Group goloboffi

Diagnosis. The species in the group goloboffi are readily recognized by discontinuous thoracic fovea that is interrupted in middle (Ríos-Tamayo & Goloboff, 2018, fig. 42 A) and the sternum with a deep central depression (Ríos-Tamayo & Goloboff, 2018, fig. 42 B). The resemble all other species of type II morphology proposed by Ríos-Tamayo & Goloboff, 2018 (which include most species described here) by triangular shape of the post-labial sigilla, sternal sigilla I–II elongated, and, in females, by the abundant retrolateral thorns on tibia II and by the lobed spermathecae. They resemble A. crassipes (Fig. 107 A), A. dubiomaculatus (Fig. 112 A) and A. laventana (Fig. 129 A), included on group crassipes¸ by the PA continuous to PI. Females of group goloboffi share with A. dubiomaculatus (Fig. 112 D–H) and A. laventana (Fig. 129 D) the similar shape of receptacles. They differ from A. laventana by the absence of lateral swelling on receptacles.

Species included. Actinopus goloboffi Ríos, 2014; Actinopus balcarce Ríos-Tamayo & Goloboff, 2018; Actinopus excavatus Ríos-Tamayo & Goloboff, 2018 .
