Zannicranaus new genus

Etymology. From Zanni, one of the masquerade stereotypes of Italian Commedia dell’arte, notable for having a big nose (which strongly resembles the spine in frontal hump which characterizes the genus) + pre-existing generic name Cranaus . Gender masculine.

Diagnosis. Outline of dorsal scutum in dorsal view guitar-shaped (widest part clearly displaced posteriorly) either with ( Z. morlacus, Fig. 23) or without defined coda ( Z. monoclonius, Fig. 3). Frontal hump of carapace with huge spine bent frontwards (Figs. 2, 22). Cheliceral bulla of male with mid-posterior dorsal erect spine (Figs. 2, 22). Tibia-tarsus of pedipalpus rotated ectally (Figs. 11, 30); femur-tibia with dorsal rounded tubercles (Figs. 7–8, 13, 26–27, 32). Femur with dorso-apical short spine (Figs. 8, 27), none of pedipalpal articles specially elongate. Male calcaneus I twice as long as astragalus and thickened. Coxa IV of male with pair of ventro-distal paramedian acuminate tubercles (Figs. 2, 22). Femur IV of male from substraight (Fig. 21) to slightly sinuous (Fig. 1) and with few weak spines. Tarsi III–IV with weak scopula, tarsal claws unpectinated. Tarsal counts, male: 7(3)/12-16(3)/7-9/ 8-9, female: 6(3)/13(3)/8/9. Truncus penis either straight ( Z. morlacus, Fig. 33) or clearly angled ( Z. monoclonius, Fig. 14). Ventral plate of penis strongly angled against truncus (Figs. 14, 33), with wide and shallow V-cleft (Figs. 15–16, 34–35), either guitar-shaped ( Z. monoclonius, Fig. 15) or subrectangular ( Z. morlacus, Fig. 34), and with two lateral patches of scale-setae on ventral surface (Figs. 15, 34). Glans sac very long, fanfold, with small conical dorsal process (Figs. 14, 16, 33, 38). Stylus either straight, growing thinner distally ( Z. monoclonius, Fig. 20) or uniformly thin, sinuous ( Z. morlacus, Fig. 38). Stylus head either simple, elongate-erythrocyte-shaped ( Z. morlacus, Figs. 36–37) or complex, with 2 stylar distally-villose caps ( Z. monoclonius): dorsal horseshoe-shaped (Figs. 19–20) and ventral elongate tapering foliaceous (Figs. 17–18, 20). Sexual dimorphism evident in shape of carapace and basichelicerite (compare Figs. 3 and 6), much stronger in male (females known only for Z. monoclonius).
