Several specimens are figured to show the variability of this species. Taxonomy: Smith clarified the synonymy of the species, and synonymized the type species of Neostromboceros, Stromboceros (Neostromboceros) metallica Rohwer, 1912, with N. albicomus. Hitherto, the species is known from Malyasia, Philippines, Singapore, Thailand, Vietnam (Smith et al. 2002). Stromboceros albicomus KONOW, 1900. Type locality: Malaysia: Perak (4.100°N 101.016°E). Synonyms: Stromboceros cenchralis KONOW, 1908. Type locality: Philippines: Palawan Island (9.600°N 118.600°E) Stromboceros (Neostromboceros) metallica ROHWER, 1912.
