Etymology
The species epithet refers to the
type
locality Voimma Community Park.

Description
Holotype
clitellate,
100 mm
in length, diameter after clitellum
7 mm
, segment number 115, tail missing.
Paratypes
145–170 mm
in length,
6–7 mm
in diameter, segment number 234–268. Colour greyish, with slight reddish pigmentation at head on dorsum. Head zygolobous, segments 1–3 simple, 4–10 biannulate. Dorsal pores lacking. Setae small,
ab
and
cd
clearly observed from segment 2. Setal arrangement after clitellum aa:ab:bc:cd:dd = 23:1.5:13:1:25, dd = 0.32 U (
Fig. 4A
). Clitellum annular on segments 18–½ 28, 28. Male pores ventral on 16. Female pores not seen. Spermathecal pores in 13/14(2–3), 14/15(2–3), 15/16(2) irregularly arranged from
bc
to above
cd
. Genital setal pores in variable position between
ab
and
cd
on 15.

Internal characters
Large muscular gizzard in 5.
Septa
6/7–8/9 strongly thickened, 5/6, 9/10 less so. Calciferous glands, lamellae and typhlosolis lacking. Dorsal blood vessel simple throughout, last pair of hearts in 11. Excretory system holoic, vesiculate. Two pairs of testes and sperm funnels in 10, 11 enclosed in large peri-oesophageal testis sacs. Seminal vesicles lacking. Ovaries in 13. A pair of large, oval copulatory chambers occupying ventral space of segments 16–19. Each copulatory chamber bearing an irregular prostate-like gland (pseudoprostate) reaching segment 22. Spermathecae oval-shaped, with long and thin duct attached at 13/14(2–3), 14/15(2–3), 15/16(2) arranged from above
ab
to between
cd
and M (
Fig. 4B
). Single pair of genital setal glands present in segment 15 above
ab
and around
cd
. Genital setae slightly curved, with lanceolate apex, length
2.25–2.3 mm
, diameter just under the apex
0.07 mm
; ornamentation dense short serrations (
Fig. 4
C–D).
Remarks
This new species, with biannulate segments between 4 and 10 belongs to the
alaotranus
group (
Table 2
). In the
alaotranus
group there are only two other species possessing a single pair of genital setal glands:
K. rosae
Cognetti, 1906
and
K. minutus
Csuzdi, Razafindrakoto & Blanchart, 2012
.
K. voimmanus
sp. nov.
differs from
K. rosae
by its smaller number of spermathecal segments (13/14, 14/15, 15/16, 16/17 vs 13/14, 14/15, 15/16) and also in the structure of spermathecae (
K. rosae
possesses oval spermathecae with very short ducts,
K. voimmanus
sp. nov.
possesses oval spermathecae with thin and very long ducts, 2–3 times longer that the ampoule). The new species differs from
K. minutus
in its size and coloration, and furthermore in the position of the clitellum (18–26 vs 18–½ 28), as well as the shape of the spermathecae (short vs long spermathecal duct).
K. voimmanus
sp. nov.
is clearly different from all the examined
alaotranus
group species by its COI barcode as well (
Table 3
,
Fig. 5
).
