Indicatti leg. ( IBSP 114467 ) . Etymology. The specific name refers to musician Philip Hansen Anselmo, or Phil Anselmo, the main singer of Pantera, one of the most respected trash metal bands of the world. Diagnosis. Males of Actinopus anselmoi differ from those of A. reznori ( Fig. 168 A–C) by the inconspicuous PA; presence of only one keel on prolateral copulatory bulb and serrated area ventrally located on prolateral embolus ( Fig. 171 A–C).
