Additions and corrections to the redescription of
Malipatil (1994)
. Head. Median longitudinal furrow extends from middle of clypeus to middle of vertex. Labial trough cup-shaped with suture reaching only middle of venter of head. Thorax. Peritreme bulbous, dorsal flange indented.
Diagnosis.
U. elegantulus
resembles
U. woodwardi
in general appearance but can be distinguished from the latter species based on the following characters: vertex with extended blackish markings (vertex only marked basally in
U. woodwardi
); dorsal flange of peritreme indented (Fig.
9
.) (not indented in
U. woodwardi
).
Distribution.
The species was recorded from the northern parts of Australia in the following ecoregions: Arnhem land tropical savanna, Cape York Peninsula tropical savanna, Queensland tropical rainforests, Brigalow tropical savanna (
Malipatil 1994
). A specimen from Koitake, New Guinea (Southeastern Papuan rain forest ecoregion) was examined.

Germalus victoriae
(

Geocoris (Geocoris) willeyi
(

Remarks.
This species was described as
Geocoris elegantulus
(
Distant 1904
) and cited as such by subsequent authors (
Malipatil 1994
;
Cassis and Gross 2002
). A careful examination of both type and non-type specimens available concluded that the species displays synapomorphies used to define
Umbrageocoris
, including the presence of a median groove on vertex, a Y- or cup-shaped labial trough, and the arrangement of sutures at abdominal tergites 4/5 and 5/6, thus the following new combination is here proposed:
Umbrageocoris elegantulus
(Distant, 1904), comb. nov.
