Figs 754–756 ), and by shape of epigynal plate ( Fig. 767 ; anterior plate oval with pair of deep pockets in anterior half; with pair of whitish processes in front of epigynum), and by internal female genitalia ( Figs 762 , 768–769 ; long narrow pore plates; distinctive shape of anterior putative receptacle). From very similar P. fombonai Huber sp. nov. also by more proximal position of male cheliceral apophyses ( Fig. 761 ). Etymology This species is named for María Lionza, a central figure in one of the most widespread indigenous religions in Venezuela that blends African, indigenous, and Catholic beliefs.

P. fombonai Huber sp. nov. ; from Mérida, Caño Azul (type locality; ZFMK Ar 22073). 767–769 . P. lionzae Huber sp. nov. ; from Mérida, Mesa Bolívar (type locality; ZFMK Ar 22075). 770–772 . P. laldea Huber, 2000 ; from Táchira, La Trampa (ZFMK Ar 22076). BODY. Habitus as in Fig. 745 . Ocular area moderately raised. Carapace with shallow but distinct thoracic groove. Clypeus unmodified. Sternum wider than long (0.72/0.44), with pair of very low whitish and elongate humps anteriorly. Abdomen slightly elongated, pointed at spinnerets. CHELICERAE. As in Fig. 761 , with pair of articulated apophyses frontally. PALPS. In general very similar to P. silvae and P. mapiri (cf. Huber 2000 : figs 1137, 1143, 1146); largely indistinguishable from P. fombonai Huber sp. nov. but larger (femur length: 400 vs 310 µm ; tibia length: 380 vs 300 µm ; bulb length: 640 vs 440 µm ); coxa with large retrolateral-ventral apophysis, trochanter barely modified, femur proximally with retrolateral process, distally widening, with short finger-shaped ventral process; tarsus with two short rounded processes dorsally; procursus ( Figs 758–760 ) wide and slightly S-shaped in lateral view, narrow and strongly bent in dorsal view, with distinctive distal elements; genital bulb largely identical to P. fombonai Huber sp. nov. (cf. Figs 754–756 ). LEGS. Without spines and curved hairs; with vertical hairs in high density on all tibiae; retrolateral trichobothrium of tibia 1 at 6%; prolateral trichobothrium absent on tibia 1; tarsus 1 with ~25 pseudosegments, distally fairly distinct. Female In general similar to male ( Fig. 746 ) but sternum dark brown, dark rings on legs more distinct; sternum without humps but with longer hairs than in male, especially posteriorly; vertical hairs on tibiae in usual low density. Tibia 1 in nine females: 3.9–4.8 (mean 4.3). Epigynum ( Fig. 767 ) oval light brown plate, posteriorly weakly protruding, with pair of deep pockets in anterior half; internal structures partly visible in uncleared specimens; with short but wide posterior plate and pair of low whitish processes in front of epigynum. Internal genitalia ( Figs 762 , 768–769 ) with long narrow pore plates, distinctive shape of anterior putative receptacle (W-shaped). Distribution Known from type locality only, in Venezuela , Mérida (Fig. 1063). Natural history The spiders were collected in a well-preserved forest along a small stream. All specimens were found ~ 1–2 m above the ground, in masses of dead leaves suspended among the twigs or lianas, one specimen in a dead Heliconia leaf, one specimen on a tree trunk. Adults and juveniles looked similar and occupied the same microhabitat.
