Abdominal laterotergites covered with short setae, slightly sloping downward and merging with apex of tergum VIII; lateral margins of III – V with abundant long golden setae; IV– VI broader than anterior and posterior segments.Abdominal sterna without carina or comb of setae medially; VII with shiny brown mark medially.

Distribution. Colombia: Meta ( Fig. 23C View FIGURE 23 ).

Comments. Rhagovelia graziae sp. nov. is a relatively small species, with body length ~ 2.75 in the male and ~3.00 in the female. Other species within this size range are R. molanoi sp. nov., R. rosensis , R. santanderi and R. tantilla . Rhagovelia tantilla and R. molanoi sp. nov. can be readily distinguished from the others by the male hind tibia unarmed, without small spines throughout length or apical spur. Rhagovelia graziae sp. nov. can be distinguished from R. rosensis and R. santanderi by the coxae and trochanters yellow (vs. dark brown to black in the other two), male abdominal sterna II–V with a median comb of long golden setae (vs. only with short setae), male abdominal segment VIII large and robust (vs. small), the shape of the paramere ( Fig. 19N View FIGURE 19 ), the lateral margins of female abdomen sinuous (vs. evenly tapering or bowed), and the posterior margin of female abdominal tergum VIII with long setae (vs. without long setae).

Etymology. This species is named in honor of the Brazilian researcher Dr. Jocélia Grazia (Universidade Federal do Rio Grande do Sul), who has made innumerable contributions to the knowledge of Heteroptera , especially Pentatomoidea, from the Neotropics.
