Oral-rim tubular ducts usually present ventrally on head and anterior thorax; multilocular pores absent from lateral areas of abdominal segments; 5-7 pairs of cerarii; multilocular pores on segments IV-VIII, absent from thorax and head; cluster of oral-collar tubular ducts absent laterad of anterior spiracle; oral collars absent laterad of mid pair of legs; circulus normally present, rarely absent; cerarii with 2 conical setae; oral-rim tubular ducts covering dorsum, absent from segment VIII; anal bar present.


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).
