Specimen examined. 1♂, CHINA: Guangdong Province, Xinyi, alt. 1,000 m, 8 August 2003, coll. D. Zhang, genitalia slide no. ZAH04109. Distribution. China (Guangdong). Remarks. The male forewing has a circular pocket at base of 1A+2A vein in H. triangulum. This species resembles H. axiotima (Meyrick) in the male genitalia, but differs by forewing with a white triangular patch above ocelloid patch, tegumen blunt dorsolaterally and uncus triangular. In H. axiotima forewing bears a wide creamwhite streak not touching costal triangular patch apically, tegumen bears a pair of large ear-like lobes and uncus is mound-like.Published as part of Zhang, Aihuan, 2021, Study on the Genus Hendecaneura Walsingham from China (Lepidoptera: Tortricidae), pp. 359-366 in Zootaxa 4966 (3) on page 365, DOI: 10.11646/zootaxa.4966.3.7, http://zenodo.org/record/473679
Polystichum tiandengense (subg. Haplopolystichum; Dryopieridaceae), a New Cave Fern from Guangxi, China
No full textA new fern species, Polystichum tiandengense H. He & Li Bing Zhang (Dryopteridaceae), is described and illustrated from a limestone cave in the Guangxi Zhuangzu Autonomous Region, South China. Polystichum tiandengense is most similar to P. cavernicola. Li Bing Zhang & H. lie in having oblong to square pinnae with undulate margins, but the new species is distinguished by its pinnae mostly adjacent to each other or imbricating, and mostly sterile (vs. distant from each other and mostly fertile in P. cavernicola). Polystichum tiandengense is considered to be Critically Endangered (CR), based on RICN Red List criteria
Siamiassus constanti Dai, Dietrich & Zhang, 2015, sp. nov.
No full textSiamiassus constanti sp. nov. (Figs 5 C, D, 20 A–D, 23 A) Male 8.4 mm long, 3.9 mm wide across humeral angles. Color dull olive green; forewing densely marked with small black spots in basal 2 / 3 and along veins near apex; front and middle femur black in distal half, front tibia dark brown (Fig. 5 C, D). Structural features as described for genus (Fig. 20 A–D). Type material. Holotype ♂ THAILAND: Loei, Na-Haeo (edge pond) 17.v. 2003, J. Constant & K. Smets, light trap [RISB]. Notes. This species is named in honor of Dr. Jerome Constant, Auchenorrhyncha expert at the Royal Belgian Institute of Natural Sciences, Brussels, collector of the holotype and host to CHD during a recent visit to Brussels. Siniassus nom. nov. (replacement for Sinojassus Dai, Zhang, Zhang & Dietrich 2010, nec Sinojassus Zhang 1985) Notes. The genus was described by Dai et al. (2010) and given the name Sinojassus, but this name is a junior homonym of an older fossil genus, Sinojassus Zhang (1985) and, therefore, must be given a new replacement name. Siniassus resembles Trocnadella in overall body form and the absence of a separately articulated connective in the male genitalia, but may be distinguished by the presence of numerous dark spots on the dorsum and the elongate style apodeme.

Finite-Time H∞ Filtering for T-S Fuzzy Discrete-Time Systems with Time-Varying Delay and Norm-Bounded Uncertainties
No full textIn this paper, we investigate the filtering problem of discretetime Takagi–Sugeno (T–S) fuzzy uncertain systems subject to time-varying delays. A reduced-order filter is designed. With the augmentation technique, a filtering error system with delayed states is obtained. In order to deal with time delays in system states, the filtering error system is first transformed into two interconnected subsystems. By using a two-term approximation for the time-varying delay, sufficient delay-dependent conditions of finite-time boundedness andH∞ performance of the filtering error system are derived with the Lyapunov function. Based on these conditions, the filter design methods are proposed and the filter gain matrices can be obtained by calculating a set of linear matrix inequalities. A numerical example is used to illustrate the effectiveness of the proposed approaches.Zhuo Zhang, Zexu Zhang, Hui Zhang, Peng Shi, and Hamid Reza Karim
