Differential diagnosis. The new species from the Canary Island La Gomera belongs to the subgenus Origoacalles. It is, from a morphological and genetic perspective, closely related to Acalles pilula Wollaston, 1864 and should be compared with species from La Palma (type locality) and El Hierro. Acalles pilula also occurs very rarely in the north of Tenerife (digit 43), but is not identical with Acalles pilula var. seminulum Wollaston, 1864 here, which was described also from Tenerife (designation of lectotype see Stüben 2000c, page 84-85). This name is a junior synonym of Acalles globulipennis Wollaston, 1854 , a species from Tenerife, Gran Canaria and Madeira (digit 42), which prefers the transition zone between laurel forest and thermophilic brushwood, and can also be found in the low-lying areas near the north coast of Portugal (own records, Stüben, Behne & Bahr 2003).
