Cosmopepla Stål, 1867: 525.

Type Species: Cimex carnifex Fabricius, 1798 (= Cosmopepla lintneriana Kirkaldy, 1909), by subsequent designation (Kirkaldy, 1909).

Tribal Placement:

Included Species:
binotata Distant, 1889
coeruleata Montandon, 1893
conspicillaris (Dallas, 1851)
cruciaria Stål, 1872
decorata (Hahn, 1834)
intergressa (Uhler, 1893)
     humboldtensis Bliven, 1955
lintneriana Kirkaldy, 1909
     carnifex (Fabricius, 1798)
     bimaculata Thomas, 1865
uhleri Montandon, 1893

Comments: Cosmopepla was recently revised, including a key to all species, by McDonald (1986).  The most commonly encountered species has been called C. bimaculata by most workers, but its original combination (Pentatoma bimaculata) is preoccupied; the correct name for this common North American species is C. lintneriana.

Key to Species of Cosmopepla (modified from McDonald, 1988)

1      Overall coloration greyish, brownish, or orange-brown with markings in black or orange


-      Overall coloration black or metallic blue-black with yellow, orange, or red markings



2(1)  Reddish brown with a distinct irregular transhumeral orange band (western U.S.)

uhleri Montandon

-       Reddish to grayish brown species with dark punctuations; lacking orange transhumeral band (western U.S.)

intergressa (Uhler)


3(1)   Scutellum with two distinct marginal red spots, near apex of frena on each side (Canada, U.S., Mexico)

lintneriana Kirkaldy

-        Scutellum lacking red spots near apex of frena, tip of scutellum may be thinly margined with yellow or orange


4(3)   Pronotum with yellow transhumeral band bisected by medial longitudinal yellow stripe, forming distinct cross (Colombia, Ecuador)

cruciaria Stål

-        Pronotum usually with yellow to red transhumeral band, but lacking longitudinal medial stripe, not forming cross


5(4)   Transhumeral band irregular, with two small black macules either close together or more widely spaced


-        Transhumeral band arcuate, uniform, lacking black macules




6(5)   The two small black macules in transhumeral band placed relatively close together

binotata Distant

-        The two small black macules in transhumeral band placed relatively far apart (Idaho, Colorado, Utah, Montana, California, Oregon, Washington, Vancouver Island, Baja California)

conspicillaris (Dallas)



7(5)   Frenum not quite one-third length of the scutellum; shape of body broadly oval; male paramere with a distinct apical thumb-like process; female basal plates subtriangular in shape, contiguous mesially (Texas to Colombia)

coeruleata Montandon

-       Frenum reaching almost one-half length of scutellum; body generally longer and more tapering; male paramere lacking apical process; female basal plates more lobate, apical margin expanded posteriorly, mesial margins contiguous only basally (sw. U.S. to Venezuela)

decorata (Hahn)
