No full textSynotis nyalamensis M. Tang, C. Ren, Y.S. Chen & Q.E. Yang, sp. nov., Figs. 1, 2A–C. TYPE:— CHINA. Xizang, Nyalam county, Kangshan bridge to Zhangmu town, 28°02′29.52″N, 85°45′15.97″E, ca. 3200 m a.s.l., gravelly places on mountain slope, 26 August 2013, M. Tang & C. Ren 485 (holotype IBSC, isotypes KUN, PE). Fig. 1. Synotis kunthiana auct. non (Wallich ex Candolle 1838: 169) Jeffrey & Chen (1984: 288): Tang & Yang (2013). Diagnosis:— Synotis nyalamensis is closely similar to S. kunthiana in having abaxially white-tomentose leaves and cylindric-campanulate capitula, but differs by having higher stature (45–60 vs. 20–40 cm), singular (vs. several) stems, caudate-acuminate (vs. acuminate) leaf tips, prominent (vs. obscure) nerves on abaxial side of leaves, more phyllaries (10–13, rarely 8 or 9 vs. 6–8), and more disk florets (15–24 vs. 7–12). Description:—Perennial rhizomatous subshrubs. Rhizomes thick, woody. Stems solitary, erect, 45–60 cm tall, sparsely arachnoid-tomentose, proximally leafless at flowering time. Median stem leaves ovate-lanceolate, green, papery, 6–8 cm long, 3–5 cm broad, caudate-acuminate, remotely and minutely mucronulate-denticulate, adaxially sparsely pubescent, abaxially grey-whitish arachnoid-tomentose, pinnately veined, lateral veins 8–10; petiole 0.8–1.5 cm long; upper leaves becoming gradually smaller, sessile, oblong-linear. Capitula radiate, 3–8, loosely arranged in terminal and upper axillary corymbs on inflorescence branches; peduncles (1.0–)2.0– 4.5 cm long, slender, pubescent, bearing 1–3 filiform bracteoles. Involucres cylindric-campanulate, 8–10 mm long, 4–6 mm broad, with 8–10 subulate bracteoles at base, bracts of calyculus 5 to 8, filiform, green or purple, 6–8 mm long; phyllaries usually 10–13, rarely 8 or 9, linear-lanceolate, 1–2 mm broad, green, herbaceous, sparsely pubescent, margin narrowly scarious, apically acute, pubescent. Ray florets (6–)8, yellow; corolla tube 3–4 mm long; lamina oblong, 4–5 mm long, 1.5–2 mm broad, shallowly 2- or 3-denticulate, 3 or 4 veined, apex acute. Disk florets 15–24; corolla yellow, 7–10 mm long, with 3–4 mm long tube and infundibuliform limb; lobes ovate-triangular, 6–7 mm long, apically acute. Anthers 3–3.5 mm long; anther tails ca. 1.5 times the length of anther collars; appendages ovate-oblong; anther collars slightly dilated at base. Style arms ca. 1 mm long, fringed with short papillae, the apical tuft not differentiated. Achenes cylindric, 2–3 mm long, glabrous. Pappus white, 6–7 mm long. Phenology:—Flowering from August to September; fruiting from October to December. Etymology:—The specific epithet of our new species, “ nyalamensis ”, is derived from the type locality, i.e. Nyalam county in southern Xizang, China. Distribution and habitat:— Synotis nyalamensis is currently known only from its type locality, i.e. Nyalam county in southern Xizang, China (Fig. 5). It grows in gravelly places on mountain slope at an altitude of ca. 3200 m above sea level. Its putative closest ally, Syn. kunthiana, is distributed only in northwestern India, Nepal, and Pakistan, not in China (Fig. 5). Conservation status:— Synotis nyalamensis is a locally endemic species. During our field work we tried our best to search for it around the type locality but discovered only a small population with ca. 15 mature individuals. We have also been unable to trace any herbarium specimen of this species collected prior to us. According to IUCN Red List categories and criteria (IUCN Standards and Petitions Subcommittee 2019), Syn. nyalamensis should be categorized as a Critically Endangered (CR) species. Notes:—As pointed out by Jeffery & Chen (1984), a notable feature of the genus Synotis is the occurrence of closely similar, usually vicariant but sometimes partially sympatric sets of similar species, which on experimental study may prove better distinguished at subspecific rank. They gave eight examples in the Chinese flora. It seems that Syn. kunthiana and Syn. nyalamensis are an example in the Himalayan flora. Morphologically these two species, although different in some characters, are indeed closely similar to each other (Table 1). According to Jeffery & Chen (1984), Chen (1999) and Li et al. (2018), Synotis is divisible into two well-marked sections, sect. Synotis and sect. Karelinioidei (Fedtschenko & Fedtschenko ex Schischkin 1961: 751) Ren et al. in Li et al. (2018: 9). The former is divisible into five not very clearly differentiated series, with S. kunthiana belonging to Syn. ser. Fulvipapposae Jeffrey & Chen (1984: 332). Considering the remarkable morphological resemblance between Syn. nyalamensis and Syn. kunthiana, we propose to place Syn. nyalamensis also within this series.Published as part of Tang, Ming, Ren, Chen, Chen, You-Sheng & Yang, Qin-Er, 2022, Synotis nyalamensis (Asteraceae, Senecioneae), a new species from southern Xizang (Tibet), China, pp. 278-284 in Phytotaxa 554 (3) on pages 280-283, DOI: 10.11646/phytotaxa.554.3.6, http://zenodo.org/record/683152

Material examined. 1♀, Guizhou prov., Fan Jingshan, Huixiangping, 11.VII.1993, Xu Zai-Fu, No. 936615 (ZJUH). Distribution. China (Guizhou, Fujian). Notes. According to the photos taken by M. Sharkey and D. Yu, the holotype of E. wuyiensis Chen et Yang differs from the original description by having the palpi pale yellowish (not dark brown as described) and the length of the first metasomal tergite is 1.3 × its apical width (not 2.3 × as described).Published as part of Tang, Pu, Achterberg, Cornelis Van & Chen, Xue-Xin, 2018, Review of the genus Earinus Wesmael (Hymenoptera, Braconidae, Agathidinae) from China, pp. 345-358 in Zootaxa 4504 (3) on page 357, DOI: 10.11646/zootaxa.4504.3.2, http://zenodo.org/record/260643

No full textMirachelonus subgen. nov. Type species: Chelonus (Mirachelonus) miraventris sp. nov. Diagnosis. Antennomeres 16 in female and 25 in male; flagellum gradually shortens from base to apex; 3 rd –7 th segments comparatively slender, 8 th –11 th segments distinctly widened; head striate-rugose and shiny; mesosoma coarsely reticulate-rugose; scutellum distinctly protruding above level of mesoscutum, with same sculpture as mesosoma; propodeum with a transverse carina and four distinct tooth-like tubercles; third tergite of metasomal carapace almost straightly narrowed, coarsely longitudinal rugulose, connected by transverse elements, smooth apically; apex of carapace truncate and narrow in dorsal view, in lateral view apex of carapace deeply incurved, about one fourth of total length of carapace in lateral view; apex of carapace with a rather small round aperture (Fig. 4J). Etymology. Mirabilis is Latin for wonderful, strange and it is combined with the generic name Chelonus, because of the very special shape of the third metasomal segment of the type species.Published as part of Zhou, Jin-Jin, Achterberg, Kees Van, Tang, Pu & Chen, Xue-Xin, 2022, A new subgenus of Chelonus Panzer, 1806 (Braconidae: Cheloninae) from China, pp. 288-294 in Zootaxa 5115 (2) on page 290, DOI: 10.11646/zootaxa.5115.2.8, http://zenodo.org/record/635248
Space charge behavior in multi-layer oil-paper insulation under different DC voltages and temperatures
No full textOil-paper as a reliable insulation system is widely used in power transformers and cables. The dielectric properties of oil-paper insulation play an important role in the reliable operation of power equipment. However, the formation and dynamics of space charge can affect the performance of insulation material. In this paper, space charge in oil-paper insulation system has been investigated using the pulsed electroacoustic (PEA) technique. A series of measurements were carried out when the insulation system was subjected to different applied voltages at different temperatures. Charge behavior in the insulation system has been analyzed and the influence of temperature on charge dynamics was discussed. The test results show that homocharge injection takes place under all the test conditions, the applied dc voltage mainly effect the amount of space charge, while the temperature has greater influence on the distribution and mobility of space charge inside oil-paper sample
