Exocora Millidge, 1991 

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 1View FIGURE 1 A–C; 2 B; 3 A, 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 1View FIGURE 1 D, E; 2 D, E; 15 A; 16 A).

Carapace orange to yellowish, with two dorsolateral dark marking (e.g. Exocora phoenix  Figs 2View FIGURE 2 A, D). Sternum orange to yellowish, with dark margins. Male chelicerae promargin with 2–3 teeth, retromargin with 3–4 teeth, female chelicerae promargin with 3 teeth, retromargin with 4–5 teeth. Abdomen pale brown, with dark marking and white spots. Eyes, projected anteriorly. Ocular area with bristles (e.g. Exocora phoenix  Figs 2View FIGURE 2 B, E; E. proba  in Millidge, 1991: figs 194). Leg formula I-II-IV-III. Legs yellowish, with dark markings on each articles. Tibia I with a thick prolateral macroseta, thinner in females (e.g. Exocora phoenix  Figs 2View 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 1View FIGURE 1 A–C; 3 A, 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 1View FIGURE 1 D, E; 15 A; 16 A).
