Frons and vertex entirely covered with dense coarse punctures, with golden pubescence. Antennal calli and supraorbital pores indistinguishable. Eyes large, elongated, inner margin straight. Interocular distance subequal to maximum eye length. Frontal and anterofrontal carinae forming a single triangular structure, punctured as vertex, with lateral margins raised and slightly bent outward, merged medially above antennal insertion, forming a short central carina.

Metatarsal claws appendiculate.</p> <p> <b>Abdomen:</b> Shiny, pubescent, with five visible ventrites. Female genitalia similar to <i>L. triplehorni.</i></p> <p> <b>Etymology:</b> The specific epithet is in honor of Dr. Cleide Costa,on the occasion of her 80 th birthday, for dedicating her career to the study of Coleoptera.</p> <p> <b>Geographical distribution:</b> Southwest Paraná, Brazil.</p> <p> <b>Remarks:</b> Species of <i>Laselva</i> and <i>Andersonaltica</i> Linzmeier & Konstantinov, 2012 share the shiny elytral surface, punctures forming nine striae, and absence of pronotal antebasal transverse impression. They are differentiated by having (<i>Andersonaltica</i> in parenthesis) antennal calli indistinguishable (antennal calli small, generally nearly indistinguishable), antenna filiform (antenna forming a tight club), humeral calli well developed (humeral calli absent or poorly developed), posterior wings present (apterous) and procoxal cavities open posteriorly (procoxal cavities closed posteriorly).</p> <p> Among the Monoplatina genera, <i>Laselva</i> species are very similar to those of <i>Deciplatus</i> Linzmeier & Konstantinov, 2009.They share similar body size, proportions of pronotum, pubescence on elytra, procoxal cavity opened posteriorly and metatarsus inserted subapically. These genera can be easily differentiated by the number of antennomers, 11 in <i>Laselva</i> and 10 in <i>Deciplatus.</i> Surprisingly, some of the main features that separate <i>L. cleidae</i> sp. nov., from <i>L. triplehorni,</i> such as the shape of the anterofrontal and frontal carina and the antenal callus indistinguishable, besides the female genitalia, are very similar among <i>L. cleidae</i> sp. nov., and <i>Deciplatus</i> species. The female genitalia of <i>L. triplehorni</i> and <i>L. cleidae</i> sp. nov., are identical, not being an important character to differentiate them. In a recent study, Furth (2019) pointed out that he could not use the male and female genitalia to separate two <i>Cerichrestus</i> Clark, 1860 species because he did not find enough morphological differences. This genus also belongs to Monoplatina and, as mentionated in Furth’s paper, other researcher had the same experience studying this group. Apparently, in Monoplatina male and female genitalia do not provide informative taxonomic characters.</p> <p> Since Chapuis (1875), procoxal cavities, whether opened or closed, have been suggested as a character to separate Oedyonichina (opened posteriorly) from Monoplatina (closed posteriorily). Besides, other caracteristics used to define Monoplatina are punctured-striate elytra and the globosely swollen visible on tarsomere IV of metatarsus (Scherer, 1983; Linzmeier & Konstantinov, 2012), this last characteristic also shared with Oedyonichina species. However, <i>Laselva</i> and <i>Deciplatus</i> have the procoxal cavities opened posteriorly and were included in Monoplatina by Furth (2007) and Linzmeier & Konstantinov (2009). Currently, it is unclear if this character changed in some Monoplatina genera or if these two genera do not belong to this taxon. As Monoplatina is very diverse, poorly studied and no phylogenetic studies exist, this issue, as well as evolutionary history of Monoplatina, may be resolved based on a comprehensive phylogentic study.</p>Published as part of <i>Rech, Tarcila & Linzmeier, Adelita Maria, 2020, First species of Laselva Furth from Brazil (Chrysomelidae: Galerucinae: Alticini), pp. 1-4 in Papéis Avulsos de Zoologia 60 (9)</i> on pages 1-4, DOI: 10.11606/1807-0205/2020.60.special-issue.09, <a href="http://zenodo.org/record/4614235">http://zenodo.org/record/4614235</a>
Genomics and synthetic biology as a viable option to intensify sustainable use of biodiversity
No full textThe Amazon basin is an area of mega-biodiversity. Different models have been proposed^1-8^ for the establishment of an effective conservation policy, increasing sustainability and adding value for biodiversity. Currently, a broad spectrum of technologies from genomics to synthetic biology is available, and these permit the collection, manipulation and effective evaluation of countless organisms, metabolic pathways and molecules that exist as potential products of a large, biodiverse ecosystem. The use of Genomics and synthetic biology may constitute an important tool and be a viable option for the prospection, evaluation and manipulation of biodiversity as advocated as well as be useful for developing methods for sustainable use and the production of novel molecules
Croci, libertà religiosa e simboli sulle vette: una riflessione sociologica
No full textThis contribution presents summit crosses as cultural objects of artistic and landscape value, as well as of humble affection for individuals and communities, but above all as markers of the territory in the perspective of tourist promotion-commercialisation. Their contestation in the communicative and public sphere illustrates that typical mechanism of religious freedom that, in the contemporary context, opposes freedom of religion to freedom from religion

L'incompetenza cervicale quale fattore di rischio di parto pretermine: ruolo del cerchiaggio cervicale nell'attuale pratica ostetrica
No full textIl parto pretermine (PP)costituisce ad oggi la principale causa di mortalità e morbilità neonatale. Tra i fattori di rischio di PP vi è anche l'incompetenza cervicale (IC), la cui diagnosi viene formulata prevalentemente durante la gravidanza e si basa sul reperto ecografico di modificazioni morfometriche della cervice. Alla luce delle attuali evidenze scientifiche, in presenza di significative modificazioni morfometriche del collo uterino, il cerchiaggio dovrebbe essere raccomandato quando: 1) età gestazionale < 24 settimane; 2) anamnesi con elevato rischio"ex ante" di PP; 3) lunghezza residua del collo non superiore ai 2 cm; 4) esclusione preliminare di anomalie fetali, infezioni del tratto genitale inferiore, contrazioni uterine
