FIGURE 4 in A new genus and species of entocytherid ostracod (Ostracoda: Entocytheridae) from the John Day River Basin of Oregon, U. S. A., with a key to genera of the subfamily Entocytherinae

FIGURE 4. Examples of mating behaviors exemplified in this study. A, posteroventral view of an adult male Uncinocythere occidentalis (NCSM 27036) mating with an A-1 female (NCSM 27037) in the process of molting into its adult stage. Note the sclerotized (yellow) appendages of the adult male versus the nonsclerotized (transparent) appendages of the female. B, adult male Aurumcythere tillmani sp. nov (NCSM 27019) engaged in false mating behavior with another adult male A. tillmani sp. nov. (NCSM 27020), both nonsclerotized. C, adult male A. tillmani sp. nov. (NCSM 27047) attempting to mate with an A-3 juvenile (NCSM 27048), both nonsclerotized. D, adult male A. tillmani sp. nov. (NCSM 27028) with its copulatory appendages embedded in the anterior portion of the carapace of an A-1 female (NCSM 27029), both nonsclerotized.

FIGURE 1. Map of the known distribution of Entocythere cambaria based on published records (as compiled in Hart & Hart 1974) and previously uncatalogued specimens in the USNM IZ Collection (denoted by an asterisk, *). Shading of circles is based on identification prior to this study: dark grey represents E. illinoisensis, now synonymized with E. cambaria; light grey represents E. cambaria, and; white represents Entocythere sp.
