126 I. AHMAD 



COSMOLEPTUS Stal 



Cosmoleptus Stal, 1873 : 86-87 



Type-species : Lyrnessus limbaticollis Stal by monotypy. 



Body usually robust. Head triangular. Antennae with apices of basal segments slightly 

 thicker. Rostrum long, approaching hind coxae. Pronotal disc trapeziform with black 

 sculpturation, lateral and anterior margins pale, impunctate (Text-fig. 4). Posterior angles 

 without spines. Legs with fore femora armed with ventro-posterior spines (Text-fig. 9). 

 Hemielytra, cuneus with a white spot. 



In (J. posterior margin of seventh abdominal tergum truncated, medially slightly concave 

 (Text-fig. 403) ; pygophore rounded ; claspers with pointed apices (Text-fig. 405) ; aedeagus 

 with dorsal and ventral pairs of thecal appendages, a pair of fused supporting appendages and 

 membranous appendage with usually a terminal appendage (Text-fig. 406) ; frontal conjunc- 

 tival and dorsal appendages wanting. 



In $, posterior margin of seventh abdominal sternum emarginate, with a median fold (Text- 

 fig. 408) ; first gonocoxae large, usually two pairs of intervalvular sacs present (Text-fig. 411). 

 Spermatheca tubular (Text-fig. 407). 



This genus is close to Noliphus but can be separated by the absence of spines on 

 posterior angles of pronotum. Its fore femoral spines are unique.
