Diagnosis: This species can be distinguished from other Taiwanese Psammoecus species by the short oval habitus and the black elytra with yellow maculae.
Distribution: Taiwan; Japan; Philippines; India; Sri Lanka; Malaysia; Indonesia; Madagascar; France (Réunion); Seychelles.
Remarks: Pal (1985) and Karner (2012) provided redescriptions of this species, and Yoshida and Hirowatari (2014) provided a detailed description of male genital structure of this species. In this study, we examined morphology-including male genitalia of P. stultus type specimens - and found P. stultus should be synonymized with P. simonis.
Grouvelle (1892) initially described this species as ‘simonis’, but later Grouvelle (1908) referred to it as ‘simoni’, and all subsequent authors have used the latter spelling (Hetschko 1930; Pal 1985; Sen Gupta and Pal 1996; Hirano 2009 2010; Karner 2012 2014; Yoshida and Hirowatari 2014 2015). According to Article 33 of the International Code of Zoological Nomenclature, if the original spelling was changed without demonstrably intentional emendation, the subsequent spelling should be regarded as incorrect and not an available name except in the case that the subsequent spelling is in prevailing usage. Otherwise, Article 23.9.1 of the code states that prevailing usage of the junior synonym must be maintained when the senior synonym has not been used as a valid name after 1899, and the junior synonym has been used for a particular taxon as its presumed valid name in at least 25 works, published by at least 10 authors in the immediately preceding 50 years and encompassing a span of not less than 10 years. In the case of this species, the subsequent spelling ‘simoni’ changed without demonstrably intentional emendation should be regarded as an incorrect spelling, and it has not been in prevailing usage like the requirement in the Article 23.9.1 of the code. Therefore, ‘simonis’ is deemed to be valid name of this species.
