao，2012) ． In the subfamily genera worldwide within the tribe． In C hina，Zhang ( 1984) Phlaeothripinae，although more than 300 genera include no reviewed C hinese Haplothripini species including 7 genera and more than 10 species，there are still four large genera including 24 species． According to the updated classification system more than 100 species． For it is difficult to distinguish so many ( M ound ＆ M inaei，2007)，there are 12 genera in the tribe genera based on only morphological characters，there is not Haplothripini from C hina ( T able 1 ) ． O f these，Haplothrips satisfactory formal classification or key to them in the subfamily species are widespread in C hina，and Plicothrips Bhatti was just until now ． Earlier， Priesner ( 1961 ) suggested that known in T aiwan Island． Phlaeothripinae should be divided into 10 tribes，and listed 34 Table 1． Genera of ChInese HaplothrIpInI． Names of genera Nos． of species Distribution in C hina Fujian， T aiwan， Guangdong， Hainan， Guangxi， Androthrips karny，1911 3 Guizhou，Yunnan Apterygothrips Priesner，1933 2 Inner M ongolia，Ningxia，Sichuan ，T ibet Bagnalliella karny，1920 1 Beijing，Shandong，Shaanxi，Jiangsu，Zhejiang，T aiwan Dolichothrips karny，1912 4 T aiwan，Guangdong，Hainan，Yunnan Dyothrips kud，1974 1 Fujian，T aiwan，Guangdong，Yunnan Haplothrips Amyot ＆ Serville，1843 18 W idespread in C hina Hunan， Fujian， T aiwan， Guangdong， Hainan， Guangxi， Karnyothrips W atson，1923 2 Sichuan，Guizhou，Yunnan Mesothrips Zimmermann，1900 6 Fujian，T aiwan，Hainan，Guangdong，Hong kong，Yunnan Plicothrips Bhatti，1979 1 T aiwan Podothrips Hood，1913 3 Henan，T aiwan，Guangdong，Guizhou Praepodothrips Priesner ＆ Seshadri，1952 2 Guangdong，Hainan，Yunnan Sinuothrips C ollins，2000 1 Inner M ongolia Xylaplothrips Priesner，1928 3 Fujian，T aiwan，Guangdong，Hainan，Yunnan * C orresponding author，E-mail: qiaogx@ ioz． ac． cn T his research was supported by the National Science Funds for Distinguished Young Scientists ( 31025024)，National Science Fund for Fostering T alents in Basic Research ( J1210002)，a grant ( O529YX5105) from the key Laboratory of the Zoological Systematics and Evolution of the C hinese Academy of Sciences，and the M inistry of Science and T echnology of the People's Republic of C hina ( M O ST 2011FY120200) ． Received 28 Dec． 2012，accepted 28 Feb． 2013． 427 428 Acta Zootaxonomica Sinica Vol． 38 No． 2 T he genus Sinuothrips C ollins in Haplothripini was erected in maximum 64，top 19． But in the other genera of Haplothripini， 2000 with the only species S． hasta C ollins． C ollins ( 2000 ) the head shape is almost subparallel-sided，or constricted at base collected the species in thatching reed of Phragmites australis like Mesothrips species ( O kajima，2006) ． unusually，and thought it was invaded into England from O nly for the remarkable projection on the front of head， T urkey by transportation． Now Sinuothrips hasta C ollins is firstly Sinuothrips is similar to Rhinoceps Faure． However，in Sinuothrips， discovered in Ejina Banner of Alashan League，Inner M ongolia， the projection is unique including two parts，which are the short C hina． In this paper，as a new record genus and species，it was and broad projection between the front edge of eyes and basal described and illustrated． For more identifying characters，DNA part of antennal segment Ⅰ，and the ensiform projection from barcoding sequences ( COⅠ) are provided here as well． the base of antennal segment Ⅰ to the apex of segment Ⅳ with round-sided and blunt end， like antenna arising from the 2 MaterIals and Methods projection ( Figs 1，9);
