Grossander (Oculoander) papuanus
sp. nov.
(

,

)
Structure
: Very similar to
G. (O.) e yl e s i
, with the following differences. Body above dull, pubescence of antennal segment I semi-erect, and on lateral side about as long as diameter of antennal segment II. Head more convex in lateral view, densely punctate, distance between antenna and eyes longer (about 1.1 times) than eye length. Eyes stalked, head strongly narrowed behind it. Length of pronotal collar 1.5 times width of tibiae. Lateral carina on anterior pronotal lobe very broad, much broader than in posterior half and broader than tibiae. Anterior femora with 6–8 small spines apically from greater tooth.
Male genitalia
: Pygophore (
Fig. 5
) similar to
G. ey l es i
but with longer and more extended pubescence. Paramere (
Fig. 7–8
) on outer arm with nearly straight apex; inner projection rounded, without angulate apex; with long setae.
Colour
: Similar to
G. (O.) eylesi
, only antennal segment IV dark, at least in basal half. Triradiate scutellar arm fully pale.
Measurements
(all in mm;
holotype
first, followed by ranges of
paratypes paratypes
in parentheses): Total body length 5.10 (4.55–5.22). Head: length 0.88 (0.75–0.92), width 0.99 (0.90–1.00), interocular space 0.61 (0.55–0.60). Pronotum: length 1.05 (0.85–1.05), width at base 1.56 (1.38–1.62). Scutellum: length 1.02 (0.80–0.92), length of claval commissure 0.54 (0.38–0.40). Lengths of antennal segments I 0.68 (0.62), II 0.88 (0.72–0.80), III 0.83 (0.70–0.75), IV? [segment missing] (0.72–0.75). Lengths of labial segments of
holotype
I 0.49, II 0.51, III 0.5, IV 0.37.
Some relative measurements
(ratios are calculated from the measurements of
holotype
and 5
paratypes
, and given in intervals). Body length: pronotum width at base 3.2–3.3; body length: antenna length 1.6–1.8; pronotum width: length 1.5–1.6; pronotum width: head width 1.5–1.6; head width: length 1.2; scutellum length: length of claval commissure 2.1–2.3; length of antennal segments II: I 1.1–1.3; III: II 0.9–1.0.

Diagnosis.
Grossander (Ocuoalander) papuanus
is distinguished from
G
.
(G.) major
(
Gross, 1965
)
by the stalked eyes, greater distance between anterior of eye and antennal insertion, and by the longer, more robust collar.
Etymology.
The name of the species refers to New
Guinea
, the distribution area.

Discussion.
The previously known Australian species of the genus
Grossander
are clearly distinct from both new species in the features specified in the discussion of the new subgenus. The most similar is
Grossander (Grossander) major
(
Gross, 1965
)
shown in
Fig. 3
, especially in armature of fore femora and body size. However, the fore femur in the new subgenus,
Oculoander
, is armed with fewer teeth (
G. (G.) major
has about 7+10 teeth in two rows). The punctures of the head and the pronotum are sparser, irregular. The shape of the pygophore and the pygophore opening of
G. (G.) m a j o r
are more rounded than in the figure published with the original description (
Fig. 6
) (
Gross 1965
); these are very similar to
G. (O.) eylesi
. The paramere of
G. (G.) major
is intermediate between those of the new species, the projections being somewhat angulate (as in
G. (O.) eylesi
), but the outer arm is nearly straight (as in
G. (O.) papuanus
). The distribution of
G. (O.) papuanus
and
G. (O.) eylesi
can be seen on
Fig. 11
