Description. Male. Head (eyes included) as wide as, or slightly wider than, pronotum; forehead wide: distance between eyes more than three times the eyes width. Head length/width ratio approximately 1, looking at the insect head placed horizontally. Antennae rather short, slightly and gradually widened from base to apex; articles 3, 4, 5 narrow (but 5 variable); 6, 7, 8 shorter than 4, 5; 9, 10 approximately globular. Pronotum slightly wider than long (transverse), its maximum width in the middle, moderately narrowed forwards and backwards; anterior margin wider than posterior one; pronotum surface deeply puncturated but smooth and bright between the punctures. Elytra parallel-sided; feebly bordered; jointly rounded at apex; apices slightly divergent; apical angle well defined, rectangular. Body covered with short, pale greenish to whitish, scale like setae (as in the other Danacea) which, in this species, are rather sparse; pronotal setae on disc nearly all parallel and directed forwards, on the anterior margin more or less converging towards a point in the middle. Elytra surface often “decorated” with one or two symmetrical spots, and/or a posterior transversal band, apparently bare (actually covered with hardly visible, sparse, pale brown setae). Integuments dark green, bright with metallic glare: dorsal surface resulting colour (hairs plus integuments) grey-green; labium and mandibles yellow; legs entirely yellow; antennae yellow with just the tip of 11 th article darkened; palpi yellow with apical half of last article darkened. Median lobe as in Figures 2 A, 2 B, 2 C. Internal sac very long, its basal part (namely the part visible inside the median lobe apical half) fitted with two weakly sclerified lamellae (Figures 2 C, 2 D); its median part (which extends outside the median lobe base) showing a tiny granulation; apical orifice not clearly detectable. Spicular fork (Figure 2 E) branches rather thin. Female. Similar to male but eyes more flattened; elytra clearly widened in apical half and “decorated” more frequently than in males. Dimensions in mm: Males Females Differential diagnosis. Danacea hierena n. sp. belongs to the first group Danacea (Danacea) (Schilsky 1897, Liberti 1989) which includes the species where the discal scale-like setae on pronotum are all parallel and directed forward. It is very similar to Danacea trinacriae Liberti, 1979 and Danacea zingara Liberti & Baviera, 2004. These two species, widespread and sometimes common or very common in the Trapani province, are absent from the Egadi Archipelago: their ranges do not overlap with that of D. hierena. The main differences are summarized in the table below (the colour characters of palpi and antennae often being rather variable). D. hierena n. sp. D. trinacriae Liberti D. zingara Liberti & Baviera Median lobe As in Figs 2 A, 2 B, 2 C. Median As in Liberti & Baviera (2004: As in Liberti & Baviera (2004: lobe apical part longer, bent Fig 8). Median lobe apical part Figs 1 –3). Median lobe apical ventrally. shorter, weakly bent dorsally. part shorter, bent dorsally. Internal sac As in Figs 2 C, 2 D. Lamellae As in Liberti & Baviera (2004: As in Liberti & Baviera (2004: weakly sclerified, wide, rather Fig 8). Lamellae sclerified, Figs 1 –3). Lamellae sclerified, short. thin, rather short. wide, rather long, nearly tubular. The quotations of D. trinacriae for Marettimo and Levanzo Islands, reported in Liberti & Baviera (2004), must be referred to D. hierena n. sp. Etymology. The name derives from Hiera, an ancient name of Marettimo. Ecology. The adults of this species have been collected in April and May on several kinds of flowers, where they feed on pollen: on Favignana mostly on umbelliferous flowers (Magydaris sp.); on Marettimo on the abundant blossoming Euphorbia bushes.Published as part of Baviera, Cosimo & Liberti, Gianfranco, 2010, Dasytidae of the Egadi Archipelago (Coleoptera, Cleroidea) with description of Danacea hierena n. sp., pp. 49-57 in Zootaxa 2351 on pages 50-52, DOI: 10.5281/zenodo.19346

[red printed] Diagnosis. A small brownish-red Solariola, with elytral surface with deep and dense punctures, elytral setae of the same length of pronotal ones, strongly inclined towards elytral surface (angle with elytral surface 0–15 °), antennae with all funicular segments wider than long. Holotype description. Body length 2.72 mm, maximum width of elytra 0.85 mm. Rostrum almost as wide as long, confusedly and deeply wrinkled, with narrow furrow, subparallel rostral carinae very slightly arched and closest at base. Antennae with scape less than seven times longer than wide, slightly curved at proximal third, regularly thickened from base to apex, funicle short, less than seven times longer than wide, segment 1 of funicle clavate, slightly less than two times longer than wide, segment 2 shorter and about 2 times longer than wide, 3 to 7 and wider than long, 7 strongly transverse (width/length ratio 1.15); club three-segmented, oval, less than twice long its width (width/length ratio 0.63), densely covered with short setae. Prothorax almost as long as wide (width/ length ratio 0.93), strongly convex, widest at middle, disc with large deep punctures merged with smaller shallower ones which bear long recumbent seta, these pairs of points are more distant from each other on disc than on sides, their interspaces smooth, strongly inclined centripetal setae inserted in smaller punctures are on average less than 3 times the average diameter of the larger points. Elytra oblong elongate, oval, narrower at base than maximum width of prothorax, length twice their overall width (width/length ratio 0.52), humeri obliquely rounded, subparallel sides regularly convergent to apex, scarcely and very regularly curved, maximum width at mid length, narrowing apically. Punctures of striae robust, large, deep, almost square, each bearing inside a short seta, slightly less in length than average diameter (≤ 0.03 mm) of points. Interstriae flat, clearly demarcated by points of striae, minutely punctured, points lower in number than those of striae, each bearing a fairly long (average 0.08 mm) almost curved, laterally flattened and not much raised, often strongly inclined towards elytral surface (angle with elytral surface 0–15 °) seta, some of those setae on elytral apex are spatulate and recumbent on elytral surface. Legs thin, elongate, with rather long flattened setae, half-lifted on tarsi. Tibiae slightly curved in side view, protibiae more widely curved and with setae and very small tooth-like tubercles on inner edge, tubercles more evident on meso- and metatibiae. Apex of tibiae strongly mucronate and with a fringe of thick golden setae. Femora edentate, clubbed in the middle and narrowed at apex. Aedeagus long, slightly curved, sclerotisation of sides broadened on basal half, sides parallel from base to middle, and thereafter suddenly widened, with slightly arched apex regularly curved; long lamella triangular shaped, covered on sides, medially raised.

Spermatheca broad with very short nodulus and cornu, arched, distally constricted. Other males slightly differ only by size, while females differ by the usual sexual dimorphism observed in others species. Etymology. The new species is named after Carlo Pesarini, former curator of the Natural History Museum of Milan, for his great help in the course of many years of research on Sicilian Curculionidae. Distribution. Peloritani Mounts, Malabotta Forest (Fig. 12). Affinities. Morphologically very similar to S. hirtula because of pronotal and elytral punctuation and short funicle, differing from it by inclination of elytral setae, shape of funicular segments and apex of aedeagus. Also related to S. vitalei from which differs by inclination of elytral setae, aedeagus and spermatheca shape, and deeper pronotal and elytral punctuation. Ecology. Osella et al. (2004, sub S. vitalei) consider this species a typical humid and sub-humid Mediterranean forest dweller, thus a relict species related to palaeoclimates characteristic of the tertiary Mediterranean forests. Adults of S. pesarinii have been sifted from the soil or, in number, hand collected under stones in April (Colacurcio and Paladini, personal communication), of an old Quercus forest growing on a moist limestone soil.Published as part of Baviera, Cosimo, 2015, A review of the genus Solariola Flach, 1908 (Coleoptera: Curculionidae: Entiminae, Peritelini), pp. 401-430 in Zootaxa 3920 (3) on pages 417-419, DOI: 10.11646/zootaxa.3920.3.1, http://zenodo.org/record/24075

Legs quite short and robust; femora clubbed, edentate; tibiae short, almost straight, external margin of protibiae blunt, internal one devoid of spines; protarsi short and robust, third joint shortly bilobed, onychium curved, claws short and fused at base. Spiculum ventrale: see Fig. 87; spermatheca: see Fig. 101. Paratypes: Only females. Specimens of Castiglione are bigger (mm 4.20 –5.00) of Malabotta ones (mm 3.70– 4.20). No significant differences were observed between the holotype and paratypes. Length: 3.70 –5.00 mm. Distribution: Northern and central Sicily. Etymology: Named after the hedgehog (Erinaceus europaeus L., 1758) in reference to the erect thin setae on the dorsal surface. Ecology: This species prefers cool shadowy places, and has been found sifting under Fagus sp., Olea sp., Rubus sp., Quercus sp., Fraxinus sp., Smilax sp. Adults occur in spring and/or autumn, according to the elevation, with diapause in summer or in winter. Pseudomeira erinacea is a parthenogenetic species collected at Castiglione di Sicily together with P. vitalei; at Malabotta, Marineo and Ficuzza with Heteromeira neapolitana; at Pioppo with Dolichomeira dubia Pierotti & Bellò, 1994 and at Castelvetrano with Dolichomeira sp.. Reproduction: Parthenogenetic. Notes: Only detailed morphological, ecological and molecular studies have allowed for the recognition of this cryptic species, incorrectly indicated from some localities as P. s o l a r i i by Péricart (1963) and Pierotti & Bellò (1994).Published as part of Bellò, Cesare & Baviera, Cosimo, 2011, On the Sicilian species of Pseudomeira Stierlin (Coleoptera: Curculionidae: Entiminae), pp. 35-68 in Zootaxa 3100 on pages 45-46, DOI: 10.5281/zenodo.20487

Known from Nebrodi Mountains at 50–400 meters a.s.l.. Ecology and Phenology. Collected by Berlese and Winkler extractors from soil obtained sifting the leaf litter on clay soil, of an olive grove in spring and automn, at 50–400 meters. Collections in the summer season gave negative results. Main soil type. Vertic-Cambisol (European Soil Data Centre; Panagos et al. 2012). Reproduction. Parthenogenetic. Species known from fifty females. Chorological relationships. Sympatric at San Fratello with Pseudomeira nebrodensis Pierotti (2009) while at San Marco d’ Alunzio with Pseudomeira solarii (Péricart, 1963). Systematic Note. In the San Fratello locality (Sicily, Monti Nebrodi) two sympatric species live: one parthenogenetic (belonging to Dodomeira gen. n.) and one amphigonic (belonging to Pseudomeira Stierlin, 1881). In a nomenclature note Pierotti (2012) established that the name P. nebrodensis must be preserved for the holotype male of the amphigonic species. He re-describes the two species, using the new name P. confusa for the parthenogenetic species and P. nebrodensis for the amphigonic.Published as part of Baviera, Cosimo, 2017, A taxonomic monograph of the genus Dodomeira Bellò & Baviera, a new genus of Peritelini from Sicily (Coleoptera: Curculionidae: Entiminae), pp. 1-138 in Zootaxa 4334 (1) on pages 51-53, DOI: 10.11646/zootaxa.4334.1.1, http://zenodo.org/record/100986

Description.Total length (from apical margin of labrum to tip of elytra): mm 2.48–2.51 ♂♂, 2.52–2.62 ♀♀. Micropterous; black, with legs, mandibles, palpi and antennae rufo-testaceous. Teguments smooth, shiny, glabrous, with microsculpture hardly visible on disk of pronotum and elytra, more evident on elytra, consisting of very thin transversal meshes. Head small and elongated; temples long (as long as the eyes), prominent and narrowing on neck; frontal furrows deep and complete; eyes not very large and flat, markedly longer than genae; two supraorbital setae on each side and on lines not converging backwards. Antennae narrow and short, hardly reaching the elytral base, with the apical segment slightly longer than penultimate. Pronotum strongly transverse (PW/PL = 1.27–1.37 ♂♂; 1.30–1.40 ♀♀), convex, largest at the anterior fourth. Sides arcuate throughout their length, sinuate before the hind angles, which are obtuse but prominent; front angles not projecting forwards; basal peduncle prominent, not bordered at the posterior edge; lateral keel relatively narrow; median furrow superficial; basal impressions small and superficial, adjoining the terminal part of the lateral keel. Two lateral setae on each side, the anterior one just before the largest point, the posterior markedly advanced with respect to basal angle. Elytra oval, moderately slender, convex; lateral keel broad, flattened, with salient and almost reflex borders; shoulders regularly rounded, not angulate, not prominent; external elytral striae completely obsolete, striae 1–3 hardly visible in the basal part, completely obsolete in the apical one; sutural stria hardly visible. Basal striole absent, recurrent stria and apical carina scarcely evident. Chaetotaxy: juxtascutellar pore present, two discal pores relatively large, fovea-like, the first one at basal fifth, the second one just after the middle; umbilicate series regular, humeral group with the pores 2 nd to 4 th almost equidistant, 1 st and 2 nd closer; apical group with the anterior pore at the level of the 8 th pore of the umbilicate series; exterior pore of the apical group lacking. Legs short and slender; protibial furrow complete but superficial; metatibiae straight; in ♂ two first protarsomeres asymmetrically dilated. Aedeagus (fig. 2) robust, elongate. Median lobe, in lateral view, markedly and sharply curved at base, subrectilinear in the central part, bent upwards in the apical one, which is subtriangular. Basal bulb normal, sagittal carina long and well developed. Inner sac provided with a long scaly patch. Styles long, reaching the apical third of the median lobe, each provided with 4 long distal setae. Etymology. It is a pleasure for us to dedicate this new species to one of its collectors, our friend and colleague Giuseppe Osella, a specialist of Coleoptera Curculionoidea, as a token of our esteem for his valuable contribution to the knowledge of the South-American beetles. Distribution and ecology. At present O. osellai n. sp. is only known from the type locality, Cangahua (Ecuador, Pichincha province), where it was collected by sifting the soil collected under stones and bunch- or tussock-forming grasses typically occurring in the grass-páramos of Ecuador from about 3400 to over 4000 m (Moret, 2009) (fig. 8).Published as part of Giachino, Pier Mauro, Allegro, Gianni & Baviera, Cosimo, 2014, Two new species of Oxytrechus Jeannel, 1927 from Ecuador (Coleoptera, Carabidae), pp. 144-150 in Zootaxa 3895 (1) on pages 145-148, DOI: 10.11646/zootaxa.3895.1.10, http://zenodo.org/record/22879
Additive normal tempered stable processes for equity derivatives and power-law scaling
No full textWe introduce a simple additive process for equity index derivatives. The model generalizes Lévy Normal Tempered Stable processes (e.g. NIG and VG) with time-dependent parameters. It accurately fits the equity index volatility surfaces in the whole time range of quoted instruments, including options with small time-horizon (days) and long time-horizon (years). We introduce the model via its characteristic function. This allows using classical Fourier pricing techniques. We discuss the calibration issues in detail and we show that, in terms of mean squared error, calibration is on average two orders of magnitude better than both Lévy and Sato processes alternatives. We show that even if the model loses the classical stationarity property of Lévy processes, it presents interesting scaling properties for the calibrated parameters

Synthetic forwards and cost of funding in the equity derivative market
No full textThis study introduces a new technique to recover the implicit discount factor in the derivative market using only European put and call prices: this discount is grounded in actual transactions in active markets. Moreover, this study identifies the implied cost of funding, over OIS, of major market players. Does a liquid equity market allow arbitrage? The key idea is that the (unique) forward contract -built using the put-call parity relation- contains information about the market discount factor: by no-arbitrage conditions we identify the implicit interest rate such that the forward contract value does not depend on the strike. The procedure is applied to options on S&P 500 and EURO STOXX 50 indices. There is statistical evidence that, in the EURO STOXX 50 market, the implicit interest rate curve coincides with the EUR OIS one, while, in the S&P 500 market, a cost of funding of, on average, 34 basis points is added on top of the USD OIS curve
