(Figs. 4–9, 17A –C)
Type material. IVORY COAST: Vallée du Bandama: holotype male, WARDA site, Bouaké, Bouaké Department, 7°41’N, 5°02’W, July 28, 1994, pitfalls, rice, A. Russell-Smith (MRAC 227.388, PBI_OON 32984). Paratype: 1 female, same data as holotype (MRAC 241.394, PBI_OON 32983).
Other material examined. IVORY COAST: Vallée du Bandama: 1 male, same data as holotype, used for SEM.
Etymology. Named after my nephew, Kamiel Fannes, who has a special bond with spiders.
Diagnosis. The large eyes (Figs. 5 E, F, 9D) separate this species from all other known Antoonops species. Males can also be recognized by their abdomen, which has a ventral depression (Fig. 4 E, arrowhead) and only a slight dorsal constriction (Fig. 4 E, arrow). Females can be recognized by their external genitalia, which consist of a small posterior element and an elongated, indistinct anterior element (Figs. 9 H, 17C).
Description. Male (Figs. 4–8, 17A, B). TL 1.28. Habitus as in Fig. 4 A. Cephalothorax: Carapace orangebrown, with three short, dark-red stripes (a dorsal stripe flanked by two upper stripes; Fig. 17A), completely covered by microsculpture, anterolateral corners with strongly sclerotized, triangular extension, thorax without depressions or radiating rows of pits, posterolateral edge without pits, posterior margin not bulging below posterior rim, posterolateral surface without spikes; lateral margin straight, rebordered (Figs. 4 B, D, 5A–C). Clypeus straight in lateral view, high, ALE separated from edge of carapace by their radius or more, median projection absent (Fig. 5 E). Six eyes, large; ALE-ALE: separated by their radius to diameter; ALE-PLE: separated by less than PLE radius; PME-PME: almost touching; PLE-PME: separated by less than PME radius; posterior eye row straight in dorsal view (Fig. 5 E, F). Sternum longer than wide, orange-brown, fused to carapace, surface smooth, median concavity absent, with radial furrows between coxae I-II, II-III, III-IV, without posterior hump, setae abundant, without hair tufts (Figs. 4 C, 5D, 6A). Pleural flaps present. Chelicerae yellow-brown, anterior face of paturon unmodified, with sparse setae (Fig. 5 C); posterior surface of paturon with 2-3 short spines and row of five long, medially directed setae (Fig. 6 B); fangs without tooth-like projections, shape normal, without prominent basal process, tip unmodified (Fig. 6 B). Endites enlarged, posteromedian part bulging (Fig. 6 C); ventral surface heavily sclerotized except for diagonal band (Fig. 4 C); median surface with a pocket; anterior edge of pocket continuing into median projection (Fig. 6 E); median projection short, hook-shaped, directed posteriorly (Fig. 6 D–F); P1 projection absent. Labium much more heavily sclerotized than sternum, much wider than long (Fig. 4 C). Pedicel: With one dorsal and one ventral sclerite; dorsal sclerite flat, posteriorly drawn out into a point, not fused to prosoma, without special modifications; ventral sclerite U-shaped, covering ventral and lateral sides of pedicel, anteriorly fused to prosoma, ventral surface forming a large process (Fig. 7 A). Abdomen: Without long posterior extension, with ventral depression (Figs. 4 E, 7B, arrowhead) and slight dorsal constriction (Fig. 4 E, arrow). Book lung covers red-brown, large, ovoid, without setae, anterolateral edge unmodified (Fig. 4 H). Posterior spiracles not connected by groove. Pedicel tube short, without triangular extensions, without fringe of setae (Fig. 7 E); scutopedicel region without ridges or denticles, with small oval glands, plumose hairs absent, matted setae on anterior ventral abdomen in pedicel area absent. DS strongly sclerotized, covering full length of abdomen, no soft tissue visible from above, color pattern as in Fig. 4 F, not fused to ES, anterior half without projecting denticles, surface smooth except anterior third which has granular microsculpture (Fig. 7 C, F, G). ES strongly sclerotized, yelloworange, with dark-red dorsal edge, surrounding pedicel, small lateral sclerites absent. PES strongly sclerotized, yellow-orange, relatively long, leaving less than 1/4 of abdomen length uncovered, fused to ES (Figs. 4 G, 7D). Lateral apodemes visible through integument (Fig. 4 H). Spinneret scutum present, incomplete ring, with fringe of needle-like setae. Anal scutum present, very weakly sclerotized. Interscutal membrane with setae. Colulus small, sclerotized, with two setae (Fig. 8 A). ALS bisegmented, with one major ampullate gland spigot and three piriform gland spigots; PMS unisegmented, with single spigot; PLS bisegmented, with three spigots. Legs: Base color white-yellow, femora I-IV with distal darkening, tibia IV and metatarsus IV with basal darkening; without spines; femur IV not thickened, same size as femora I-III, patella plus tibia I shorter than carapace; tibia I without dorsal row of ridges, tibia III with group of specialized setae on ventral apex. Tarsal claws examined with SEM; superior claws I-II with 3-4 large, proximally situated teeth on lateral surfaces, about 10 small, distally situated teeth on median surfaces; superior claws III-IV with 2-4 large, proximally situated teeth on lateral surfaces, about 3 small, distally situated teeth on median surfaces; inferior claw absent. Trichobothria examined with SEM; each leg with four dorsal trichobothria: one on proximal tibia, two on distal tibia, one on distal metatarsus (Fig. 8 B); bothrium with ridges, aperture internal texture grate-like. Tarsal organ exposed, legs I-II with three receptors, legs III-IV with two receptors. Genitalia: Epigastric region with sperm pore small, elliptical, wider than long, situated at level of posterior spiracles (Fig. 17 B). Male palp not strongly sclerotized, proximal segments yellow-brown, right and left palps symmetrical; trochanter unmodified; femur two or more times as long as trochanter, attaching to patella basally; patella shorter than femur, not enlarged, without prolateral row of ridges, setae unmodified; tibia as long as patella, with three dorsal trichobothria; cymbium yellow-brown, fused with bulb but with clearly defined seam between, extending beyond distal tip of bulb, with distal patch of setae; bulb yellow-brown, shorter than cymbium, with distal embolus and conductor; embolus short, tube-shaped, its tip bent upwards; conductor slender, situated prolaterally of embolus (Fig. 8 C–F).
Female (Figs. 9, 17 C). TL 1.36. As in male except as noted. Habitus as in Fig. 9 A. Cephalothorax: Carapace without stripes, shape as in Fig. 9 B, D. Clypeus low, ALE separated from edge of carapace by less than their radius. Chelicerae, endites and labium brown. Endites same as sternum in sclerotization, unmodified (Fig. 9 E). Labium same as sternum in sclerotization, wider than long (Fig. 9 E). Female palp yellow-brown, without spines; femur approximately twice as long as patella; patella about as long as tibia; tarsus not expanded, twice as long as tibia.
Abdomen: Without ventral depression. Book lung covers yellow-orange (Fig. 9 H). ES without dark-red dorsal edge. PES not fused to ES, short, leaving about half of abdomen length uncovered (Fig. 9 G). Spigots not examined. Legs: Trichobothria examined with stereo microscope; number and position as in male. Tarsal organs and claws not examined in detail. Genitalia: External genitalia as in Figs. 9 H, 17C, with an elongated, indistinct anterior element and a small, dark-red posterior element (the anterior element is probably the genital duct; the posterior element may be the copulatory opening).
Distribution. Known only from the type locality (Fig. 1).
