description: Key to males of Telosticta   
 1. S10 with a clump of long setae dorsally, interior projection of superior appendage absent........................................ T. tubau   
– S10 without a clump of long setae dorsally, interior projection of superior appendage present.............................................. 2  
2. Lateral processes of posterior pronotal lobe longer than half the distance from their origin to the lower margin of the propleuron (Figs. 3A, D, 9, 17A, B)....................................................... 6  
– Lateral processes of posterior pronotal lobe shorter than half the distance from their origin to the lower margin of the propleuron (Fig. 3B, C, E, F).................................................................. 3

– S8 with at least some blue dorsally, superior appendages with the interior projection better developed but without a clump of long setae originating on and around the projection (Fig. 6B, F)........................................................................................... 5  
 5. Superior appendage with interior projection as in Fig. 6F, in lateral view abruptly down-turned apically at level of dorsal projection (Fig. 7F).................................................. T. serapi   
 – Superior appendage with interior projection as in Fig. 6B, in lateral view only slightly down-turned apically (Fig. 7B)................................................................................... T. dupophila   
 6. Interior projection of superior appendage nearly as long as the distance from the margin of S10 to the base of the projection (Fig. 12D).............................................................. T. paruatia   
– Interior projection of superior appendage much shorter than the distance from the margin of S10 to the base of the projection................................................................................................ 7  
7. Tip of superior appendage with a conspicuous deep cleft or excision in lateral view (e.g., Fig. 13A–E)........................... 8  
– Tip of superior appendage variously shaped but without such a cleft or excision (Figs. 13F, 18C, D), or at most a small notch, difficult to see from most angles (Fig. 7A, C)................... 11  
8. Lower arm of the cleft in end of superior appendage clearly shorter than upper arm in normal lateral view (Fig. 13A, D, E)........................................................................................... 9  
 – Lower arm of the cleft of superior appendage ca same length as upper arm in normal lateral view (Figs. 13B, C)... T. dayak   
 9. Arms of tip of superior appendage protruding interiorly, and continued as prominent ridges above the cleft, forming a deep groove between them, clearly visible in dorsal view (Fig. 12E)..................................................................... T. ulubaram   
– Arms of tip of superior appendage only weakly expanded interiorly, so that only a shallow or no groove is visible in dorsal view (Fig. 12A, C).................................................... 10

– Superior anal appendage appendages with dorsal projection small and inconspicuous..................................................... 13  
 12. Superior appendage conspicuously expanded from ca half length in both dorsal and lateral views (Figs. 12F, 13F), the dorsal projection large and directed dorsally, clearly visible in lateral view (Fig. 12F)................................................. T. longigaster   
 – Superior appendage only expanded in apical ca one quarter to one third (depending upon angle viewed from), the dorsal projection inwardly directed (Fig. 18A), not visible in lateral view (Fig. 18C)............................................ T. belalongensis   
 13. Tip of superior appendage flattened, expanded and strongly folded over on its self to almost form a tube (Fig. 18D)........................................................................................... T. janeus   
– Tip of superior appendage flattened laterally, but not strongly folded................................................................................... 14  
 14. Interior projection of superior appendage placed at the point where the basal part of the appendage contracts (Fig. 6C), labrum only blue narrowly at base, blue markings on S8 and S9 dorsally (Fig. 5C)............................................... T. feronia
