Diagnosis. The male palp of L. jangseongensis n. sp. is similar to that of L. gachangensis n. sp. in the femur with many strong spines, the tarsus unbranched retrolaterally, with two spurs at tip and a long proximal prolateral spur but without transverse depression, and the conical embolus, but can be easily distinguished from the latter by the tibial nodule with a spine, the shoehorn­like median sclerite, the triangular retrolateral sclerite with serrated tip, and not having prolateral sclerite ( Fig. 3 E­G).
