“…Bardella et al (2010) examined the karyometry of different species of triatomines and noted significant differences between species. Those authors analyzed the subspecies T. i. melanosoma and described the same chromosomal features that we observed for T. infestans, corroborating the synonymy of T. i. melanosoma for T. infestans proposed by Gumiel et al (2003).…”

ABSTRACT. In this study, the karyometry of different Triatoma infestans populations from different states of Brazil was analyzed and compared with those of a population from Cochabamba. No significant differences were found between the population from Cochabamba and those from Brazil. These results are consistent with the origin of the T. infestans populations of Brazil by a founder effect from Cochabamba. Moreover, these findings also confirm that a founder effect occurred during the dispersal of T. infestans populations in different Brazilian states.

“…Th e method of relative warps and shape coordinates (BC: Bookstein's Shape Coordinates) developed by Bookstein (1991) for the analysis of morphometric variation based on landmark data gives a special help to taxonomists. At the present time, geometric morphometric studies have gained signifi cant support especially among anatomists (Lockwood et al 2002) and taxonomists (Rohlf 1993;Alibert et al 2001;Gumiel et al 2003) by the use of various morphological characters. Readers unfamiliar with the techniques are directed to Bookstein (1991), Rohlf (1999), Pavlinov (2001 and especially to O'Higgins (2000), Zelditch et al (2004) and Adams et al (2004) which cover the more technical aspects of these methods.…”

“…Since the 1970's, several authors have begun to use the insect wings especially in 2D morphometrical studies in systematics and phylogeny (Plowright & Stephen 1973;Rohlf 1993;Klingenberg 2003;Gumiel et al 2003). Because wings are solid or rigidly articulated structures they have become very useful tools for geometric morphometric studies (Pavlinov 2001).…”

B. (Sibiricobombus) niveatus and B. (Sibiricobombus) vorticosus are analyzed and compared with selected species of the subgenera Melanobombus and Mendacibombus. Different geometric morphometric methods based on wings landmark data show that there are no morphological differences between B. niveatus and B. vorticosus. These results support the hypothesis that B.niveatus and B. vorticosus should be regarded as conspecifi c. On the other hand, the wing shapes show signifi cant differences among the bumblebee species and subgenera that are coherent with their specifi c and subgeneric status. This approach may help future studies not only by contributing towards solving problems in systematics but also in understanding the fl ight mechanism of bumblebees. It also supports studies on the evolution of crossvein structure and on aerodynamics of different wing shapes in insects. Résumé. Analyse en géométrie morphologique des landmarks de forme d'ailes chezSibiricobombus Vogt (Hymenoptera : Apidae : Bombus Latreille). La variabilité morphométrique de Bombus (Sibiricobombus) sulfureus. B. (Sibiricobombus) niveatus et B. (Sibiricobombus) vorticosus est analysée et comparée à une sélection d'espèces parmi les sous-genres Melanobombus et Mendacibombus. Différentes méthodes de morphométrie géométrique, basées sur des landmarks pris sur les ailes, montrent qu'il n'y a pas de différence morphologique entre B. niveatus et B. vorticosus. Ces résultats confortent l'hypothèse selon laquelle B. niveatus et B. vorticosus doivent être considérés comme conspécifi ques. Par ailleurs, la forme des ailes des espèces et sous-genres de bourdons étudiés montre des différences signifi catives et cohérentes avec leur statut spécifi que et subgénérique. A l'avenir, cette approche pourra non seulement contribuer à la résolution de cas litigieux en systématique, mais également à la compréhension des mécanismes de vol chez les bourdons. Elle pourra également servir aux travaux sur l'évolution de la structure de la nervation alaire et sur l'aérodynamique des différentes formes d'ailes chez les insectes.

Introducción. Es importante determinar las especies de Anopheles pertenecientes al subgénero Nyssorhynchus, dado que allí se encuentran los vectores principales de malaria en Colombia. Objetivo. Utilizar la morfometría geométrica para evaluar la variación morfométrica de once especies del subgénero Nyssorhynchus, presentes en Colombia y la capacidad de diferenciar las hembras. Materiales y métodos. Los especímenes fueron obtenidos de mosquitos silvestres, series e isofamilias de hembras recolectadas en cebos humanos protegidos y fueron identificados en todos sus estadios asociados usando las claves convencionales. A partir de fotografías digitales del ala derecha de 336 ejemplares de las 11 especies se seleccionaron 12 puntos anatómicos. Los puntos se convirtieron en coordenadas, las cuales se procesaron mediante el análisis generalizado de Procrustes. Se obtuvieron variables de tamaño y conformación, las cuales fueron analizadas mediante estadísticas univariadas y multivariadas. Resultados. Las técnicas de morfometría geométrica demuestran que la división en secciones del subgénero Nyssorrhynchus no se correlaciona con la conformación de las alas y demostraron que sólo con 12 puntos anatómicos se logra diferenciar en sus respectivas especies el 97% de los especímenes de la sección Argyritarsis y el 86% de la sección Albimanus del subgénero Nyssorhynchus, de forma cuantitativa y sin ambigüedades. Además, se separaron los individuos de tres especies que habitan en simpatría en el Putumayo, difíciles de discriminar en el estadio de adulto hembra. Conclusión. La mayoría de especies de Anopheles (Nyssorhynchus) presentes en Colombia se pueden diferenciar al utilizar la morfometría geométrica como herramienta de apoyo a las claves convencionales. Palabras clave: Anopheles/anatomía e histología, clasificación, vectores de enfermedades, malaria, Colombia. Differentiation by geometric morphometrics among 11 Anopheles (Nyssorhynchus) in Colombia.Introduction. The correct identification of the Anopheles species of the subgenus Nyssorhynchus is important because this subgenus includes the main malaria vectors in Colombia. This information is necessary for focusing a malaria control program. Objective. Geometric morphometrics were used to evaluate morphometric variation of 11 species of subgenus Nyssorhynchus present in Colombia and to distinguish females of each species. Materials and methods. The specimens were obtained from series and family broods from females collected with protected human hosts as attractants. The field collected specimens and their progeny were identified at each of the associated stages by conventional keys. For some species, wild females were used. Landmarks were selected on wings from digital pictures from 336 individuals, and digitized with coordinates. The coordinate matrix was processed by generalized Procrustes analysis which generated size and shape variables, free of nonbiological variation. Size and shape variables were analyzed by univariate and multivariate statistics.
