Figs 747–749, 763, 770–772, 1063

Pisaboa laldea Huber, 2000: 285, figs 1151–1158 (♂).

Diagnosis (amendments; see Huber 2000)

Females are distinguished from known congeners by shape of epigynum (Fig. 770; anterior plate roughly square-shaped, without pockets, with distinctive internal arc visible in uncleared specimens) and by internal genitalia (Figs 763, 771–772; unique shape of pore plates; distinctive anterior arc).

New record

VENEZUELA – Táchira • 2 ♂♂, 2 ♀♀, ZFMK (Ar 22076), and 4 ♀♀ in pure ethanol, ZFMK (Ven20- 119), SE Pregonero, forest near La Trampa (7.9236° N, 71.7152° W), 1300 m a.s.l., 10 Feb. 2020 (B.A. Huber, O. Villarreal M., Q. Arias C.) .

Note

We were not able to exactly locate the type locality, “Camp. Siberia, Laldea”, but Campamento Siberia is at 3 km from our new collecting site, suggesting that the new site is within a few km from the type locality.

Redescription of male (amendments; see Huber 2000)

Habitus as in Fig. 747. Eye measurements (male from La Trampa): distance PME–PME 100 µm; diameter PME 110 µm; distance PME–ALE 80 µm; distance AME–AME 20 µm; diameter AME 50 µm. Abdomen with dark and white marks. Prolateral trichobothrium absent on tibia 1. Femora 1–4 approximately same maximum diameter. All tibiae with many short vertical hairs. Tibia 1 in two newly collected males: 5.7, 6.0.

Description of female

Females in general similar to males (Figs 748–749) but sternum without anterior humps and leg tibiae with few short vertical hairs. Tibia 1 in five females: 4.1–4.4 (mean 4.3). Epigynum (Fig. 770) anterior plate roughly square-shaped, posteriorly slightly elevated and with slightly protruding rim, distinctive anterior internal arc visible in uncleared specimens; posterior plate short but wide. Internal genitalia (Figs 763, 771–772) with uniquely shaped pore plates, elongated and bent in mid-section, with distinctive anterior arc (arrow in Fig. 763) and anterior median receptacle.

Distribution

Known from two neighboring localities in the Venezuelan state Táchira (Fig. 1063).

Natural history

The spiders were found ~ 0.5–1.5 m above the ground, in small webs that led into hollow branches or into shelters of dead leaves suspended among the vegetation.
