World Distribution — This species has a cosmopolitan distribution and reported mostly in tropical and subtropical areas of the world ( Demite et al. 2022) and Maldives (this study). Remarks — Morphological characters and measurements of the Maldivian specimens are identical to the original description and subsequent redescriptions ( Schicha 1987 ; Denmark and Muma 1989 ; Zannou et al. 2007 ; Navia et al. 2014 ; Karmakar et al. 2017 ; Ferragut and Baumann 2019 ; Liao et al. 2020).
