The genus Tetrisia (Lepidoptera, Erebidae) was established by Walker (1867b: 186) for a new species of moth from Colombia. A homographic name, however, had been proposed almost five months earlier by Walker himself (1867a: 111‒112) for a genus of shieldbugs (Heteroptera, Plataspidae) from Singapore. In neither case did Walker give an etymology for the name Tetrisia, but Waldkircher et al. (2004) have speculated that for the heteropteran genus it might allude to the unusual four-segmented antennae, as most plataspids have five antennal segments. Insterestingly, however, Walker did not mention the number of segments in his description.
