Celaenopsidae Berlese, 1892 



Figure 95 



Diagnosis: Celaenopsids are 

 similar to the preceding fami- 

 lies but their epigynial plate is 

 obliterated by the lateral plates 

 which are fused medially as 

 well as to the ventral plate 

 posteriorly. The metasternal 

 plates are free, large, and rec- 

 tangular in shape so that they 

 appear to be genital valves. 

 The genital opening, however, 

 is posterior to the metasternal 

 plates.
