and curving onto lateral margin of acropodite, continuing to terminal 

 opening. 



Male paratypes — Except for minor variation in the length, degree 

 of bend, and broadness of the tip, the male paratypes agree with the 

 holotype. 



Female paratype — Length, 28.1 mm, maximum width 5.1 mm, 

 W/L ratio 18.1%, D/W ratio 74.5%. Agreeing essentially with males 

 in somatic features except paranota more strongly declined creating 

 appearance of more highly arched body. Cyphopodal aperture very 

 broad, sides and caudal margin elevated above metazonal surface, 

 latter rising to peak in midline. Cyphopods in situ lying transversely 

 in aperture, common surface visible in opening. Valves (Fig. 67) 

 moderately large, subequal, without distinct lobes, moderately hirsute, 

 situated nearly entirely on receptacle, nearly completely enveloped 

 by latter. Receptacle large, alate, situated to medial side but nearly 

 directly beneath (dorsal to) valves, extending nearly completely up 

 anterior side of latter, caudal "wing" shorter, with numerous long 

 hairs arising from ventral margin. Operculum relatively large, closely 

 appressed to lateral sides of valves. 



Variation — Aside from differences in the length and apical 

 configuration of the prefemoral process, the nontypical males agree 

 closely with the holotype. 



Ecology — Unknown. 



Distribution — The adjacent corners of southwestern Oregon and 

 northwestern California, an area of about 78 mi (125 km) east/west 

 and 59 mi (94 km) north/south. Specimens were examined as follows: 



OREGON: Curry Co., 1 mi (1.6 km) N Gold Beach, on opposite 

 bank of Rogue R., 2M, 30 January 1967, A. Jung (UCD). Jackson 

 Co., Shady Cove, M, 28 March 1972, J. Schuh (FSCA); 10 mi (16 

 km) E, 6 mi (9.6 km) N Gold Hill, along OR Hwy. 234, M, 22 

 January 1972, E. M. Benedict (WAS); and 10 mi (16 km) NW Central 

 Point, along OR hwy. 234, M, 22 January 1972, E. M. Benedict (WAS). 



CALIFORNIA: Del Norte Co., 1 mi (11.2 km) NE Gasquet, 

 Patrick Cr. Cpgd. along US hwy. 199, 28M, 14F, 3 juvs., 22 December 

 1977, and 3M, 3F, 21 December 1979, A. K. Johnson (NMNH, NCSM)

Remarks — Selenocheir directa bridges the anatomical gaps between 

 the Chonaphini and the Harpaphini, and future workers may conclude 

 that this necessitates synonymizing the tribes. The coxa in S. directa 

 is larger in comparison to the telopodal elements than in any of the 

 congeners or any other chonaphines, and the acropodite is directed
