ABSTRACT: The first case of an abnormality in the development of the male palp in Dictynidae is reported, based on a specimen collected in Northeastern Siberia. Both palps of this specimen exhibit an abnormality in the conductor, with the shape differing between each palp. This marks the first occurrence of a malformed conductor in spiders.
