Diagnosis: The marginal plate is fused to the dorsal plate anteriorly. 

 When dissected the dorsal plate clings to the marginal plate. A large, 

 distinct, posterior dorsal plate is present. Metasternal plates are also 

 present but they are very small at the posterior comers of the epigynial 

 plate.
