Type species.
Absonemobius tesselatus
Desutter-Grandcolas, 1993
.
Distribution.
In South America,
Absonemobius
is known from
Western
(
Peru
) and
Eastern
(
French Guiana
) Amazonia (
Desutter-Grandcolas 1993
). Its presence is confirmed in southern Central America with
Hygronemobius darienicus
Hebard, 1913
from
Panama
, transferred to
Absonemobius
in the present paper, and
A. alatus
Otte, 2006
from
Costa Rica
. It is attested here from the first time from the lesser Antilles (
A. septentrion
,
n. sp.
,
A. lucensis
,
n. sp.
,
A. vincenti
,
n. sp.
).
Diagnosis and description.
See
Desutter-Grandcolas (1993)
.
Habitat.
Diurnal species foraging in the leaf litter of closed rainforest.
Remark.
A. septentrion
n. sp.
,
A. lucensis
n. sp.
,
A. vincenti
n. sp.
, and
A. alatus
are all closely related. They are characterized by their asymmerical male genitalia, with a deep notch on the left side of pseudepiphallic sclerite, and the very long median lobes, fused into a long process, concave in lateral view. These characters may support the definition of a new genus, but as no morphological character supports this hypothesis we keep these species in the genus
Absonemobius
.
