It cannot be ruled out that P. tacta is a bona species, due to its distribution and genetic divergence from Asian taxa ( Balaji et al. 2021), nevertheless we retain its synonymy with P. securis View in CoL until comparative material from Australia is studied and phylogenetic analyses sampling both Indomalayan ( P. securis View in CoL ) and Australian ( P. tacta ) specimens, are completed.

Taxonomic note. Although the rather variable specimens of P. pennatula (Indian subcontinent) and P. securis (Java) are indistinguishable based on their habitus and the male genitalia configuration, the comparison of the female genitalia of specimens from Java and the Indian subcontinent revealed several distinctive characters between the two Asiatic species. These characters are expressed by the noticeably longer papillae anales and pseudopapillae, the medially deeply notched distal margin of the ostium bursae and the very narrow and long, thread-like signum bursae of the Javan P. securis in contrast to the gently arched ostial margin and the shorter and markedly broader, elliptical plate of the signum bursae in the Indian P. pennatula ( Figs 40–42 View Figures 40–45 ). In spite of the fact that numerous online sources list P. securis as a valid taxon (e.g., www.afromoths.net, www.funet.fi), we could not trace the taxonomic act reviving P. securis from synonymy with P. pennatula and consider the former to remain in synonymy with the latter following Bryk (1934). The clarification of the identity of P. securis is rather problematic as the primary type of P. securis together with many other Hübner specimens was probably destroyed in a fire during the Vienna Revolution in 1848 ( Gilligan & Wright 2013). Thus, the identity of this species cannot be confirmed with full certainty, although it is highly likely that Psalis specimens from such a welldefined type locality as Java, belong to P. securis . As it cannot be ruled out that primary type specimens of P. securis have survived the fire and currently reside in the immense collections of the Natural History Museum in Vienna, a neotype designation would be unsound; however, based on examinations of topotypical specimens we tentatively confirm the distinctness of P. securis stat. rev. and is treated as a valid species. Further questions that require answering include whether P. securis is confined to the island of Java or whether it has a more extensive range expanding into India and/or Australia, and, vice versa in the case of P. pennatula . In order to elucidate the accurate distributions of these Asiatic species and establish if P. pennatula and P. securis are indeed allopatric taxa, extensive morphological and genetic studies are required which are beyond the scope of this present paper.
