Etymology. ‘ Soleil’ is French for the sun, as this species is characteristically yellow in colour. Noun in apposition. Diagnosis. Both sexes distinct and recognised by the orange-yellow carapace decorated with a brown patch centrally on cephalic and thoracic region, abdomen with brown longitudinal median band (Figs 36, 37). Females differ by having the largest eye tubercles of any species, all eyes situated on silver-white tubercles. Female epigyne with wide, curved hood, situated anteriorly (Fig. 81), differ from M. stakesbyi n. sp. that have a narrow hood. Male palp with RTA short and slender, situated close to bulb, tip extending laterally (Fig. 79); VTA slender and small (Fig. 80). Description. Female. Size, measurements (n = 8).

Abdomen. Longoval, with oval scutum. AL: 1.43; AW: 1.05; AI: 1.36. Palp. Bulb large with a well-defined, dark tegulum, slightly tilted to the lateral side (Fig. 79), differs from M. stakesbyi sp. n. whose tegulum is less sclerotized and smaller; VTA slender, slightly longer than RTA (Fig. 80). Natural history. Newly sampled material suggests that individuals occur in secondary- and middle-aged primary rainforests and swamp forests. Canopy fogging indicated that they occur on trees species such as Teclea nobilis, Rinorea beniensis and Cynometra alexandri. Adults were present from January until October. Distribution. Uganda and Kenya (Fig. 125).
