( Figs. 4A , 8A–C , 11D, 11E , 16A, 16B , 32 ) Diagnosis. This species is most similar to L . forcipula sp. nov. in having the pleura with a brown, longitudinal stripe above ( Figs. 7F , 8C ), the wing entirely hyaline ( Figs. 3E , 4A ), the colour patterns of abdominal tergites in females ( Figs. 10H , 11E ), and the shape and pubescence of epandrium, cercus, and surstylus ( Figs. 28A , 32A ), but can be distinguished from the latter in having the postocellar distinct ( Fig. 8A ); aedeagus straight, ventrolaterally with a long, apicodorsally acute process ( Fig. 32D ).
