Type material examined. Holotype male (MRAC 188.234), 6 male, 6 female and 1 tritonymph paratypes (MRAC 188.234-188.236) from Clytospiza monteiri (Hartlaub) (Passeriformes: Estrildidae), CAMEROON: Centre region, Yaounde, 3°52'N, 11°31'E, December 1955, coll. J. Mouchet.
Non-type material examined. 1 male (MRAC 152.973) from Euschistospiza dybowskii (Oustalet) (Passeriformes: Estrildidae), CAMEROON: Centre region, Yaounde, 3°52'N, 11°31'E, December 1955, coll. J. Mouchet; 1 male (188.238) from Spermestes bicolor (Fraser) (Passeriformes: Estrildidae), CAMEROON: no other data; 1 female (MRAC 188.237) from same host, CAMEROON: no other data.
Hosts and distribution. This species was recorded from Clytospiza monteiri (type host) and Euschistospiza dybowskii in Cameroon (Gaud 1968). Records of one male and female from Spermestes bicolor in the same region represent ecological contaminations (Gaud 1968).
