Myrmecotypus haddadi Perger & Rubio, 2021b: 182 , fig. 23 (holotype, ♂, BOLIVIA: Santa Cruz department, Santa Cruz de la Colina, Urubo ; in Zoological Museum Hamburg, University of Hamburg, Germany , ZMH-A0015356, not examined).

Diagnosis. Males of M. haddadi resemble those of M. niger by the presence of a sclerotized RTP but can be recognized by the RTP being elongated, sclerotized and excavated ( Fig. 4G–I ), whereas it is hook-shaped in M. niger ( Fig. 8G, H ); females can be recognized by the epigyne with two large circular copulatory openings and two small posterior transverse sutures ( Fig. 4J ).

Description. See Perger & Rubio, 2021.

Variation. Length (1♂) total 3.82, carapace 2.06, femur I 0.90; (2♀) total 3.77–4.02, carapace 2.11–2.24, femur I 0.90–1.04.
