Figures 110–113 in Review of Grosphus Simon 1880 with description of Teruelius gen n a new buthid genus from Madagascar (Scorpiones Buthidae)

Figures 110–113. Biometric scaling of spiracles of sternite IV in Grosphus, Neogrosphus and Teruelius gen. n. Figures 110–111. Logarithmic scatter plots showing scaling of single spiracle area/ (carapace length)2 vs. carapace length in males (110), and females (111) of Grosphus, Neogrosphus and Teruelius gen. n. Spiracle length was largest diameter (approximately along mediolateral axis), width was smallest diameter (approximately along rostrocaudal axis). Area was from closed boundary curve: anterior edge of opening sharply delineated, posterior edge sometimes less sharp and fitted with spline curve extrapolating lateral edge curvature and tracing shadow of raised posterior margin. Brown line is least squares linear regression fit of scaling trends for Teruelius. R = Pearson correlation coefficient, and P value as indicated. Plotted points are means, error bars SE. Figures 112–113. Logarithmic scatter plots showing thermal (terrestrial temperature) scaling of spiracle area/ (carapace length)2 in males (112), and females (113) of Grosphus, Neogrosphus and Teruelius gen. n. Gray lines are least squares linear regression fits of scaling trends for all points. R = Pearson correlation coefficient, P value as indicated. Plotted points are means, error bars SE. Land surface temperatures at known collection sites were averaged over all sites for each species. Collection sites were extracted from published data and FMNH records. Temperatures were extracted from published model data of Chabot-Couture et al. (2014), who estimated annual mean daytime temperature by statistical processing and Kriging of remote sensing spectral radiance by AQUA satellite.
