Etymology. Latin adjective gramineus (of grass), referring to the habitat (grass clumps).

Diagnosis. Distinguished from other Agobardus by the two pairs of distinct dark patches on the dorsum of the abdomen (Figs 25 – 26) and the wide median septum of the epigynum (Fig. 29).

Description. Male (holotype, UBC-SEM AR00034). Carapace length 1.1 (variation 1.1 – 1.2, n=8); abdomen length 1.1. Chelicera: not elaborate; yellowish with gray pigments. Palp (Figs 27 – 28): tibia and tarsus gray brown, other segments light yellow. Embolus slightly curved. Retrolateral tibial apophysis finger-like. Measurements of legs: I 2.0, II 1.8, III 2.3, IV 2.5. Color in alcohol (Fig. 25): carapace gray brown, darker in eye area, with wide lateral marginal stripes and a central stripe behind fovea composed of white setae; abdomen light yellow, with light brown markings and two pairs of dark patches, the anterior pair smaller than the posterior pair; venter with a few dark brown irregular markings and a big dark brown patch in front of spiracle; legs light brown.

Figures 25–30. Agobardus gramineus sp. nov. 25 male paratype, dorsal view; 26 female paratype, dorsal view; 27 male left palp, ventral view; 28 male left palp, retrolateral view; 29 epigynum, ventral view; 30 cleared epigynum, dorsal view. Scale bars: 25 – 26, 0.5 mm; 27 – 30, 0.1 mm.

Female (paratype, UBC-SEM AR00035). Carapace length 1.3 (variation 1.2 – 1.4, n=18); abdomen length 1.5. Measurements of legs: I 2.5, II 2.2, III 2.8, IV 3.1. Epigynum (Figs 29 – 30): window relatively big, occupying more than half of the epigynal plate; median septum wide, with opening of copulatory duct anterior. Copulatory ducts short, without obvious accessory gland; spermathecae spherical. Color in alcohol (Fig. 26): similar to that of the male, but lacking lateral marginal and distinct central stripes on carapace.

Natural history. Specimens were found in grass clumps in a desert.
