The Chonaphini 165 



In August 1991 I visited Glacier National Park and searched for 

 M. elrodi at lower elevations on the west side of the Park, near Apgar, 

 McDonald Lake, and the cedar grove near Avalanche Campground. 

 As with Loomis and Schmitt (1971), I did not encounter M. elrodi in 

 these areas or in regions outside the Park near Whitefish, Columbia 

 Falls, and Hungry Horse Reservoir. The species therefore seems to be 

 absent from areas north/northeast of Flathead Lake. 



Montaphe elrodi is the dominant species in the eastward xystodesmid 

 faunal extension into western Montana. Extremely abundant between 

 eastern Washington and Flathead Lake, M. elrodi is now known from 

 about 3 mi (4.8 km) south of the International Border near Porthill, 

 Boundary County, Idaho, and should therefore be expected near Creston, 

 British Columbia, only about 7 mi (11.2 km) north of Porthill. Records 

 from Metaline Falls, Pend Oreille County, and Evans, Stevens County, 

 Washington, are only about 10 and 20 mi (16 and 32 km) south of the 

 border and suggest the occurrence of M. elrodi near Walneta and 

 Nelway, British Columbia. It may also occur near Rossland and Trail, 

 although they are just west of the Columbia River, which may constitute 

 a distributional barrier. When collected, M. elrodi will represent a 

 new genus and species for Canada.

Type specimens — Male holotype and 13 male, 6 female, and 1 

 juvenile paratypes (UWBM) collected by R. Crawford, K. Dorweiler, 

 and J. P. Pelham, 27 April 1991, in Tichenal Canyon, 7.5 mi (12.0 

 km) south, 1.5 mi (2.4 km) east of Waterville, (47.540°N, 120.035°W), 

 Douglas County, Washington. One male and one female paratypes 

 deposited in the NCSM. 



Diagnosis — Prefemoral process short, expanding distad to irregular, 

 deeply divided, bi-lobed termination within curvature of acropodite; 

 latter expanding basically with thickened medial margin and spiniform 

 lateral projection, narrowing thereafter, becoming subacicular apically. 



Color in life — Paranota rust-colored, metaterga black with broad, 

 rust-colored bands along caudal metatergal margins. 



Holotype — Length 23.6 mm, maximum width 4.1 mm, W/L ratio 

 17.4%, D/W ratio 78.0%. 



Somatic features agreeing with those of M. elrodi, with following 

 exceptions: 



Epicranial suture distinct, accentuated by narrow black line. Width 

 across genal apices 2.6 mm, interantennal isthmus 0.9 mm. Relative 

 lengths of antennomeres 2>3>6>4>5>1>7. Genae with distinct central
