*159. Ariadne albifascia (Joicey & Talbot, 1921) WL: 26mm. The present forest species is known from Sierra Leone to Angola and Uganda and is now assigned for the first time to Guinea-Bissau, from where the genus was also unknown. Its confirmation in this country gives credibility to its reference from Senegal by Ackery et al. (2005), and questioned by Larsen (2005). The caterpillars feed on Dalechampia and Tragia (Euphorbiaceae). Studied material. Tombali: Mato de Cambeque (PNFC), 10 de Julho, 1♂ (BS 29155). Probable abundance and proposed status. AB: R; CS: I.
