The resolution of whole Earth seismic tomographic models
No full textWe evaluate the resolution of whole Earth structure achieved by compressional wave traveltime data from the International Seismological Centre (ISC); the measure of resolution we employ, provided by the direct calculation of the model resolution matrix, is more rigorous than the traditional (and computationally cheaper) one obtained through synthetic/checkerboard tests. Our work completes the introductive study of Boschi (2003), where only mantle models derived with a very simple regularization scheme were considered. Here, we expand Boschi's database with measurements of compressional waves reflected by, or refracted through, the Earth's core mantle boundary (CMB) and core. In analogy with the work of Soldati et al. (2003), we treat CMB topography and heterogeneous outer core structure as free parameters of our inversions; analysing model resolution matrices, we attempt to explain the known discrepancy between deep Earth structure mapped by seismic waves reflected and refracted by the core

The effect of global seismicity on the polar motion of a viscoelastic Earth
No full textWe evaluate the polar drift of a stratified viscoelastic Earth, generated by 20 years of global seismicity (from the Centroid Moment Tensor catalog, 1977–1997). Our estimate is better than that of Soldati and Spada [1999] because it accounts for the effects, previously neglected, of earthquakes at depths larger than 80 km. In fact, we show that deep focus and intermediate-depth focus seismic events tend to affect the Earth's inertia tensor more significantly than shallow ones; specifically, we find that the mean rate of polar drift (evaluated over a 6-year time interval immediately following the seismic event) due to a vertical dip-slip source at the bottom of the asthenosphere (280 km depth in our model) is 5 times larger than that generated by an analogous source, located at the boundary between lithosphère and asthenosphere (80 km depth). We conclude, nevertheless, that global seismic activity is not able to alter significantly the rotational parameters of the Earth: according to our computations, the changes that it induces in the inertia tensor result in an average polar drift that is still significantly smaller than the observed one

Soldati) owes having become an entomologist. Material examined Holotype TUNISIA: ♂, “Zaghouan, 20–22.V.1995, M. Ouda leg. / Blaps teocchii m. n. sp. L. Soldati 2015, HOLOTYPE” (MNHN). Allotype TUNISIA: ♀, same data as holotype (MNHN). Paratypes TUNISIA: 1 ♂, same data as holotype (CS); 1 ♂, same data as holotype (CT). Description Length: 31.0–33.0 mm; width: 11.0–13.0 mm. Semi-gloss black. Oval-oblong (Fig. 5A–C). Upper surface covered with very fne, sparse and superfcial punctures, denser on head and pronotum. HEAD. Clypeus arcuately emarginated, with lateral angles right and protruding frontwards, leaving clypeolabial membrane partially visible. Clypeo-frontal suture reduced to thin gloss line. Middle of frons (disc) with faint transverse depression. Mentum transverse, coarsely punctate and slightly impressed in middle of anterior edge. Gula microshagreened, matte. Labium deeply notched in middle of front edge. ANTENNAE. Slender, barely reaching pronotal base when directed backwards (Fig. 5D). PRONOTUM. Broadest in its middle, with sides narrowed almost in straight line posteriorly and arcuately towards front. Anterior angles rounded. Posterior angles obtuse and blunt. External rim fne, complete on lateral margins but obliterated in middle of front edge and base. Disc slightly convex. Punctation fne, uniform, as on head. Carina of anterior foramen of pronotum thick and neck-shaped below. Episternum of prosternum superfcially wrinkled. Prosternal apophysis vertically bent just behind anterior coxae, then fat and non-protruding posteriorly. ELYTRA. Ovoid, broadest around its middle, depressed on disc. Upper surface smooth and covered with very fne and sparse punctures; background integument semi-gloss. Caudal extension at apex of elytra (mucro) measuring between 1.0 and 2.5 mm. Seen from above, mucro almost subparallel; deep suture fanked by two thick, coarsely transversely wrinkled ribs, slightly converging toward apex, apex ending in narrow apical gap (Fig. 5E). In lateral view, mucro regularly sloping up to apex (Fig. 5F). Seen from below, mucro regularly excavated, with sharp external edges and bottom transversally wrinkled. ABDOMEN. Ventrites wrinkled-punctate; anal ventrite densely punctate, with external rim complete and quite thick. LEGS. Protibiae long and fexuous. Mesotibiae curved. Inner face of pro- and mesotibiae widely grooved. Tarsi elongated and stout; claws long. Hind tarsi as long as ¾ of length of corresponding tibiae. SEXUAL DIMORPHISM.

Elytra slightly larger than pronotum in males. Pseudopleural carina only visible on anterior half from above in males, or on anterior third in females, because of transversal convexity of elytra. In lateral view, posterior declivity of elytra steeper in females. Mucro longer in males (2.5 mm) than in females (1.0 mm) (Fig. 5E, G). Rear edges of median and especially hind tibiae strongly denticulate in males. Male metatibiae fexuous and shallowly emarginated on inner face at middle third; straight and simple in females. AEDEAGUS. Parameres bottleneck-shaped on sternal face (Fig. 5H), with apex acuminate. In lateral view (Fig. 5I), parameres thick and convex at base, then narrowed almost in straight line up to apex. Bionomics Unknown. Distribution Tunisia. So far known only from the type locality of Zaghouan in Tunisia. Remarks This species belongs to the Blaps emondi species group (sensu Condamine et al. 2011). It is morphologically very similar to B. maldesi sp. nov. from Tunisia (see above for more information).Published as part of Laurent Soldati, Fabien L. Condamine, Anne-Laure Clamens & Gael J.

Posterior angles obtuse and blunt. External rim fne, complete on lateral margins, but briefy obliterated in middle of front edge and base. Disc quite convex. Punctation fne, uniform. Carina of anterior foramen of pronotum thick and neck-shaped below. Episternum of prosternum wrinkled near coxae and obliterate toward sides. Prosternal apophysis vertically bent just behind anterior coxae, then fat and non-protruding posteriorly. ELYTRA. Ovoid, broadest around its middle, fat on disc. Upper surface leathery and covered with extremely fne and sparse punctures. Pseudopleural carina only visible on anterior half from above because of transversal convexity of elytra. Caudal extension at apex of elytra (mucro) measuring less than 2.0 mm. Deep suture of mucro fanked by two thick, coarsely transversely wrinkled ribs, converging toward apex, apex ends in narrow apical gap (Fig. 3E). In lateral view, mucro regularly sloping up to apex (Fig. 3F). Below, mucro regularly excavated, with sharp external edges and bottom transversally wrinkled. ABDOMEN.

Inner face of pro- and mesotibiae widely grooved. Tarsi elongated; claws long. Hind tarsi approximately as long as one half of length of corresponding tibiae. SEXUAL DIMORPHISM.

Elytra slightly larger than pronotum in males. In lateral view, posterior declivity of elytra steep in males and subvertical in females.

Rear edges of median and especially hind tibiae strongly denticulate in males. Male metatibiae fexuous and shallowly emarginated on inner face; female metatibiae straight and simple. AEDEAGUS. Parameres bottleneck-shaped on sternal face (Fig. 3H), with apex acuminate. In lateral view (Fig. 3I), parameres thick and convex at base, then narrowed almost in a straight line up to apex. Bionomics The three known specimens were taken in the cedar forest of S’Gag (Algeria). Distribution Algeria. This species is currently known only from the type locality of S’Gag in the Aurès region. Remarks This species belongs to the Blaps emondi species group (sensu Condamine et al. 2011). It is morphologically most similar to B. teocchii sp. nov. from Tunisia. Blaps maldesi sp. nov. is most clearly separated from B. teocchii sp. nov. by having shorter antennae and tarsi, a wider pronotum and by the presence of a tuft of yellow bristles between abdominal ventrites 1 and 2. Until now, these two species have passed unnoticed in the collections because they superfcially look like small specimens of other species of the emondi group, especially when the specimens are prepared in the old-fashioned way, with the legs tucked under the body. Compared to other species in the emondi group, these two species are characterized by the following combination of characters: slender legs; long and fexuous fore-tibiae, with inferior face distinctly grooved; tarsi long; and bottleneck-shaped parameres of aedeagus.Published as part of Laurent Soldati, Fabien L.
