(transfer, description of female)
Note:
Strand (1913)
did not describe the female as mentioned in the
World Spider Catalog (2018)
, but Deeleman-
Reinhold (2001)
.
Amended diagnosis.
Small to medium sized spiders with body length of males: 9.4, of females: 10.1. Males are similar to
S. insulana
and
S. princesa
spec. nov.
in having a similar conformation of the palp including arising point and shape of embolus and the simple, stretched RTA (
Figs 40–41
), but may be distinguished from the former by the male RTA with base relatively very wide (=a) and very short distal part (=b, best seen in retrolateral view,
Fig. 41
; with a/b=1.4; 1.0 in
S. insulana
,
Fig. 44
) and from the latter by the relatively shorter RTA base in comparison to the maximal cymbium width in retrolateral view, i.e. a <width (a> width in
S. princesa
spec. nov.
). Females are similar to those of
S. dentata
in having similarly bent copulatory ducts leading to connecting tubes between bursae and spermathecae as well as relatively small bursae, but may be distinguished by copulatory ducts roughly right-angled (U-shaped in
S. dentata
) and copulatory openings surrounded by strongly sclerotised rims opened medially (with closed rims in
S. dentata
).
Description.
See
Deeleman-Reinhold (2001)
. One pair of slit sensilla and only few sclerotised spheres are present in the female epigyne.
Distribution.
Known only from the
type
locality (
Figs 45–46
).
Natural history.
The label suggests that specimens were found in the forest in an altitude between
1000 and 1500
metres.
