Mesothorax with its sternum and pleurae, or at least the 

 latter, not divided into an anterior and posterior portion 

 by the presence of a carina or suture; in short, without 

 a prepectus 2 



Mesothorax with its sternum and its pleurae, or at least the 

 latter, more or less divided into an anterior and posterior 

 portion by the presence of a carina or suture; in other 

 words, with a prepectus as indicated by Snodgrass 6 



Second and third dorsal segments fused as is evidenced by 

 the apparent second segment having two pairs of spiracles 3
