Outside the pattern: Evolution of the genital asymmetry in Saicinae (Hemiptera: Heteroptera: Reduviidae)

Despite genital structures in insects being consistently important as systematic and taxonomy evidence, within assassin bugs (Heteroptera, Reduviidae) at least, the male and female genitalic structures of several subfamilies are poorly or totally unknown. The genital structure is mostly symmetric within Saicinae genera, but male genital asymmetry has been recorded in Gallobelgicus, Polytoxus, and recently Pseudosaica. The subfamily has been considered as closely related to Emesinae and Visayanocorinae but this hypothesis has never been tested using a comprehensive taxa sampling, being a constraint to test morphological traits changes or exploring characters' evolution hypotheses. Here, we compiled a morphological data set of 170 characters that includes external morphological characters and genitalia of both sexes of Saicinae which was analyzed cladistically including 55 terminals, comprising 16 genera (64% of the generic diversity), 43 species of Saicinae and 12 outgroups. Saicinae was recovered as polyphyletic, Saicireta correntina is recovered as sister-species of Empicoris armatus + Collartida (Emesinae), Oncerotrachelus, Carayonia (Visayanocorinae), and the Clade Saicinae sensu stricto. Carayonia orientalis is recovered as sister-species of Saicinae sensu stricto. Ancestral state reconstruction of symmetry of the male genitalia shows an ancestor with symmetric male genitalia, two independent emergences of asymmetrical male genitalia within Saicinae sensu stricto, and the asymmetrical endosomal sclerites appearing before the other asymmetric traits.Facultad de Ciencias Naturales y Muse

Buninotus palikur n. sp. (French Guiana), Caprilesia napuruna n. sp. (Ecuador), Caprilesia sikuani n. sp. (Colombia), and Pseudosaica charrua n. sp. (Argentina) are described. Detailed descriptions of coloration patterns, external morphology and genitalia are offered and discussed for each genus and species. Digital images of external morphological characters and of the genitalia are provided. Updated keys to the species of Buninotus, Caprilesia, and Pseudosaica are presented to facilitate the identification of the species.Facultad de Ciencias Naturales y Muse

Revisitando el género de chinches emboscadoras Neoanthylla Kormilev, 1951 (Reduviidae, Phymatinae)

Neoanthylla (Kormilev, 1951) es un género Neotropical de Phymatinae con tres especies válidas: Neoanthylla bucki (Kormilev), Neoanthylla horvathi (Handlirsch) y Neoanthylla peruviana Kormilev. Morfológicamente se caracteriza por el profémur alargado y ovalado con la superficie cuticular lisa y brillante; las procoxas largas y subiguales al mesofémur; la carina prosternal larga, alcanzando el margen anterior del mesosternum; y el abdomen entero posteriormente. Las especies de Neoanthylla están escasamente documentadas en la literatura y las estructuras genitales son desconocidas. Además, las especies brasileñas (N. bucki y N. horvathi) son conocidas sólo por hembras. Aquí, se revisa Neoanthylla, se actualizan las diagnosis de las especies válidas, se brindan imágenes de los holotipos de N. horvathi y N. peruviana, y se describe por primera vez el macho de N. horvathi, incluyendo los caracteres genitales.Neoanthylla (Kormilev, 1951) is a Neotropical genus of Phymatinae with three valid species: Neoanthylla bucki (Kormilev), Neoanthylla horvathi (Handlirsch), and Neoanthylla peruviana Kormilev. Morphologically, it is characterized by the elongated and oval profemur with the cuticular surface smooth and shiny; the procoxa long and subequal to the mesofemur; the prosternal carina long, reaching the anterior margin of the mesosternum; and the abdomen posteriorly entire. Neoanthylla species are scarcely documented in the literature, and the genital structures are unknown. In addition, the Brazilian species (N. bucki and N. horvathi) are known only by female specimens. Here, Neoanthylla is revisited, the diagnoses of the valid species are improved, images of the holotypes of N. horvathi and N. peruviana are provided, and the male of N. horvathi is described for the first time, including genital characters.Facultad de Ciencias Naturales y Muse

Learning and Teaching Biodiversity Through a Storyteller Robot

. This research project proposes the use of Child-Robot Inter action principles to boost the interest and engagement of young children in the biodiversity curriculum. We propose an architecture where a robot learns from children through an Interactive Story, while at the same time teaches them previous knowledge acquired in past interactions.info:eu-repo/semantics/publishedVersio

Migration and Human Capital: The Effect of Education on the Qualified Employment of Venezuelan Immigrants in Peru

This study analyzes the impact of Venezuelan immigrants’ human-capital on their occupational choice in Peru, in terms of job qualifications. Cross-sectional data were sourced from the National Survey to the Venezuelan Population in Peru, using ordered probit models for 2018 and 2022. The results show that immigrants with university education or previous job experience are overeducated for jobs requiring university education, in the Peruvian labor market, for both years, since they are more likely to obtain jobs with technical education requirements, the intensity of the phenomenon reduced in 2022. The study verifies the Venezuelan immigrants’ overeducation in the Peruvian labor market.Revisión por pare
