The erythraeid species can be assigned with larva or adult only, or both under current Erythraeidae taxonomy. The present study describes two new erythraeid species from Yunnan-Guizhou Plateau (Oriental region). Marantelophus neodubifurcatussp. nov. is based on larvae that were off-host when collected, while Erythraeus (Zaracarus) mossesussp. nov. is based on a female adult, which was preying on an ant when collected, and larvae which were her offspring. The genus Marantelophus is divided into two species groups based on the odontus with or without a subterminal tooth, and M. neodubifurcatussp. nov. belongs to the group with the subterminal tooth. The larval members of the subgenus Erythraeus (Zaracarus) are divided into five species groups, and E. (Z.) mossesussp. nov. belongs to the group with the characters such that AL without swelling near bases, and fn BFe = 2-2-2. [ABSTRACT FROM AUTHOR]

Four new species, Abrolophus quadrapexicis Xu & Jin sp. nov., Grandjeanella dianensis Xu & Jin sp. nov., Leptus (Leptus) trisolenidionus Xu & Jin sp. nov. and Hirstiosoma tibetensis Xu & Jin sp. nov. are described and illustrated based on larvae. The species Hirstiosoma sadafae (Amin, Khanjani & Nadri) comb. nov. is transferred from the genus Sphaerotarsus to Hirstiosoma based on gnathosoma with two pairs barbed hypostomalae (as and bs), as and bs almost equal in length. H. tibetensissp. nov. and G. dianensissp. nov. are from the Tibetan Plateau (Qinghai-Tibet Plateau), a unique geographical unit of the highest altitude in the world. The described H. tibetensissp. nov. from the Tibetan Plateau represents a newly recorded subfamily from China, namely Hirstiosomatinae (Smarididae) with the genus Hirstiosoma. The genus Grandjeanella including six species distributed in Australia, New Zealand and Indonesia (Sulawesi), is new to China and the Eurasian continent as G. dianensissp. nov. found in the southern Tibetan Plateau (Gaoligongshan National Natural Reserve). In China Abrolophus has been known from the Oriental realm, A. quadrapexicissp. nov. makes it cover both the Palaearctic and Oriental realm of China. L. (L.) trisolenidionussp. nov. belongs to the phalangii species group and torresianus species subgroup, which contains three species previously known in Oceania (Australia) and South America (French Guiana) and here is the first report in Asia (China).

This paper reports two new species of genus Neoscirula, namely, N. bambus Chen & Jin sp. nov. from Guangxi Zhuang Autonomous Region and N. pananensis Chen & Jin sp. nov. from Zhejiang province, which are described and illustrated. A key to adult females of Neoscirula species of the China is provided. [ABSTRACT FROM AUTHOR]

Diplogyniopsis fluctuosumsp. nov. associated with passalid beetles is described based on females from China on undermined passalid beetles, as well as on females and males from Thailand on Aceraius helferi (Coleoptera: Passalidae). The species represents the second known species of Diplogyniopsis Trägårdh, prompting us to redefine the genus diagnosis. [ABSTRACT FROM AUTHOR]

A brief introduction of Chinese Limnesiidae taxonomy is provided. Adults of two new species, Limnesia (Limnesia) lupingae Li & Guo sp. nov. and Limnesia (Limnesia) macrophthalma Li & Guo sp. nov., from Heilongjiang and Hubei provinces respectively, are described in detail. Subtle structures are recorded with scanning electron micrographs. In addition, deutonymphs of two new species are also described in detail and compared with the adults in discussion.
