Comparison

Paracoccus solani is similar to P. lycopersici by having 7 or fewer pairs of cerarii, dorsal oral-rim tubular ducts scattered over surface, multilocular pores absent from thorax. Paracoccus solani can be distinguished (characters of P. lycopersici are in parentheses) by lacking oral collars laterad of anterior spiracles (present).

U.S. quarantine notes

This species was intercepted at U. S. ports-of-entry 35 times between 1995 and 2012, with specimens originating from Chile, Cuba, Ecuador, Jamaica and Mexico. ScaleNet lists hosts in 12 plant families. It is commonly intercepted on rosemary and sage (Lamiaceae – Mint family), Leucaena (Fabaceae) and pepper plants. We also have examined quarantine specimens from Mexico (Mentha, Rosmarinus, Salvia).ScaleNet distribution records for P. solani include Australia (Queensland) in the Australasian zoogeographic region, Mexico and the The United States of America (Arizona) in the Nearctic zoogeographic region and Costa Rica, Galapagos Islands and Peru in the Neotropical region. ScaleNet distribution records for P. mexicanus include only Mexico. Several species of Paracoccus other than P. brunerae, P. ferrisi, P. herreni, P. interceptus, P. lycopersici, P. marginatus, P. mexicanus and P. solani have been intercepted at U. S. ports-of-entry including: P. hamoni (Mexico, on Cephalocereus); P. circuliprivis (Mexico, on Thomsoniella); P. invectus (Thailand and India, on orchids, including Dendrobium); and P. reductus (Mexico, on Yucca).
