Loxosceles spinulosa
Purcell, 1904: 140
;
Newlands, 1975: 144
, f. 2–5, 8, 10–13; 1986: 77, f. 52–54.
Types:
♀
Holotype
from
South Africa
: Swellendam, Pass at Avontuur, near Stormsvlei, [3404'S, 2005'E],
W.F. Purcell
,
August 1900
[SAM-ENW-X007915—examined].
Diagnosis: Male palp cymbium and tibia short, similar to
L. bergeri
,
L. pilosa
,
L. simillima
and
L. smithi
; differing from these species and all other species in the embolus ending in a flattened spiral (
Fig. 9L
). Female spermathecae consist of two, small, round sacs; two thin copulatory tubes extend from the spermathecae, joined centrally; posterior of paired tubes longer and bent before entering spermathecae; similar in some respects to
L parramae
,
L. simillima
and
L speluncarum
; differing from
L. simillima
and
L. speluncarum
in the copulatory tube being long between the copulatory opening and the split in the copulatory tube; differing from
L. parramae
in the copulatory tubes being long after the split (
Fig. 10K
).

| Types: ♀ Holotype and 2♀ paratypes from Namibia: Grootfontein, Uisib 427, Uhlenhorst Cave, 1935'S, 1713'E, P. von Wrede; 1♂ and 1♀ paratypes from Namibia: Otavi Cave, 1940'S, 1715'E, F. Gaerdes [SMN 36435 and NM 8837—not seen]. |
| Note: The type specimen was not among the specimens received on loan from the NMNW collection. Other specimens from the type localities were examined. |

Diagnosis: Male palp tibia long, cymbium short, similar to
L. fontainei
,
L. foutadjalloni
,
L. rufescens
and
L. rufipes
; differing from these species in the palp tibia length/height ratio being more than 2.5 (Fig. 9M). Female spermathecae consist of a round sac on a long copulatory tube that widens towards the copulatory opening; posteriolateral of the copulatory tubes there are two short tubes on each side; differ from all other species in this respect (Fig. 10L).
