The specific name “ flavida ” refers to the colour of this species, which is mostly pale yellow.

Remarks.

The new species is similar to H. plumosa (Sasakawa), but it differs in having a yellowish head, indistinct stripes on the scutum, and fully fused cerci. In H. plumosa (Sasakawa), the head is yellow, the thorax is more distinctly striped, and the cerci are separated (Sueyoshi 2006).
