Distribution. Costa Rica, Ecuador, Venezuela.

Remarks. This species was the most common mesembrinellid collected in the Zurquí de Moravia area of San José Province, Costa Rica. Five specimens ( TLW 301–305) were barcoded and formed a distinct cluster ( Fig. 488 View FIGURE 488 ). This species is closely related to L. patriciae   , which is found in Colombia ( Marinho et al. 2017); barcodes show that there is 3.48% genetic difference between the two species.

Etymology. The species name fusconitida   is a combination of the Latin fusco (brown) and nitida (shining), which in combination describe the body color of this species.
