Description
Summary:A new species of Erylus from the Aleutian Islands is described. This is the first record of the genus from the Aleutian Islands. The new species differs from all other known species of Erylus in the presence of different types of monaxonic megascleres, ranging from oxeas, strongyles, styles, tylostyles to tylotes, often with unequal ends and irregular modifications of these types. The lack of a secondary category of asters is also unusual for the genus.
