Remarks: Argia medullaris is a common species in Ecuador but it has been confused in the past with the more northerly ( Mexico) A. variabilis Selys. The latter species is not treated further here but we recognize both as separate species based on examination of type material. Males of Argia medullaris and A. variabilis Selys are unique in possessing a largely pale coloration on the thorax, dorsum of abdomen, and a continuous black inferior stripe along S3–10 ( Fig. 18 View FIGURES 14–18 ). Argia medullaris was described from at least two males from "Bogota, Nouvelle- Grenade [ Colombia], par Lindig (Collect. Hagen, de Selys)". An incomplete male lacking S7–10 is in the MCZ and the other, the lectotype, is in the RBINS ( von Ellenrieder & Garrison 2007) and is illustrated here ( Fig. 115 View FIGURES 115–118 ).

Applying the name A. medullaris to various populations has been challenging. We have examined specimens we believe to represent this species from Honduras, El Salvador, Nicaragua, Costa Rica, Panama, Venezuela, Colombia, and Ecuador based on comparison with the complete syntype A. medullaris lodged in the RBINS ( Fig. 115 View FIGURES 115–118 ). The late L.K. Gloyd recognized at least three (and possibly more) phenotypes (these given various letters including sp. D [= angustana], T [= columbiana ] and Te [from Ecuador]) from material primarily from Colombia and Ecuador and it is obvious from her notes that she believed the three (and possibly other populations from Central America) to represent distinct species. She recognized what she thought were differing ratios between the width of the torus and length of the distal margin of the cercus. Although our early analysis also led us at first to conclude that more than one species was involved, subsequent relaxing and manipulation of the caudal appendages convinced us that A. medullaris comprises a wide-ranging species that varies slightly in cercal morphology in the males and slight differences in the mesostigmal plates of the females. We have been unable to correlate these minor differences to geography. We believe various postmortem positions of the caudal appendages have contributed to differences that are more apparent than real. For example, the elongate cerci can be moved posterodistally so that they appear long and linear posteriorly, or they can be positioned posterolaterally so that the appendages may resemble the cerci of A. variabilis . The external margin of the cercus can also be seen as a decumbent flap when the cercus is directed posteriorly. This flap first led us to believe in a species-specific difference that disappeared when the cercus was relaxed and positioned posterodistally.

The taxonomy of A. medullaris is further complicated by a series of poor descriptions and illustrations of specimens of Argia from Colombia described by Navás. Disposition of these names is as follows:

Argia rectangula Navás, 1920 . This name was applied to a juvenile female in fair condition lacking S5–10 that we have examined. The mesostigmal plates match those of typical A. medullaris (as in Fig. 80 View FIGURES 77–83 ) and show no significant differences in body pattern. Consequently, we treat this name as a junior synonym of A. medullaris . Navás was apparently impressed with the Hw quadrilateral as this was the only illustration ("Regio quadrilateri in ala post.") accompanying the original description.

Argia columbiana Navás, 1924 . This name was applied to a male and female both of which we have examined. The caudal appendages of the male lectotype ( Fig. 117 View FIGURES 115–118 ) show no significant differences from the lectotype of A. medullaris ( Fig. 115 View FIGURES 115–118 ) and neither does body pattern. Consequently, we treat this name as a junior synonym of A. medullaris .

Argia augustana Navás, 1934 . The holotype was relaxed and placed in an envelope and sent to L. K. Gloyd in the 1930's. Examination by Gloyd and us showed it to be a junior synonym of Argia medullaris . Mesostigmal plates of holotype illustrated ( Fig. 80 View FIGURES 77–83 ). Navás' (1934) figure of the dorsal view of S8–10 ( Fig. 135 View FIGURES 131–135 ) is misleading as it shows a pair of isolated pale spots dorsolaterally on S9. However, these spots extend ventrally as is typical for the female of this species (Figs. 63, 64).

Argia charalana Navás, 1924 . We have examined two males and three females from Medina (♂, in UMMZ), Pandi (♂ [ Fig. 116 View FIGURES 115–118 ], ♀, in UMMZ) and Pensilvania (2♀, in UMMZ & MNHN) labeled by Navás as A. charalana Navás, 1924 . The original description of A. charalana includes only a male with the following data: " Colombia: Charalá (Santander), Marzo de 1915". None of the series mentioned above possess data consistent with that given in the original description. Four of the five specimens listed above were later cited by Navás (1935: 33–34 [1–2 separate]) where he described the female and added the following localities: " Colombia: Pensilvania, 1913, 1918; Villavicencio, Septiembre de 1912; Pandi, Agosto de 1911; Medina, Enero de 1918.". The original description and illustration of A. charalana differ from the series later identified above by Navás as A. charalana . Illustrations of the appendages in the original description of A. charalana strongly suggest those of A. fissa Selys (see Garrison & von Ellenrieder 2017 for illustrations). Navás also describes the wings of A. charalana as tinted ("Alae membrana levissime, vix sensibiliter fulvo tincta.....") a character unique to Argia fissa in Colombia. Although the above series of A. charalana examined by Gloyd (unpubl.) and us matches Argia medullaris , we consider Argia charalana , based on the evidence given above, to be a junior synonym of Argia fissa Selys, 1865 .
