Differs from all other Eviulisoma species, except E. iuloideum and E. lanceolatum, by the obviously
articulated gonopod acropodite. Very similar to E. iuloideum, with which it shares the very large,
subrectangular solenophore, but differs from that species by having a pointed, tapering mesal acropodite
process (map) with a subapical side branch (vs map cylindrical, not tapering and without a side branch),
as well as by having a rounded trapezoid, tritubercuate hypoproct (vs a triangular hypoproct).
