SYSTEMATICS OF PORTERIA SPIDERS 435

into obscurity. Scape absent ( Fig. 55E ); epigyne small. Vulva with copulatory duct of medium length; head of spermatheca well differentiated from stalk. Left and right stalks elongated, straight and parallel to each other ( Fig. 55G ), closer together than in P. faberi . Base 1 in dorsal view appearing less circular than P. faberi . Atrium ventral wall about equivalent height to spermatheca, shallowly ‘M’-shaped, unlike the arch shape of P. faberi that extends well beyond spermatheca. Bennett’s gland pore visible in lateral view on Base 1.

Leg measurements (right): leg I 10.95 (2.90, 3.70, 2.60, 1.75); leg II 9.35 (2.65, 3.05, 2.25, 1.40); leg III 8.95 (2.50, 2.75, 2.40, 1.30); leg IV 11.70 (3.15, 3.60, 3.35, 1.60); palp 3.85 (1.25, 1.30, –, 1.30).

Distribution: Known only from the type locality in XIV Región de Los Ríos, Valdivia Province ( Fig. 76C ).

Other material examined: None.
