Panjange nigrifrons Deeleman-Reinhold & Deeleman, 1983

Figs 5 , 86–88

Panjange nigrifrons Deeleman-Reinhold & Deeleman, 1983: 126–128 ; figs 10–16 (Ƌ ♀).

Diagnosis

Distinguished from similar species (with ventral apophysis on palpal femur, without pointed processes on eye stalks: Pa. iban ; Pa. kubah sp. nov.; Pa. seowi sp. nov.) by low number of ridges ventrally on procursus (only three; fig. 13 in Deeleman-Reinhold & Deeleman 1983); by short male palpal trochanter apophysis (fig. 15 in Deeleman-Reinhold & Deeleman 1983), and by distinctive female genitalia ( Figs 86–88 ; internal lateral structures visible through cuticle; long scape).

New material examined

INDONESIA-BORNEO, East Kalimantan: 2 ƋƋ, 2 ♀♀, Sepaku [~ 0.91° S, 116.77° E], 40 km N of Balikpapan (type locality), primary forest , 20– 21 Jul. 1982 (collector unknown), RMNH .

Description – amendments

Male distal cheliceral apophyses clearly bipartite as in other species described herein (this was correctly noted in the original description but not correctly drawn in fig. 11). Appendix with very distinct and unique pocket at ~60% of its length. Tibia 1 L/d: 100; tibia 2/tibia 4 length: 1.09 (not 1.33 as in original description); distance PME–PME: 420 µm; retrolateral trichobothrium at 2%.

Distribution

Known from two localities in Kalimantan only ( Deeleman-Reinhold & Deeleman 1983; Fig. 1 ).
