Fuchibotulus

description: Genus Fuchibotulus gen. n.
Etymology: The name is a combination of Fuchiba, a genus to which these spiders are related, and the Latin botulus (sausage), that refers to the sausage-shaped ST II of the female. Gender masculine.
Type species: Fuchibotulus bicornis sp. n.
Diagnosis: The carapace shape is evenly high and flat dorsally, with a sharp decline in the last fifth, and has a strongly tuberculate surface texture (Figs 50, 51, 53, 54). The abdomen is notched anteriorly and has distinct dorsal sigillae with several pairs of tiny intermediate sclerites among them (Figs 52, 55). The legs lack spines and ventral cusps, and are weakly scopulate. Males have a needle-like embolus originating prolaterally and curving retrolaterally around the tegulum, accompanied by a narrow membranous conductor (Fig. 56); the palpal tibia has a larger single or bifid distal retrolateral apophysis and a small tooth-like proximal retrolateral dorsal apophysis (Figs 57, 58); females have a narrow median epigynal hood and strongly twisted entrance ducts leading to long, sausage-shaped ST II, with corresponding twisted ducts leading from ST II to the small posterior ST I.
Description: Small spiders, 2.80–3.55 mm long; carapace red, surface strongly granulate; abdomen pale grey with darker dorsal chevron marking; AER procurved, clypeus height equal to or slightly larger than AME diameter; AME slightly smaller than ALE, or eyes subequal; AME closer to ALE than to each other; PER strongly recurved; PME slightly larger than PLE, or eyes subequal; PME closer to each other than to PLE; chilum single, triangular, tapring distally; cheliceral promargin and retromargin with three teeth each, retromarginal teeth often on single base; labium trapezoidal, posterior width equal to length; endites straight laterally with distinct serrula; carapace broadly oval, widest at midpoint, eye region smoothly connected to thoracic region; carapace with slight depression anterior to fovea, posterior margin slightly concave; pleural bars isolated; sternum shield-shaped; precoxal triangles present; intercoxal sclerites present between coxae I and II, II and III, and III and IV; legs I slightly more strongly built than others in males; legs without spines or ventral cusps, metatarsi and tarsi weakly scopulate, metatarsi III and IV with terminal preening brush; leg formula 1423 ♂, 4123 ♀; abdomen oval, distinctly notched anteriorly, tapering posteriorly; dorsal scutum absent in both sexes; dorsal sigilla present, with several intermediate sclerites between them; venter with paired tiny sclerites running from epigastric fold to spinnerets; small inframamillary sclerite present; male palp with subtriangular RTA, sometimes split distally, and small tooth-like dorsal apophysis; tegulum oval, embolus needle-like, originating prolaterally, directed retrolaterally along distal margin of tegulum, accompanied by narrow membranous conductor; female epigyne with narrow median epigynal hood, copulatory openings medially, entrance ducts strongly twisted, ST II long and sausage-like, directed posteriorly; duct leading from ST II to ST I twisted around entrance ducts; ST I small and oval, posterolaterally situated.
Species included: F. bicornis and F. kigelia (both new).
