( Fig. 5 )

Diagnosis. This species resembles P. brunnea Cao & Chen, 2009 from India and Sri Lanka in the male terminalia, but can be distinguished by the following characters: thorax yellow, slightly gray on anepimeron; epandrium with dense setae near posterior and ventral margins ( Fig. 5A ); aedeagus bifurcated medially ( Fig. 5C ). In brunnea : epandrium with ca. 10 small setae near anteroventral corner and ca. 15 setae near posterior to ventral margin per side (fig. 17 in Cao & Chen, 2009); aedeagus with pubescence, trefoil-like apically (fig. 19 in Cao & Chen, 2009).

Description. Characters common to L. brunnea are not referred to in the following description. Male and female. Thorax yellow to yellowish brown, with dark patches; katepisternun yellow to dark brown, with 2 rows of setae below katepisternal setae. Scutellum yellow to brown.
