Phylogenetic relationships in Stephanopinae: systematics of Stephanopis and Sidymella based on morphological characters (Araneae: Thomisidae)

A matrix of 117 morphological characters scored for 77 terminal taxa was subjected to parsimony analysis under equal and implied weighting schemes Bayesian inference in order test the relationships between Stephanopis Sidymella species, as well its implications systematics subfamily Stephanopinae. sensitivity performed evaluate nodal stability. Our results indicate polyphyletism both genera topologies obtained allowed proposition following taxonomic acts: The “altifrons clade” is only group considered (stricto sensu), with species restricted Australian region; most from Neotropical region, hitherto attributed this genus, formed well-supported “pentacantha clade”, while two them, Central America, were recovered “championi clade”. latter shows significative evidences revalidation Paratobias gen. rev.; “cambridgei emerged I. punctata nested within, having all component transferred Isala. None distribution seems be part which occurs fact region closely related Coenypha. This has an increment three Stephanopis. Aside “lucida here other groups a single apart genus: “hirsuta “trapezia “angularis Si. rubrosignata. Morphological seem justify these new genera.
