description: Fuchibotulus kigelia sp. n.
Figs 53–55, 58, 67–71
Etymology:This species is named after the African sausage tree, Kigelia africana (Lam.) Benth. (Bignoniaceae); the name refers to the elongate shape of the spermathecae. The epithet is a noun in apposition.
Diagnosis: Males can be recognised by the embolus, which projects beyond the retrolateral margin of the cymbium, and the simple subtriangular RTA; females can be recognised by the long ST I, which extend posteriorly beyond the anterior margins of the copulatory openings.
Description:
Male.
Measurements: CL 1.40–1.67, CW 1.12–1.40, AL 1.45–1.80, AW 1.17–1.35, TL 2.80– 3.20, FL 0.10–0.12, SL 0.71–0.87, SW 0.63–0.73, AME–AME 0.06, AME–ALE 0.02, ALE–ALE 0.29, PME–PME 0.10, PME–PLE 0.13, PLE–PLE 0.54. Length of leg segments: I 1.21+0.63+1.03+0.81+0.47=4.15; II 1.02+0.53+0.77+0.68+0.43=3.43; III 0.80+0.46+0.53+0.64+0.29=2.72; IV 1.07+0.53+0.89+0.99+0.33=3.81.
Carapace, including eye region, deep orange, slightly darker near margins (Fig. 53); carapace slightly rounded anteriorly with highest point at 1/3 its length, flat dorsally, sloping very slightly to 4/5 its length, last fifth with steep decline; surface coarsely granular, covered in very short fine setae; fovea short, distinct, slightly thickened, at 3/4 carapace length. Eyes surrounded by black rings; AER procurved, eyes subequal; clypeus height equal to 1.25× AME diameter; AME separated by slightly less than 0.66× their diameter; AME separated from ALE by slightly less than 0.25× AME diameter; PER strongly recurved, median eyes slightly larger than laterals; PME separated by distance equal to their diameter; PME separated from PLE by 1.5× PME diameter. Chelicerae orange; anterior surface granular, with scattered long and short fine setae; promargin with three closely spaced teeth, median tooth largest, proximal tooth smallest; retromargin with three teeth on single base, proximal tooth large, median and distal teeth flat, only projecting slightly. Sternum bright orange, darker along border; surface smooth, with scattered short fine setae.Abdomen: pale grey throughout, without dorsal chevron markings; oval, distinctly notched anteriorly, tapering posteriorly, broadest at half its length, longer than wide (Fig. 53); dorsal scutum absent; surface finely granulate, covered in short stout setae anteriorly, becoming finer towards posterior; two pairs of large elongate dorsal sigilla present, first pair at 1/3 abdomen length, second pair near midpoint; each sigillum split transversely in two in some specimens; several pairs of tiny oval or elongate intermediary sclerites posterior to each pair; venter with small oval sclerites running in two paired lines from epigastric fold to spinnerets; small broad inframamillary sclerite present. Legs I to IV deep yellow-brown, femora slightly darker distally, tarsi slightly paler; weakly developed scopulae on metatarsi and tarsi, remaining leg segments covered in short fine setae; leg spines and cusps absent. Male palp with small triangular retrolateral tibial apophysis with sharp tip, and small secondary tooth-like dorsal apophysis (Figs 58, 67, 68); embolus fine, originating prolaterally on tegulum, curling around tegulum, ending in sharp tip projecting beyond retrolateral margin of cymbium; conductor narrow and membranous, reaching embolus tip (Fig. 67).

Carapace, including eye region, deep orange, orange-brown laterally (Fig. 54); carapace slightly rounded anteriorly with highest point at 1/3 its length, flat dorsally, sloping very slightly to 4/5 its length, last fifth with steep decline; surface coarsely granular, covered in very short fine setae; fovea short, distinct, slightly thickened, at 3/4 carapace length. Eyes surrounded by black rings; AER procurved, lateral eyes slightly larger than medians; clypeus height equal to AME diameter; AME separated by 0.5× their diameter; AME separated from ALE by approx. 1/8× AME diameter; PER strongly recurved, eyes subequal; PME separated by distance approx. equal to their diameter; PME separated from PLE by approx. 1.33× PME diameter. Chelicerae orange; anterior surface granular, with scattered short and long fine setae; promargin with three teeth, median tooth largest, proximal tooth smallest; median and distal teeth closest together; retromargin with three subequal teeth sharing single base. Sternum orange, dark orangebrown along border; surface smooth, covered in short fine setae. Abdomen: pale grey throughout, with very faint grey indistinct dorsal chevron markings; oval, distinctly notched anteriorly, tapering posteriorly, broadest at half its length, longer than wide (Fig. 54); dorsal scutum absent; surface finely granulate, covered in short stout setae anteriorly, becoming finer towards posterior; one pair of elongate sigilla present at 1/3 abdomen length, with several pairs of small intermediate sclerites near midpoint of abdomen (Fig. 55); venter with small oval sclerites, running in two paired lines from epigastric fold to spinnerets; small inframammilary sclerite present.
