The pseudoscorpion genus Shravana Chamberlin, 1930, belonging to the family Ideoroncidae Chamberlin, 1930, currently contains 13 species. To date, no ideoroncid species has been recorded from China.
The family Ideoroncidae Chamberlin, 1930 is reported from China for the first time. A new species of the genus Shravana Chamberlin, 1930, collected from Xizang Autonomous Region, China, is described under the name of Shravana zhui Gao & Zhang, sp. nov. on the basis of both sexes. The finding of this new species expands the distribution range of this family in Asia.

The pseudoscorpion family Ideoroncidae was first recognised by
The genus Shravana was erected by
Due to a lack of comprehensive fieldwork, up to the present, no Shravana species has been reported from China. Shravana zhui sp. nov. is presented here as a representative of the family Ideoroncidae recorded in China for the first time.
The specimens are preserved in 75% alcohol and deposited in the Museum of Hebei University (MHBU) (Baoding, China). Photographs were taken with a Leica M205a stereomicroscope, equipped with a Leica DFC550 camera and the LAS software v. 4.6 and the Leica M205A stereomicroscope with a drawing tube was used for drawings and measurements. All measurements are given in mm unless noted otherwise. The chela and the chelal hand were measured in the ventral view. Detailed examination was carried out with an Olympus BX53 general optical microscope. Temporary slide mounts were made in glycerol.
Terminology and mensuration largely follow
Adult male. Carapace and tergites dark brown, chelicerae, pedipalps and legs yellowish-brown (Fig.
Setae: generally long, straight or slightly curved and acicular.
Cephalothorax (Figs
Shravana zhui sp. nov., holotype: a carapace (dorsal view); b left chelicera (dorsal view); c rallum; d galea; e chelal fingers (prolateral view); f left palp (minus chela, dorsal view); g leg I (lateral view); h leg IV; i tarsus IV (lateral view). Scale bars: 0.10 mm (b–d); 0.50 mm (a, e–h).
The new species share the character of presence of only two trichobothria in the b region with S. pohli (Mahnert, 2007) and S. socotraensis (Mahnert, 2007); it differs from them by the presence of 21 trichobothria on the fixed chelal finger and hand, whereas S. pohli has 23–24, S. socotraensis has only 20 trichobothria (

This species is named in memory of Prof. Mingsheng Zhu (1950-2010), a famous arachnologist from China, who made a great contribution to the study of Chinese arachnology.
The new species is known only from Xizang Autonomous Region, China.
Shravana zhui sp. nov. is the first member of the family Ideoroncidae to be discovered in China, which expanded the distribution range of this family in Asia; two specimens were collected on the wet inner side under stones at a relatively higher elevation (3062 m).
