Etymology. This species is dedicated to the famous French arachnologist Eugène Simon, who was the first to define the hypocrita -group ( Simon 1893, 1914), and described several species belonging to the group.

Diagnosis. This species belongs to the heeri -complex, along with D. heeri and D. drescoi sp. nov., but can be identified by some differential characters such as the very blunt inferior prong of the RTA ( Fig. 23 View FIGURES 20 – 27. 20 – 23 ), the short and narrowed embolar coil tip ( Fig. 22 View FIGURES 20 – 27. 20 – 23 ), and the egg-shaped to subpentagonal epigynal atrium ( Figs 16 View FIGURES 10 – 19. 10 – 15 , 20 View FIGURES 20 – 27. 20 – 23 ), which is smaller than that of the two others species ( Table 1 View TABLE 1 ).

Description. Male dimensions (paratype): total length 12.86. Carapace 5.45 long, 4.19 wide. Leg I: femur 5.06, patella 2.91, tibia 5.40, metatarsus 4.32, tarsus 2.23, total 19.92. Leg II: femur 4.36, patella 2.47, tibia 3.88, metatarsus 3.30, tarsus 1.93, total 15.94. Leg III: femur 3.93, patella 2.11, tibia 3.06, metatarsus 2.96, tarsus 1.82, total 13.88. Leg IV: femur 4.93, patella 2.40, tibia 4.41, metatarsus 4.46, tarsus 2.11, total 18.31. Leg spination: femora: I, II d11-0; I p0-0(1)-1; III r0-1-1; IV p0-0-1; tibiae: I v1 p(0)-2-0; II v0-2-1p(0); III, IV p1-1-1; III v2-2 (1p)-2, r1-1-1(1-1); IV r1-1-1-1(1-1-1); metatarsi: III p2(1)-2-2, r1(2)-2-2; IV v2-1 p-2. RTA bifid, superior prong short and strongly curved, slightly longer than the blunt inferior prong ( Fig. 23 View FIGURES 20 – 27. 20 – 23 ); median apophysis pointing inwards; embolar coil twice looped, spiralling upwards along one axis, without terminal apophysis, and enlarged before its short, narrowed tip ( Figs 22–23 View FIGURES 20 – 27. 20 – 23 ).

Female dimensions (holotype): total length 14.29. Carapace 5.78 long, 4.48 wide. Leg I: femur 4.48, patella 2.63, tibia 3.81, metatarsus 3.30, tarsus 2.02, total 16.24. Leg II: femur 4.28, patella 2.44, tibia 3.42, metatarsus 3.10, tarsus 1.90, total 15.14. Leg III: femur 4.02, patella 2.23, tibia 2.96, metatarsus 2.83, tarsus 1.73, total 13.77. Leg IV: femur 5.06, patella 2.45, tibia 4.23, metatarsus 4.30, tarsus 2.15, total 18.19. Leg spination: femora: I, II d1-1-0; I p0-0(1)-1; III r0-1-1; IV p0-0-1; tibiae: I v0(1p)-2-0(1p); II v0-2-1p(0); III p1-1-1, v2-2 (1p)-2, r1-1-1(1-1); IV p1-1-1(1-1-1-1), r1-1-1-1(1-1-1); metatarsi: III, IV r1(2)-2-2; III p2(1)-2- 2; IV v2-1 p-2. Atrium small, egg-shaped ( Fig. 20 View FIGURES 20 – 27. 20 – 23 ) to subpentagonal ( Fig. 16 View FIGURES 10 – 19. 10 – 15 ), slightly higher than wide to slightly wider than high (0.28–0.44 wide, 0.33–0.46 high, ratio 0.80–1.14); anterior arch strongly sclerotized, usually curved forwards ( Fig. 16 View FIGURES 10 – 19. 10 – 15 ), but sometimes almost straight ( Fig. 20 View FIGURES 20 – 27. 20 – 23 ); copulatory openings narrow, only visible in posterior view, clearly separated; membranous coils looped more than twice, with internal contour followed by spiral-column shaped coiled ducts ( Figs 17 View FIGURES 10 – 19. 10 – 15 , 21 View FIGURES 20 – 27. 20 – 23 ).
