The species name, an adjective, is derived from the Chinese pronunciation of “not thailandensis . ” Remarks. This species resembles H. thailandensis in having a similar aedeagus, but the latter has the vertex in males rounded and slightly upturned apically, the ocellus separated from the corresponding eye by its own diameter, and a small gonopore located far from the base of the process.
