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 .
