Paratype
:
1 female
, with same data as holotype (

)
.
Etymology.
The specific name is derived from the Latin adjective
columnaris
, -
is
, -
e
, meaning “pillar-like” referring to the lobal septum being pillar-like.
Diagnosis.
The females of this new species are similar to those of
Sinopoda tengchongensis
Fu & Zhu, 2008
(
Fu & Zhu 2008
: figs 2–3) in having similarly slender lobal septum and small posterior parts of spermathecae, but can be separated by: 1. Lobal septum of epigyne without median groove in anterior part (with median groove along entire length in
S. tengchongensis
); 2. Glandular appendages of vulva with tip slightly curved posteriad (straight and posterior-laterad in
S. tengchongensis
); 3. Internal duct system of vulva touching along median line (not touching, only close in posterior part in
S. tengchongensis
) (
Figs 16
A–B, 17A–B).

Copulatory organ as in diagnosis. Epigynal field wider than long, with short anterior bands and one slit sensillum on each side of the epigynal field. Lateral lobes fused, with groove in posterior part. Lobal septum anteriorly wider. Internal ducts running parallel along the median line, its anterior part slightly wider than posterior part. Fertilization ducts arising posterio-laterally.
Colouration in ethanol. Dorsal prosoma reddish-brown, lateral margins dark. Fovea and radial furrows distinctly marked. Labium and gnathocoxae deep brown, both with distal parts lighter.
