The ratio between width of the metacoxal plate and metasternal wing (WC/WS) in the A. raffrayi group (incl. specimens of both sexes). Thick black line inside boxes represents medians, left and right box borders 25th (Q1) and 75th (Q3) percentiles respectively. Whiskers were calculated with the boxplot.stats function in R using the default coefficient value of 1.5 (drawn to the highest and lowest value within 1.5*IQD (Inter Quartile Distance = Q3-Q1) away from the 75th and 25th percentiles respectively). Note that this character fully separates A. raffrayi from A. pallidus.
