transverse sulcus not deep, little angular and briefly produced 

 behind.

Male: Third dorsal segment not twice as long as the preceding 

 one, fourth nearly equal to the third ; of the ventral ones the fourth 

 is hardly sinuate at apex, the fifth deeply foveate in the middle, the

 and obsoletely sinuate laterally, seventh large, triangular, obtusely 

 carinate at apex ; metasternum at times inconspicuously impressed.
