Remarks. We did not have the opportunity to examine the syntype specimens of D. heeri described and illustrated by Pavesi (1873) from Ticino ( Switzerland). Examination of numerous specimens collected from several parts of the Alps allow us to consider the presence of at least three, perhaps four (see Remarks under D. drescoi sp. nov.), very similar morphospecies, which can agree at first sight with the illustrations of Pavesi (see also figures of D. drescoi sp. nov., D. aff. drescoi and D. simoni sp. nov.). One of these morphospecies, represented by the specimens collected in Allgäu (illustrated by Wiehle 1967) and in Graubünden Canton, corresponds better with the descriptions and illustrations of Pavesi. We decide here that these specimens belong to D. heeri sensu Pavesi.
Material examined. SWITZERLAND. No specific locality: 1 Ƥ, Nicholson, O. P.-Cambridge collection ( HECO B. 236); 1 Ƥ, 1899, R. J. Pickard-Cambridge, O. P.-Cambridge collection ( HECO B. 236); 1 Ƥ and 1 immature 3, 1906, R. J. Pickard-Cambridge, O. P.-Cambridge collection ( HECO B. 236). Graubünden Canton: 1 Ƥ, 1907, R. Lessert, Simon collection n° 23822 ( MNHN AR 9166). AUSTRIA. Tyrol: Sölden, 1 Ƥ, A. W. Pickard-Cambridge, O. P.-Cambridge collection ( HECO B. 235). GERMANY. Allgäu: 2 Ƥ and 1 3, 2000 –2100 m, Aug. 11–13, 1965, Harms, det. Wiehle ( SMF 22517/13).
Diagnosis. D. heeri can be associated with D. drescoi sp. nov. and D. simoni sp. nov. in a complex of species characterised by the presence of 3 or 4 retrolateral spines on tibiae IV, a large embolar coil looped around twice and spiralling upwards along only one axis ( Figs 12 View FIGURES 10 – 19. 10 – 15 , 22, 26 View FIGURES 20 – 27. 20 – 23 ), and a spiral-column shaped coiled duct, following internal contour of the membranous coil ( Figs 11, 15, 17, 19 View FIGURES 10 – 19. 10 – 15 , 21, 25 View FIGURES 20 – 27. 20 – 23 ). However, D. heeri can be distinguished from these by the shape of the RTA, almost symmetric, with an inferior prong greatly sharpened and as long as the superior prong ( Fig. 13 View FIGURES 10 – 19. 10 – 15 ), the blunt tip of the embolar coil ( Figs 12–13 View FIGURES 10 – 19. 10 – 15 ), and the distal part of the membranous coils, extending and projecting forwards ( Figs 11, 15 View FIGURES 10 – 19. 10 – 15 ).

RTA bifid, superior prong short and strongly curved; inferior prong sharp and as long as superior branch, both almost symmetric ( Fig. 13 View FIGURES 10 – 19. 10 – 15 ); median apophysis pointing inwards; embolar coil looped almost twice, spiralling upwards along one axis, without terminal apophysis and blunt at its tip ( Figs 12–13 View FIGURES 10 – 19. 10 – 15 ).
Female dimensions (SMF 22517/13): total length 10.45–11.36. Carapace 4.95–5.14 long, 3.81–3.86 wide. Leg I: femur 3.95–4.03, patella 2.24–2.27, tibia 3.29–3.29, metatarsus 3.03–3.19, tarsus 1.84–1.90, total 14.46–14.57. Leg II: femur 3.74–3.76, patella 2.14–2.22, tibia 2.93–3.02, metatarsus 2.79–2.79, tarsus 1.74–1.79, total 13.45–13.47. Leg III: femur 3.50–3.50, patella 1.86–2.00, tibia 2.64–2.65, metatarsus 2.72–2.72, tarsus 1.67–1.74, total 12.46–12.54. Leg IV: femur 4.50–4.55, patella 2.06–2.15, tibia 3.86–3.87, metatarsus 3.99–4.07, tarsus 1.99–2.06, total 16.48–16.62.
