Carapace length 5.1 mm, width 4.2 mm, width of cephalic part 2.2 mm. Carapace surface dull carmine-brown, finely shagreen and with a poorly developed longitudinal furrow. Length of the basal chelicere segment 2.8 mm, the same color as the carapace. Sternum, labium, and coxae lighter than carapace, ranging from red-brown (labium, gnathocoxa) to orange-red (coxa IV). Leg color also ranges from red-brown (coxae, hips) to orange-red (metatarsi, tarsi). Legs I and II darker than III and IV. Pedipalps reddish brown. Ratio of anterior-eye diameter to their distance 17:14. Leg spination: coxa and patella are not armed, femur I with 2 closely standing apical fronto-dorsal spines, femora II and III with 1 spine in this spot, femur IV in the basal half with 220.127.116.11.1 (or 18.104.22.168.1) dorsal spines. Tibia and metatarsus I and II unarmed, tibia III with 1.1 anterior, 1.1 posterior and up to 4 ventro-apical and lateral spines, tibia IV with 1 median dorsal spine, 1 anterior and postero-apical spine as well as to 4-5 ventral and lateral spines.
Abdomen length 7.3 mm, width 3.25 mm, cylindrical, gray, but with a reddish tint near the front due to a cover of red and ginger setae.
Carapace length 5.3 mm, width 4.15 mm, width of cephalic part 2.85 mm. Chelicere length 2.5 mm. Abdomen length 10.3-11.3, width 4.6 mm. Distance between the anterior eyes three-quarters of their diameter.Carapace dull carmine-brown and finely shagreen-like. Pits poorly developed, shallow and present on sides an cephalic part. Longitudinal furrow formed by pits on shallow cephalic part, aside from it with two poorly developed longitudinal ridges. Chelicerae colored like carapace, with fine granulation, which is more dense on the dorsal- lateral part and the medial side. Sternum reddish-orange, vermiculated, except the front, which is markedly wrinkled.Leg spination as in the male, but femur II with two closely standing apical fronto-dorsal spines (rather than one as in the male)
Abdomen with no signs of gray brown, red or blond. hairs on the abdomen lighter and smaller.
D. concinna is significantly larger than D. aculeata (carapace length 5.1-5.4 mm vs. 4.5-5.0 mm). The diameter of the front eyes is larger than their distance in D. concinna but comparable in D. aculeata. Both species also differ in leg spination: D. concinna has no spines on coxae and patellaeI-IV; femur I with less antero-apical spines (2.1-2.1.0 vs. 3.2-3.2-3.1) and femur IV with more dorsal spines in basal position (22.214.171.124.1 against 2.1.1). Male copulatory organs also differ.
