Notes
The newly collected specimens below slightly deviate from the
types
and are thus assigned tentatively to this species. In particular, the main sclerotized processes of the genital bulb (uncus and appendix) have a slightly different shape, and the slender transparent process is slightly shorter (compare
Figs 715 and 716
). The pore plates in the female internal genitalia are round rather than oval (
Fig. 714
) and the large lateral elements in the female internal genitalia seem to be slightly different in shape (however, this may partly be an artifact of preparation). Most newly collected males with complex dark mark in posterior half of carapace (
Figs 708–709
), but this character is variable. Females with less ‘complete’ mark on carapace (
Fig. 710
). Tibia
1 in
nine newly collected males: 4.8–6.3 (mean 5.8); in six newly collected females: 4.6–5.3 (mean 4.8).

Distribution
Known from two localities in the Venezuelan states
Sucre
and
Miranda
(Fig. 1056). Specimens from
Miranda
are assigned tentatively (see Notes above).
Natural history
Most new specimens were collected in a very limited, strongly disturbed, and arid area near the entrance to El Ávila National Park. At two superficially similar neighboring localities no or very few specimens were found. The spiders were resting either in dead bamboo culm sheaths on the ground or in rotten bamboo trunks. A single bamboo trunk sometimes contained several adult specimens. A single juvenile specimen (
Fig. 711
) was found on a live leaf in a neighboring site, close to a small stream.
