Eresus rubrocephalus COI assembly

In our work, we provide a description of the habitus of a species of ladybird spider found in Northern Africa, specifically Morocco, based on microscopic examination of the palpus and genetic delimitation analysis. The cephalothorax and abdomen of the male spider are both covered with carmine red hairs on the dorsal and ventral side as well on the chelicerae. The palpus exhibits several characteristic distinguishing fea-tures, such as the course of the palpus conductor plate, the characteristic U-shaped groove and the uniquely shaped terminal tooth. Both phylogenetic and species delimi-tation analysis supported establishment of the new species Eresus rubrocephalus sp. n.
