Thyene pulchra
Peckham & Peckham 1903
There are two vials (MCZ:IZ:22787:
6 females
, labeled as the
type
, and MCZ:IZ:151905:
2 females
and 2 penultimate males, all from Durban) representing
Thyene pulchra
in the Peckham Collection (
Figures 9- 10
). In their description the
Peckhams (1903)
listed only
5 females
from Durban. Although the dorsal view of the female
Thyene coccineovittata
drawn by
Berland & Millot (1941
;
Figure 1
:71B) agrees with the Peckhams description of the female
T. pulchra
, to date this species has maintained a separate identity. Our female
Thyene
cf.
pulchra
from
Brazil
(
Mariante & Hill 2018
; to be updated in the near future) also agrees in general appearance with the original description of this species by the Peckhams as well as the more recent description by
Wesołowska & Haddad (2009)
.

9,
Drawing of the epigynum published by the
Peckhams (1903
, pl. XXV, fig. 3A). This compares with (3), with the anterior direction toward the bottom of the page.
The dark, paired spots of the posterodorsal opisthosoma of this species are faded but still visible in the older specimens (
Figure 9
). The epigynum (
Figure 10
) is very lightly sclerotized, and in recent specimens (
Wesołowska & Haddad 2009
) only the "parentheses" situated toward the anterior end of the epigynal plate are readily visible from the exterior. Sclerotization of these structures is much lighter than that seen in the female
T. ogdeni
(
Figure 8
). The Peckhams' drawing of the epigynum of
T. pulchra
(
Figure 10
:9) is confusing, but can best be interpreted as a sketch of the sclerotized "parentheses" of the
syntype
shown in
Figure 10
:3, with the anterior end drawn at the bottom of the figure. Presently the best reference description for the female
T. pulchra
(male not known) can be found in
Wesołowska & Haddad (2009)
.
