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