Remarks

Differences between this species and L. acutilobata Ledoyer, 1978 are not readily apparent (see Ledoyer 1978: 300 and this paper), but the posterodistal lobes of the bases of pereopods 5–7 are also scarcely lengthened in young specimens, the posterior margin of pereopod 7 is always with the inferior half straight or somewhat concave, ending with a clear-cut corner at about the middle of the posterior margin and the widest point of the basis (vs regularly rounded in L. acutilobata ). In young specimens gnathopod 2 propodus palm is irregularly serrate, and incisions become deeper and wider with age (vs smooth in young specimens and regularly shallowly serrate in adult). This species has been collected among coral ( Ledoyer 1978).

Distribution

Red Sea (present study); Western Indian Ocean: Madagascar, Mauritius ( Ledoyer 1978, 1986).
