CHINA: Shaanxi Province, Yangling, holotype female, 5 female, 1 male paratypes, from grasses, 21.vi. 1987 (Feng Ji-Nian) NWAFU; 8 females, 1 male from clover, 22.v. 2010 (M. Mirab-balou) ZJUH; Shandong Province, Qinzhou, 2 females, 3 males from clover, 26.v. 2010 (Lu Hong, Wei, Shu-Jun, M. Mirabbalou) ZJUH; Beijing, 2 females from alfalfa, 26.v. 2010 (Lu, H., M. Mirab-balou) ZJUH. Holotype female of Sussericothrips melilotus with 1 female and 1 male paratypes, IOZ. Distribution. China (Shaanxi, Shandong, Beijing, Gansu, Hebei, Henan, Ningxia, Inner Mongolia). Remarks. Han described S. melilotus from Beijing and Gansu, whereas Chou & Feng described H. houji from Yangling. H. houji was compared originally with H. boerhaaviae (Seshadri & Ananthakrishnan), but is here transferred to Sericothrips because of the following character states: presence of microtrichia completely across the abdominal terga, sterna and metanotum (in both micropterous and macropterous morphs); shape of the metasternum; tergal posterior margins with complete microtrichial comb; abdominal terga II–VII with median setae placed similarly and of similar size. S. melilotus shares these character states, and as no further differences could be found after studying Han’s original specimens, this species is here considered a synonym. During sampling in 2009– 2010, we found S. houji in high populations, especially micropterae, on clover and alfalfa fields.Published as part of Mirab-Balou, Majid, Hu, Qing-Ling, Feng, Ji-Nian & Chen, Xue-Xin, 2011, A new species of Sericothripinae from China (Thysanoptera: Thripidae), with two new synonyms and one new record, pp. 55-61 in Zootaxa 3009 on page 56, DOI: 10.5281/zenodo.27857

    Fiorinia dinghuensis Wei & Feng sp. n. (Figs 9–16) Material examined. Holotype: adult female, China: Guangdong Province, Dinghu Mountain, 4 -vi- 1963, Coc 63255, coll. Chou IO (NWAFU). Paratypes: data same as holotype, 4 adult females (NWAFU). Description, n= 5. Mounted adult female. Appearance in life not recorded. Body 754–1041 μm long (holotype 620 μm long); 481–592 μm wide (holotype 509 μm wide). Body outline oval to fusiform. Derm membranous except for pygidium. Cephalothorax. Antennae present close together on a sclerotized area on anterior margin of body; each with a long seta; without an interantennal process. Anterior spiracles each with 5 trilocular pores; pores absent from posterior spiracles. Pygidial lobes. With 2 pairs of lobes: L 1 deeply sunk into pygidium, strongly zygotic, each lobe rather pointed and with 4 notches on inner margin; L 2 bilobed, inner lobules larger than outer lobules, rounded on apex, with 1 notch on each margin; outer lobules rounded on apex, with 1 obvious notch on outer margin. Setae. With 1 pair of setae present between L 1; 1 pair between L 1 and L 2, and a pair on margins of abdominal segments IV, V and VI. Gland spines with 6 pairs of short spines, with 2 pairs present on abdominal III and 3 pairs on abdominal segments IV plus 1 pair between Gland tubercles: 28–32 pairs present marginally on cephalothorax plus abdominal segment I. Macroducts. Marginal macroducts 2 -barred, with 1 pair between L 1 and L 2, 1 pair on abdominal segment VI, 2 pairs on each of abdominal segments IV and V but none between L 1. Submargial and submedial macroducts absent. Ventral microducts few and scattered.

Perivulvar pores in 5 groups, 3–5 in median group, 10–14 in each anterolateral group and 16–20 in each posterolateral group. Remarks. The new species can easily be distinguished from other Fiorinia species by the presence of a sclerotized area on the anterior margin of the head. Fiorinia dinghuensis is similar to F. fioriniae Targioni-Tozzetti, 1867, and F. proboscidaria Green, 1900, in having 2 pairs of pygidial lobes, but can be distinguished by (character states for F. fioriniae in brackets): 1) the presence of 28–32 gland tubercles on the margins of cephalothorax plus abdominal segment I (absent), and 2) absence of gland spines between L 1 and L 2 (present). F. dinghensis differs from F. proboscidaria by (character states for F. fioriniae in brackets): 1) absence of an inter-antennal process between antennae (with a prominent inter-antennal process), and 2) absence of gland spines on abdominal segments V, VI and VII (present). Host. Acronychia pedunculata (Linn.) (Rutaceae). Etymology. The specific epithet refers to Dinghu Mountain, Guangdong Province, China, the type locality. Distribution. China (Guangdong).Published as part of Wei, Jiufeng, Zhang, Bin & Feng, Jinian, 2013, Two new species of Fiorinia Targioni-Tozzetti (Hemiptera: Coccoidea: Diaspididae) from China, pp. 92-100 in Zootaxa 3641 (1) on page 97, DOI: 10.11646/zootaxa.3641.1.10, http://zenodo.org/record/22329

    A Multi-Language Comparison of Influences on Author Verification using Character N-Grams

    No full text
    We create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
