    We discuss the use of Agent-based Modelling for the development and testing of theories about emergent social phenomena in marketing and the social sciences in general. We address both theoretical aspects about the types of phenomena that are suitably addressed with this approach and practical guidelines to help plan and structure the development of a theory about the causes of such a phenomenon in conjunction with a matching ABM. We argue that research about complex social phenomena is still largely fundamental research and therefore an iterative and cyclical development process of both theory and model is to be expected. To better anticipate and manage this process, we provide theoretical and practical guidelines. These may help to identify and structure the domain of candidate explanations for a social phenomenon, and furthermore assist the process of model implementation and subsequent development. The main goal of this paper was to make research on complex social systems more accessible and help anticipate and structure the research process

    <abstract language="eng">A study of phylogenetic relationships of the genera of Mesembrinellinae and of the species of Eumesembrinella Townsend, 1931, on the ground of shared derived character states (synapomorphies) is presented. Resulting the following assumption: Laneella Mello, 1967 presenting sister group relationship with all other Mesembrinellinae, followed by Souzalopesiella Guimarães, 1977, M. peregrina Aldrich, 1922 that was isolated from Mesembrinella Giglio-Tos, 1893. Mesembrinella was considered paraphiletic, its species were judged in changeable positions at the bifurcation point of analysis of Albuquerquea Mello, 1967 with the tricotomic interrelationships of Thompsoniella Guimarães, 1977, Huascaromusca Townsend, 1918 and Eumesembrinella Townsend, 1931. The phylogeny of the genus Eumesembrinella shows E. cyaneicincta in basal position, followed by E. quadrilineata that showed sister group relationship wilh E. randa plus E. benoisti. Mesembrinella currani Guimarães, 1977 and Eumesembrinella benoisti (Séguy 1925) were revalided
