REMARKS

Both the antennula and the scale-setae ( Fig. 2P, Q ) serve to differentiate Trichorhina kribensis from the previous species. This species was known from Cameroon ( Schmalfuss & Ferrara 1982; Ferrara & Schmalfuss 1983) and Equatorial Guinea ( Cifuentes 2021). It is recorded for the first time for São Tomé.
