Dicaelus politus Dejean, 1826

Dicaelus politus Dejean, 1826: 391. Type locality: «Amérique septentrionale" (original citation), restricted to "Uniontown, Penns[ylvania]" by Lindroth (1969a: 951). One syntype in MHNP (Lindroth 1955b: 18).

Dicaelus leonardii T.W. Harris, 1828d: 132. Type locality not stated. Possible syntype(s) in MCZ. Synonymy established by Harris (1829: 1), confirmed by Ball (1959: 110). Note. Harris’s collection contains two specimens under the name Dicaelus politus , both from New Hampshire. Ball (1959: 110) reported the presence of one syntype in MCZ, probably referring to the ♂ specimen in LeConte’s collection labeled "[pink disc] / D. politus Dej. Leonardii Harris. [handwritten]."
