Variación intra-específica en machos de Actinopus sp. (Mygalomorphae: Actinopodidae) del norte argentino

Abstract

“Intraspecific variation in males of Actinopus sp. ( Mygalomorphae: Actino- podidae) of northern Argentina”. Little is known about the diversity and morphology of the neotropical genus Actinopus Perty, 1833. On this work the focus is given to the intra-speci- fic variations of somatic (cephalothorax and sternum) and genital (bulbs) characters in a sam- ple of males of Actinopus sp. Geometric morphometric techniques were applied in order to quantify the shape change. The analysis of a subsample showed low levels of variation in both groups of characters. The results suggest a high level of conservatism of the genital and somatic characters on these males
