Propallene species indeterminate

( Fig. 2-h )

Material examined Juvenile (TIO908XM2901), Xiamen, China, 23.55°N 117.27°E, 11 m depth, Oct. 2007 .

Remarks The juvenile, with simple ovigers and without genital pores, was difficult to identify. The chelifores were similar to Propallene sp. with four teeth on movable finger and three teeth on immovable finger, but with six sole spines and one long simple spine basally present on the almost straight propodus ( Fig. 2-h ). Although morphologic changes occur during development, due to the distance between these two specimens and the lack of other strong evidence, it is more reasonable to classify this juvenile as another indeterminate species temporarily.
