Spermophora dieke View in CoL n. sp.
( Figures 12 View Figures 7–14 , 36–40 View Figures 32–44 , 124–127 View Figures 124–127 , 150 View Figures 150–151 )
Type
Male holotype from Forêt Classée de Diéké (7°32.0′N, 8°49.9′W), Guinée Forestière, Guinea; 430 m a.s.l., 1.xii.2008 (B.A. Huber), in ZFMK .
Etymology
The species name is taken from the type locality and used as a noun in apposition.
Diagnosis
Easily distinguished from known congeners by the strong median projection on the male clypeus ( Figure 36 View Figures 32–44 ), and the distally unmodified male chelicerae. A probably closely related, undescribed species (with very similar male palps and chelicerae) occurs in Ghana (deposited in MRAC), but in that species the male has paired clypeus projections (B.A. Huber, unpublished data).
Male (holotype)
Total body length 1.9, carapace width 0.7. Leg 1 missing, tibia 2: 2.9, tibia 3: 1.9, tibia 4: 2.8, tibia 2 L/d: 43. Habitus as in Figures 36 and 37 View Figures 32–44 ; carapace whitish grey with black margin and short posterior line medially, ocular area and clypeus also mostly black, chelicerae without black marks, sternum pale grey, legs pale ochre-yellow with black marks on femora and tibiae subdistally, abdomen whitish-grey with black marks dorsally and laterally, ventrally two pairs of black marks frontally. Distance PME–PME 115 µm, diameter PME 105 µm, distance PME–ALE 35 µm, no trace of AME. Each triad slightly elevated. No thoracic furrow, only median dark line. Clypeus with distinctive median projection with bifid tip. Chelicerae without distal modification, only pair of light proximo-lateral apophyses. Sternum wider than long (0.55/0.40), unmodified. Palps as in Figures 124 and 125 View Figures 124–127 , coxa unmodified, trochanter with long ventral and retrolateral apophyses, procursus with retrolatero-ventral flap, distally complex with long sclerotized filament, bulb with proximal sclerite, membranous embolus and sclerotized hooked bulbal apophysis. Legs without spines and curved hairs, few vertical hairs; retrolateral trichobothrium on tibia 2 at 10%; tarsal pseudosegments indistinct, distally ∼10 visible in dissecting microscope.
Female
In general similar to male ( Figure 39 View Figures 32–44 ), triads only slightly closer together (distance PME–PME 95 µm), clypeus unmodified. Tibia 1: 4.4 (missing in other female); tibia 2: 2.6, 2.3. The two females differ in extent of black pigment: darker female with black sternum and more spots dorsally on abdomen. Epigynum light brown, trapezoidal, weakly protruding, frontal internal structures visible through cuticle ( Figures 38 View Figures 32–44 , 126 View Figures 124–127 ); internal genitalia as in Figures 40 View Figures 32–44 and 127 View Figures 124–127 .
Distribution
Known from type locality in Guinea only ( Figure 150 View Figures 150–151 ).
