Remarks

• Systematics: Paracoccus galzerae is similar to P. decorus in (i) lacking a circulus and (ii) having multilocular disc pores present on the venter of the thorax. P. galzerae can be distinguished from P. decorus in having (i) two sizes of oral collar tubular ducts on the ventral abdominal segments (one size in P. decorus), (ii) clusters of oral collar tubular ducts next to the anal lobe cerarii (absent in P. decorus), and (P. galzerae is closest to P. solani in (i) having two sizes of oral collar tubular ducts on the ventral abdominal segments, (ii) lacking oral collar tubular ducts on the ventral margins of the thorax, and (iii) having oral rim tubular ducts in rows across most abdominal segments of dorsum. However, P. galzerae can be readily distinguished from P. solani in having (i) multilocular disc pores on the dorsum (absent in P. solani), (ii) multilocular disc pores on the venter of the thorax and on the margin of the abdomen (no multilocular disc pores on the thorax in P. solani, multilocular disc pores never reaching margin in P. solani), and (iii) number of multilocular disc pores on abdominal segments larger in P. galzerae than in P. solani (in P. solani as follows: I–III 0, IV 15, V 24, VI 37, VII 45, VIII–IX 23 according to the original description by Ezzat & McConnell 1956). The most important character to distinguish these two species is the presence or absence of multilocular disc pores on the margin of the abdominal segments and on the dorsum (multilocular disc pores present on margin and dorsum in P. galzerae, lacking in P. solani). Although the number of multilocular disc pores can change with environmental conditions, the position of the pores is consistent in each species.
