Comments. In the original description of Euryporus argentatus , Fauvel (1881) clearly mentioned a single type specimen from "Moeara Laboe" [= Moearalaboeh, now Propinsi Jambi, Indonesia, 1°29'0"S, 101°3'0"E]. Based on the habitus (Fig. 2) and other diagnostic characters, the holotypeand other specimens of Euryporus argentatus from the collection of NCBN are conspecific and can be clearly identified as a species of the genus Tympanophorus Nordmann, 1837. With the possible exception of Tympanophorus schenklingi Bernhauer, 1912 from the Afrotropical region, Tympanophorus (e.g., illustrated redescription in Naomi 1983) is monophyletic ( Schillhammer 2004).

It is noteworthy that long after the description of Euryporus argentatus , Fauvel (1902) did recognize the correct affiliation of that species. In a short note on page 42 he mentioned " Tympanophorus argentatus Fvl. (rugosus Waterh.)", apparently meaning a synonymy of his species with Tympanophorus rugosus (C. Waterhouse, 1884). This so vaguely annotated transfer of Euryporus argentatus to Tympanophorus was overlooked by later authors. For example Herman (2001) lists both Euryporus argentatus Fauvel, 1881 as a valid species and " Tympanophorus argentatus Fauvel", erroneously, as nomen nudum. Synonymy of Tympanophorus argentatus (Fauvel, 1881) and T. rugosus (C. Waterhouse, 1884) remains to be verified.
