Kaganella tekini gen. et sp. nov. urn:lsid:zoobank.org:act: ABA3BE39-4E76-47C5-9AA9-A6D380B32B51 Fig. 8M–R Diagnosis Moderate to large rounded Kaganella gen. nov. with slightly pointed periphery. Etymology This species is named after Professor Dr U. Kagan Tekin (Hacettepe University, Ankara, Türkiye), in honour of his contributions to the knowledge of Radiolarian biostratigraphy. Material examined Five specimens were observed. 1 holotype and 4 paratypes are illustrated. Holotype (Fig. 8M–N) TÜRKİYE – Ankara • SE of Kutludüğün village, Kutludüğün Yayla, sample KDY–2; 39°52′07.4″ N, 33°06′23.4″ E; 20 Jun. 2023; Okuyucu and Akbaş leg.; KTÜN.CO–KDY2, KDY2.2–2. Paratypes (Fig. 8O–R) TÜRKİYE – Ankara • 1 spec.; same data as for holotype; KTÜN.CO–KDY2, KDY2.2–35 • 3 specs; same data as for holotype, sample KDY–1; 39°52′11.0″ N, 33°05′51.4″ E; KTÜN.CO–KDY1, KDY1.2– 27, KDY1.2–40, KDY1.3–35. Description Test moderate to large, involute, globular with slightly pointed periphery. Coiling at the beginning tightly glomospiral and finally planispiral. Spherical proloculus, 0.06–0.10 mm in diameter, followed by second chamber slowly enlarging in height through successive whorls. Initial part consists of approximately 23–25 whorls with relatively thin-walled. In the terminal part (planispiral coiled 3–4 whorls) the height of the whorls increases gradually. Adult specimens measure: D = 1.23–2.38 mm, w = 0.9–1.25 mm, the ratio w/D = 0.64–0.87, n.w. = 26–29. Wall calcareous, porcelaneous with some neosparitizations mainly in last whorls. The lumen of the tube is relatively narrow with rare flosculinisations. Aperture simple, terminal. Comparison Kaganella tekini gen. et sp. nov. differs from Rectogordiopsis kamuranaeformis gen. et sp. nov. by the smaller size of the test and rare perforations (comb teeth-shaped) in neosparitized wall which observed mainly in last whorls. Microfossil association The associated foraminiferal fauna is listed in Table 1 and illustrated in Figs 4–6. Range and distribution Middle Permian (late Capitanian) of the Elmadağ Olistostrome, Ankara City, Central Türkiye.
