Remarks: This is one of three species of Argia (the two others being A. charalana and A. lobata) described by Navás whose type (s) have apparently been lost. Strong circumstantial evidence has allowed us to associate this name with specimens we include here. The original description of the abdomen describes an oenea -like metallic species with abdominal segments largely blue ("Abdomen in ferne nigrum, superne maxima parte caeruleum vel caruleo-viride. Primum tergitum macula transversa basali nigra, apicem haud attingente; secundum (fig. 12, b) subtotum nigrum, stria brevi dentata laterali caerulea prope apicem; 3-7 annulo apicali nigro (fig. 12, b), antrorsum et sursum in dentem lateralem internum dilatato; 8-9 tota caerulea, 10 basi caeruleum, apice et lateribus nigris; cercis nigris, superioribus arcuatis, apice attenuatis, inferioribus paulo longioribus, apice fortiter in duos lobos vel dentes divisis, superiorem crassiorem et obtusum, inferiorem longiorem et acutum. [Abdomen black below, above for the most part blue or blue-green. First tergite with a black transverse spot, rather not reaching the apex, the second one (fig. 12, b) nearly totally black, near the apex with a short blue lateral stripe having teeth; 3–7 with a black apical ring (fig. 12, b), broadened posteriorly into a lateral inward tooth; 8–9 totally blue, 10 blue at the base, at the apex and the sides black; the cerci black, the superiors arched, attenuated at the extreme end; the inferiors a little longer, at the extreme end strongly divided into two lobes or teeth, the superior one stouter (thicker?) and obtuse, the inferior one longer and pointed]. Navás’ description and figures 12a (S10 and appendages) and 12b (tip of S3 only; S2 is apparently erroneous as we have seen no specimens with the maculation depicted in his figure; we suspect that the error may be due to postmortem discoloration) match specimens we have seen from the Huallaga River region of Peru and this is the only oenea -like metallic blue species known from that country.
We examined two metallic " holotypes " of an Argia in the BMNH, both labeled by Fraser. The description of one of them (Fraser 1946), Argia cuprea Forma c states that "...segment 7 [is] entirely black.." but this is incorrect; the abdominal pattern matches our Fig. 53. Our illustration of its appendages (Fig. 114) is consistent with other material we consider to represent A. limitata (Fig. 113). The other " holotype ", Argia cuprea Forma d, was not mentioned by Fraser except as " A. cupraurea Calv. forma d" but examination shows that it is also A. limitata.
Differentiation of A. limitata is given under A. philipi.
