Remarks. Opusia indica ( Alcock, 1900) was described by Alcock (1900) from Karachi, Pakistan as Tylodiplax indica . Ng et al. (2009) recently have described the monotypic genus Opusia and recorded the species O. indica from Iraq. According to Ng et al. (2009), Opusia is mainly characterized by a broadly ovate carapace without distinct ridges on dorsal surface (such ridges are seen in Tylodiplax ), anterolateral margin making no angle with posterolateral margin, the anterior part of the first two thoracic sternites of males are rounded (v.s. triangular in Tylodiplax ), a distinct complete suture between male abdominal segments, segments 3-5 functionally fused, abdominal segment 5 basically constricted, male G1 ending in a conical apex. Detailed morphological and taxonomic remarks for this genus and allied genera are given by Ng et al. (2009).
