Living a lie: The truth behind Isohydnocera curtipennis (Newman) and other historically confused species of Phyllobaenus Dejean, with the description of the new genus Neohydnocera (Coleoptera: Cleridae: Clerinae: Hydnocerini: Hydnocerina)

Abstract

Taxonomic changes in the New World Hydnocerina (Coleoptera: Cleridae: Clerinae: Hydnocerini) at the species and genus level are presented. Phyllobaenus suturalis (Klug, 1842) and Hydnocera limbata Spinola, 1844 are designated junior synonyms of P. pallipennis (Say, 1825), new synonymy. Phyllobaenus nigrescens (Schaeffer, 1909) is designated a junior synonym of P. verticalis (Say, 1835), new synonymy. Isohydnocera curtipennis (Newman, 1840), P. lineaticollis Spinola, 1844, and Clerus brachypterus Klug, 1842, are re-established as junior synonyms of P. verticalis (Say, 1835), status reinstated, and I. curtipennis is accordingly reassigned to Phyllobaenus Dejean as P. curtipennis, new combination. Cephaloclerus Kuwert, 1893 is removed from synonymy under Phyllobaenus and re-elevated to genus rank, status resurrected. The genus Isohydnocera Chapin, 1917 is designated a junior synonym of Phyllobaenus Dejean, 1833, new synonymy, and I. liebecki Wolcott, 1928 is designated a junior synonym of I. tabida (LeConte, 1849), new synonymy. The new genus Neohydnocera is described to accommodate species formerly known as Isohydnocera Chapin. Hydnocera longicollis Zeigler, 1844 is removed from synonymy under I. curtipennis, status resurrected, and recognized as Neohydnocera longicollis, new combination. The following new combinations for species previously considered Isohydnocera are presented: Neohydnocera aegra (Newman, 1840), new combination, Phyllobaenus albocinctus (Horn, 1871), new combination, N. brunnea (Chapin, 1917), new combination, N. californica (Barr, 1966), new combination, N. chiricahuana (Knull, 1949), new combination, P. cryptocerinus (Gorham, 1883), new combination, N. gerhardi (Wolcott, 1910), new combination, N. mima (Wolcott,1928), new combination, N. nigrina (Schaeffer, 1908), new combination, N. ornata (Wolcott, 1908), new combination, N. pusilla (Schaeffer, 1909), new combination, P. schusteri (LeConte, 1866), new combination, N. tabida (LeConte, 1849), new combination, and P. tricondylae (LeConte, 1849), new combination.
