Abstract

Caecopilumnus hirsutus Borradaile, 1902 (family Acidopsidae Števčić, 2005; subfamily Raouliinae Števčić, 2005; superfamily Goneplacoidea) is recorded for the first time from the Egyptian Red Sea coast, representing a new addition to the goneplacid fauna of the Red Sea. The examined specimen was identified and described based on its diagnostic morphological features, coloration, habitat preferences, and global geographical distribution. Comparative remarks are provided on distinguishing this species from other congeneric taxa and morphologically similar species previously reported from the Red Sea and Indo-Pacific regions. The findings contribute to the expanding knowledge of the regional biodiversity and distributional range of Caecopilumnus hirsutus.
