Preantennal region broadly and evenly rounded in front; clypeal 

 suture present. Preantennal region armed with a pair of posteriorly 

 pointing, lateral horn-like processes which arise from the chitinous 

 thickening just behind the clypeal suture; antennae short, 2nd segment 

 longest; temporal lobes large, squarish. Prothorax smaller than 

 pterothorax, with sides strongly divergent posteriorly. Pterothorax 

 short, but very broad with rounded lateral margins. Abdomen elongate- 

 elliptical, widest at 4th and 5th segments. Mallophaga of this genus 

 are parasitic on birds of the order Columbi formes. 



PhysGonnelloides zenaidurae (McGregor, 1917) 



Goniodes zenaiduvae McGregor, 1917. Ent. News, 28: 433, pi. 28, 



figs. 1 and 4. 

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

 Other New England host: 

 Domestic Pigeon. 



The usual host for this species is the Mourning Dove, it being 

 found only occasionally upon the pigeon. Physaonnelloides zenaiduvae 

 has been reported by McGregor (1917) from South Dakota, Peters (1928) 

 Ohio, Peters (1936) from Ohio and Virginia, and Hanson, et al . , (1957) 

 from Illinois. All of the above collections were made from the 

 Mourning Dove. 



Physaonnelloides zenaiduvae is the only species of the genus 

 found in New England, therefore, the genus description will serve for 

 species identification.

 sexes; antennae filiform and similar in both sexes. Antennal band 

 with greatly thickened internal margin sometimes cellulated in ap- 

 pearance; occipital bands and suture present; temple bands thickened
