Br. （Apocynaceae） and Aculus paederius Wang, Gu ＆ Tan, sp. nov. infesting Paederia scandens （Lour.） Merr. （Rubiaceae）. Tegolophus artocarpi Keifer, 1977 is newly recorded from China. E. casearius Wang, Yang ＆ Tan, sp. nov. distorts severely new foliage of its host plant. Three species, P. alstonia Wang, Gu ＆ Tan, sp. nov., A. paederius Wang, Gu ＆ Tan, sp. nov. and T. artocarpi, cause rust on the undersurfaces of host plants, while D. litsea Wang, Tan ＆ Yang, sp. nov. is a vagrant on the undersurface of host plant leaves, without visible symptom.展开更多

Diagnosis of the new genus Tegosecans gen. nov. is that body spindle- shaped, scapular setae ahead of rear shield margin; opisthosoma of smooth dorsal and microtuberculate ventral annuli, dorsal annuli with central longitudinal ridge ending before lateral median ridges; second dorsal annulus broader, covering the next 2 annuli, 3–4 dorsal annuli with lateral lobes. The 10 new species are Trisetacus fortunei sp. nov., Glyptacus kweilinensus sp. nov., Neoacaphyllisa phaeosticta sp. nov., Oxycenus tomentosae sp. nov., Phyllocoptacus fortuneir sp. nov., Tegosecans jinxiuensis gen. nov. ＆ sp. nov., Epitrimerus sinensis sp. nov., Phyllocoptes glaucifoliae sp. nov., Diptilomiopus pomiferae sp. nov., and Vimola laxifloris sp. nov.. All of these new species are on the undersurface of leaves and cause no apparent damage to the host plants.展开更多
