Allothrissops mesogaster

Allothrissops mesogaster (Agassiz, 1834) Note. Agassiz (1834) erected the nominal species Thrissops mesogaster with a brief description indicating its distribution in the Solnhofen limestones but without reference or illustration to a particular specimen. The first reviewer of this taxon, Nybelin (1964) refer the species to the genus Allothrissops and fixed the specimen NHMUK PV P. 3679 as its lectotype. Further specimens probably belonging to the type series of Allothrissops mesogaster are recognised in Ebert et al. (2022).
