Diagnosis. The length of the forewing is 10–11.5 mm in males. Palaeugoa peregrina differs externally from its two relatives by its markedly larger size and the more intense brownish suffusion in the subterminal area of forewing. The male genital capsule of P. peregrina differs from that of the other members of the species-group by the much longer spines on the ventral part of anellus, the conspicuously angled medial section of the costal margin of the valva forming a medio-dorsal triangular protrusion (in P. aristophanousi and P. ngoko the costal margin is gently rounded) and the robust, curved and densely setose medial saccular process which is considerably shorter and smooth in P. aristophanousi and P. ngoko . The aedeagus of P. peregrina differs from those of P. aristophanousi and P. ngoko by the broadened and spinulose distal section of the dorsal distal crest, whereas that is evenly narrow and smooth in P. aristophanousi and P. ngoko . The vesica of P. peregrina is similar to that of P. aristophanousi , but differs from it by the absence of a subbasal ventral diverticulum, the less elongate medial diverticulum, and the more extensive cluster of cornuti on the ventral diverticulum. The configuration of the vesica of the new species and P. ngoko are conspicuously different, expressed by the different positions of diverticula and the presence of robust cornuti on the dorsal diverticulum in P. ngoko , whereas the dorsal diverticulum is only finely spinulose in P. peregrina .

The female is unknown.

Distribution. The species is hitherto known only from Uganda and Rwanda.
