Notes. Drapetes exstriatus has a somewhat convoluted nomenclatural history as seen above. This led to continued use of D. geminatus (e.g., Bonvouloir 1859; Gerstäcker 1860; Schaeffer 1916; Blanchard 1917; Leng 1920; Schenkling 1928; Downie and Arnett 1996), a name lost to homonymy in 1834. An important aspect of the nomenclatural confusion of this species is that several authors published names that were nomina nuda or are unavailable because they were given only as synonyms (ICZN 1999, Art. 11.6). These are documented here solely for the clarification of historical names, indicating their disposition, and are not intended for validation:

1. Elater bimaculatus by Melsheimer (1806: 43) is a nomen nudum. This name was also given as a synonym by Say (1825) and Gerstäcker (1860), and is not available (ICZN 1999, Art 11.6).

2. Elater americanus by both Harris (1833, 1835) and Dejean (1833, 1836) is a nomen nudum in all instances.

3. Elater rufinotatus by Harris (1835) was published as a synonym and is not available (ICZN 1999, Art 11.6)

4. Drapetes americanus by Dejean (1833, 1836) is a nomen nudum. Gerstäcker (1860) listed the name as a synonym and is not available (ICZN 1999, Art 11.6).

5. Lissomus cinctellus by Gerstäcker (1860) was listed as a synonym and is not available (ICZN 1999, Art 11.6).

When Say (1825) described E. geminatus he listed E. bimaculatus Melsheimer (1806) , a nomen nudum, as a synonym and compared it to the then E. bimaculatus Rossi of Europe. The homonymy correction was made when Say (1834) published E. exstriatus and stated “I change the name, as that of geminatus was previously given by Germar [1824] to a Brazilian species.”

Elater nitidus F. V. Melsheimer (1806) nomen nudum, was validated by his son F. E. Melsheimer (1844). The use of “ nitidus ” as a subspecies name by Downie and Arnett (1996) is without foundation as it represents only a color variation, as recognized for over 210 years, and not a definable geographically or otherwise delimited population.
