- N/A
Two new species belonging to the genus Willemia are described: W. bedosae sp. n. and W. christianseni sp. n. Redescriptions of Willemia dubia Christiansen & Bellinger, 1980 and W. similis Mills, 1934 are provided. Willemia vashtia Wray, 1950 is a new synonym of W. similis. These four species and four other of the genus constitute the Willemia anophthalma-group. This group is characterized by one feature not shared by the other species of the genus: the presence of setae a l on abdominal sternum IV. A comparative table and an identification key are given for these eight species, as well as some remarks on their habitats.
