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 View Figs 764–772 ; anterior plate roughly square-shaped, without pockets, with distinctive internal arc visible in uncleared specimens) and by internal genitalia ( Figs 763 View Figs 758–763 , 771–772 View Figs 764–772 ; 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.) GoogleMaps   .

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 View Figs 742–749 . 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 View Figs 742–749 ) 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 View Figs 764–772 ) 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 View Figs 758–763 , 771–772 View Figs 764–772 ) with uniquely shaped pore plates, elongated and bent in mid-section, with distinctive anterior arc (arrow in Fig. 763 View Figs 758–763 ) 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.
