Type. ♂ holotype from Equatorial Guinea, Bioko , 5 km W Luba (3°27.9’N, 8°31.3’E), cacao plantation with fig trees, 12.–14.x.1998 (D.K. Dabney, D. Ubick), in CAS.

Boko et al.), 2♀ in CAS; same data, at night, D.K. Dabney & D. Ubick leg., 1♂ 4♀ 3 juvs. in CAS.

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

Diagnosis. Distinguished from similar congeners (large species with long abdomen, cone-shaped modified hairs on male chelicerae, simple unbranched procursus) by distinctive frontal position of distal male cheliceral apophyses ( Fig. 571 View FIGURES 569 – 574 ), distinctive small process ventrally on procursus ( Fig. 569 View FIGURES 569 – 574 ), retrolateral apophysis on male palpal femur directed toward ventrally, and anterior epigynal plate bent in lateral view (anterior part flat, posterior part strongly protruding; Fig. 516 View FIGURES 509 – 524 ).

Male (holotype). Total body length 6.4, carapace width 1.5. Leg 1: 57.8 (13.6 + 0.7 + 12.8 + 27.6 + 3.1), tibia 2: 8.9, tibia 3: 6.3, tibia 4: 8.3; tibia 1 L/d: 90. Distance PME-PME 205 µm, diameter PME 150 µm, distance PME- ALE 70 µm, distance AME-AME 25 µm, diameter AME 125 µm. Carapace ochre-yellow with brown mark posteriorly and brown lateral margins; ocular area posteriorly brown, clypeus distally brown, 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. 484–485 View FIGURES 479 – 488 , ocular area slightly elevated, secondary eyes with distinct ‘pseudo-lenses’; clypeus unmodified except longer than usual hairs; deep thoracic pit and pair of shallow furrows diverging behind pit. Chelicerae as in Fig. 571 View FIGURES 569 – 574 , with lateral proximal apophyses and distal apophyses in distinctive frontal position, the latter provided with several modified (cone-shaped) hairs. Palps as in Figs. 486–488 View FIGURES 479 – 488 ; coxa unmodified; trochanter with relatively long retrolatero-ventral apophysis; femur proximally with ventral sclerotized ridge but apparently without pocket, with retrolateral apophysis directed toward ventrally, without prolateral modification; prolateral femur-patella joint strongly shifted toward ventrally; tarsus with some stronger hairs dorsally; procursus with very indistinct hinge dividing proximal from distal part, with small ventral process, with pointed and sclerotized tip ( Figs. 569–570 View FIGURES 569 – 574 ); bulb with widened but weakly sclerotized proximal part of embolus ( Fig. 572 View FIGURES 569 – 574 ). Legs without spines and curved hairs, with few vertical hairs, retrolateral trichobothrium on tibia 1 at 1.5%; prolateral trichobothrium present on all tibiae; pseudosegments barely visible.

Variation. Number of modified hairs frontally on male chelicerae slightly variable. Tibia 1 in 4 other males: 13.6, 14.5, 16.0, 16.0.

Female. In general similar to male; clypeus with shorter hairs; sternum and clypeus variably dark. Tibia 1 in 10 females: 10.7–13.3 (mean 12.3). Epigynum relatively small, consisting of trapezoidal anterior plate bent in lateral view (anterior part flat, posterior part strongly protruding) and large posterior plate ( Figs. 515–516 View FIGURES 509 – 524 ); internal genitalia as in Figs. 528 View FIGURES 525 – 533 and 574 View FIGURES 569 – 574 .

Distribution. Known from several localities on Bioko Island, Equatorial Guinea ( Fig. 468 View FIGURE 468 ).
