Argia jocosa Hagen in Selys 1865: 408 View in CoL (36 separate), (description of ♂, "Santa-Fe de Bogota, par Lindig. (Coll. Hagen.)"); Calvert 1901; 71 (key); Calvert in Calvert & Hagen 1902: 111 (catalog); Calvert 1909: 120, 143 (key, Colombia); Heckman 2008: 361 (key, listed erroneously from Ecuador); Pérez-Gutiérrez & Palacino-Rodriguez 2011: 212 ( Colombia): De Marmels 2012: 253 (distribution in Venezuela, illustrations and comparison with A. cupraurea View in CoL and A. orichalcea View in CoL ).

Types. LECTOTYPE by present designation, ♂. " St. Fe de Bogota / Lindig 1863", " A. jocosa Hag. View in CoL / an A. cuprea View in CoL var?", "Penis/ drawn [written by C.H. Kennedy]", "Hagen [printed]". MCZ 12194 ( Fig. 128 View FIGURES 128–130 ) . Paralectotype ♂, same locality label. [ MCZ] .

Specimens examined (only those from Ecuador listed). 1 ♂, Sucumbios Prov., Bellavista River, 32 km southeast of Lago Agrio ["A wide river, 3–4 meters across with good flow, bottom stony with some deeper holes, bordered by secondary forest (W-721)"] (0°0'21" S, 76°38'37" W, 285 m), 11 January 2014, David Wagner, William Haber, Fred Morrison leg.

De Marmels (2012) provided a thorough review of this species within Venezuela and cleared up its misidentification with A. cupraurea . Its male is the most variable of all of the metallic red species. The lectotype (Fig. 50) is characterized, as Calvert (1901) noted by "Segments 3–7 black on dorsum, basal half of 3–6 blue, 8–10 blue on dorsum." Most males of this species (including all those known from Venezuela) differ in having S3–5 blue for two-thirds or more of their length (as in Fig. 52). The male from Bellavista River, Ecuador (Fig. 52) has the inferior black on S3–6 thicker than on males from Colombia and Venezuela. Another male from Lloraudo River, Colombia has S3–7 predominantly black (Fig. 51) thus approaching the color pattern of cuprea -like species A. dives and A. philipi . The thoracic dorsum is normally entirely metallic (as in Fig. 20 View FIGURES 19–22 ) but the male from Bellavista River, Ecuador ( Fig. 17 View FIGURES 14–18 ) has a narrow blue antehumeral stripe and another male from Reserva Natural El Rey Zamuro, Colombia has a similar pale antehumeral stripe that is about as wide as the middorsal black stripe. The middorsal and humeral stripe, the latter of which is divided above at its upper third, show no metallic coloration although metallic reflections are present on the prothorax and head. All of these males conform to what we believe to represent A. jocosa as the male appendages and genital ligula (unique for this species) match those of the lectotype ( Fig. 95 View FIGURES 94–97 ). The Bellavista River pair represents a new record for Ecuador. We also examined an additional 296 ♂♂ and 75♀♀ from Colombia and Venezuela for this account.
