Remarks
- Systematics: Koteja (1986) disputed the lectotype designation by Danzig (1983) and the synonymy of S. penium with this species. However, Danzig (1987) showed that the lectotype designation was in accordance with the International Code.
- Structure: Adult femali body elongate, with almost parallel sides, up to 3.5 mm long. Antennae 7-segmented. Legs very short in comparison with body, without translucent pores; large groups of minute discoidal pores present on cuticle posteriorly to each hine coxa. The number of multilocular pores and tubular ducts varies individually. The number of circuli varies geographically. Usually, only one circulus is present in this species. However, in the Central Asian mountain populations, the number of circuli varies from 1 to 3. (Danzig & Gavrilov-Zimin, 2015)
- Biology: Found at the bases of grasses and in leaf sheaths. Nymphs and ovipositing female were found in Poland during August-September (Koteja, 1969a). Life history discussed by Kosztarab & Kozár (1988F).
- General Remarks: Description and illustration of adult female by Williams (1962) (as Saccharicoccus penium Williams), Danzig (1980b) (as S. penium Williams), Kosztarab & Kozár (1988F) (as S. penium) and by Kwon et al. (2003a). Good decription of the adult female given by Borchsenius (1949) and by Tang (1992). .
