Description
: Body length
2.8–3.5 mm
(M =
3.1mm
, HT =
3.4 mm
), forebody length
1.7–1.8 mm
(M =
1.7 mm
, HT =
1.7 mm
). Black to dark brown, abdomen brown, legs and antennae yellowish-brown (
Fig. 1
).
Head (
Figs. 1, 2
) moderately convex, a third wider than long (W/L = 1.28–1.35, M = 1.31, HT = 1.28). Surface, except for small unpunctured middle area rugosely, moderately coarsely and very densely punctured, punctures slightly smaller as basal diameter of second antennal segment, surface with traces of microsculpture consisting of transverse mesh. Labrum (
Fig. 4
) medially emarginated, with short internal lobes. Antennae moderately short, segments 1–9 longer than wide, segment 1 about as long as than segments 2 and 3 combined, fifth segment longer than wide (L/W = 1.43–1.74, M = 1.56, HT = 1.56), tenth segment about as long as wide (L/W = 0.95–1.14, M = 1.04, HT = 1.11).
Pronotum (
Fig. 1
) rounded trapezoidal, moderately convex, almost as long as wide (L/W = 0.95–0.98, M = 0.97, HT = 0.97) and markedly narrower than head (PW/HW = 0.82–0.84, M = 0.83, HT = 0.84). Sides markedly narrowed posteriorly. Surface, except for moderately wide unpunctured line rugosely, moderately coarsely and very densely punctured, slightly sparsely than on head, most interstices markedly smaller than diameter of punctures, surface with traces of microsculpture. Unpunctured line in narrowest part in middle of pronotum less than twice as wide as diameter of puncture.
Elytra (
Fig. 1
) rounded trapezoidal, flattened on disc, almost about a quarter wider than long (R = 1.18–1.34, M = 1.28, HT = 1.24. Sides markedly widened behind.
Abdomen (
Fig. 1
) slightly widened to segment VI, very finely and sparsely punctured. Interstices on tergite VII about 2–3 larger than diameter of punctures. Surface with very fine microsculpture consisting of transverse mesh.

Male. Sternites III–VII without modifications, posterior margin of sternite VIII (
Fig. 6
) largely and markedly deeply triangularly emarginate. Aedeagus (
Figs. 7–15
)
0.55–0.69 mm
(M =
0.59 mm
, HT =
0.56 mm
). Median lobe with apical process narrow in ventral view and not bent dorsally in lateral view.
Female. Sternite VIII largely rounded posteriorly.
Differential diagnosis.
N. capensis
sp. nov.
differs from
N. zulu
sp. nov.
and
N. tragardhi
(
Fagel, 1961
)
by the finely and densely punctured head and pronotum, and by the different shape of the aedeagus.
Etymology.
This species is named after the Province
Eastern Cape
, where the
type
locality is situated.
Distribution.
Neopimus capensis
sp. nov.
is currently recorded from Mbotyi, Ntsubane, Silaka and Isidenge Forests in
Eastern Cape Province
,
South Africa
.
Bionomics.
All specimens have been found in siftings of forest litter in indigenous forest.
