Phalacrichus max n. sp. (Coleoptera, Limnichidae) from Peru (America)

A species of the genus Phalacrichus Sharp is described as new, P max n. sp. collected at light in a flooded secondary forest near Iquitos, Peru. According to its externa1 morphology it seems closer to P spangleri Wooldridge, frorn which it can be separated by the puncturation of the head, the shape of the pronoturn, the pubescence. the pronotal tubercles and the aedeagus. Phalacrichus max n. sp. represents the 13th known species of this Neotropical genus.

Ochthebius (Enicocerus) aguilerai sp.n. from central Spain, with a molecular phylogeny of the Western Palaearctic species of Enicocerus (Coleoptera, Hydraenidae)

13 páginas, 21 figuras, 2 tablas.-- Articulo Open Access.We describe Ochthebius (Enicocerus) aguilerai sp.n. from central Iberia. The species belongs to the O. exsculptus group, including O. legionensis Hebauer & Valladares, O. halbherri Reitter, O. colveranus Ferro and O. exsculptus Germar. There are few consistent differences in external morphology among species of the group, but characters of the aedeagus allow the unequivocal recognition of the new species. A molecular phylogeny of the European species of subgenus Enicocerus based on fragments of four mitochondrial and two nuclear genes recognised O. aguilerai sp.n. as sister to the remaining species of the O. exsculptus group, which according to molecular clock estimations seems to have an Iberian origin in the Late Miocene (Tortonian). There are two genetically distinct lineages within O. exsculptus, one in South Spain and a second from the Pyrenees to Ireland, but the lack of consistent morphological differences between them, and the incomplete sampling of other Iberian populations of the species, prevents the recognition of distinct taxa.This work was funded with projects CGL2004-00028 and CGL2007-61665 to IR. We finally thank Pedro for the good times spent together.Peer reviewe

Agabus (Dichonectes) Parvulus Nov. Sp. de la Península Ibérica, y clave para la determinación de los Dichonectes Ibéricos

Es descriu una nova espècie d'Agabus sbg. Dichonectes, l'A.(Dichonectes) parvulus nov. sp. capturat en el Parc Nacional de les SIERRAS DE CAZORLA Y SEGURA (JAEN, ESPAÑA). Aquesta nova espècie queda situada entre els Mchonectes peninsulars en posició aïllada per la seva morfologia externa i la curiosa forma del seu sedeagus. S'inclou una clau per determinar les espècies ibèriques del sbg. Dichonectes.A new species of Agabus sbg. Dichonectes is described, the A.(Dichonectes) parvulus nov. sp. collected in the National Parc of the SIERRAS DE CAZORLA Y SEGURA (JAÉN, SPAIN). This new sp. is inserted between the species of the sbg. Dichonectes of the Iberian Peninsula in isolated Position by its external morphology and aedeagus. A key is inscluded to classify the species of the group of the Iberian Peninsula

Mobile learning: una experiencia colaborativa mediante códigos QR

[spa] La siguiente experiencia muestra las posibilidades educativas del uso del aprendizaje móvil y de códigos QR en el aula de Educación física de secundaria como herramienta para fomentar la práctica de actividad física saludable. La experiencia ha sido diseñada en forma de unidad didáctica colaborativa para el alumnado de segundo curso de educación secundaria obligatoria de dos centros educativos de Barcelona. El objetivo principal ha sido simular el ascenso al Everest mediante la realización de retos colaborativos de fuerza resistencia diseñados por el alumnado y convertidos en códigos QR. La suma de repeticiones de fuerza conseguidas de forma colaborativa entre el alumnado de ambos centros ha simulado en metros la ascensión al Everest. La experiencia se ha basado en la investigación educativa cualitativa y bajo un diseño de casos múltiple y ha utilizado una metodología colaborativa para la consecución del reto. Los resultados obtenidos han demostrado el potencial del aprendizaje móvil como herramienta educativa emergente facilitadora y motivadora del proceso de enseñanza aprendizaje.[eng] The experience presented in this article highlights the educational potential of using mobile learning and QR codes in a secondary physical education classroom to foster healthy physical activity. The experience was designed as a collaborative didactic unit for 13/14 year-old compulsory secondary education pupils from two schools in Barcelona, Spain. The main objective was to simulate a Mount Everest ascent by performing collaborative resistance strength challenges designed by the pupils and converted into QR codes. The total number of strength exercise repetitions that the pupils from both schools managed to do collaboratively simulated the number of metres climbed towards the summit of Mount Everest. The experience was based on qualitative educational research and had a multiple case-study design. Moreover, it used a collaborative methodology to accomplish the challenge. The results obtained show the potential of mobile learning as an emergent educational tool that is capable of facilitating and fostering the teaching-learning process
