106 I. AHMAD 



from sides of antenniferous tubercles on to posterior of propleuron. Pronotal disc pale, pos- 

 terior three-quarters with black punctures, black spots on posterior angles present. Legs light 

 brown, tinged black. Hemielytra pale, tinged with black. Abdomen with dorsum and venter 

 red, a median longitudinal black line extending from first to sixth abdominal venter. Posterior 

 margin of seventh abdominal tergum medially convex ; pygophore large, rectangular, with very 

 thin lobes of ninth segment (Text-fig. 342). 



o" genitalia : Claspers usually extending beyond posterior margin of pygophore (Text-fig. 

 342) ; blades very long with truncated apices (Text-fig. 209) ; both dorsal and ventral pairs of 

 thecal appendages present, ventral pair asymmetrical (Text-fig. 344) ; left lateral conjunctival 

 appendage reduced to a spine-like appendage (Text-fig. 223, E) ; frontal conjunctival appendage 

 with two flat sclerotized pieces (Text-fig. 223, A) ; two right lateral conjunctival appendages 

 (Text-fig. 343), second curved in middle like an arch (Text-fig. 223, F) ; membranous appendage 

 with a curved and pointed dorsal appendage, but terminal appendage absent (Text-fig. 343). 



$. Very similar to o* in general appearance and measurement ; posterior margin of seventh 

 abdominal sternum emarginate, with a small triangular projection in middle (Text-fig. 346). 



$ genitalia : First gonocoxae with convex outer margin (Text-fig. 251) ; intervalvular 

 sacs eight in number, three anterior pairs larger (Text-fig. 348) ; spermatheca large, flask-shaped 

 with a thick, smoothly curved neck, median flange and a small coiled tube.

The range of this species seems very restricted to eastern New Guinea (Papua) and 

 the adjacent Solomon Islands. The adults have been collected at most times of the 

 year. 



This species is closest to L. discoidalis Walker but can be easily separated by black 

 median longitudinal line on the first to the sixth abdominal venter, the rostrum never 

 reaches the third coxae and the pygophore (in the <J) is comparatively very large and 

 rectangular. Its asymmetrical ventral thecal appendages, the small spine-like 

 second lateral conjunctival appendage, loss of terminal appendage and the elongated 

 large flask-shaped spermatheca are other diagnostic features.
