Fig. 3 View FIGURE 3 (♂ —App), Fig. 17 View FIGURE 17 (♂ —habitus), Fig. 27 View FIGURE 27 (♀ —habitus), Fig. 37 View FIGURE 37 (A— ♀ S8–S10), Fig. 39 View FIGURE 39 (A— ♀ basal plate), Fig. 40 View FIGURE 40 (C— ♀ pectoral color pattern), Fig. 42 View FIGURE 42 (♂ —live photo).

Etymology: dichrostigma   = dichros, Greek (δίχρως) for two–colored + stigma, Latin for mark, in reference to the bicolored pterostigma, which occurs only in the juvenile.

Diagnostic characters. ♂ —Cercus in lateral view: basal two thirds straight, with medial expansion clearly visible as an inverted triangle with the vertex at the level of the tip of the paraproct, tip of cercus comma–like shaped. Cercus in mediodorsal view: base of cercus without spine, medial expansion of cercus almost twice the width of the base and roughly triangular with a small bump at the apical end, without any spine. Paraproct in lateral view: almost a third of the length of the cercus. Paraproct in dorsal view: with a broad base and finger–like distal end.

♀ —Basal plate: species belonging to basal plate group 1 ( Fig. 38 View FIGURE 38 ), with dorsal side twice the length of ventral side, posterior side with ventral section shorter than the dorsal section ( Fig. 39A View FIGURE 39 ). Pectoral color pattern as Fig. 40C View FIGURE 40 .
