This species was described originally from a single female with deformed antennae. This female was collected at Aburi,
Ghana
,
15.xi.1915
, in
Cola
shoots and buds. The
syntypes
of
marshalli
were collected at this same locality,
30.x.1915
, from flowers of
Hibiscus sinensis
. The original specimens of these two species have been re-examined and clearly represent the same species. Hood described
ventralis
from “numerous specimens” in various flowers from
Kamerun
and
Nigeria
(Ibadan).
Pitkin (1978)
selected as
Lectotype
of
ventralis
the female specimen that Hood had labeled as
Holotype
, and this was collected in
Cameroon
,
23 November 1915
, from flowers of monkshood. This specimen lacks metanotal campaniform sensilla and the forewing clavus lacks a discal seta, but on tergite VIII the campaniform sensilla are posterior to the median setae. The first two character states indicate that, based on this
Lectotype
, the species
ventralis
is correctly considered a synonym of
brunneus
. The
paralectotypes
of
ventralis
from
Cameroon
in the USNM are also identifiable as
brunneus
, and of the 24
paralectotypes
of
ventralis
in the USNM from
Nigeria
that are mentioned by
Pitkin (1978)
, 23 are also identifiable as
brunneus
. However, one
paralectotype
from
Nigeria
, collected on
Melia azederach
, is here identified as
revelatus
, based on the two character states indicated in the key above, and a second
paralectotype
with identical data has also been studied (in BMNH) that also represents
revelatus
. In the Senckenberg Museum Frankfurt there are two female and one male
paratypes
of
ventralis
that were collected in
Cameroon
, and these represent
brunneus
.
This species can be distinguished from other members of this genus by means of the characters in the key above, but the position of the paired campaniform sensilla on tergite VIII is not constant even in females, and in males these sensilla are often close to the posterior margin. Specimens of
brunneus
have been examined from the following countries:
Ghana
,
Sierra Leone
,
Ivory Coast
,
Nigeria
,
Cameroon
,
Ethiopia
,
Uganda
,
Congo
,
Angola
, and
South Africa
(in BMNH & SMF);
Netherlands
(in greenhouse) (in SMF);
Puerto Rico
and Peninsular
Malaysia
(in ANIC). This was one of the most common
Thripidae
collected during a recent survey of crop thrips in Peninsular
Malaysia
(
Mound & Azidah, 2009
). Two males have been studied (in ANIC) that were collected on Citrus at Maricao,
Puerto Rico
, “
4.10.07
”, and submitted for identification by Prof. Irma Cabrera.
