description: Key to males of the genus Sulabanus *
*This diagnostic key is based solely on male morphology because females of most species are unknown.
1. Elytra with a yellow transverse patch on humeral third of elytra; elytra black around scutellum ............. 2
– Elytra concolorous dark brown to black or only slightly lighter at humeri; if humeral area is lighter, coloration is lightest around the scutellum ....................................................................................................... 12
2. Diameter of eyes in lateral view considerably larger than their frontal interocular distance or their interocular distance approximately equaling eye diameter (ratio 0.80–1.00) ........................................................ 3
– Frontal interocular distance larger, 1.20 to 1.60 times the maximum eye diameter in lateral view.......... 6
3. Apex of phallus at most shallowly emarginate; phallus 3.5-4.0 times wider in middle of its length than in the narrowest point in the apical third (Figs. 19, 21) .................................................................................. 4
– Apex of phallus with two slender processes; phallus parallel–sided or at most 1.7 times wider in middle of its length than in the narrowest point in the apical third, (Figs. 43, 49) ..................................................... 5
4. Widened middle part of phallus more steeply narrowed to apex than to base (Fig. 19) ................ S. minor
– The widened middle part of phallus gradually narrowed to both apex and base (Fig. 21)........ S. cordatus
5. Phallus slender in apical third (Fig. 49), interocular distance equaling eye diameter; ventral part of thorax black............................................................................................................................................. S. ocularis
– Phallus robust in apical half (Fig. 43), very slender basally; frontal interocular distance about 0.80 times eye diameter; ventral part of thorax yellow ......................................................................... S. amporiwensis
6. Phallus considerably widened in middle part, 3.0 times wider in middle of its length than in the narrowest point in apical third of its length (Fig. 15) ............................................................................. S. mamasensis
– Phallus robust or slender, but always parallel–sided or gradually narrowed to apex and base, at most 2.0 times wider in middle of its length than in the narrowest point in the apical third of its length (Figs. 27–62) .................................................................................................................................................................... 7
7. Apical part of phallus deeply emarginate, depth of concavity at frontal edge of the apex of phallus at least 0.8 of distance between points of apical processes of phallus (Figs. 39, 45–48) ....................................... 8
– Apical part of phallus simply rounded with straight frontal edge (Fig. 27) or pointed (Fig. 51) or at most very shallowly emarginate at apex, depth of concavity at most one tenth of width of phallus in middle of its length (Fig. 55) ..................................................................................................................................... 10
8. Thorax ventrally yellow; phallus as in Figs. 39–40 ........................................................................ S. major
– Thorax ventrally black; phallus as in Figs. 45–48....................................................................................... 9
9. Apical part of phallus parallel–sided; processes at apex of phallus very slender (Fig. 45) ............ S. robustus
– Apical part of phallus gradually narrowed to apex; processes at apex of phallus robust (Fig. 47) ............... .................................................................................................................................................. S. brancuccii

– Frontal interocular distance 1.30-1.40 times eye diameter; apical part of phallus wide, shallowly emarginate at apex ................................................................................................................................................. 11
11. Phallus robust, narrower at apex (Figs. 27–28) ..................................................................... S. pendolensis
– Phallus slender, apical part widened (Figs. 57–58) ..................................................................... S. gracilis
