Anansi luki Benavides and Hormiga View in CoL new species Figures 9 – 13 View Fig. 9 View Fig. 10 View Fig. 11 View Fig. 12 View Fig. 13
Types. Male holotype from D.R. CONGO: Bas Congo, Mayombe , Luki Forest Reserve , hand catch, primary rainforest, on forest tree trunk along fogging site, Re. De Bakker, D. and Michelis J.P. 3.xi.2006 ( RMCA. 22055 - GH0797 ); female paratype, same locality as the holotype, old secondary rainforest near FS 11, 24.ix. 200 7 ( RMCA.22215 1-GH0798).
Etymology. The species epithet is a noun in apposition taken from the type locality.
Diagnosis. Anansi luki can be distinguished from its congeners by having a long ectobasal cymbial process (CEBP) that is half the total cymbium length ( Figs. 10 View Fig. 10 B, E) (in A. insidiator the CEBP is shorter); conductor flagellum 1.5 times maximum width of cymbium (in A. insidiator flagellum as long as maximum width of cymbium), and epigynum’s bifid distal end that fold upwards ( Figs. 14 View Fig. 14 A – C) (In A. insidiator the distal end of the epigynum is entire and folding downwards).
Description. Male: ( Figs. 9 View Fig. 9 and 10 View Fig. 10 ; GH797-GH798). Habitus as in Figures 9 View Fig. 9 A – C. Total length 5.37; cephalothorax 2.78 long, 1.71 wide, 0.67 high; abdomen 2.48 long, 1.35 wide, 1.30 high. Carapace pale yellow with two lines of macrosetae that run from the fovea to the ocular area ( Fig. 9 View Fig. 9 A). Sternum yellowish ( Fig. 9 View Fig. 9 C), 1.08 long, 0.80 wide, labium 0.41 long, 0.39 wide, darker than the sternum ( Fig. 9 View Fig. 9 C). Clypeus 0.19 high; AME inter-distance 0.11, PME 0.05. PME-AME distance 0.15; AME-ALE 0.08; PME-PLE 0.17. Chelicerae yellow with distal margins dark brown ( Fig. 8 View Fig. 8 D); ChL 1.08; ChW1 0.30; ChW2 0.29. Cymbium twice as long as wide, bearing a fingershaped process on base of ectal margin, adjacent to paracymbium ( Figs. 10 View Fig. 10 B, E – F). Paracymbium spoonshaped; tegulum discoid, embolus flagelliform, running parallel to tegulum ( Fig. 1 View Fig. 1 0C – D); conductor projecting ventrally, with a flagellum almost as long as embolus ( Figs. 10 View Fig. 10 A, C). Epiandrous fusules in two clusters; each cluster on a protuberance that carries ca. 11 fusules ( Fig. 10 View Fig. 10 G).
Female: ( Figs. 12 View Fig. 12 and 13 View Fig. 13 ; GH795-GH797). Habitus as in Figures 12 View Fig. 12 A-C. Total length 4.77, cephalothorax 2.17 long, 1.27 wide, 0.64 high; abdomen 2.60 long 1.39 wide, 1.49 high. Carapace pale yellow with two lines of setae that run from fovea to ocular area ( Fig. 1 2 View Fig. 1 View Fig. 2 A). Sternum light yellow with some scattered grey spots, 1.13 long, 0.73 wide. ( Fig. 12 View Fig. 12 C). Labium 0.38 long, 0.34 wide. Clypeus 0.15 high; AME interdistance 0.13, PME 0.05. PME-AME distance 0.19; AME-ALE 0.11; PME-PLE 0.18 ( Fig. 12 View Fig. 12 D). ChL 1.44; ChW1 0.36; ChW2 0.39. Epigynum projecting posteriorly twice as long as wide; wider at base and narrower distally ( Figs. 12 View Fig. 12 E – F; 13A – C). Oval spermathecae ( Figs. 12 View Fig. 12 F); copulatory ducts 1.2 times spermathecae length ( Fig. 13 View Fig. 13 F). Spinnerets as in Figures 13 View Fig. 13 E – F. PLS without cylindrical spigots ( Fig. 13 View Fig. 13 F – G).
Distribution. Known only from the Democratic Republic of Congo and Gabon.
