Abstract
More than 1500 proturan specimens from Hainan Island are systematically studied. An annotated list of all species of Protura from Hainan Island is provided and their geographical distribution is discussed. The genus Paracondeellum is reported from Hainan Island for the first time, and Paracondeellum paradisumsp. nov. is described. The type species Paracondeellum dukouense (Tang & Yin, 1988) is redescribed based on syntype, and the lectotype and paralectotype are designated. The characters of the genus Paracondeellum are redefined, and the two known species are compared in detail. The Protura fauna of Hainan Island is mainly composed of species from the Oriental region, with 91% of the species belonging to the families Berberentulidae and Eosentomidae.
Highlights
Protura is a group of tiny soil-dwelling arthropods with more than 800 described species (Bu et al 2012, 2017; Galli et al 2018)
Protentomidae is recorded for the first time and one new species of genus Paracondeellum Yin, Xie & Zhang, 1994 is identified and described
Based on more than 1500 proturans collected in Hainan Island from 1984 to 2017, a checklist is presented and the distribution of Protura on Hainan Island is summarized
Summary
Protura is a group of tiny soil-dwelling arthropods with more than 800 described species (Bu et al 2012, 2017; Galli et al 2018). There are 214 species belonging to 43 genera recorded in China (Bu et al 2012, 2017; Qian et al 2018). The tropical forest landscape on Hainan Island is one of the hotspots for biodiversity in China, with a high floral diversity and over 6000 species of insects recorded (Huang 2002). In 2005, Amphientulus sinensis Xiong, Xie & Yin, 2005 was described and seven new records and three undetermined species were newly added (Xiong 2005; Xiong et al 2005). In 2011 and 2017, we investigated the soil fauna of Hainan Island on several occasions and collected many proturan specimens. Protentomidae is recorded for the first time and one new species of genus Paracondeellum Yin, Xie & Zhang, 1994 is identified and described. Based on more than 1500 proturans collected in Hainan Island from 1984 to 2017, a checklist is presented and the distribution of Protura on Hainan Island is summarized
