Key to species of the genus Dendarus from Iran and Turkmenistan
(on males = strongly widened protarsomeres 1–4)
1 Posterior angles of pronotum acute, strongly protruding to humeral region of elytra ( Fig. 2D View FIGURE 2 ). Strial punctures large, strongly elongate, sparse, located each in very deep wide impression; interstriae slightly convex ( Fig. 2D View FIGURE 2 ). Mesotarsi strongly widened, mesotarsomeres 2 and 3 weakly transverse; mesotarsomeres 1–3 with full hair brush on sole ( Fig. 2E View FIGURE 2 )....... D. crenulatus
- Posterior angles of pronotum from obtuse to right-angled, sometimes weakly protruding, but not deeply inserted to humeral region of elytra ( Figs 2A View FIGURE 2 , 3A, E View FIGURE 3 , 5A View FIGURE 5 , 6A View FIGURE 6 , 7A View FIGURE 7 ). Strial punctures small or moderate in size, round ( Figs 1A View FIGURE 1 , 2A View FIGURE 2 , 4A View FIGURE 4 , 6A View FIGURE 6 , 7B View FIGURE 7 , 8A, D View FIGURE 8 ), sometimes comparatively strongly impressed, but in this case very sparse (19–22 punctures in one row) ( Figs 3A, E View FIGURE 3 ); interstriae flattened. Mesotarsi narrow or slightly widened, mesotarsomeres longitudinal; only mesotarsomeres 2 and 3 can be with full brush or reduced tuft ( Figs 1E, F View FIGURE 1 , 2B View FIGURE 2 , 4B View FIGURE 4 , 6B View FIGURE 6 , 8B View FIGURE 8 )................................................... 2
2 Body completely matt. Elytral striae with sparse deeply impressed 19–22 round punctures in each row ( Figs 3A, D, E View FIGURE 3 ).............................................................................................. D. leonhardi
- Body more or less shiny. Elytral striae with not impressed or weakly impressed 27–30 round small punctures in each row ( Figs 2A View FIGURE 2 , 4A View FIGURE 4 , 6A View FIGURE 6 , 7B View FIGURE 7 , 8A, D View FIGURE 8 )................................................................................ 3
3 Pronotum and head shiny, and elytra matt ( Fig. 6A View FIGURE 6 ). Puncturation of pronotum uneven: fine and sparse, with round punctures at middle and sharply coarse and dense, elongate, often merged punctures on lateral sides ( Fig. 6A View FIGURE 6 )...... D. transcaspicus
- Dorsal side uniformly, strongly, moderately or weakly shiny ( Figs 1A View FIGURE 1 , 2A View FIGURE 2 , 4A View FIGURE 4 , 8A, D View FIGURE 8 ). Puncturation of pronotum uniform (dense or sparse), with round punctures................................................................... 4
4 Protibiae narrow, 4.3 times as long as wide (at widest level) ( Fig. 9G View FIGURE 9 )............................... D. vagabundus
- Protibiae wide, 3.25–3.6 times as long as wide (at widest level) ( Figs 9A, E View FIGURE 9 )...................................... 5
5 Protibiae with deep and wide notch on inner side and large acute tooth ( Fig. 9A View FIGURE 9 ); protibia much wider at level of this tooth than at apex; mesotarsi with 1 small brush on sole of tarsomere 2 ( Fig. 1E, F View FIGURE 1 ) or additionally with reduced tuft on sole of tarsomere 3; rarely mesotarsomeres without brush or tuft................................................... D. armeniacus
- Protibiae with small notch on inner side and small straight tooth ( Fig. 9E View FIGURE 9 ); protibiae slightly wider at level of tooth than at apex; mesotarsi with full brush on tarsomeres 2 and 3 ( Fig. 4B View FIGURE 4 )...................................... D. matthewsi sp. n.
