Diagnosis See Keith (2020) . Remarks According to the original descriptions ( Keith 2020 ), this species shows features that characterize Miridiba on head (punctures, frontal carina, labrum); legs (longitudinal carina of foretibia; tufts of first four tarsomeres) and genitalia (parameres with branches). Unfortunately, we were unable to study the types and the male genitalia illustrated by Keith (2020) does not allow us to assign this species to any genital morphotype. Therefore, M. enigmatica is considered as species incertae sedis within the genus Miridiba . Distribution Vietnam .
