Interpretive Summary: The jumping plant, louse genus Pachypsylla, contains species that make galls on hackberry trees. The purpose of this manuscript is to clear up confusion in the formal scientific names of the species. The fourteen recognized species in the genus Pachypsylla are: venusta, celtidisasterisca, celtidisgemma, celtidiscucurbita, celtidisitneneris, celtidispubescens, celtidisumbilicus, celtidisglobula, celtidismamma, cohabitans, dubia, pallida and tropicala. Having the correct scientific names is important because it links to the ecological literature. The species of this genus are important because some of the species are found in citrus groves where they superficially resemble and are sometimes confused, with the Asian citrus psyllid. Even though they do not breed on citrus, by feeding on citrus they are potential vectors of citrus diseases.
The nomenclatural problems with the hackberry gall psyllid species names are rectified. The genus Pachypsylla Riley, 1883, type species, Psylla venusta Osten-Sacken, includes 14 nominal species. These are: Pachypsylla venusta (Osten-Sacken, 1861); P. celtidismamma Riley, 1875; P. celtidisgemma Riley, 1885; P. celtidisasterisca Riley, 1890; P. celtidiscucurbita Riley, 1890; P. celtidisglobula Riley, 1890; P. celtidispubescens Riley, 1890; P. celtidisumbilicus Riley, 1890; P. celtidisvesiculus Riley, 1890; P. celtidisinteneris Mally, 1894; P. dubia Patch, 1912; P. pallida Patch, 1912; P. tropicala Caldwell, 1944; and P. cohabitans Yang & Riemann, 2001.
