Remarks

• Systematics: Among the Iranian species, C. viticola is most similar to Spilococcus alhagii, both species having cup-shaped translucent pores on the hind tibia. C. viticola can readily be distinguished from S. alhagii in having only two true cerarii (15 or 16 pairs in S. alhagii). Some cerarii-like structures have been observed on the margin on some specimens of C. viticola, but there are never more than 11, and C. viticola has a greater number of oral-rim ducts on the dorsum than on S. alhagii; C. viticola also has oral collar tubular ducts on the dorsum of the last abdominal segment, which are absent on S. alhagii. (Moghaddam, 2013)

  The comprehensive book of Danzig and Gavrilov (2015) examines many of the character systems that have become standard in certain taxonomic analyses worldwide. Some of their conclusions are in direct contrast to the general thinking of past coccidologists. They question the utility of such characters as the presence or absence of the anal bar, the cluster of multilocular pores and tubular ducts on the margin of the prothorax, the number of cerarii, the presence of auxiliary setae in the cerarii, the presence of black pigments in the body. Because of their different interpretation of the character systems, there are a number of fairly extensive synonymies. Although they have presented their rationales for making these changes, we hesitate to accept all of them without more definitive information. It would be highly useful to have integrated morphological and molecular analyses before implementing synonymies. Practically, once species have been synonymized, the information and literature about each synonym becomes more and more difficult to trace over time. Thus, it is important to be as certain as possible about synonymy actions.

• Structure: Adult female body oval, light pink, with two white filaments at end of abdomen. Slide-mounted adult female elongate oval. Anal lobes well developed. Antennae each with 8 segments. Legs well developed; hind leg with large translucent pores on tibia; tarsal digitules each pointed at tip and shorter than claw.(Moghaddam & Watson, 2022)
• Economic Importance: C. viticola is the most important pest of grapevine in some parts of Fars, Iran. The damage caused by this pest has increased in recent years (Fallahzadeh et al. 2010). Fallahzadeh & Japoshvili (2010) described the parasitoid Gyranusoidea iranica Japoshvili and Fallahzadeh (Hymenoptera: Encyrtidae) on C. viticola
