Etymology.

The species name is a noun in apposition derived from the Chinese pinyin “sānjiǎo” (triangle) and refers to the distinct triangular shape of the external genitalia.

Diagnosis.

Females of L. sanjiao sp. nov. can be distinguished from other congeners by the distinct triangular form of the external genitalia (Fig. 35B) (vs. the absence of triangular external genitalia in congeners), and a pair of transverse linear spermathecae (Fig. 35A) (vs. the absence of linear spermathecae in congeners).
