Etymology. The specific epithet is an adjective from the combination of the Latin cordis (heart) and formis (shaped), and refers to the dark heart-like marking on the front face of male chelicerae.

Diagnosis. Resembles Agobardus oviedo in markings, but differs from it by the heart-like marking on the front face of the male chelicerae (Fig. 12), the non-modified male chelicera, and the spermathecae which are further away from each other (Fig. 20). It resembles A. gramineus in color pattern and markings, but differs from that species by the narrower median septum of the epigynum (Fig. 19) and the wider embolic disc of the male palp (Fig. 17).

Description. Male (holotype, UBC-SEM AR00032). Carapace length 1.3 (variation 1.3 – 1.4, n=2); abdomen length 1.2. Chelicera: dark; proximal part covered with yellow scales; not elaborate. Palp (Figs 17 – 18): light yellow. Embolus curved for less than half a circle. Retrolateral tibial apophysis finger-like. Measurements of legs: I 2.9, II 2.8, III 3.4, IV 3.6. Color in alcohol (Fig. 15): carapace red brown, covered with orange scales, with margins light yellow brown and a light yellow brown stripe behind fovea; abdomen light yellow, with gray brown patches and markings and many light colored speckles; tibiae, metatarsi and tarsi of legs brownish; other segments light yellow.

Figures 15–20. Agobardus cordiformis sp. nov. 15 male holotype, dorsal view; 16 female paratype, dorsal view; 17 male left palp, ventral view; 18 male left palp, retrolateral view; 19 epigynum, ventral view; 20 cleared epigynum, dorsal view. Scale bars: 15 – 16, 0.5 mm; 17 – 20, 0.1 mm.

Female (paratype, UBC-SEM AR00033). Carapace length 1.6; abdomen length 1.5. Measurements of legs: I 3.6, II 3.4, III 4.3, IV 4.5. Epigynum (Figs 19 – 20): window occupying about half of the epigynal plate, median septum narrow. Copulatory ducts short, without obvious accessory gland; spermathecae oval and apart from each other. Color in alcohol (Fig. 16): similar to that of the male except markings on abdomen darker.

Natural history. Specimens were found on rocks in a desert.
