Lobellina weinerae sp. n. is the most similar to L. minuta (Lee, 1980) and L. musangensis Yosii, 1976, but differs from them in chaetotaxic details and the number of mandibular teeth. Lobellina pomorskii sp. n. differs from L. perfusionides (Stach, 1965) in chaetotaxic details and the number of tubercles on Abd.V. Yuukianura deharvengi sp. n. is superficially similar to Y. halophila Yosii, 1955, but it differs in the build of the maxilla, the size of eyes and an inner tooth on the claw, and in chaetotaxic details.
