Colimbicola macvourae (Wilson, 1941) 



E sthi op tenon macrourae Wilson, 1941. J. Parasit., 27: 262, figs. 



5-8. 

 Type host: Zenaidura macroura (Linnaeus) — Mourning Dove. 



Normally only 1 species of Columbicola is found upon a single 

 host species. Columbicola maarourae appears to be restricted to the 

 eastern part of the range of Zenaidura macroura, and is apparently 

 replaced in the western part of the host range by Columbicola baculoides 

 (Paine, 1912). This is one of the few examples of geographical distri- 

 bution to be found in the Mallophaga. In almost all other cases 

 mallophagan distribution is the same as host distribution. 



CRASPEDONIRMUS 



Craspedonirmus Thompson, 1940. Ann. Mag. Nat. Hist., (11), 6: 516. 



Type species: Docophorus frontatus Nitzsch, 1866. (A synonym of 

 Docophorus oolymbinus Denny, 1842). 

 Colymbicola Uchida, 1948. Jap. Med. J., 1: 309. 



Type species: Docophorus graviceps Kellogg, 1896. (A synonym of 

 Docophorus colymbinus Denny, 1842). 



Head broad, conical with rounded temples and prominent forehead; 

 dorsal anterior plate shield shaped, concave in front, posteriorly with 

 long acuminate tip; trabeculae small; antennae short, filiform and 

 similar in the 2 sexes; lateral margins of head almost straight; pos- 

 terior margin almost straight. Main feature of the head is its division 

 into 2 by a dorsal line running transversely just posterior to the 

 base of the antennae. Prothorax small; pterothorax larger, but neither 

 as wide as the head at its widest point. Abdomen slightly more than 

 1 1/2 times as long as wide; 4th segment broadest; transverse bands 

 continuous; pleurites strongly pigmented and sclerotized; tergites 

 separated from the pleurites by a narrow clear area, almost rectangular; 

 terminal segments of female bilobed; male genitalia small, parameres 

 hooked at distal end. Members of this genus are parasitic on the order 

 Gaviif ormes .
