Sarothrias sinicus: A new species of Jacobsonid Beetle from Tibet.

Jacobsonids are a small group of minute elongate yellowish brown Beetles, of uncertain taxonomic placement; different entomologists feeling that the group are more closely related to different groups of Beetles. The family is split into three genera with a total of 21 described species, the largest genera, Sarothrias, currently containing thirteen species, twelve of which are found in equatorial regions from the Seychelles and South India to the west to Australia and Fiji in the east, with the one non-equatorial species being found in northeast India.

In a paper published in the journal ZooKeys on 16 April 2015, Wen-Xuan Bi of the Key Laboratory of Zoological Systematics and Evolution at the Institute of Zoology of the Chinese Academy of Sciences, Chang-Chin Chen of the NPS office of the Tianjin New Wei San Industrial Company, Limited and Mei-Ying Lin, also of the Key Laboratory of Zoological Systematics and Evolution at the Institute of Zoology describe a new species of Sarothrias, from Medog County in Tibet.

The new species is named Sarothrias sinicus, meaning ‘Chinese’, as it is the first member of the genus or family known from China. The species is described from a single male specimen, 2.2 mm in length and dark brown in colour, collected from subtropical evergreen broadleaf forest at an altitude of 1850 m.
