The genus Allonychiurus Yoshii, 1995 is briefly introduced and a new Chinese species, Allonychiurus megasomus sp. nov., from Jiangsu Province, is described. The new species is diagnosed as having 32/133/33343 dorsal pso, 11/000/ 01110 ventral pso, 0/000/10000 ventral parapseudocelli (psx), 2/012/22222 dorsal sensilla, PAO consisting of 18–22 compound vesicles, Abd. IV with median setae a 0 and p 0 , Abd. V with m 0 , tibiotarsus with 11 setae in the distal whorl, unguiculus without basal lamella and ventral tube with 8+8 setae. It is easily separated from other known species in the genus by the combination of above characters. The status of the species in the genus is discussed.
Green development is an effective way to achieve economic growth and social development in a harmonious, sustainable, and efficient manner. Although the Yangtze River Economic Belt (YREB) plays an important strategic role in China, our understanding of its spatiotemporal characteristics, as well as the multiple factors affecting its green development level (GDL), remains limited. This study used the entropy weight method (EWM) to analyze the temporal evolution and spatial differentiation characteristics of the GDL in the YREB from 2011 to 2019. Further, fuzzy-set qualitative comparative analysis (fsQCA) was used to analyze the influence path of GDL. The results showed that the GDL of the YREB increased from 2015 to 2019, but the overall level was still not high, with high GDL mainly concentrated in the lower reaches. The GDL model changed from being environmentally driven and government supported in 2011 to being environmentally and economically driven since 2014. The core conditions for high GDL changed from economic development level (EDL) to scientific technological innovation level (STIL) and environmental regulation (ER). The path for improving GDL is as follows: In regions with high EDL, effective ER, moderate openness level (OL), and high STIL are the basis, supplemented by a reasonable urbanization scale (US). In areas with low EDL, reasonable industrial structure (IS) and STIL are the core conditions for development; further, EDL should be improved and effective ER and OL implemented. Alternatively, without considering changes to EDL, improvement can be achieved through reasonable OL and US or effective ER. This study provides a new method for exploring the path of GDL and a reference for governments to effectively adjust green development policies.
The genus Psyllaphorura is reported from China for the first time. A new species, Psyllaphorura jiangsuensis sp. n. as the eighth species of the genus, is described from Nanjing, Southeast China. It is most similar to the Russian species Psyllaphorura martynovae (Stebaeva, 1985) in many respects. However, it can be distinguished from the latter by number of vesicles in the postantennal organ, number of setae on ventral tube, length ratio of unguiculus to unguis, absence of unguiculus basal lamella and maximum body length. A key to all of the species of Psyllaphorura is provided.
A new onychiurid species, Thalassaphorura qixiaensis sp. nov., is reported from Jiangsu Province of East China. Morphologically, it is very similar to the widely-spread and definitely parthenogenetic species Th. encarpata (Denis, 1931). The new species is gamogenetic and differs from the latter in labial palp and proximal setae. A key to the Chinese species of the genus is given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
