Key to the males of Anacroneuria from northeastern semi-arid region of Brazil
1 Dorsal keel absent..................................................................................... 2
1’ Dorsal keel present.................................................................................... 3
2 (1) Penial armature with pair of large distal vesicles ( Figs. 3B, C, DView FIGURES 3). In lateral view, gonopore sinuous dorsally with a small elevation in median region ( Fig. 3DView FIGURES 3). Forewing length 10–11 mm ..................................... A. calori n. sp.
2’ Penial armature without distal ventral vesicles (see figs. 10–12 in Righi-Cavallaro & Lecci, 2010). In lateral view, gonopore concave dorsally without a small elevation. Forewing length 11.2 mm .................................... A. terere
3 (1’) Forewing length longer than 10 mm ...................................................................... 4
3’ Forewing length 10 mm or less.......................................................................... 5
4 S ternum IX with row of thick bristles in lateral corners. Distal part of the terminal tube wide, rounded, darker region V-shaped ( Fig. 5BView FIGURES 5). Keel almost rounded in lateral view ( Fig. 5CView FIGURES 5). Forewing length 13.5–14 mm ................. A. singela n. sp.
4’ Sternum IX without row of thick bristles in lateral edges. Distal part of the terminal tube narrow and pointed in dorsal/ventral views, keel pointed (sometimes almost round) in lateral view (similar to fig. 4 in Baldin et al., 2013). Forewing length 10–14.5 mm .......................................................................................... A. debilis
5 (3’) Penial armature subparallel in dorsal and ventral view....................................................... 6
5’ Penial armature narrowing gradually to apex (figs. 13–15, 20, 21 in Righi-Cavallaro et al., 2013)..................... 7
6 (5) Penial armature with gonopore slightly narrow in dorsal/ventral views (at shoulders) (see figs. 13–14 in Righi-Cavallaro et al., 2013). In dorsal view, keel form a pair of divergent, narrow ridges, truncate basally. In lateral view, keel forms a basal steep rise that proceeds to the broad rounded apex, shoulders rounded (see fig. 15 in Righi-Cavallaro et al., 2013). Forewing length 7.5–8.6 mm ................................................................................. A. bahiensis
6’ Penial armature with robust gonopore, truncate (see fig. 20 in Righi-Cavallaro et al., 2013). In dorsal view, keel forms a pair of diverging lines joined proximally. In lateral view, base of keel steep, dorsal contour then curves gradually to tip (see fig. 2 1 in Righi-Cavallaro et al., 2013). Forewing length, 8.0 mm long............................................. A. kariri
7 (5’) Penial armature (see figs. 3–4 in Righi-Cavallaro et al., 2013) narrowing gradually to apex, distal end rounded; subapical region more sclerotized. In lateral view, the keel acute; in dorsal view, appearing as a broad “U”. Vesicles absent. Forewing length 8.0– 9.5 mm .......................................................................... A. amargosa
7’ Penial armature (see figs. 7–9 in Righi-Cavallaro et al., 2013) tapering gradually towards the apex, with a small subapical constriction in dorsal view. In lateral view, keel convex, in dorsal view appearing as two parallel lines. Vesicles absent. Forewing length 8.0– 8.9 mm .......................................................................... A. quilombola
