ARDEICOLA 



Ardsicola Clay, 1936. Proc. Zool. Soc. London, 1936: 615. 

 Type species: Esthiopterum ardeae (Linnaeus, 1758). 



Head longer than wide, triangular in shape with rounded anterior 

 margin; dorsal anterior plate well developed with small papillae on the 

 anterior half. Internal carinae well developed; eyes well developed; 

 postantennal area rounded or with margins parallel, posterolateral angle 

 rounded; males with basal segment of antenna expanded, segments II, IV, 

 and V normal, lateral anterior margin of segment III laterally produced. 

 Prothorax wider than long, sides parallel or slightly diverging. Ptero- 

 thorax about as long as wide, lateral margins straight with slight pos- 

 terior divergence, pustulated setae at the posterolateral angles. Ab- 

 domen elongate; tergites I-VII of female separated medially; tergites 

 IV-VII of male entire; spiracles on segments II-VII. Members of this 

 genus have relatively few setae on the abdomen. 



Members of this genus are found on birds of the order Ciconiiformes , 



I was unable to collect members of this genus during the course of 

 this study, therefore, the descriptions were taken from Tuff (1963) and 

 from the original descriptions.
