Description. External.
Holotype
:
Body length>
110 mm
, abscised, width
8 mm
at tubercula. Segment number> 200.
Paratype
:>
250 mm
in length, abscised, width
8 mm
. Segment number> 300. Colour whitish grey. Prostomium prolobous. Preclitellar segments with secondary annulations: segment 1 and 2 simple, 3 with superficial line, 4–6 divided by one furrow, the anterior annulus again subdivided giving four annuli per segment; 7, 8, 9 also with annuli subdivided to make a total of 5, 6, 8 annulations, respectively.

minute, closely paired especially on papillae. Male pores not observed. Female pores not observed. Spermathecal pores not observed, presumably at intersegmental furrows of
12/13–16/17
, corresponding to the number and location of the spermathecae. Clitellum saddle-shaped on 12–27, 28, segmented, appears as a band of discolouration. Tubercula pubertatis not clear on 17,18–21. Genital papillae on 10–28 or 10–26 on
paratype
.
Internal.
Septa 4/5, 5/6, 6/7 thickened, muscular (
Fig. 1
). Other septa thin. Gizzard well developed in 7, globular, muscular. Calciferous glands in 9, fused dorsally. Intestinal origin in 12. Dorsal blood vessel simple throughout the body. Nephridia holoic, one pair per segment with J-shaped bladders. Holandric, male funnels in separate sacs, closely paired. Seminal vesicles very small, one pair in 11. Spermathecae near
cd
setal line, one pair per segment in 12–16 near intersegmental furrows
12/13–16/17
, one pair per segment, small, round-shaped with long diverticulum. Genital glands present on 10–26 or 28.
Etymology
. Refers to the
type
locality, Kleinood Farm.
Remarks
. This species is similar to
K. pearsonianus
(
Pickford, 1975
)
with muscular septa at 4/5–6/7 but differs by the position of calciferous glands in segment 9 (in
10 in
K. pearsonianus
).
K. kleinoodi
sp. n.
has five pairs of spermathecae whilst
K. pearsonianus
has three. Furthermore, the clitellum in
K. kleinoodi
is on 12–27 and extends slightly to
28 in
the
paratype
, but it covers segments
11–28 in
pearsonianus
.
K. nietvoorbiji
sp. n.
and
K. nieuwoudtvillensis
sp. n.
(see below) also have thickened septa 4/5–6/7 but differs from
K. kleinoodi
in the number of spermathecae (5, 6, 4 respectively). Some of the characters specific for this species are indicated in
Table 1
.
