This species belongs to the group containing species like forcipata 

 de Meijere, familiaris Osten Sacken, etc., forms that run very close 

 to certain species of Dicranomyia. 



L. familiaris Osten Sacken ^ has the radial sector almost straight, 

 about twice the length of the deflection of R4+5; cell 1st M^ long, as 

 long as Cu^ bej^ond the end of cell 1st M^; cross- veins seamed with 

 brown. L. forcipata de Meijere ^ has the basal deflection of Ri+^ 

 much longer than the cross-vein r-m; basal deflection of Cu^ near 

 the fork of J/; dark markings on the wings sparse, etc.
