Miridiba hanoiensis – Coca-Abia 2008: 680 . Diagnosis See Keith (2006) . Remarks Keith (2006) described Miridiba hanoiensis based on only one male specimen designated as holotype . This species shows features of external morphology that characterize Miridiba . On the other hand, the male genitalia described and illustrated by Keith (2006) do not provide enough data on the genital morphology, making it difficult to specify the morphotype to which this species belongs. Nevertheless, the acicular expansions at the base of the aedeagus described by Keith (2006) , which could be ventral branches, and the antenna 9-segmented lead us to believe that this species could belong to morphotype I “ Trichophora ”. Distribution Vietnam ( Hanoi ).
