Panjange iban Huber, 2011: 119–121 ; figs 469–488, 770–772, 791–792 (Ƌ ♀).

Diagnosis

Distinguished from similar species (with ventral apophysis on palpal femur, without pointed processes on eye stalks: Pa. kubah sp. nov.; Pa. nigrifrons ; Pa. seowi sp. nov.) by distinctive ventral process of procursus (near distal end of ridges; fig. 470 in Huber 2011); females are difficult to distinguish externally from congeners in Sarawak (distinctive internal folds arranged in anterior semicircular pattern; large pore plates); from Pa. nigrifrons by very short scape.

New material examined

MALAYSIA-BORNEO, Sarawak: 2 ƋƋ, 7 ♀♀, Semengoh Arboretum, Masing Trail (1.397– 1.399° N, 110.317– 110.322° E), 60–80 m a.s.l., 17 July 2014 (B.A. Huber), ZFMK ( Ar 14585 ) ; 2 ♀♀, 2 juvs, same data, in absolute ethanol, ZFMK ( Bor 227 ) ; 6 ƋƋ, 3 ♀♀, same locality, Apr. 1985 (C.L. & P.R. Deeleman), RMNH .

Natural history

The webs had a diameter of about 10–20 cm and were found among vegetation in primary forest close to the ground where the domed sheets were attached to the undersides of leaves.
