Notes: The adult female of a Neotropical scale insect from Guyana, Laurencella jonmartini n. sp., is described and illustrated with the third-instar female of the possible same species. Each has distinctive morphological features. The adult female possesses circular, convex cribriform cicatrices on the venter of the posterior abdominal segments and dorsal groups of large ampulliform and other setae with spines and pores, all in a symmetrical arrangement, each group named here a setarium, a remarkable characteristic of the species. The third-instar females of possibly the same species also possess setaria but they are of a slightly different structure, each comprising a dense group of short and long spines, each setarium secreting a series of white, stud-like projections in longitudinal rows on the dorsum and margin.
