Type material examined.

Holotype ♂, Cameroon, Jaunde ( Yaoundé), 1953, Coll. C.F. Roewer (SMF 9906852, SMF 13664: microscopic slide, left palp).

Diagnosis.

Mistaria jaundea comb. nov. and M. nairobii have the retrolateral tibial apophysis to lateral tibial apophysis ratio as 3:1 (see fig. 2B in Kioko et al. 2018; Fig. 1B). They can, however, be distinguished by the absence of an embolic outgrowth in M. jaundea comb. nov. (see fig. 2B in Kioko et al. 2018; Fig. 1B). M. jaundea can be separated from M. nyeupenyeusi by body size and coloration which is smaller and black and white in M. nyeupenyeusi (see fig. 6A in Kioko et al. 2018) compared to medium and cream-yellow in M. jaundea comb. nov. (Fig. 12D).

Carapace yellow, four black lateral bands, fovea 1/5 the length of the carapace. Cephalic region brown. Eye sizes and interdistances: AME 0.16, ALE 0.25, PME 0.19, PLE 0.22, AME–AME 0.13, AME–PME 0.25, ALE–PLE 0.09, PME–PME 0.09, PME–PLE 0.13. Chelicerae brown. Labium and endites brown with white apex. Labium 2/3 length of endite. Legs yellow. Leg measurements: I 14.11 (3.53, 4.81, 3.53, 2.24), II 13.15 (3.53, 4.17, 3.21, 2.24), III 12.51 (3.21, 3.85, 3.53, 1.92), IV 15.71 (4.17, 4.49, 4.81, 2.24). Abdomen ovoid, cream-yellow, two black horizontal parallel lines. Spinnerets cream-yellow.

Palp as in Fig. 1 A–C. Cymbium 1.5 long, slender, yellow, tip about 1/3 length of cymbium (Fig. 1B). Cymbium furrow 1/6 length of cymbium. Retrolateral tibial apophysis same length as tibia. Size ratio of retrolateral tibial apophysis to lateral tibial apophysis 3:1. Patella apophysis cone-shaped, same length as tibia, tip brown, proximal end yellow. Anterior edge of sub-tegulum raised at point of attachment to the fulcrum (Fig. 1A). Median apophysis non-sclerotized, curved at distal end (Fig. 1B). Embolus originating centrally, no embolic outgrowth, small non-sclerotized basal membrane (Fig. 1B).

Female unknown.
