Diagnosis.

This species differs from L. wuyiensis by the short and C-shaped basoembolic apophysis with 2 arms in ventral view (BEA, Fig. 12 B, D, F View Figure 12 ) (vs long, hook-shaped with 3 arms, Fig. 14 B, D – F View Figure 14 ), epigyne with an anterior hood (AH, Fig. 13 C View Figure 13 ) (vs with 2 hoods, Fig. 15 C View Figure 15 ), and septum lacking stalk (Fig. 13 C View Figure 13 ) (vs having a stalk, Fig. 15 C View Figure 15 ).
