'''''Fenestraspis''''' is an extinct genus of trilobite in the order Phacopida from the Upper Pragian and Lower Emsian.<ref name="Holloway">{{cite journal |author=David J. Holloway & Maria da Gloria Pires de Carvalho |year=2009 |title=The extraordinary trilobite ''Fenestraspis'' (Dalmanitidae, Synphoriinae) from the Lower Devonian of Bolivia |journal=Palaeontology |volume=52 |issue=4 |pages=933–949 |doi=10.1111/j.1475-4983.2009.00878.x|bibcode=2009Palgy..52..933H |doi-access=free }}</ref> ''Fenestraspis'' is unusual because of the development of extensive fenestrae in the posterior part of the body and apparently of the thorax, the presence of upwardly directed spines on the cephalon, thorax and pygidium, and the exceptionally large and highly elevated eyes.<ref name="Holloway"/>

== Distribution == ''F. amauta'' is only known from the Lower and Middle Devonian of Bolivia (upper quarter of the Lower Belen Formation, which approximately coincides with the transition from the Pragian to the Emsian, near Chacoma-Cahuanota and Patacamaya).<ref name="Holloway"/>
