Song et al. 1999: 377, figs 221O-P. Draconarius ornatus: Wang 2003: 541, figs 46A-C, 96A. Diagnosis: Similar to D. terebratus (Peng & Wang 1997) by the absence of epigynal teeth, presence of posteriorly situated epigynal hoods, anteriorly extending copulatory ducts, and long spermathecal heads. The female can be distinguished by the slightly elongated atrium, and the male by the broad, distinctly bifurcate conductor and the broad embolus (Figs 316-318). Description: See Wang et al.

The specific name is an adjective from the Latin word cucullata (hood-shaped), and refers to the large hood-shaped conductor of the male palp. Diagnosis. The females of Hamataliwa cucullata sp. nov. and H. torsiva sp. nov. can be separated from all other congeneric species by the covering of the copulatory opening, which is covered with a raised sclerite. The female of this new species H. cucullata can be easily distinguished from H. torsiva sp. nov. by (compare Figs 8, 10, 14 with Figs 19, 21, 23) the larger epigynal depression, the presence of a small hood on the epigynum (absent in H. torsiva sp. nov.) and the absence of a posteriorly sclerotized rim on the epigynum (present in H. torsiva sp. nov.). The male of this new species can be separated from all other congeneric species (e.g. H. foveata Tang & Li, 2012, H. pilulifera Tang & Li, 2012) by the long digitiform VTA and the large, hood-shaped conductor (see Figs 4–6, 12–13).

Haphsa stellata Lee, 2009b: 335; Lee, 2016: 596. Distribution. China (Guangxi), India, Vietnam. Remarks. This species was formerly attributed to Changa as the type species by Lee (2016), and the same author synonymized H. stellata Lee, 2009 with Changa sita (Distant, 1881) (Lee, 2016). In the present paper, we remove it to Haphsa based on morphological characterization and phylogenetic analysis (Fig. 4). Lee (2016) also transferred H. jsguillotsi (Boulard, 2005) to Changa, but we confirm it is a member of Haphsa (see below). Accordingly, Changa Lee, 2016 syn. n. is synonymized with Haphsa.Published as part of Wang, Siyue, Peng, Xiaodong & Wei, Cong, 2021, A review of the cicada genus Haphsa Distant, 1905 with the description of one new species from China (Hemiptera: Cicadidae) and a phylogenetic analysis of Haphsa and its allies, pp. 523-538 in Zootaxa 4991 (3) on page 530, DOI: 10.11646/zootaxa.4991.3.5, http://zenodo.org/record/504258
Non-fragile H infinity control for switched stochastic delay systems with application to water quality process
Full text linkArticle first published online: 14 JAN 2013

Both data missing and time delays are taken into account in the links from sensors to observers and from controllers to actuators. Because data missing satisfies the Bernoulli distribution, such problem is transformed into an H ∞ control problem for stochastic switched delay systems. Average dwell time approach is used to obtain sufficient conditions on the solvability of such problems. A numerical example and a real example for water quality control are provided to illustrate the effectiveness and potential applications of the proposed techniques.Dong Wang, Peng Shi, Wei Wang and Hamid R.

Both the male of <i>P. arcuata</i> and the female of <i>P. levii</i> were collected from Huping Mountain National Nature Reserve and their collection localities are close to each other. Moreover, they share a similar habitus, and are consistent with <i>P. pygmaea</i> in palpal and epigynal structures, respectively (e.g., the male has a sub-oval carapace, three transverse white bands medially on the dorsum of the abdomen, a medially located retromarginal cheliceral tooth, and similarly shaped copulatory ducts). Based on that, it is safe to consider <i>P. arcuata</i> and <i>P. levii</i> as the same species.
