The female of Meo. cordata sp. nov. can be distinguished from all congeners by: (1) the diameter of atrium, main part of copulatory ducts and spermathecae almost equal; and (2) copulatory ducts heart shaped. Description. Female: total length 3.19; carapace length 0.85, width 1.09; opisthosoma length 2.33, width 2.21; eye diameters: AME 0.07, ALE 0.09, PME 0.11, PLE 0.11; eye interdistances: AME – AME 0.10, ALE – AME 0.01, PME – PME 0.07, PLE – PME 0.03, AME – PME 0.05, ALE – PLE 0.00; leg measurements: I 7.52 (2.67, 0.35, 1.35, 2.51, 0.64), II 4.34 (1.45, 0.27, 0.79, 1.35, 0.48), III 2.88 (1.00, 0.24, 0.57, 0.66, 0.41), IV 5.33 (1.79, 0.34, 1.02, 1.70, 0.48). Leg formula 1423. Epigyne (Fig. 5 A, B): epigyne posteriorly with a rounded atrium. Main part of copulatory ducts almost as wide as atrium, heart-shaped, coiled twice; distal part thin. Spermathecae kidney-shaped, medially situated, almost as wide as main part of copulatory ducts. Fertilization ducts arising from posterior part of spermathecae. Colouration in ethanol (Fig. 7 A, E, I): carapace rounded and pale yellow, laterally with reddish-brown markings. Sternum, chelicerae, and labium pale yellow. Legs and palp pale yellow, with black, flattened spines (missing), black markings and reddish-brown spots.
