Differs from all other Eviulisoma species, except E. articulatum sp. nov. and E. lanceolatum, by the
obviously articulated gonopod acropodite. Very similar to E. articulatum sp. nov., with which it shares
the very large, subrectangular solenophore, but differs from that species by having a cylindrical mesal
acropodite process (map) without a subapical side branch (vs map tapering, with a side branch), as well
as by having a triangular hypoproct (vs a rounded trapezoid, tritubercuate hypoproct)
