Anal ring strongly sclerotized, without pores, circular, 34 (30–34) µm in diameter, with 6 strong short setae, each 7.5–8.0 µm long; anal ring situated on margin of dorsum, anterior part with a gap. Anal lobes weakly developed, each with two hair-like setae on dorsal surface, one seta 8, other 12–14 µm long; apical seta 92 (92–105); subapical setae 28–30 µm long. Cauda absent.

Comment. For diagnostic features of adult female, see generic diagnosis.

Etymology. The new species is named after Dr. Zeliha Düzgüneş, who was the first Turkish coccidologist to work on scale insects in Turkey.

Kotejacoccus Kaydan & Kozár , gen. nov.

Type species: Kotejacoccus turcicus Kaydan & Kozár sp. nov.

Generic diagnosis. Adult female. Ve n te r: Antennae 6 segmented; frontal tubercle absent. Venter with more than 30 groups of bilocular micropores. Legs normal; tibia longer than tarsus. Claw with a denticle. Macrotubular ducts, microtubular ducts, and cruciform pores absent. Multilocular pores, each with 5 loculi, sparse throughout most of venter, but numerous around spiracles. Setae all short and hair-like, except some setae spinose on margin.

Dorsum: With strong, capitate, (drum stick-shaped, sensu Henderson, 2007a, b) setae, mostly as long as those near margin. Anal lobes not well developed, dorsal surface of each lobe with four capitate dorsal setae. Anal ring sclerotized, not well developed, with six short, strong setae and a few pores. Cauda absent. Macrotubular ducts short, broad. Microtubular ducts narrow, long, few.

Comments. The genus Kotejacoccus is clearly distinct from all known eriococcid genera due to the presence of the large groups of bilocular-micropores on the venter. However, the new genus shows a few similarities with some genera from New Zealand and Australia. The Australian genus Phacelococcus Miller also has large groups of pores on the venter, but differs in having groups of quinquelocular pores rather than bilocularmicropores as on Kotejacoccus . In addition, Phacelococcus has spinose dorsal setae instead of the capitate setae in Kotejacoccus . Kotejacoccus also shows some similarities to the New Zealand genus Affeldococcus Henderson in having capitate dorsal setae and groups of pores, but Affeldococcus has groups of multilocular pores with bilocular pores in the centre on the dorsum instead of groups of bilocular-micropores on the venter. Affeldococcus also has reduced antennae and legs. Kotejacoccus also shows some similarity with the Australian genus Subcorticus Gullan which has large groups of spinulae (microtrichia) on the dorsum of the head, and a small group on the venter between antennae, but differs in having well-developed antennae and legs, in the presence of capitate setae on dorsum and groups of pores throughout the venter. There are some similarities with Acanthococcus stellatus (McDaniel, 1963) , which also occurs on oak, but this species has large groups of microtubular ducts on the venter, whereas on Kotejacoccus , the ducts are replaced by bilocularmicropores. A. stellatus differs by the presence of five-locular pores and by pointed spines spinose setae.

Etymology. The new genus is named after our late friend and colleague, Professor Dr. Jan Koteja, acknowledging his permanent help and brilliant work in coccidology.
