Özet:
The aim of this study is to contribute to the taxonomy of the family Canthocamptidae and the genus Attheyella Brady, 1880 through a detailed morphological redescription and molecular characterisation of A. (A.) crassa from Turkey. In addition, we review previous descriptions. Specimens were collected from a spring located in the Tut District of Adiyaman, Turkey. We redescribe both sexes of A. (A.) crassa and provide illustrations and SEM images. Also, we present partial sequences of gene 28S rRNA for future studies. Comparison of the previous descriptions and illustrations with the present redescription has revealed that A. (A.) crassa is a species complex.
