Remarks

This species can be distinguished from other species by the following characters: dimples on dorsal shields uniform in size, dorsal body setae long, falciform with marginal spinules, dorsal setae c 1 widely spaced. Most of our specimens have completely fused coxisternal shields, but others collected from the same habitat with deep incision in posterior margin of coxisternal shields as Figure 1 . Coxisternal shields reticulate with punctations, except for central region of posterior coxisternal (metasternal) shield which has only punctations and a few with several striae. Length of body 280–337, width 170–213, distance between setae c 1 – c 1: 77–96.
