| Abstract |
Mysid specimens collected at Lombok Island, Indonesia were examined and assessed taxonomically. These specimens share morphological characteristics with species of the subgenus Javanisomysis (genus Anisomysis). They are separable from the other four known species of the subgenus by the structure of the fourth male pleopod, and thecondition and pattern of sub-segmentation in the third to eighth thoracopodal carpopropodi of both sexes. The male pleopod is long and reaches the posterior end of the sixth abdominal somite, excluding the apical barbed setae, and the first segment of the pleopod is broader in the proximal one-fourth to one-third. The third to eighth thoracopodal carpopropodi are divided distally into two segments. The population from Lombok Island thus is considered an undescribed species of the subgenus. On the basis of characteristics of the fourth male pleopod, a key to species of the subgenus is provided. |
