The spine armament of the legs as an important means for the characterisation of the genera of Corydiinae and their relationships (Blattodea, Corydiidae).

The Palaearctic species of Corydiinae having no apical spine on the femora of the frontleg (48 species distributed to the genera Heterogamisca, Heterogamodes, Hemelytroblatta, Leiopteroblatta, Mononychoblatta, Nymphrytria, Psammoblatta) were studied in mainly three characters: tibia armament, features of the right phallomere, and distribution of bristles on the subgenital plate. The results suggest considerable changes in the classification with now 5 genera and several subgenera: (1) Heterogamodes with subgenera Heterogamodes, Heterogamisca, and Atuberculoblatta subgen. nov.

Revision of the genus Luridiblatta (Blaberoidea, Ectobiidae, Ectobiinae).

The present paper deals with the revision of Luridiblatta a genus having an almost circum-mediterranean distribution. The genus contains 10 species of which 7 are new; they can be aligned to 3 species-groups: the longitubulata-group with the species L. longitubulata sp.

Cockroach (Blattodea, Blaberoidea) fauna of the Maltese Islands, with descriptions of two new species.

Cockroach (Blattodea, Blaberoidea) fauna of the Maltese Islands. Hitherto seven species of cockroaches were known from the Maltese Archipelago (Schembri 1980): four of them are synanthropic species introduced by man: Blatta orientalis, Blattella germanica, Periplaneta americana and Supella longipalpa; the remaining three are indigenous species: Ectobius kraussianus, Loboptera decipiens and Polyphaga aegyptiaca. The earlier reports almost exclusively concern the largest island Malta; only one report (L.

First and second COVID-19 waves in Brazil: A cross-sectional study of patients' characteristics related to hospitalization and in-hospital mortality.

Background: Background The second wave of the COVID-19 pandemic was more aggressive in Brazil compared to other countries around the globe. Considering the Brazilian peculiarities, we analyze the in-hospital mortality concerning socio-epidemiological characteristics of patients and the health system of all states during the first and second waves of COVID-19.

Methods: We performed a cross-sectional study of hospitalized patients with positive RT-PCR for SARS-CoV-2 in Brazil.

Biomechanics of tendrils and adhesive pads of the climbing passion flower Passiflora discophora.

The climbing passion flower Passiflora discophora features branched tendrils with multiple adhesive pads at their tips allowing it to attach to large-diameter supports and to flat surfaces. We conducted tensile tests to quantify the performance of this attachment system. We found that the force at failure varies with substrate, ontogenetic state (turgescent or senescent), and tendril size (i.
