); apex strongly sclerotized in lateral view; endophallic brush not protruding, basal orifice rectangular in ventral view.
Diagnosis.
Neobarombiella salisburiensis
can be best identified by its characteristic metallic greenish or blueish colouring and coarse elytral punctuation. Although
N. nigrita
and
N. punctatolineata
are similar to
N. salisburiensis
in appearance, they have no metallic colouring. Short, broad elytron are also characteristic of
N. nigrita
, width of both elytra to length of elytron 0.72–0.82 (mean: 0.77) (
N. salisburiensis
0.63–0.71 (mean: 0.68);
Figs 24
,
54
), whereas
N. punctatolineata
has elytral punctuation arranged in short striae and it has a short second antennomere, length of second to third antennomere 0.56–0.71 (mean: 0.62) (length of second to third antennomere in
N. salisburiensis
0.72–0.83 (mean: 0.77);
Figs 50
,
56
).
Neobarombiella nigrocaerulea
is similar to
N. salisburiensis
in appearance, having a yellow to yellowish-red pronotum and dark metallic elytra, but different in that its elytron only have microsculpture. Its second antennomere is only half to two-thirds as long as the third antennomere, length of second to third antennomere 0.50–0.65 (mean: 0.57) (length of second to third antennomere in
N. salisburiensis
0.72–0.83 (mean: 0.77);
Figs 35
,
56
). Two other species, namely
N. mendica
and
N. apicalis
, also resemble
N. salisburiensis
, in having reddish or yellowish-brown pronotal colouring, but only
N. mendica
occurs sympatrically with
N. salisburiensis
.
Neobarombiella apicalis
is known from
the Democratic Republic of the Congo
and the vicinity of the Albertine Rift (
Figs 57
,
68
,
109
); the elytron of
N. mendica
are a glossy black, and those of
N. apicalis
dark metallic green or bluey, but both have a red or brownish-red apical tip; the third antennomere in
N. mendica
is only half as long as the fourth, length of third to fourth antennomere 0.44–0.57 (mean: 0.50) (
N. salisburiensis
0.75–0.85 (mean: 0.80);
Figs 56
,
67
); the pronotum in
N. mendica
is on average shorter and broader, pronotal length to width 0.45–0.54 (mean: 0.50) (0.52–0.57 (mean: 0.54) in
N. salisburiensis
) (
Figs 54
,

).
