Distribution.
Ascension Island
(new record, introduced),
Brazil
(introduced,
Brescovit
et al
. 2019
), and
USA
(
Platnick
et al
. 2011
).
Remarks.
Brignolia dasysterna
seems to be a more recent introduction to
Ascension
from the
United States
, in keeping with other recently discovered non-native species (Sherwood
et al
. in prep). It is not present in older samples. The habitus and genitalia of this species has been excellently illustrated elsewhere (
Platnick
et al
, 2011
;
Brescovit
et al
. 2019
), complete with comprehensive descriptions. Therefore, we simply provide here two complimentary photographs showing the key characters to identify male
B. dasysterna
: the modified setae of the sternum (
Fig. 1H
) and the medial keel of the dark and elongate palpal bulb (
Fig. 1I
).
