Sinella colorata n. sp. and Coecobrya mulun n. sp., both pigmented and 3+3-eyed, are described from Guangxi Province in southern China. Coecobrya mulun n. sp., is the first 3+3-eyed species in the large genus Coecobrya Yosii, 1956. The two species live in syntopy and are similar in many respects, but easily separated by their mucro, bidentate in Sinella Brook, 1882 and falcate in Coecobrya, the ratio between the length of the non-annulated distal part of the dens and the mucro (3 vs 1.5), and the position of the tooth on inner side of the claw (at 45 vs 65% from base).
