Wasmannia auropunctata
(Roger, 1863)
Fig. 9
First record to
Gambia
.
This invasive ant of Neotropical origin is steadily spreading to the tropical regions, having been recently detected in
Spain
(
ESPADALER
et al
., 2018
), Guandong (
CHEN
et al
., 2022
) and
Taiwan
(
LEE
et al
., 2021
).
Reported from Central Africa and
Sierra Leone
, its presence in this country should be confirmed as its first record dates from 1890; with no additional records in between (
WETTERER, 2013
). Its presence in Central Africa, though, is confirmed and its spreading from
Gabon
in the neighboring countries is well documented.
Our observation is the second record for Western Africa, and its presence is worrying due to the huge impacts that this species tends to have both for humans and in ecosystems (
WETTERER, 2013
). Its distribution and most probable expansion should be monitored to prevent future damages.
Several workers were found in the same spot as
B. depilis
and
S. eggersi
. This spot has no special characteristic that can make us think that this is the initial focus of infection, as it is not close to any harbor or merchandise transport hub.
