Ribautiella zagnanadina Brölemann, 1926

Fig. 11 A-C

Material examined

2 juveniles with 10 and 11 pairs of legs, CAMEROON, Kounden, 05º42’ N, 010º40’ E, Eucalyptus woodland , coll. Lejeune, Jul.-Aug. 1974 ; 3 adults, IVORY COAST, Banco, coll. Remy, 20 Apr. 1950 ( MRAC 7833 ).

Diagnosis

This species is characterised by the presence of many setae on the anterior part of the second tergite ( Fig. 11A ) and the cerci ( Fig. 11B ). Additional diagnostic features to distinguish this species from the other one studied here – Ribautiella schoutedeni – are the shape of the head, 1.2 times as long as wide ( Fig. 11A ), the moderate size of the penultimate tergite, 0.6 times as long as the last one, the straighter posterior margin of the last one ( Fig. 11B ), and the absence of striae on the terminal area of the cerci ( Fig. 11C ).
