Material examined

Type material

1 paratype, IVORY COAST, Niangbo, coll. Remy, ( MRAC 7836 ); 3 paratypes, ANGOLA, 30 km N of Vila-Luso, coll. Barros-Machado, Jan. 1949 ( MRAC 6033 ).

Other material

3 adults and 1 juvenile with 11 pair of legs, CONGO D.R., Shaba, Lubumbashi , 11º40’ S, 027º28’ E, coll. Goffinet G., Dec. 1969 ; 1 adult and 1 juvenile with 10 pairs of legs, CONGO D.R, P.N.A., Secteur Ruwenzori, Kibonbole riv. , coll. Vanschuytbroeck P., 22 Aug. 1955.

Diagnosis

Diagnostic characters are the moderate number of setae on the anterior part of the second tergite, the absence of setae on the triangular projections of the anterior tergites ( Fig. 11D ) and the presence of five striae on the terminal area of the cerci ( Fig. 11F ). Additional diagnostic features of this species in contrast to R. zagnanadina are the narrower head – 1.5 as long as wide ( Fig. 11D ) – and the larger penultimate tergite – 0.8 times as long as the last one ( Fig. 11E ).
