Status of Zonantes mississippiensis Werner, 1990 . I examined one of the two two females from Mississippi, on which Werner based his original description. This single ♀ paratype (Collection E. G. Riley), which I re-prepared, is very similar in its external morphology (outside of dimorphic characters), to most Syzeton ouachitanus ( Werner, 1990) specimens that I have observed. In most specimens, notably, the elytra are pale brown, with a hardly visible transversal darkening in their posterior half ( Figure 1a View FIGURE 1 , not mentioned in the key because too subtle). Only some specimens of S. ouachitanus ( Werner, 1990) have a more pronounced transversal midband on the elytra ( Figure 1m View FIGURE 1 ). In addition, in this single ♀ paratype of Zonantes mississippiensis Werner, 1990 , the apex of the last visible tergum corresponds precisely to the description given by Werner (1990) for the females of S. ouachitanus ( Werner, 1990) , with 5–6 teeth. It is surprising that Werner gave no details on the last visible tergum for the two females of Zonantes mississippiensis Werner, 1990 that he used for his original description. I therefore propose the following synonymy: Zonantes mississippiensis Werner, 1990 = Syzeton ouachitanus ( Werner, 1990) , syn. nov.

Because the two taxa were described in the same paper, the question of priority arises. Leaning on ICZN Art. 24.2 ( International Commission on Zoological Nomenclature, 1999), I decided to maintain Syzeton ouachitanus ( Werner, 1990) as the senior name for two reasons. First, its description precedes that of Zonantes mississippiensis Werner, 1990 in Werner’s paper. Second. in the interest of nomenclature stability, as Zonantes mississippiensis Werner, 1990 is described from only 2 females and much less information is available for this taxon.
