From these can be derived:
Male: Wing length 5.33 mm; VR 1.04 (096). Frontal tubercles 41 µm.
Clypeus slightly narrower than diameter of antennal pedical. Mesonotum with slight tubercle.
Leg ratios: Ant 1.0-1.05; Mid 0.58; Hind 0.65. BR 8.0.
Tergite IX with about 8 setae in a subdivided pale patch. Anal point moderately wide and parallel sided, Superior volsella E-type of Strenzke (1959), closest to fig. i; Inferior volsella just longer than the anal point, to about middle of gonostyle and bending outwards at the end; gonostyle only moderately swollen and narrows noticably over posterior third.
Female: Length 8-9 mm. LR about 1; no beard.
Hypopygium of holotype male (from Sublette 1966)
Pupa, Larva and Cytology: Not known.
Found: Alaska - St Paul Island, Bering Sea (57.18°N, 170.27°W) (Type locality).
Townes (1945) considered C. conformis to be a synonym of C. pilicornis but, in renamimg it, Sublette noted that it differed in significant ways: the anal point is broader, the Superior volsella more conspicuously hooked, the gonostyles more distinctly tapered apically and the ninth tergite with a conspicuous patch of setae, so considered it a new species closely related to C. pilicornis. It would also be closely related to Species 5e, but there is no mention of a pale scutellum.See also C. pilicornis, and C. sp. 5e.[ Return to Index| Go to References ]
