[3] The youngest records of the species date to the end of the Early Pleistocene approximately 846,000 ± 57,000 years ago in the Iberian Peninsula.

[4] The species Asoriculus maghrebiensis is known from the Pliocene-Pleistocene boundary (c. 2.5 million years ago) of Morocco in North Africa, making it the only known member of Soricinae to have been native to the African continent.

[8] The Asoriculus species A. corsicanus and A. similis were formerly included in Nesiotites in its original circumscription, though they are usually no longer treated as part of the genus.

The insular species of Asoriculus are substantially larger than A. gibberodon and most other species of Nectogalini, with A. burgioi estimated to weigh 27.54 grams (0.971 oz) and A. similis 23.68 grams (0.835 oz), which has been cited as an example of island gigantism.
