| A new species of freshwater Ostracoda Cypris polygoniae collected from El-cola wastewater of the sewage station at Sohag, Upper Egypt was described and identified. Among the specific characters, carapace ornamentation is divided into three areas (Thimble-like depression, polygonal reticulation, Smooth area). The first antenna bears 3 rows of fine hairs pseudochaetae on the first segment, one spine on the third segment and γ seta on the sixth segment. Second antenna has three rod-like processes, two swimming setae and rows of fine pseudochaetae hairs on its segments. Mandibula has number of weak teeth, rod-like processes, rows of fine hairs pseudochaetae and a pair of strong setae with small setules on its different regions. Maxillula has two rows of fine pseudochaetae hairs on the second segment of maxillular palp and two claws with 11 teeth on the endite. There are several numbers of rows of fine pseudochaetae hairs of the three thoracopods. Additionally, there are fan-like setae on the fourth segment and one chelated process on the fifth one of third thoracopod. Furca has two rows of fine spines on each uropodal ramus. | ||||
