Remarks

• Systematics: 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.

  Danzig & Gavrilov-Zimin (2015) determined from the original descriptions of the species of Tibetococcus differ from each other "only in the number of circuli" and "the absence of any other morphological and ecological differences between discussed Chinnese (sic,) 'species' clearly denotes the variation of circuli number in the same population and as a result, ..... consider T. triticola and T. nyalaiensis as junior synonyms of T. dingriensis. In addition, they stated that these species only differ from Mirococcopsis teberdae" in the number of antennal segments (7-8 instead of 6) and in more numerous multiloular pores. Therefore, they determined that these quantitative characters were not enough to support "species independency" and they considered them as a substecies of M teberdae.

• Biology: Living on roots of its host plant.
• General Remarks: Good description and illustration of the adult female given by Tang (1987, 1992).
