The first description of alate and supplementary description of soldier of Reticulitermes aculabialis Tsai et Hwang (Isoptera, Rhinotermitidae)

The subterranean termite Reticulitermes aculabialis was firstly described from the soldier caste in 1977 and diagnose from the imago has been difficult due to the lack of description of alate. In this paper, a detailed description of alate for R. aculabialis is presented, including additional data to soldiers. The data are chiefly based on the external morphology of R. aculabialis imago, which has never been described before. All the samples of alates and soldiers were collected in Xi’an, Shaanxi province, China. All of the essential specific characteristics are illustrated for identification purposes.
