Description:
Female: The female has a robust and compact body, with an oval cephalothorax much wider than the abdomen. The prosome consists of five segments, while the urosome comprises four segments. The genital segment is long, narrow, and the largest, approximately equal in length to the succeeding three segments of the urosome. The caudal rami are symmetrical, nearly three times as long as they are wide, with a bare inner margin. The furcal rami are as long as the last two abdominal segments. The antennule is 17-segmented, reaching slightly beyond the metasoma, with the last two segments longer than the previous three and the last segment featuring a smooth hyaline membrane. The terminal segment of the fifth leg bears an inner spine at the apical or subapical position. The inner terminal spine of the endopod of the fourth leg is longer than the outer terminal spine but shorter than the terminal segments. Length: 0.80-1.50 mm. The life cycle primarily comprises six different naupliar and five copepodid stages. External segmentations are absent in newly hatched nauplius larvae, but significant changes occur during the molt to the copepodid stage, closely resembling the adult form.
