摘要根据1990年、2000年和2004年的考察资料和对新西伯利亚的标本进行的分析，对俄罗斯西伯利亚图瓦的齿科动物区系进行了研究。图文尼蜻蜓目名录目前包括47种。在南部的乌布苏-努尔洼地记录了29种（2种就在那里）;在中部的图文尼亚洼地34种（6种就在那里），在托贾洼地32种（9种就在那里）。Todzha的针叶林地区较为潮湿，与图瓦的干旱地区被奥布鲁切夫山脉隔开，该地区的动物群包含一些森林物种，但缺少图瓦其他地方发现的7个物种。尽管托贾位于东北部，但其动物群显示出更西部的特征，包括一个有很高比例的雄色雌性和雄性的Calopteryx splendens种群，其翅膀的颜色一直到尖端。托贾还居住着Enallagma c。cyathigerum，腹部呈黑色，而在中部Tuvinian和Ubsu-Nur洼地，E. C. risi发生了。在图兰和上Kaa-Khem盆地，这两个类群之间的过渡发生。在Todzha，Somatochlora exuberata和S. metallica abocanica同域分布，没有中间型，生境隔离，从而证明了它们作为独立种的地位。Todzha也居住着Ophiogomphus obscurus，而图瓦的其他地方则有O。棘角虫
Abstract The odonate fauna of Tuva in Siberia, Russia, is documented, based mainly on data from expeditions in 1990, 2000 and 2004, and examination of collections preserved in Novosibirsk. The checklist of Tuvinian Odonata presently includes 47 species. In the southern Ubsu-Nur depression 29 species were recorded (two just there); in the Central Tuvinian depression 34 species (six just there) and in the Todzha depression 32 species (nine just there). The fauna of the more humid taiga region of Todzha, separated from the arid remainder of Tuva by the Obruchev Mts, contained some forest species but lacked seven species found elsewhere in Tuva. In spite of Todzha's position in the north-east, its fauna showed a more western character and included a population of Calopteryx splendens with a high proportion of androchromic females and males with wings coloured to the tips. Todzha was also inhabited by Enallagma c. cyathigerum with a variably melanized abdomen, while in the Central Tuvinian and Ubsu-Nur depressions, E. c. risi occurred. In Turan and the Upper Kaa-Khem basin, intergradation between both taxa took place. In Todzha, Somatochlora exuberata and S. metallica abocanica were sympatric without intermediate forms and with habitat segregation, thus proving their status as separate species. Todzha was also inhabited by Ophiogomphus obscurus while the rest of Tuva harboured O. spinicornis.
