Figure 191 in Contributions to scorpion systematics. III. Subfamilies Smeringurinae and Syntropinae (Scorpiones: Vaejovidae)

Figure 191: Metasomal segment (I–IV) proportions for subfamily Smeringurinae (ratios = segment width / segment length). Data include both adult males and females combined. These data show that Smeringurus segments are significantly thinner than in the other three genera, not only showing complete separation between standard error ranges, but for all data points. Statistical difference between Smeringurus and Paruroctonus is indicated by significant standard error separation and the negligible variance analysis value (p-value). In addition, segment III is at least twice as long as wide (indicated by 0.500 triangle marker) and segment IV is in general three times as long as wide (indicated by 0.333 triangle marker). The other genera cluster together, with Vejovoidus and Paravaejovis exhibiting the most stocky metasoma. The data, which encompass all species currently defined in Smeringurinae, were gathered from measurements calculated in this study as well as published measurements, primarily from those sources where the species were originally described (i.e., most measurements are from type specimens). See Fig. 1 for explanation of histogram components.
