Abstract: 

The new Triassic species for Bulgaria – Costirhynchopsis vidlicis (Urosevic, 1981) is studied by statistical methods, to determine the external morphology of the shell and by serial sections, for internal shell structure. By comparing description of Costirhynchopsis Dagis, 1977 and Fissirhynchia Pearson, 1977 it is accepted that the two genera are separate taxa, even though they are very close.

С. Бенатов. Costirhynchopsis vidlicis (Urosevic, 1981) – новы брахиоподовый вид для болгарского среднего триаса. Описан новый для болгарского среднего триаса брахиоподовый вид Costirhynchopsis vidlicis (Urosevic, 1981). Использованый: статистичееский метод для охарактеризирования внешней морфологий вида и метод серийных пришлифовок для выяснение внутренного строения рааковин. Сравнение родовых диагноз Costirhynchopsis Dagis, 1977 и Fissirhynchia Pearson, 1977, указывает на самостоятельность двух таксонов, несмотря на большую близость их харакетристик.
