Remarks

• Systematics: Volvicoccus stipae was previously included in the genus Mirococcopsis Borchsenius, 1948. Because of the presence of characteristic oral collar tubular ducts (with the collar placed in the middle part of the duct) this species was transferred to the genus Volvicoccus by Gavrilov in 2007. (Rosa & Simon, 2011) The probable synonymy of Mirococcopsis stipae was mentioned by Matile-Ferrero (1983), without, however, formal synonymization. Danzig & Gavrilov, 2013a, examined the type material of both the nominal species and also found no essential distinctions between them.
• Structure: Female. Body strongly elongate, reaching 4.5 mm in length. Antennae 7-segmented. Legs fine and rather short. Hind coxa widened, with numerous microtubular ducts. Ostioles represented by only posterior pair, poorly visible. Circulus-1, small, rounded or oval. Anal ring formed by inner row of oval pores and by outer row formed by several pores at each side. Multilocular pores with 8-13 (usually 10) loculi, forming transverse stripes on 3 posterior abdominal sternites and small groups along ventral margin of body; singular multilocular pores present on posterior abdominal tergites. Trilocular pores numerous over entire surface of body. Simple pores absent. Tubular ducts forming wide stripe along ventral margin of body and transverse rows and stripes on abdominal segments. Instead of last pair of cerarii, 2 thick setae present, not surrounded by congestions of trilocular pores. Entire surface of body with sparse fine flagellate setae. (Danzig & Gavrilov, 2013a)
• Biology: Living under the leaf sheaths of the host plant.Occurring in the leaf sheaths and more rarely on the roots of the host plant.
• General Remarks: Good description and illustration of the adult female given by Goux (1945).Good description and illustration of the adult female given by Ter-Grigorian (1973) and by Tereznikova (1975). Good description of the adult female given by Borchsenius (1949) and by Tang (1992).
