ResumoExamination of more than 100 individuals of Procarisascensionis revealed a sex ratio of eight females to one male. Sexes can be determined by the presence of genital apertures on the coxal surface of the third pereiopod in females and the fifth pereiopod in males, as is typical in caridean shrimp. No other secondary sexual characteristics were noted. The mature spermatozoan, a typical "inverted umbrella" consisting of a cell body, cap, and spike, is described and compared to those of other shrimp taxa. A single female was discovered in the laboratory carrying approximately 60 bright orange eggs (diameter 0.83-0.93 mm) on the endopods of the pleopods. These observations confirm the placement of the Procarididea in the suborder Pleocyemata (infraorder Caridea).
