Paragnetina transoxanica (Klapálek, 1921)

Some of the syntypes of its junior synonym, Caucasoperla spinulifera Zhiltzova, 1967 were collected in Azerbaijan: one female in Kəlbəcər-Laçın (Zabux), and one female in Yuxarı-Qarabağ region (Həsənqaya). Esera caucasica Navás, 1931, a nomen dubium, may also be a synonym of this species (Zhiltzova 1967), since it was collected at one of the original localities of C. spinulifera (Georgia, Borjomi). Its single specimen, the female holotype, should be in the Museum of Natural History Paris (MNHP) but seems to be lost (Aubert 1952, 1956). Paragnetina transoxanica was described from Kazakhstan, known from all the Caucasian countries, as well from Eastern Anatolia (Darilmaz et al. 2016).
