Remarks
.
Plangia nebulosa
was described by
Karsch (1890)
on the female sex, whose main character is the colour of tegmina with vague dark spots. The subgenital plate of the
holotype
is apically rounded. Later
Griffini (1908)
reported another female and described the unknown male from Mukonje Farm (
Cameroon
), with similar tegmina colours. Most specimens above listed show some vague spots on tegmina, males are lacking the black spot on the stridulatory area and have cerci incurved and black tipped, less stout than those of
P. karschi
. The stridulatory file consists of about 90 regularly spaced teeth.
Distribution
.
P. nebulosa
should cover other than
Cameroon
, also
Central African Republic
,
Togo
,
Côte d’Ivoire
and
Liberia
. It was listed as
Plangia
sp. 2
by Massa
et al
. (2020).
