Abstract: A cladistic analysis of tribe Attacobiini (Corinnidae, Corinninae) with 17 taxa and 109 characters is presented. The outgroup is composed by four species (Castianeira aff rubicunda ACR; Xeropigo cotijuba; Septentrinna yucatan and Falconina gracilis) all of them represented by males and females. The ingroup is represented by 13 Attacobiini species, seven of which represented by both sexes (Attacobius TOC; A. attarum; A. verhaaghi; A. lamellatus; A. uiriri; A. blakei and A. carranca), three represented only by females (A. luederwaldti; A. nigripes and A. kitae) and three represented only by males (Ecitocobius comissator; Attacobius PAR and A. tucurui). Regarding to terminals, the present data matrix represent an increase of two species in relation to a previous analysis of the Tribe. The availability of data was improved by adding character states on genitalic features for three terminals, of which the counterpart sex was unknown at the time in which that previous analysis was made (males of A. verhaagui and females of A. blakei and A. uiriri). Furthermore, several characters used in the previous analysis were re-interpreted and some new characters were proposed. A single tree was obtained under equal weights. Attacobinni and Attacobius were retrieved as monophyletic groups but the groups of species of Attacobius depicted here are considerably different from those recognized in the previous analysis. The exact solution under equal weights and all characters running unordered resulted in a fully resolved, single most parsimonious tree. As in the previous analysis, the bettersupported clades were Attacobiini and Attacobius. However, the groups of Attacobius species recovered here are considerably different from the ones recovered previously, with the exception of an apical clade composed by A. nigripes, A. kitae, A. attarum and A. luederwaldti, which was recognized in both analyses as the best supported group within the genus.
