Male hypopygium with tlic l)lackenc(l ])lcural appendage 

 M'ith a conspicuous black spike at base, the tip with small 

 black spinuhe ; each pleural apjicndagc terminates in an elon- 

 gate, slcndpr. gently curved spine, iinmcdiatcly below which 

 is a p:ile cylindrical lobe terminating in a seta; this seems 

 to be a single complex appendage rather than two approxi- 

 mated a])pendages, but this cannot be definitely affirmed 

 without treating the hypopyginm.
