I–III respectively, VT with 6–8 chaetae (usually 7); non-crossed type chaetae on cephalic posterior area. Including the new species, sixteen species of genus Lobellina are known worldwide. Seven of them have O chaeta on cephalic tubercle Fr, of which, 4 with chaeta O free from the tubercle, and three species, i.e. L. nanjingensis, L.fusa and L. gladius sp. nov. with chaeta O included in tubercle Fr. The new species can be easily differentiated from the other two species of the last group by the following key.Published as part of Hu, Ya-Hui, Jiang, Cheng & Jiang, Ji-Gang, 2019, Two new species of Lobellini from Central-South China (Collembola Neanuridae), pp. 77-89 in Zootaxa 4712 (1) on pages 83-88, DOI: 10.11646/zootaxa.4712.1.5, http://zenodo.org/record/358686

T(T)over-bar deformations with N = (0,2) supersymmetry
No full textWe investigate the behavior of two-dimensional quantum field theories with N = (0,2) supersymmetry under a deformation induced by the "T (T) over bar" composite operator. We show that the deforming operator can be defined by a point-splitting regularization in such a way as to preserve N = (0, 2) supersymmetry. As an example of this construction, we work out the deformation of a free N = (0,2) theory, compare to that induced by the Noether stress-energy tensor and argue that, despite their apparent difference, they are equivalent on shell. Finally, we show that the N = (0,2) supersymmetric deformed action actually possesses N = (2,2) symmetry, half of which is nonlinearly realized

Paratypes, same data as holotype (2 IOZCAS); Jiashi (1160 m), 20-VI-1959, leg Afu Tian (1 IOZCAS); Hejing, 26-VII-1958, leg Changqing Li (1 IOZCAS). Diagnostic description. Length 1.90–2.50 mm (Fig. 97–100). Vestiture on dorsum grayish unicolorous. Rostrum (Fig. 219–222) moderately long, poorly sexually dimorphic, slightly longer in female than in male (Rl/Rw 5.30–5.50 in male, 7.00– 7.50 in female; Rl/Pl 0.88–0.92 in male, 0.93–0.94 in female), thin, in lateral view curved at base, then almost straight to apex. Pronotum (Pw/Pl 1.10–1.17) with slightly rounded sides from base to apex, slightly wider than long. Elytra suboval (Ew/Pw 1.26–1.36; El/Ew 1.50–1.69), with slightly rounded sides in basal half. Femora (Fig. 295–296) unarmed, tibiae (Fig. 333) without sexual characters. Third tarsomere moderately wider than second tarsomere (Fig. 346). Claws (Fig. 358) with small medial teeth as long as 1/3 of claw, separated from claw from base. Male genitalia: body of penis (Fig. 389) in dorsal view moderately large, parallel-sided near to apex, with acutely pointed apex (Fig. 425), in lateral view strongly curved and very subtle, nearly as long as apodeme. Female genitalia: spermatheca see Fig. 453; spiculum ventrale (Fig. 480) with thin arms spaced in basal third but distinctly narrowing to middle, then completely joined to apex. Remarks and comparative notes. This species is closely related to T. tachengicus and T. sulphureus. Tychius zhangi differs by the rostrum of both sexes being longer and that of the female in lateral view of the same width from the antennal insertion to the apex and not distinctly narrowed. The medial teeth of the claw are distinctly smaller and shorter than in the other two species. Finally, the body of the penis in dorsal view is moderately large, parallelsided near to apex, with acutely pointed apex, in lateral view strongly curved and very subtle, nearly as long as an apodeme.

Holotype, male, CHINA: Xinjiang: Tacheng, Alhagi sparsifolia, 24-VI-1984, leg Jiahu Fu (IOZCAS). Paratypes, same data as holotype (15 IOZCAS). Diagnostic description. Length 1.70–2.00 mm (Fig. 85–88). Vestiture on dorsum grayish to brown, either unicolorous or bicoloured. Rostrum (Fig. 207–210) short, moderately stout (Rl/Rw 4.55–4.58 in male, 4.73–5.27 in female; Rl/Pl 1.00– 1.04 in male, 1.06 in female), distinctly curved in basal half. Pronotum subparallel-sided from base to distal third, slightly wider than long (Pw/Pl 1.16–1.19). Elytra (El/Ew 1.44–1.51; Ew/Pw 1.37–1.43) with rectilinear sides in basal half. Femora (Fig. 289–290) unarmed, tibiae (Fig. 330) without sexual characters. Third tarsomere slightly wider than second tarsomere (Fig. 343). Claws (Fig. 355) with medial teeth as long as half of claw, separated from claw from base. Male genitalia: body of penis (Fig. 386) narrow, elongate subparallel-sided until near apex, then gradually narrowing, with subacute tip (Fig. 421), nearly as long as apodeme. Female genitalia: spermatheca see Fig. 450; spiculum ventrale (Fig. 477) with arms almost joined for their whole length. Remarks and comparative notes. This species is closely related to T. sulphureus by its habitus; however, in T. tachengicus the rostrum is shorter, stouter and less tapered in lateral view (especially in the female), the colour of the vestiture is a little variable but never sulphur yellow, third tarsomere slightly wider than second tarsomere, and claws with medial teeth as long as half of claw. Moreover, the aedeagus is distinctly different. Both species are related to T. franzi Caldara, 1986, which is not known from China. However, in T. franzi the rostrum is short, distinctly tapered from base to apex and poorly sexually dimorphic. Etymology. The Latin adjective refers to the type locality, Tacheng, at the borders between China and Kazakhstan. Biology. The specimens of the type series were collected on Alhagi sparsifolia Shap.

Compare of SCIENCE STUDIES Theory System in China and Foreign Countries Based on Scientometrics
No full textDuring the last 10 years, a new framework of SCIENCE STUDIES Theory System has been formed with the progress of science and technology (S&T). Starting with the research tradition and paradigm, we study the main academic fields, the relative disciplines and focuses of SCIENCE STUDIES with the analytical tools and the methods in Scientometrics. The results of study conclude the following:
-in the applied. field, “Science”, “Technology”, “Innovation” and corresponding “S&T Policy and Management” are found in the mainstream;
-in the methodological field, “Webometrics”, “Knowledge Mapping and Visualization Technology”, which are the advanced domains, have developed greatly;
-in the theoretical field, scholars and scientists start to focus on the interaction of Science-Technology-Innovation, the evolution of some disciplines in natural science and the theory of cooperation in S&T.
Basing on the above, the construction of SCIENCE STUDIES Theory System in the new century is discussed
