No full textGenus Pentachares Li & Guo gen. nov. urn:lsid:zoobank.org:act: 080C87A4-FFE2-459E-AC36-6A414126B7F0 Type species Pentachares sinensis Li & Guo gen. et sp. nov. Etymology Five-segmented palp is the main diagnosis feature of this new genus. “Pent-” means five, just represents the five segments of palp in this new genus. Diagnosis Characters of Rhyncholimnocharinae; palp five-segmented, P-V attached to the middle surface, rather than the distal end of P-IV; dorsalia absent; without swimming setae on legs. Habitat Same as subfamily. Distribution Oriental realm. Remarks The new genus presents the diagnostic features of both two subfamilies in Limnocharidae: a long tube of protrusible integument proves that it belongs to Rhyncholimnocharinae, meanwhile the palp with five segments indicates it is from Limnocharinae. The phylogenetic value of the palp-fused as a character has been questioned (Cook 1974; Gerecke et al. 2020). Therefore, we arrange the new genus in Rhyncholimnocharinae, according to the feature of a tubular extension of integument.Published as part of Jin, Dao-Chao & Guo, Jian-Jun, 2022, Contributions to the knowledge of Eylaoidea (Acari: Hydrachnidiae) from China, pp. 53-70 in European Journal of Taxonomy 787 (1) on page 61, DOI: 10.5852/ejt.2021.787.1613, http://zenodo.org/record/581795

Remarks Pentachares sinensis Li & Guo gen. et sp. nov. with five-segmented palp is clearly distinguished from other species of the subfamily Rhyncholimnocharinae, but similar to Laterolimnochares huangshanensis Jin, 1999 and Limnochares spinosa Smit & Pesic, 2014. Pentachares sinensis Li & Guo gen. et sp. nov. differs from La. huangshanensis in the following aspects: 1) with a protrusible tube of soft integument in P. sinensis Li & Guo gen. et sp. nov., while without in La. huangshanensis; 2) body color amber in P. sinensis Li & Guo gen. et sp. nov., while pink in La. huangshanensis; 3) O 1 rod-shaped in P. sinensis Li & Guo gen. et sp. nov., while pectinate in La. huangshanensis; 4) terminal heavy seta of P-V smooth in P. sinensis Li & Guo gen. et sp. nov., while feathered in La. huangshanensis; and 5) the setae on coxae short in P. sinensis Li & Guo gen. et sp. nov., but long in La. huangshanensis. Pentachares sinensis Li & Guo gen. et sp. nov. differs from Li. spinosa: 1) with a protrusible tube of soft integument in P. sinensis Li & Guo gen. et sp. nov., while without in Li. spinosa; 2) O 1 and O 2 not smooth in P. sinensis Li & Guo gen. et sp. nov., but smooth in Li. spinosa; 3) terminal heavy seta of P-IV smooth in P. sinensis Li & Guo gen. et sp. nov., but feathered in Li. spinosa; and 4) the number of acetabula 50–60 in P. sinensis Li & Guo gen. et sp. nov., while only 40–50 in Li. spinosa.

Reincarnations of Labor Reportage: Nonfiction by Chinese Migrant Worker Authors
No full textLiterary reportage and workers’ literature have historically been imbricated in
a productive relationship. In this chapter, I approach nonfiction (feixugou 非
虛構) as a contemporary genre (that roughly came about in the 2000s), high-
lighting its thematic and stylistic connections to industrial-themed reportage
literature and especially its function as an instrument for workers to construct
self-narratives, thus participating in reportage art’s active (and often critical)
intervention in the social space where it is produced (see Chen’s, Mirra’s,
and Moran’s chapters in this volume). As case studies, I present nonfiction
accounts written by two workers, Meng Yu 夢雨 and Yuan Wei 苑偉. Both are
members of the Picun Literature Group (Picun wenxue xiaozu 皮村文學小
組), a collective devoted to literary training and creative writing for rural-to-
urban migrant laborers
