| DESCRIPTION |

Size: Similar to the
German cockroach (Blattella
germanica). Male body length is 13-14.5 mm long.
Females are 11-12
mm. Color: Adults are generally dark brown with a
band of pale brown
at the base of the wings and another band of pale brown a third of the distance
from the base, giving adults a "banded" appearance. Abdomens of female
are much broader and rounder posteriorly than the male's. Wings: Male
wings
cover the abdomen
completely. They are
dark brown at the base,
becoming increasingly lighter posteriorly.
Female
wings are short, reddish brown to very dark brown, and never cover the
entire abdomen.
Female wings and bodies
are much darker than those of the male. In both sexes, the
lateral margin of the anterior portion
of the wing is translucent. Pronotum: In both sexes, the
lateral margins of the
pronotum are translucent. Ventrum: Ventral body surfaces and
legs of the male and the legs of the female are light strawcolored.
Nymphs are dark brown, with a contrasting pale brown margin on the
thorax. The meso- and metathorax are pale brown, and the abdomen has a broad,
pale area. The dark and pale areas of the nymphs are in
striking contrast, and easily identify this
species.
