Head longer than wide, never with a complete carina around an- 

 terior margin; marginal carina interrupted laterally. Dorsal prean- 

 tennal suture, when present, originating at distal end of marginal 

 carina. Dorsal clypeal plate usually present and with rounded, 

 flattened, or acuminate posterior margin but never produced into a 

 thickened point posteriorly. Ventral carina always interrupted 

 medially and extended forward and fused to distal end of marginal 

 carina at each side. Temporal lobes slightly expanded; gular plate 

 moderately well developed. Prothorax small, narrow and distinct from 

 pterothorax, the latter with lateral margins divergent and posterior 

 margin prolonged as a median point. Abdomen in both sexes elongate. 

 Abdominal segments IX-X fused and not separated from segment XI by a 

 definite suture. Tergal plates IX-X continuous across the segment and 

 only slightly narrowed medially. Female with edge of vulva set with 

 fine setae; small spine-like setae and a tubercle on ventrolateral 

 edge of segment IX bearing 1-3 long, stout hairs. Male genitalia with 

 mesosome usually shorter than parameres and often a well sclerotized 

 penis, with opening terminal or ventro-terminal , rarely dorso- 

 terminal. Parameres varying in shape but always elongate.
