Type species by original designation, Exocora proba Millidge, 1991 .
Diagnosis: Males of Exocora are distinguished from other Linyphiidae by the shape of the embolic division, which has an elongated lamella characteristica (= suprategular apophysis in Millidge, 1991: 58) extended anteriorly, and by the projecting eyes (e.g. Exocora phoenix Figs 1 View FIGURE 1 A–C; 2B; 3A, B; E. proba and E. pallida in Millidge, 1991: figs 190–194). Females can be distinguished by the following combination of characters: prominent epigynum with single atrium, prominent eyes, and following a color pattern of orange-yellow carapace, with lateral markings, and pale brown abdomen, with dark markings and whitish spots on the surface (e.g. Exocora phoenix Figs 1 View FIGURE 1 D, E; 2D, E; 15A; 16A).

Legs yellowish, with dark markings on each articles. Tibia I with a thick prolateral macroseta, thinner in females (e.g. Exocora phoenix Figs 2 View FIGURE 2 C, F). Dorsal tibial macrosetae 2-2-2-2. TmIV absent. Male palpal tibia without apophysis. Palp with protegulum. Embolus long and filiform (e.g. Exocora phoenix Figs 1 View FIGURE 1 A–C; 3A, B; E. proba and E. pallida in Millidge, 1991: figs 190–193). Females with prominent epigynum and spermathecae rounded or oblong (e.g. Exocora phoenix Figs 1 View FIGURE 1 D, E; 15A; 16A).
