Type material.

Holotype male: India: Tamil Nadu, Nilgiri Hills, v/1961, P. S. Nathan (CNC).

Diagnosis.

The most distinctive and unique feature of this species is the medially incomplete medial vein. Among the species that lack a medial vein entirely, including Loboscelidia bakeri , Loboscelidia fulgens , Loboscelidia reducta and Loboscelidia guangxiensis , Loboscelidia incompleta can be distinguished by the Rs vein twice as long as R (1.5 × or less in the other species). It does share the fore and midtibial flanges lacking as in Loboscelidia reducta .
