Abstract

A third species of the genus Sinhomidia is described from South China: S. uniseta sp. nov. This new species can be distinguished from the two other species of the genus by the following characters: colour pattern, single labial chaeta M, chaetotaxy on terga and ventral tube, unguis with three inner teeth, and 15 clypeal ciliated chaetae. Also, the chaetotaxy of the first instar of Sinhomidia is described for the first time in the present paper, and confirms the close relationship between Sinhomidia and Homidia. A key to species of Sinhomidia is provided.

Keywords: Entomobryinae; Sinhomidia uniseta sp. nov.; chaetotaxy; taxonomy.
