The L. mannengi is simply referring to the close relative to the species of L. elegans found in the western Atlantic.

[6] In the genus Latreillia, the last pair of legs are distinctly longer than half of the carapace, with feather-like hairs running down in rows.

[9] They have been reported at a depth of 35–474 m.[2] The family Latreilliidae is generally found on soft bottoms in tropical and sub-temperate waters.

[12] Interesting findings of gravid female L.elegans around January, March to July, and September, may suggest that this species breeds seasonally.

[13] Despite not having their ecological role clearly stated, it is likely that, like most other crabs, L. elegans have a significance in the food web on multiple levels.

At any stage of their life cycle, they may serve as prey for larger invertebrates and vertebrates or as predators and competition to smaller marine organisms.

[15] This potential relationship provides some insight into the L. elegans role in promoting biodiversity in soft bottom environments in tropical waters.
