, fig. 1, female
holotype
from
Yawakuri river
,
Upper Demerara-Berbice
Guyana
[
05°18’N
,
58°22’W
],
July 1919
,
A. A. Abraham
leg
., deposited in BMNH (examined).
Note.
The match between males and females was made after the examination of the female
holotype
, since many males and females were found together in the same vial in some Brazilian collections.
Diagnosis.
The females of
T. abrahami
resemble those of
T. onca
sp. nov.
(
Fig. 107
) and
T. hirsutochela
sp. nov.
(
Fig. 107
) in the general shape of the middle field (
Fig. 80
), but can be distinguished by “hood-like” shape of the middle field (
Fig. 80
), by the conspicuous hood (
Fig. 80
) and by the shape and the projected pores on the head of spermathecae (
Figs 81, 82
). The males resemble those of
T. caxiuana
sp. nov.
in the shape of the apex of the median apophysis (
Fig. 89
), but can be distinguished by the slightly longer median apophysis (
Fig. 84
) and by the longer and triangular shape of the ectal branch of RTA (
Figs 85–87
).
