Horns strong, strongly upturned and triangular in cross section, very separated on base from each other and apically acute. Frons with a transversal elevated angled process, strongly punctured on apex and posteriorly, anteriorly with sparse small punctures (fig. 2). Eye canthus with strong coalescent punctures, basally the obtuse angle with sparse small setae (fig. 3). Pronotum bordered all around, very convex and rounded laterally, densely punctured, punctures coalescent anteriorly and on disc. Anteriorly with an elevation with two microgranulated flattened and rounded tubercles, directed forward. Elytral surface completely covered by irregular punctures, with some coalescent punctures and with 5 lines of punctures, humeral punctures smaller than in the remaining elytral disc. Pygidium surface rugulose with very small setae, disc with weak coalescent punctures, basal margin concave. In lateral view, surface weakly convex.

Left mandible with a sub triangular flattened internal expansion with 7 conjoined rounded teeth, the basal 4 more distinct; base of expansion with a convex tooth; internal basal face carinate; carina at middle with a columnar vertical trituberculate process; basal tooth somewhat rounded, dorsally carinate. Right mandible with 6 conjoined rounded teeth, increasing in size to base; apical third simple, more inwardly curved; basal tooth bifurcate with apical tooth acute and basal tooth rounded, dorsally carinate; carina extending until sixth internal tooth. Mentum trapezoidal, transverse, moderately densely punctate; punctures moderate. Antennae with scape somewhat backwards curved; flat dorsally and with no dorsal carina. Pronotum: Surface opaque, punctate; punctures fine. Anterior angles acute, reaching posterior side of temporal process; lateral angles widely rounded; posteriorly with right angles. Disc weakly depressed, flat. Lateral and posterior margins distinct; anterior margin incomplete at median pronotal third, anteriorly with yellowish-white band of setae. Elytra: Integument surface smooth medially on disc. Elytra from suture to lateral side with 4 distinct striae present, then completely and densely punctate; punctures fine to large, each with a scalelike, centered seta. First and second interstriae very finely punctate; punctures larger on elytral declivity. Third and fourth interstriae almost smooth on disc, becoming punctate anteriorly and posteriorly; punctures fine, moderate, denser on elytral declivity. Humerus weakly angulate. Epipleuron flattened, especially at middle and with elongate yellowish-white setae; posterior margin densely setose.

Internal margin rounded near base. Mesotibiae with 1 spine-like tooth, just after middle; ventral mesotibial spur with apex slightly incurved. Metatibiae with 1 small tooth after middle, tooth almost imperceptible; apex in dorsal view acute. Genitalia: Genital capsule simple. Aedeagus symmetric (Fig. 36). Basal piece 1.5 times longer than parameres length. Parameres distally rounded, with scattered setae; median lobe elongate, apex wider than base, with a narrow emargination medially to the end of the first third; laterally less sclerotized. Everted internal sac shorter than parameres and basal piece length combined, almost membranous, and with a paired internal strap-like sclerite; sclerite ending at the apex of the first half; apex extremely dilated, darker than the remaining internal sac; gonopore large, as wide as median lobe width. Description, allotype female (Fig. 10). Length: 18.7 mm. Width: 5.1 mm. Differing from the holotype male in the following characters. Head: Shorter, quadrate; surface shiny, completely and densely punctate; punctures moderate, being finer at vertex; temporal process absent; frons slightly declivous, flat. Mandibles shorter than head, asymmetry less evident (apparently symmetric); dorsal furrow reaching apex, basally wider and deeper; internal face with 1 strong and rounded tooth at dorsal margin and 2 smaller teeth at ventral margin. Pronotum: Shape less transverse; surface more punctate, especially at lateral and posterior margins; punctures moderate. Elytra: Epipleuron less setose with shorter setae. Legs: Mesotibiae with 2 proximal smaller teeth. Metatibiae with 1 external spine-like tooth; apex in dorsal view dentate. Description, variation in male and female paratypes. Males. Length: 16.0–20.0 mm. Width: 5.8–7.3 mm. The males paratype do not differ significantly from the holotype except by the reduction in the number of conjoined teeth in mandibles. Females. Length: 15.0–18.5 mm. Width: 5.0–5.7 mm. The female paratypes do not differ significantly from the allotype. Epithet. The specific epithet is tribute to the largest indigenous group, the Asháninka, who inhabit the Junín region, and who are the main group responsible for the forest preservation at the place where the new species was found. Remarks. This species is very similar to I. zugeri, with which it has been confused. The specimens used in the description were labeled as Incadorcus zugeri “black form”, but they are readily distinguished by the elytral punctures and color. The aedeagus of this species is also unique within the genus, with the apex of the everted internal sac extremely differentiated apically. Incadorcus ashaninka and I. zugeri are the largest members of the genus and have disjunct ranges, the new species with the more southerly distribution.Published as part of Grossi, Paschoal Coelho, 2011, Review of Incadorcus Arnaud & Bomans with the description of three new species from the Yungas of Peru and Bolivia (Coleoptera: Lucanidae: Lucaninae), pp. 1-14 in Zootaxa 2750 on pages 4-6, DOI: 10.5281/zenodo.20279

No full textStatistical selection of perimeter-area models for patch mosaics in multiscale landscape analysis
No full textThis paper presents a statistical method for detecting distinct scales of pattern for mosaics of irregular patches, by means of perimeter-area relationships. Krummel et al. (1987) were the first to develop a method for detecting different scaling domains in a landscape of irregular patches, but this method requires investigator judgment and is not completely satisfying. Grossi et al. (2001) suggested a modification of Krummel’s method in order to detect objectively the change points between different scaling domains. Their procedure is based on the selection of the best piecewise linear regression model using a set of statistical tests. Even though the change points were estimated, the null distribution used for testing purposes were those appropriate for known change points. The present paper investigates the effect that estimating the change points has on the underlying distribution theory. The procedure we suggest is based on the selection of the best piecewise linear regression model using a likelihood ratio (LR) test. Each segment of the piecewise linear model corresponds to fractal domain. Breakpoints between different segments are unknown, so the piecewise linear models are non-linear. In this case, the frequency distribution of the LR statistic cannot be approximated by a chi-squared distribution. Instead, Monte Carlo simulation is used to obtain an empirical null distribution of the LR statistic. The suggested method is applied to three patch types (CORINE biotopes) located in the Val Baganza watershed of Italy
Nuove tecniche per la selezione degli indici di bilancio nel monitoraggio delle imprese
No full textIn questo lavoro viene suggerita una nuova soluzione al problema della scelta di un numero limitato di indici di bilancio da utilizzare per la classificazione delle aziende. La soluzione proposta si avvale, quali strumenti metodologici, di due procedure per la selezione delle variabili introdotte recentemente in letteratura: gli alberi decisionali secondo la metodologia QUEST (Loh e Shih, 1997), e la tecnica del grafico a stalagmiti (Grossi et al., 1999). L'interesse del ricorso a tali approcci è imputabile principalmente al loro carattere essenzialmente non parametrico, importante dal punto di vista pratico perchè evita il ricorso a
