Remarks.

This species was described from Venezuela (Dall 1885) and reported from Surinam as early as 1975 (Altena 1975). The studied material represents the first record of the family Strobilopsidae in French Guiana (Gargominy and Fontaine 2015).

In French Guiana, Strobilops morsei is only known from the Mitaraka Mountains between 340 and 600 m a. s. l.

The two COI sequences (same haplotype) are related to some Strobilops labyrinthicus from Canada (p - distance 7.2–8.1 %).
