Key to adult males of Regalana :

1. Aedeagus apex with single pair of elongate (LV) processes (Fig. 62)......................... R. prestoi sp. nov. ( Peru)

- Aedeagus apex with three or four pairs of processes (Figs 26, 50): anteromedian (AM), anterolateral (AL), laterodorsal (LD) and/or lateroventral (LV)............................................................................... 2

2. Aedeagus apex with LV bearing additional branches or processes (Fig. 38)........................................ 3

- Aedeagus apex with LV lacking branches or processes (Figs26, 50)............................................. 5

3. Aedeagus shaft with pair of lateral slender elongate processes at mid-length (Fig. 14); apex with LV directed laterally (Fig. 14)............................................................................. R. bobbyi sp. nov. ( Ecuador)

- Aedeagus shaft without paired elongate processes at mid-length (Fig. 3); apex with LV directed ventrally, parallel to shaft in posterior view ( Fig. 2 ).................................................................................. 4

4. Aedeagus shaft with expanded lateral flanges at mid-length (Fig. 38); apex with LD curved and converging in dorsal and posterior views (Figs 38, 39) and LV as long as half of shaft length (Fig. 37)........................ R. ericki sp. nov. ( Peru)

- Aedeagus shaft without expanded lateral flanges at mid-length (Fig. 3); apex with LD widely divergent in posterior view (Fig. 3) and LV shorter than half of shaft length ( Fig. 2 )....................... R. corona DeLong & Freytag, 1975 ( Panama)

5. Aedeagus apex with LV, in lateral view, positioned in same plane as shaft (Fig. 49)................................. 6

- Aedeagus apex with LV, in lateral view, oriented anteriorly or posteriorly to shaft (Figs 25, 73)....................... 7

6. Aedeagus shaft with lateral dentiform projections along apical half (Fig. 50); apex with AL, in dorsal view, with apices abruptly converging (Fig. 51) and LD sharing a common stem with LV; style without serrated ventral margin (Fig. 48)....................................................................................... R. hanki sp. nov. ( Peru)

- Aedeagus shaft without lateral dentiform projections (Fig 96); apex with AL, in dorsal view, completely parallel to eachother (Fig. 97) and LD absent (Fig. 95); style with ventral margin serrated (Fig. 94)............ R. uni sp. nov. ( French Guiana)

7. Aedeagus apex with LD much shorter than AD in dorsal view (Fig. 75) and LV extended anterior to shaftin lateral view (Fig. 73)............................................................................ R. sheilae sp. nov. ( Brazil)

- Aedeagus apex with LD approximately as long as AD in dorsal view (Fig. 27) and LV extended posterior to shaft in lateral view (Fig. 35).................................................................... R. dianae sp. nov. ( Peru)
