Hyperolius soror ( Chabanaud, 1921)

Soror Reed Frog

Material: One female, NGK-Nimba 0125 ( Fig. 10C ), two males, NGK-Nimba 0126 ( Fig. 10D ), NGK-Nimba 0127 .

Comments: We heard over a dozen H. soror males calling during the rainy season in a dense grassy swamp, edging forest (07°32.993’N, 008°24.753’W; 425 m asl).

However, only one female and two males were caught there. The species is sexually dimorphic. The female (25.1 mm SUL) had a light green back, with diffuse, minute, reddish-brown spots, red lateral markings, a red stripe from snout to tip of eye, bluish-grey iris, and toes and fingers, including webbing, were faintly red with green tips. Its ventral surface was transparent bluish green. In contrast, both males (SUL 19.1 and 21.1 mm) had a golden iris, a dark red canthal stripe, green dorsum with diffuse, minute, reddish-brown spots, light dorsolateral stripes, and green toes and fingers.
