Head circumfasciate; clypeal margin flattened or broadly rounded 

 with clypeal angles prominent. Head without ventral sclerotized spine- 

 like processes. Clavi undeveloped, represented by membranous lobes. 

 Temporal angle with lateroventral process bearing a small hair or spine 

 in at least 1 sex, and usually in both. Occipital margin drawn out 

 posteriorly to form an angle bearing a small hair or spine. Antennae 

 may or may not be sexually dimorphic but in males segments IV-V are 

 never modified or greatly reduced. Pterothorax without lateral indi- 

 cation of meso-metathoracic junction and always bearing ventrolaterally 

 a fine hair arising from a pit in the integument. Hairs either present 

 or absent on meso-metasternum; never present on metasternum alone. 

 Abdomen with 1st segment large with free lateral margin. Abdominal 

 segments I-VII with tergal plates widely separated and sternal thicken- 

 ings in form of lateral, never median, plates. Pleurites broad with 

 complex re-entrant heads. Abdominal segment VII with fine lateral hair 

 arising from a pit in the integument. Abdomen of males consisting of 

 9 segments, 8th greatly reduced and appearing as a lateral rudi- 

 ment on each side; genital opening dorsal and bearing long setae on 

 the anterior and posterior margins. Abdomen of females consisting of 

 apparently 8 segments, actually 10. Tergal plate VIII continuous across 

 segment; vulva either terminal or at level of 7th segment and variable 

 in form.

figs. 1-4. 

 Type host: Bonasa wnbellus (Linnaeus) — Ruffed Grouse. 



Female with clypeal margin broadly rounded. Temporal angle with 

 lateroventral process bearing a seta and a short spine. Head wider 

 than long. Prothorax 1/2 as wide as head, with nearly straight sides 

 diverging from front to rear. Pterothorax triangular. Male antenna 

 with 1st segment enlarged, without a process; 3rd produced distally at 

 right angles to the 4th segment. Abdomen more rounded than in female; 

 pleurites each with 3 or 4 long dorsal setae. 



Emerson (1948) reported this species from Montana. Emerson (1951) 

 reported it from New York, Montana and Colorado.

 Type host: Phasianus colchicus Linnaeus — Ring-necked Pheasant. 



This species has no meso-metasternal setae. The sternal plates on 

 abdominal segments undivided; dorsal chaetotaxy of the 1st abdominal 

 segment, 2-8-2. Female with 12 to 15 setae in a concentration at each 

 posterolateral angle of the vulva. 



Geist (1931) has reported this species from Ohio and Emerson (1951) 

 from California, Iowa, Montana, Oregon, British Columbia, and Ontario.
