Species 5g. C. sanctipauli, Sublette 1966.

New name for C. conformis Malloch 1923

Adult


Description of C. sanctipauli, including original description as C. conformis, from Sublette (1966).

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.
