Tibia 1 in eight newly collected males: 1.90–2.45 (mean 2.21); in 16 newly collected females: 1.20–1.50 (mean 1.28). Tibiae 1 and 2 with higher than usual density of short vertical hairs in males only. Prolateral trichobothrium apparently absent on tibia 1. Epigynum and internal female genitalia as in Figs 13 , 17–19 .

Distribution

Known from several localities in the Venezuelan states Delta Amacuro, Bolívar, and Monagas (Fig. 1033).

Natural history

Between El Triunfo and Piacoa this species was found in the leaf litter of a humid forest, on the undersides of curved leaves on the ground. In Parque La Llovizna the forest was much dryer and the spiders lived under pieces of wood and bark on the ground, in almost the same microhabitat as Modisimus simoni Huber, 1997 in the same place.
