Remarks.

The specimens examined from Baishih River drainage agrees with the description of Sperchon cornutoides Lundblad, 1941, a species known only from Java ( Lundblad 1936, 1971). This species closely resembles to Sperchon cornutus K. Viets, 1935, which can be easily distinguished by the claws bearing two clawlets instead of a claw with one clawlet in Sperchon cornutoides . Sperchon xiaoqikongensis Zhang & Jin, 2012, a species recently described from mainland China (Guizhou Province, Zhang et al. 2012) resemble the both aforementioned species due to shape of palp and capitulum. According to the original description ( Zhang et al. 2012) this species differs from Sperchon cornutoides in the absence of muscle attachment plates, shorter peg-like seta on P-2 ventral projection and the presence of peg-like setae on P-2 and P-3 (as shown by figure of Zhang et al. 2012, Fig. 18). It is possible, especially in the case of weakly sclerotized specimens or due the clearing treatment with lactic acid, that muscle attachment plates could easily have been unobserved. The taxonomic state and relationships of this species should be investigated with further specimens from the type area.
