Figs. 533–540 View FIGURES 525 – 533 View FIGURES 534 – 540 , 621–626 View FIGURES 621 – 626

Type. ♂ holotype from Congo D.R., Bas Congo Province, Luki Forest Reserve (5°37.3’S, 13°05.9’E), central zone, by hand, 26.–27.ix.2007 (W. Hubau), in MRAC (222155 part).

Other material examined. CONGO D.R.: Bas Congo: Luki Forest Reserve, 1♀ together with holotype; same data, 1♀ in MRAC (222232); same locality, along trail near guest house, by hand, 18.–19.ix.2007 (W. Hubau), 1♂ in MRAC (222141); same locality, primary rainforest, by hand, 20.ix.2007 (D. de Bakker, J.P. Michiels, W. Hubau), 1♀ in MRAC (223577). Weka [5°42.1’S, 12°35.4’E], viii.1937 (E. Dartevelle), 1♀ in MRAC (26854).

Etymology. The name is a noun in apposition, derived from the type locality.

Diagnosis. Easily distinguished from similar congeners (large species with long abdomen, cone-shaped modified hairs on male chelicerae, simple unbranched procursus) by distinctively wide procursus ( Figs. 621–622 View FIGURES 621 – 626 ), sclerotized rod-shaped embolus ( Fig. 624 View FIGURES 621 – 626 ), and medially protruding rim of anterior epigynal plate ( Figs. 539 View FIGURES 534 – 540 , 625 View FIGURES 621 – 626 ).

Male (holotype). Total body length 7.8, carapace width 1.9. Leg 1: 83.6 (18.9 + 0.8 + 18.7 + 41.3 + 3.9), tibia 2 missing, tibia 3: 8.7, tibia 4: 11.1; tibia 1 L/d: 101. Distance PME-PME 175 µm, diameter PME 185 µm, distance PME-ALE 70 µm, distance AME-AME 60 µm, diameter AME 160 µm. Carapace ochre-yellow with brown triangular mark posteriorly and brown lateral margins, whitish behind ocular area; ocular area brown, clypeus brown in lower half, sternum dark brown; legs ochre-yellow, slightly darker rings subdistally on femora and tibiae and in patella area, tips of femora and tibiae whitish; abdomen ochre-gray with distinct black pattern dorsally, laterally, and ventrally. Habitus as in Figs. 534–535 View FIGURES 534 – 540 , ocular area slightly elevated, secondary eyes with distinct ‘pseudo-lenses’; clypeus unmodified but with longer than usual hairs; deep thoracic pit and pair of shallow furrows diverging behind pit. Chelicerae as in Fig. 623 View FIGURES 621 – 626 , with lateral proximal apophyses and distal apophyses, the latter and frontal cheliceral face provided with several small modified (cone-shaped) hairs. Palps as in Figs. 536–538 View FIGURES 534 – 540 ; coxa unmodified; trochanter with retrolatero-ventral apophysis; femur proximally with ventral sclerotized ridge, without or with very indistinct shallow pocket, with small retrolateral apophysis, without prolateral modification; prolateral femur-patella joint strongly shifted toward ventrally; tarsus with several strong hairs dorsally; procursus very wide, with very indistinct hinge between proximal and distal part ( Figs. 621–622 View FIGURES 621 – 626 ); bulb with rod-shaped, sclerotized embolus ( Fig. 624 View FIGURES 621 – 626 ). Legs without spines and curved hairs, with few vertical hairs (most hairs missing), retrolateral trichobothrium on tibia 1 at 1%; prolateral trichobothrium present on all tibiae; pseudosegments barely visible.

Variation. Tibia 1 in second male: 18.4.

Female. In general similar to male. Tibia 1 in 2 females: 14.0, 16.7 (missing in other females). Epigynum consisting of large anterior plate with distinctively protruding rim, and arc-shaped posterior plate ( Figs. 539–540 View FIGURES 534 – 540 ); internal genitalia as in Figs. 533 View FIGURES 525 – 533 and 626 View FIGURES 621 – 626 .

Distribution. Known from two localities in Bas-Congo Province, Congo D.R. ( Fig. 468 View FIGURE 468 ).
