Justification of synonymies. Mesabolivar eberhardi is a variable species but differences among populations are inconsistent and genetic p-distances are low as typical for intraspecific variation ( Huber 2000; Astrin et al. 2006). While most of González-Sponga’s drawings of his six “ Blechroscelis ” species clearly point towards Mesabolivar eberhardi , some remarkable deviations do occur. However, re-examination of González-Sponga’s material (by PAC) revealed that all those apparent differences resulted from varying angles of view and from inaccurate drawing. For example, the male palpal trochanter apophyses of “ B. copeyensis ” and “ B. andinensis ” are not slender as in González-Sponga’s drawings but short and thick as usual for the species (cf. fig. 773 in Huber 2000). The retrolateral process on the palpal femur of “ B. cordillerano ” is simple as usual (cf. fig. 773 in Huber 2000). The tips of the procursi vary widely in González-Sponga’s drawings but in all specimens they actually conform to the bifid structure distinctive for the species (cf. figs. 775–776 in Huber 2000). The same is true for the bulbal process (embolus) which is also distinctively bifid (cf. fig. 778 in Huber 2000). The chelicerae of M. eberhardi carry a highly distinctive pair of proximal lateral projections (cf. fig. 774 in Huber 2000); these are shown in all of González-Sponga’s drawings but in those drawings they appear more variable than they actually are. Finally, the epigynum of M. eberhardi has a long median groove (cf. fig. 780 in Huber 2000), also in specimens of “ B. acuoso ” and “ B. cordillerano ” (contrary to González-Sponga’s drawings where the grooves appear short).
