Etymology: In honour of Dr. Nikolai N. Kalandadze, who collected the specimens.
Type material: Holotype: PIN 5268−1 View Materials ( Figs. 2–4 View Fig View Fig View Fig ), a partial shell missing its right and posterior periphery . Paratypes: PIN 5268−2 View Materials ( Figs. 5 View Fig , 6 View Fig ) , a partial shell including left lateral fragment of the carapace and left half of the plastron; PIN 5268−3 View Materials ( Fig. 5 View Fig ) , fragment of a carapace, including pygal and sutured fragments of peripherals 11; PIN 5268−4 View Materials ( Fig. 5 View Fig ) , left bridge peripheral. PIN 5268−3 View Materials and PIN 5268−4 View Materials may belong to the same individual as PIN 5268−1 View Materials or PIN 5268−2 View Materials . There are a number of other shell fragments belonging either to PIN 5268−1 View Materials or/and PIN 5268−2 View Materials .
Type locality: Khara Khutul (= Khara Khutul Ula; = Khar Hötöl Uul), 90 km SW from the town of Sainshand, Dornogov Aimag ( Eastern Gobi ), Mongolia. All materials were collected in 1976 in course of Soviet−Mongolian Paleontological Expedition by Dr. Nikolai N. Kalandadze .
Type horizon: Lower part of the Bainshire Formation, Upper Cretaceous (Cenomanian–lower Turonian) ( Kalandadze and Kurzanov 1974; Shuvalov and Chkhikvadze 1975; Shuvalov 2000; Suzuki and Narmandakh 2004).
Included species.— Type and only species.
Diagnosis.—A nanhsiungchelyid which can be differentiated from all other members of the family by relatively small size (except Zangerlia testudinimorpha and Z. ukhaachelys ), shallow nuchal notch formed by small and trapezoid nuchal and peripherals 1 (except species of Basilemys ), narrow neurals (except Basilemys nobilis and B. variolosa ), contact of costals 7 at midline posterior to neural 7 (except B. nobilis ), vertebral 1 widened anteriorly, in contact with marginals 2 (except B. nobilis and B. variolosa ), presence of gular and anal notches, anterior plastral lobe covered by carapace in dorsal view and gulars weakly extend onto shallow anterior plastral lip. Besides that it can be differentiated from species of Basilemys by vertebral and pleural scales do not strongly overlap onto peripherals and four pairs of inframarginals present which fully separate marginals from plastral scales; from Hanbogdemys orientalis by costiform processes of nuchal very small; and from species of Zangerlia by posterior peripherals flared, not shortened.
Distribution.—Lower part of the Bainshire Formation, Cenomanian–lower Turonian, Khara Khutul, Mongolia.
