Selenops banksi group Muma, 1953

Diagnosis Males of the Selenops banksi group can be distinguished from other species by the short embolus beginning around 8–9 o’clock, and having an embolic apophysis which is obscured by the embolus in ventral view ( Figures 3 (a–h) and 5(a–f)). Females of the group can be separated from other species by the strongly sclerotised copulatory ducts with several turns, with inconspicuous primary spermathecae, a median lobe or septum, and medially located epigynal pockets ( Figure 6 (a–d, f–g)). Both males and females have the sternum longer than wide and the labium truncated with rounded anterior edges ( Figure 2 (g,k–l, q)).
