There are 5 ovarian stages during the ovarian development cycle: stage I, before puberty molting and with a triangular pleonal
flap, with the ovary mainly include oogonium; stage II, the ovary is milky white and comprised mainly of previtellogenic oocytes and endogenous vitellogenic oocytes; stage III, the ovary is light yellow or tan and comprised primarily of exogenous vitellogenic oocytes and endogenous vitellogenic oocytes; stage IV, the ovary is deep purple and comprised mainly of nearly mature oocytes and exogenous vitellogenic oocytes; and stage V: the ovary is chocolate brown and comprised mainly of mature oocytes.
Third pleonal pleuron unarmed marginally, posterolateral angle subrectangular; fourth and fifth pleura (Figs.
Third pleonal pleuron unarmed marginally, posterolateral angle rounded; fourth and fifth pleura each with blunt or subacute posteroventral angle, without marginal teeth or denticles.
Presumable synapomorphies among species of Chorocaris and Rimicaris are the following: the tendency of a rostral reduction, nonacuminate antennal tooth of the carapace, nonmarginally dentate posterolateral margin of pleura of fourth and fifth pleonal somites, the presence of a distolateral transverse suture on the antennal scale, and the nonacuminate uropodal protopod.
