Crambus proteus has two closely related species (Bassi, 2012): C. attis Bassi and C. rossinii Bassi. They are characterized by their similar external appearance and genitalia of both sexes, C. proteus usually differing in the more ochreous tinge of the dark scales in forewings, in male genitalia the gnathos is only slightly longer than the uncus, the tegumen is S-shaped, the costal process of the valva is stronger and longer, the tip of the phallus is longer, and in female genitalia the lateral processes of the sterigma are pointed as opposed to rounded in C. attis and elongate in C. rossinii.Published as part of Bassi, Graziano, 2013, Notes on some Old World Prionapterygini Landry, 1995 (Lepidoptera: Pyraloidea, Crambidae, Crambinae), with descriptions of new species, pp. 131-160 in Revue suisse de Zoologie 120 (1) on pages 158-159, DOI: 10.5281/zenodo.611854

ETYMOLOGY: The new species is named in honour of Wolfram Mey of the MFNB, whose field expeditions in Southern Africa greatly helped to improve our knowledge of African Lepidoptera. DIAGNOSIS: Mesolia meyi flies along with M. uniformella Janse, 1922. The two share a similar wingspan, but the ground color of M. meyi is whitish black in males and dark brown in females (Figs 3, 4), compared to the uniformly brown spotted with greyish and dark brown of M. uniformella (Fig. 2). Male genitalia of M. meyi (Fig. 22) can be distinghuished from those of M. uniformella (Fig. 23) by the longer coremata and valvae, more crested tip of the uncus and more slender cornutus. In the female genitalia M. uniformella (Fig. 38) can be distinguished by the asymmetrical bilobed corpus bursae. DESCRIPTION (Figs 3-4): Wingspan: holotype 18 mm; males 17-21 mm; females 18-23 mm. Labial palpi 3 x longer than widest diameter of compound eye, white basally, blackish brown in proximal half, then with white patch and blackish tip; long scales brown. Maxillary palpi brown irrorated white and tipped with black. Frons conical, clearly produced, concave tip with irregular margin with two small teeth; white basally and brown distally in males, whitish with brown and blackish irroration in females. Male antennae serrate, ochreous brown in basal half and brown distally, with costa white. Female antennae simple, ochreous brown with costa concolorous and lightly annulated with black. Ocelli fully developed. Chaetosemata moderate. Head, patagium, tegulae, and thorax tricolored white brown and black, clearly lighter in males. Abdomen greyish white suffused brown, with first four tergites orange yellow. Legs white with tarsomeres white annulated brown; tibial spurs white, delicate. Forewings with well-defined hook; males with ground color white with dark brown and brown irroration; apex with s-shaped ochreous brown speckling and dark brown apical dot; median fascia ill-defined, black and brown; dorsally with black brown patch at 0.3; terminal line partial, brown; fringes with both short and long scales white tipped with black from apex to hook, from hook to tornus short scales white suffused pale yellow and long scales white except immediately below hook, white with black tip. Male hindwings white, distally suffused black, with terminal line near tornus black, thick; fringes with short scales pale yellow and long scales white. Female wings decidedly darker; forewings ground color brown to dark brown, with irregular whitish irrorations except for whitish costal patch at 0.7 and, below hook, whitish suffused dark brown subterminal area, with two terminal dots; dark brown apical dot always visible, as in males; fringes white and black above hook, black and golden brown at hook and golden brown and whitish below hook. Female hindwings dark brown suffused golden brown, paler basally; fringes whitish, with short scales tipped with blackish. Sclerotizations of male abdominal segment VIII as shown in figure 22. Coremata (Fig. 15) double, 0.7 length of valva, flat, with upper structure large and arched and ventral structure larger and L-shaped.

(11) P. banaadirensis sp. n., holotype, wingspan 21 mm. (12) P. somala sp. n., holotype, wingspan 16 mm. MALE GENITALIA (Fig. 22): Uncus subcylindrical, curved; crest-like apical process broad, with few thickened setae. Gnathos 0.6 length of uncus, with pointed upturned tip. Tegumen subtriangular. Juxta cup-shaped. Pseudosaccus moderate. Valva elongated; cucullus rounded; costa more thickly sclerotized, without projections; sacculus moderately sclerotized. Phallus short, thickened; vesica with elongated cornutus at about half length of phallus. FEMALE GENITALIA (Fig. 37): Papillae anales thin, dorsally larger. Apophyses posteriores long and sclerotized. Abdominal segment VIII with subtriangular sclerotization and membranous sternite. Apophyses anteriores 1.4 longer than apophyses posteriores, with tiny attachment to abdominal segment, subtriangular enlargement at 0.1 from base, then narrow. Ostium bursae bulged, lightly sclerotized. Ductus bursae 0.44 length of corpus bursae, moderately sclerotized. Corpus bursae bilobed; proximal sac wrinkled, with long, narrow, longitudinally oriented striae, lightly slerotized and spiculated; distal sac delicately wrinkled, with ductus seminalis emerging at its tip. DISTRIBUTION: Botswana, Namibia. REMARKS: In the original description of M. uniformella (Janse 1922:7) the paratypes from Umvuma are all females. However, I studied a male “cotype” (1591 TMSA) with the label “Umvuma, Rhod[esia], 20. XII.[19]17, A.J. T. Janse”. Thus, it seems that one of the two paratypes cited as females was in fact a male. M. uniformella is distributed in Botswana, Namibia, RSA, and Zimbabwe.Published as part of Bassi, Graziano, 2013, Notes on some Old World Prionapterygini Landry, 1995 (Lepidoptera: Pyraloidea, Crambidae, Crambinae), with descriptions of new species, pp. 131-160 in Revue suisse de Zoologie 120 (1) on pages 136-140, DOI: 10.5281/zenodo.611854
Afrocharltona Bassi 2021, gen. n.
No full textAfrocharltona gen. n. Figs 7-11, 13, 17-19 Type species: Afrocharltona oblongissima sp. n. Diagnosis: In the adult the slender forewing distinguishes Afrocharltona from Charltona. Some Prionotalis [i.e. P. balia (Tams, 1932)] also have forewing yellow marbled with brown, but their apex of forewing is more pointed. In the male genitalia the combination of modified uncus and the very long and narrow valva represents a distinctive feature. In the female genitalia the lateral extension of medium length branching off in the middle of the ductus bursae and the ductus seminalis originating close to the lateral extension, are unique among related genera except for the prepiella species complex in the inornata group in Ancylolomia (Bassi & Trematerra, 2014). In this complex, however, the lateral extension is always very thin. The holotype and the female paratype from Zambia of A. oblongissima are barcoded, showing intraspecific distance of 1.27% and distance of 9.36% from Charltona tritonella (Hampson, 1898) and 7.74% from Charltona plurivittalis Hampson, 1910. However, the paucity of available barcoded specimens of Ancylolomia and allied genera does not allow a comprehensive DNA comparison, and in the future more molecular markers should be analysed to be conclusive on the relationships to other genera of Ancylolomiini. Etymology: The generic name is a combination of afro (from Africa) and Charltona, the probably closest genus. The gender of the new genus is feminine. Description: Medium to large species, with labial palpi rather short (2.5 - 3 x eye diameter in side view), ocelli and chaetosemata poorly developed, narrow forewing with rounded apex and arched termen. Male genitalia. Uncus slightly longer than gnathos (1.1 x), heavily bulged dorsally and with blunt and wrinkled apex. Gnathos subtriangular, slightly upcurved apically. Tegumen with slender arms, tegumen roof 0.3 of tegumen arm length. Vinculum v-shaped, moderately produced dorsally. Juxta suboval, more or less folded medially. Pseudosaccus a small plate fused with juxta. Valva strongly elongated, tapering towards apex; costal process always developed over cucullus. Phallus stout, 0.6 x valva length, with phallobase downcurved. Female genitalia. Papillae anales subtriangular, rounded ventrally. Apophyses well developed, roughly the length of papillae anales. Ostium concave, with sclerotized edge. Ductus bursae elongated, sclerotized and bearing a narrow lateral extension. Ductus seminalis originating at the middle of ductus bursae. Corpus bursae oval, wrinkled. Biology: Unknown. Distribution: Central Africa and Northern part of Southern Africa.Published as part of Bassi, Graziano, 2021, New genera and species of Afrotropical Ancylolomiini Ragonot, 1889 (Lepidoptera: Pyralidae sensu lato: Crambinae), pp. 477-486 in Revue suisse de Zoologie 128 (2) on pages 477-479, DOI: 10.35929/RSZ.0058, http://zenodo.org/record/564016

A high-order Discontinuous Galerkin method for natural convection problems
No full textDiscontinuous Galerkin (DG) methods have proved to be very well suited for the construction of robust high-order numerical schemes on unstructured and possibly non conforming grids for a wide variety of problems. In this paper we consider natural convection flow problems and present a high-order DG method for their numerical solution. The governing equations are the incompressible Navier-Stokes (INS) with the Boussinesq approximation to represent buoyancy effects and the energy equation to describe the temperature field.
The method here presented is an extension to natural convection flows of a novel high-order DG method for the numerical solution of the INS equations, recently proposed in Bassi et al. . The distinguishing feature of
this method is the formulation of the inviscid interface flux which is based on the solution of local Riemann problems associated with the artificial compressibility perturbation of the incompressible Euler equations. The discretization of the viscous term follows the well established DG scheme named BR2 The method is fully implicit and the solution is advanced in time using either a first order backward Euler or a second order Runge-Kutta scheme.
To assess the capabilities of the DG method presented in this paper we computed second-, third- and fourth-order space-accurate solutions of several benchmark problems on natural convection in two-dimensional cavities

Basic fibroblast growth factor-induced proliferation of primary astrocytes
No full textWe recently reported that the marked decrease in cellular ceramide in primary astrocytes is an early event associated with the mitogenic activity of basic fibroblast growth factor (bFGF) (Riboni, L., Viani, P., Bassi, R., Stabieini, A., and Tettamanti, G. (2000) GLIA 32, 137-145). Here we show that a rapid activation of sphingomyelin biosynthesis appears to be the major mechanism responsible for the fall in ceramide levels induced by bFGF. When quiescent astrocytes were treated with bFGF, an increased amount of newly synthesized ceramide (from either l-[(3)H]serine or [(3)H]sphingosine) was directed toward the biosynthesis of sphingomyelin. Conversely, bFGF did not appear to affect ceramide levels by other metabolic pathways involved in ceramide turnover such as sphingomyelin degradation and ceramide biosynthesis, degradation, and glucosylation. Enzymatic studies demonstrating a relevant and rapid increase in sphingomyelin synthase activity after bFGF treatment have provided a convincing explanation for the activation of sphingomyelin biosynthesis. The bFGF-induced increase in sphingomyelin synthase appears to depend on a post-translational activation mechanism. Moreover, in the presence of brefeldin A, the activation of sphingomyelin biosynthesis was abolished, suggesting that the enzyme is located in a compartment other than the Golgi apparatus. Also the phosphatidylcholine-specific phospholipase C inhibitor D609 exerted a potent inhibitory effect on sphingomyelin biosynthesis. Finally, we demonstrate that inhibition of sphingomyelin biosynthesis by brefeldin A or D609 led to a significant inhibition of bFGF-stimulated mitogenesis. All this supports that, in primary astrocytes, the early activation of sphingomyelin synthase is involved in the bFGF signaling pathway leading to proliferation

ETYMOLOGY: The new species is named in honour of Konrad Ebert of the MFNB, co-collector of large series of Lepidoptera during the MFNB expeditions in Southern Africa. DIAGNOSIS: P. eberti (Fig. 8) differs from P. amathusia (Fig. 7) in having a welldefined yellow and greyish brown forewing coloration and short rami in male antennae. In male genitalia (Fig. 25) the uncus is more distinctly curved, with strong tip and broad lateral process, the phallus is shorter, and the juxta is well sclerotized, even dorsally. In female genitalia (Figs 39, 40) the ductus bursae is membranous and on the corpus bursae the proximal patch is rounded. DESCRIPTION (Fig. 8): Wingspan: male 23 mm, females 24-28 mm. Labial and maxillary palpi 3 x as long as widest diameter of eye, greyish brown. Antennae bipectinate in males, simple in females; rami in males brown and moderately developed, costa bronze brown, silver bordered. Frons clearly produced, ending in corneous tooth, greyish brown. Ocelli small. Chaetosemata brown. Patagium medially white, brown laterally. Tegulae yellow with distal margins pale yellow. Thorax laterally brown, medially white.
