Zhonghui Zhou (GUGC); Paratypes: 2♂♂ 4 ♀♀, same data as holotype. Remarks. The new species is similar to L. flavipuncatus Li & Song, 2008, but can be distinguished from the latter by the pale dorsal part of the frontoclypeus and the short and robust aedeagus with a pair of furcate processes arising from the ventral margin near the base. Etymology. The species name is derived from the Latin word “ furcatus ”, referring to the aedeagal shaft with a pair of furcate processes.
