Key to males of Minagrion View in CoL (cercus in mediodorsal view, except when otherwise indicated)

1. Larger species (54−61 mm total length), abdomen 2x longer than Fw length ( Fig. 1d View FIGURE 1 )................. M. mecistogastrum View in CoL

1’. Medium species (31−44 mm total length), abdomen less than 2x the length of Fw (as in Fig. 1b, e View FIGURE 1 )..................... 2

2. Dorsal plate of cercus broad; ventrobasal portion only 1/5 of the cercus length ( Figs. 3 View FIGURE 3 u−x, 8g−h); tubercle digit-like with a rounded apex ( Fig. 2k View FIGURE 2 )......................................................................... M. waltheri View in CoL

2’. Dorsal plate of cercus narrow (as in Fig. 3h, t View FIGURE 3 ); ventrobasal portion at least 1/2 of cercus length (as in Fig. 3t View FIGURE 3 ); tubercle never digit-like or with rounded apex.......................................................................... 3

3. Longitudinal ridge of cercus not entire (i.e. disrupted along its length) forming a basal and an apical ridge, more pronounced on the distal 1/2 ( Fig. 3l View FIGURE 3 ); sclerotized apex of cercus globose with no apparent teeth ( Figs. 3l View FIGURE 3 , 8d View FIGURE 8 ); tubercle quadrangular with a slightly concave apex ( Fig. 2e View FIGURE 2 )................................................................ M. canaanense View in CoL

3’. Longitudinal ridge of cercus entire (i.e., a continuous ridge along its length, as in Fig. 3d, t View FIGURE 3 ); sclerotized apex of cercus not globose, with evident teeth; tubercle not as above............................................................ 4

4. Cercus shorter than S 10 in lateral view, ( Figs. 3 View FIGURE 3 q–t, 8e–f) and with acute sclerotized apex, with one strong tooth ( Figs. 3t View FIGURE 3 , 8e View FIGURE 8 ); tubercle triangular with acute apex ( Fig. 2i View FIGURE 2 )........................................................ M. ribeiroi View in CoL

4’. Cercus subequal in length to S 10 in lateral view, rounded sclerotized apex, with one strong tooth; dorsal portion of cercus broad at basal half, narrowing towards the base, ventrobasal portion roughly quadrangular, reaching 1/2 of cercus ( Figs. 3 View FIGURE 3 a–h, 8a–b); tubercle quadrangular, with the excavated “beak-like” apex ( Fig. 2 View FIGURE 2 a–b); genital ligula with a small inner fold at the flexure in lateral view, a pair of lateral sclerotized processes, and entire apex ( Fig. 4 View FIGURE 4 a–b)............................
